Pathology – Breast Screening
The objective of screening is to detect DCIS or early invasive cancer. NHS mammography screening initiative Women between the ages of 50 and 70 are invited for screening every three years. • By 2012, this will encompass women aged 47 to 73. The screening test is a mammography that detects abnormal calcifications or masses in the breast. Evaluation clinic Approximately 5% of women exhibit abnormal mammography results and are subsequently sent to an assessment center for additional evaluation. • This may need further mammograms or an ultrasound, succeeded by sample of the anomalous region, typically via core biopsy.
Histopathology
Core biopsies obtained from breast screening patients are assigned a B code ranging from 1 to 5. B1 denotes normal breast tissue. This typically indicates that the biopsy overlooked the region of interest. B2 is a core exhibiting a benign anomaly. This is suitable for several lesions, including fibromas, fibrocystic changes, sclerosing adenosis, and fat necrosis. B3 is a lesion with indeterminate malignant potential. This category mostly comprises lesions that may be benign at their core but exhibit heterogeneity or possess a slightly elevated risk of a nearby malignancy. This is suitable for cores exhibiting flat epithelial atypia, in situ lobular neoplasia, atypical ductal hyperplasia, partially sampled papillomas, phyllodes tumors, and radial scars. B4 is a core exhibiting characteristics indicative of malignancy; nonetheless, a definitive diagnosis is unattainable due to factors such as inadequate aberrant tissue or compression of the biopsy. B5 is a core biopsy exhibiting definitive characteristics of malignancy. This is categorized either B5a for ductal carcinoma in situ (DCIS) or B5b for invasive cancer.
Administration • B1: rebiopsy. • B2: provide reassurance and revert to standard recollection. • B3: resection of the anomalous region. • B4: rebiopsy or excision of the anomalous region. • B5: surgical resection via extensive local excision or mastectomy. Efficacy • According to published statistics, the NHS breast screening program saves approximately 1,250 lives annually.

Pathology - Radial scar
Definition • A benign sclerosing breast lesion distinguished by a central area of scarring encircled by a radiating margin of proliferative glandular tissue. Radial scars vary in size from minuscule microscopic lesions to bigger, clinically discernible masses. Lesions above 1 cm in size are occasionally referred to as 'complex sclerosing lesions.'
Epidemiology • Radial scars are rather prevalent lesions. • Incidence rates fluctuate significantly based on their definition.
The aetiology and pathophysiology of radial scars remain mostly unknown. One concept posits that they signify a reparative process in reaction to regions of tissue injury in the breast.
Presentation • Large radial scars are typically identified on mammography as stellate or spiculated masses. They can nearly replicate the appearance of a cancer. Macroscopy • Radial scars present as stellate, firm lumps that appear to infiltrate the adjacent parenchyma. • They can be readily mistaken for invasive carcinomas upon macroscopic examination.
Histopathology • Radial scars are symmetrical, stellate lesions of the breast with a distinctive zonal architecture. The lesion's center (the nidus) consists of tight collagen bundles and elastic tissue containing entrapped, randomly organized tubules. • Encircling the nidus are radially oriented clusters of ducts and lobules, each directed towards the center of the lesion. The ducts and lobules in this region generally display pronounced benign alterations, such as fibrocystic change, sclerosing adenosis, and significant usual epithelial hyperplasia.
Prognosis: Radial scars are classified as benign lesions; yet, their existence is linked to a twofold elevated risk of later breast cancer development

Pathology - Intraductal papilloma
A benign papillary tumor originating in the ductal system of the breast. Papillomas may arise throughout the ductal system, with a preference for either small terminal ductules (peripheral papillomas) or big lactiferous ducts (central papillomas).
Epidemiology • Prevalent. • Predominantly observed in women aged 40 to 59.
Aetiology • Considered to be neoplastic proliferations of glandular and stromal breast tissue.
Presentation • The majority of women with central papillomas have nipple discharge. • Minor peripheral papillomas typically manifest as a breast lump.
Macroscopy: Large papillomas appear as fragile lumps within an enlarged duct.
Cytopathology • Smears obtained from nipple discharge may exhibit branching papillaroid clusters of epithelial cells indicative of the diagnosis.
Histopathology • A papillary mass is observed with a ductal space. • The papillae are broad and rounded, allowing the fronds to interlock seamlessly. • Each frond is rich in stroma, consisting of blood vessels and fibrous tissue. • The epithelium enveloping the fronds is bilayered, comprising inner columnar epithelial cells and outer myoepithelial cells.
Prognosis: Benign lesions; nonetheless, several studies indicate that women with papillomas exhibit a twofold greater chance of developing future invasive breast cancer.

Pathology - Duct ectasia
Inflammation and dilatation of big mammary ducts
Epidemiology: Prevalent among adult women throughout all age groups. Etiology • Ambiguous. Although infection may complicate duct ectasia, it does not appear to be the primary cause.
Presentation • Nipple discharge is the predominant presenting symptom. The discharge may be transparent, creamy, or blood-tinged. More severe cases may result in pain, a palpable breast lump, and nipple retraction.
Macroscopy: The subareolar ducts exhibit visible dilation and are filled with viscous secretions. Cytopathology Smears derived from a nipple discharge sample exhibit proteinaceous debris and macrophages. Ductal epithelial cells are typically absent. Histopathology • The subareolar ducts are distended and contain proteinaceous substances and macrophages. • Periductal chronic inflammation and fibrosis are also observed.
Prognosis: Duct ectasia is a nonmalignant disorder with no elevated risk of cancer.

Pathology - Polycystic Ovary Syndrome
Definition: A metabolic syndrome characterized by testosterone excess, ovulatory dysfunction, and, in certain women, the presence of polycystic ovaries.
Epidemiology • Prevalent, impacting approximately 5% of women. Aetiology Insulin resistance seems to be the principal underlying reason
Pathogenesis • Insulin resistance, obesity, and increased androgen synthesis by the ovaries. • Androgens contribute to hirsutism, acne, and irregular follicle maturation. • Irregular follicle maturation may result in polycystic ovaries in certain women. • Chronic anovulation leads to subfertility and decreased estrogen production. • Prolonged estrogen exposure results in endometrial hyperplasia and increases the chance of developing endometrial intraepithelial neoplasia and endometrial carcinoma
Presentation • Subfertility is a prevalent manifestation. • Certain women exhibit hirsutism and acne.
Radiology • Polycystic ovaries may be observed in certain women, but not universally. Biochemistry • Increased blood androgen levels. • Diminished glucose tolerance or overt diabetes.
Prognosis • The primary concerns are the difficulties linked to obesity and the possibility of endometrial carcinoma. • Weight loss, insulin-sensitizing medications, and progesterone therapy all contribute to mitigating these complications.

Pathology - Pelvic inflammatory disease
Definition: An infection of the upper female vaginal canal.
Epidemiology • The majority of instances occur in young sexually active women aged 15 to 25. The true incidence is challenging to ascertain due to numerous undiagnosed instances.
Aetiology • The majority of cases result from ascending infections caused by either Chlamydia (C.) trachomatis or Neisseria (N.) gonorrhoeae. Both organisms are sexually transmitted microorganisms. • Cases not linked to sexually transmitted infections are frequently connected with intrauterine devices or retained products of conception following childbirth or miscarriage.
Presentation • Typically, there are enduring symptoms of pelvic discomfort, dyspareunia, and post-coital or intermenstrual bleeding. • Severe instances may result in an acute illness characterized by fever, abdominal pain, and peritonitis. 2 It is important to recognize that numerous women remain asymptomatic and consequently undetected.
Complications • Infertility: the likelihood of infertility escalates with each occurrence of infection. Women who experience three or more bouts of pelvic inflammatory disease (PID) have a 40% likelihood of infertility. • Ectopic pregnancy: the chance is increased sixfold, perhaps due to deformation and scarring of the fallopian tubes. • Persistent pelvic pain and painful intercourse

Pathology - Ovarian carcinomas
Definition: A collection of malignant epithelial tumors originating in the ovary.
Epidemiology • Rare, however a predominant cause of cancer-related mortality owing to its delayed presentation.
Aetiology • High parity and the utilization of oral contraceptives are consistently linked to a diminished risk of ovarian cancer. • Post-menopausal women using oestrogen replacement treatment have an elevated risk. • Emerging evidence indicates that obesity correlates with an increased risk.
Carcinogenesis • Recent morphological and genetic evidence indicates that ovarian carcinomas can be classified into several types based on their probable origin and behavior. One group (low-grade serous, mucinous, Brenner) has indolent behavior and infrequently demonstrates TP53 mutations. Certain workers hypothesize that these tumors originate from paraovarian Müllerian epithelium via a progression from benign cystadenoma to borderline neoplasm to invasive carcinoma. The second category, comprising high-grade serous, high-grade endometrioid, and undifferentiated carcinomas, represents highly aggressive malignancies that often exhibit TP53 mutations. Certain workers hypothesize that these tumors may originate in other pelvic organs, such as the Fallopian tubes, and subsequently affect the ovaries. Endometrioid and clear cell ovarian carcinomas are believed to develop from ovarian endometriosis.
Presentation: stomach pain, tiredness, abdominal distension, and diarrhea. The ambiguous and nonspecific characteristics of the symptoms frequently lead women to attribute them to stress or menopause. Women who pursue medical care are frequently misdiagnosed with benign gastrointestinal or urinary disorders. Most women present with advanced disease at the time of diagnosis. Macroscopy The ovary is hypertrophied and substituted by a neoplastic tumor that is frequently both solid and cystic. Mucinous tumors may comprise gelatinous substances. Histopathology Serous carcinomas consist of malignant epithelial cells that proliferate in irregular branching papillae and create slit-like glandular gaps. Psammoma bodies may be observed.
Endometrioid carcinomas consist of malignant epithelial cells that create round or oval glands similar to those found in endometrial carcinomas. Regions of squamous differentiation are prevalent. Mucinous carcinomas consist of malignant epithelial cells characterized by mucinous cytoplasm that forms glandular structures. Differentiating original ovarian mucinous carcinoma from metastatic mucinous carcinoma originating in the gastrointestinal tract can be quite challenging. transparent cell carcinomas consist of malignant epithelial cells characterized by transparent cytoplasm and hobnailing, which proliferate in tiny tubules and papillae. Transitional cell carcinomas exhibit morphological similarities to urothelial carcinomas; however, their immunophenotypic characteristics align more closely with serous carcinomas.
Prognosis: Generally unfavorable, as the majority of women arrive with advanced disease (FIGO III and IV), correlating with a 5-year survival rate of 25–30% (in contrast to 80–90% for FIGO I or II).
FIGO staging of ovarian carcinomas
IA: tumour limited to one ovary; capsule intact, no tumour on the
ovarian surface; no malignant cells in ascites or peritoneal washings.

Pathology - Ovarian benign tumors
Cystic teratoma in maturity Benign germ cell ovarian tumors, sometimes referred to as "dermoid cysts," are most common in young women aged 20 to 29. • Larger tumors may cause pelvic pain, but many are asymptomatic and found by accident. Torsion or rupture, which results in an acute abdomen, is the most dangerous consequence. • The tumor appears cystic from a macroscopic perspective and contains a soft, greasy yellow substance. Teeth, bone, cartilage, and hair may be apparent. • According to histology, the tumor is made up of mature adult-type tissues of almost any kind, such as cartilage, smooth muscle, fat, skin, brain, respiratory, and gastrointestinal tissue.Although they are far less common, the majority of other germ cell ovarian tumors (such as dysgerminoma and immature teratoma) exhibit malignant behavior.
Cystadenoma serous -Benign epithelial ovarian tumors typically affect premenopausal women. They can be discovered by chance when a pelvic mass or an acute abdomen from torsion is present. They can be unilocular or multilocular in appearance. Histologically, the cysts are lined by a single layer of bland columnar cells, which may be ciliated or non-ciliated. The cysts contain clear fluid and have a thin wall with a smooth lining.
Cystomatous mucinous tumor • Premenopausal women typically develop benign epithelial ovarian tumors. • It may be discovered by chance when there are signs of a pelvic mass or an acute abdomen brought on by torsion. • On a macroscopic level, the tumor is often unilateral and measures 10 cm on average, though there have been cases of enormous tumors. One or more cysts filled with viscous mucoid material make up the tumor. • A single layer of bland columnar cells, either intestinal or endocervical in origin, lines the cysts histologically.
Ovarian Fibroma
Benign sex-cord stromal ovarian tumors, which are made of collagen and fibrocytes, can occur in a variety of age groups, although the majority are found in women over 50. They are frequently found by accident and are little. Ascites and stomach pain may result from a large tumor. • From a macroscopic perspective, the tumor has a solid white sliced surface. • According to histology, the tumor is made up of bland spindled cells that are expanding within a collagenous stroma.
Ovarian tumors that are borderline epithelial
A class of epithelial tumors known as borderline epithelial ovarian tumors tends to behave indolently yet shows more marked proliferation than benign epithelial tumors. Serous (borderline serous) tumors make up the great bulk of borderline epithelial tumors. At the macroscopic level, they are enormous, often bilateral, cystic tumors that are typically multifocal. Numerous papillary excrescences protrude from the cysts' surface. The tumors exhibit low-grade nuclear atypia and are histologically formed of complicated branching papillae covered by proliferating columnar epithelial cells. The existence of tiny tumor "implants" in the peritoneum or omentum in around 15% to 30% of cases is an odd characteristic of borderline serous tumors. These implants can be classified as either invasive or non-invasive histologically. The majority are non-invasive, and the prognosis for these patients is typically favorable. Although invasive implants are extremely uncommon, they are typically linked to a poor prognosis

Pathology – Ectopic Pregnancy
Definition: When a fertilized ovum implants abnormally outside of the uterus. Almost all of them take place in the ampullary region of the Fallopian tubes. Rarely, other locations include the abdominal cavity and ovaries.
The study of epidemiology • The incidence is 12 per 1000 pregnancies annually and is on the rise. The cause • The most frequent risk factor is tubal scarring from prior PID episodes. • Endometriosis and prior tubal surgery are additional risk factors. • Roughly half happen for no apparent reason.
The pathogenesis • There is severe bleeding into the Fallopian tube when trophoblasts are implanted there. • The tubal wall may rupture abruptly or gradually; the embryo may become dislodged and be absorbed by the wall or shed.
Presentation: • Sudden rupture results in an acute abdomen with peritonism and shock; • Typical presentation is progressively growing stomach discomfort and vaginal bleeding. 2. If a woman of reproductive age experiences stomach pain, take the diagnosis into consideration. Macroscopy • There is a noticeable dilatation and congestion of the affected Fallopian tube. • Friable material and blood fill the tubal lumen. Histopathology: The Fallopian tube contains chorionic villi and infiltrating extravillous trophoblasts.
Prognosis: If the diagnosis is made and the proper treatment is administered, the prognosis is favorable. • A increased risk of subsequent ectopic pregnancies is linked to having one ectopic pregnancy.

Pathology - Functional ovarian cysts
Definition • Ovarian follicles exhibiting pathogenic cystic alterations. • A suggested threshold distinguishing normal cystic follicles from functional cysts is 2.5 cm.
Terminology: Cysts originating from pre-ovulatory follicles are termed follicular cysts, whereas those arising from the corpus luteum are referred to as corpus luteum cysts.
Epidemiology: Highly prevalent.
Aetiology • Follicular cysts are believed to indicate dysfunction of the pituitary-ovarian axis. Corpus luteum cysts arise from severe hemorrhage within a corpus luteum.
Presentation • Nearly all are identified incidentally, either through imaging or by a surgeon examining the pelvis. • Large cysts may intermittently manifest as a pelvic mass. Macroscopy: Follicular cysts are often solitary and range in size from 2.5 to 10 cm. The structures are characterized by smooth contours and contain a transparent fluid. Corpus luteum cysts typically range in size from 2.5 to 5 cm. The cyst contains sanguineous fluid, and the wall is frequently yellow
Cytopathology . : The aspirated fluid from a follicular cyst comprises many granulosa cells characterized by spherical nuclei, coarse chromatin, and a narrow rim of cytoplasm. Nuclear grooves may be observed. Certain cysts may also comprise luteinized cells. Aspirated fluid from a corpus luteum cyst comprises blood, haemosiderin-laden macrophages, and many completely luteinized granulosa cells. These are sizable polyhedral cells characterized by copious finely granular cytoplasm. The nuclei are round to elliptical, exhibiting finely granular chromatin and conspicuous nucleoli. Nuclear grooves are absent. Histopathology Follicular cysts are composed of granulosa and theca cells, which may exhibit luteinization. Corpus luteum cysts have significant central hemorrhage. The lining consists of entirely luteinized granulosa and theca cells.
Prognosis: Functional ovarian cysts are completely benign. They are mostly of clinical significance, as big cysts may raise suspicion for a cystic neoplasm.

Aspirated fluid from a corpus luteum cyst comprises blood, haemosiderin-laden macrophages, and many completely luteinized granulosa cells. These are sizable polyhedral cells characterized by copious finely granular cytoplasm. The nuclei are round to elliptical, exhibiting finely granular chromatin and conspicuous nucleoli. Nuclear grooves are absent. Histopathology Follicular cysts are composed of granulosa and theca cells, which may exhibit luteinization. Corpus luteum cysts have significant central hemorrhage. The lining consists of entirely luteinized granulosa and theca cells.
Prognosis: Functional ovarian cysts are completely benign. They are mostly of clinical significance, as big cysts may raise suspicion for a cystic neoplasm.
