Symptoms and Signs – Differential Diagnosis of Gynecomastia
Gynecomastia
In males only, gynecomastia is the condition characterised by enlarged breast size caused by Excessive proliferation of the mammary gland. This difference in breast size may be either barely detectable or readily apparent. Gynecomastia, often occurring bilaterally, can be accompanied by breast pain and involuntary milk production.
Typically, breast development is regulated by many hormones. Estrogens, growth hormone, and corticosteroids promote the development of the ducts, in contrast to progesterone and prolactin which stimulate the growth of the alveolar lobules. While the exact mechanism of gynecomastia is not completely understood, it is widely believed that a hormonal imbalance, namely a shift in the estrogen-androgen ratio and an elevation in prolactin levels, is a probable contributing element. Thus, gynecomastia often arises as a consequence of the actions of estrogens and other medications. The condition may also arise from hormone-secreting malignancies as well as from endocrine, genetic, hepatic, or adrenal dysfunctions. Normal variations in hormone levels can lead to the development of physiological gynecomastia in newborn, pubertal, and geriatric males.
Histories and Physical Assessment
Start the medical history by inquiring about the patient's initial observation of his breast growth. What was his age at that time? Since then, have his breasts undergone increasing enlargement, reduction, or remained unchanged? Is there concomitant breast discomfort or discharge? Obtain his description of the discharge, if present. Inquire whether he has ever undergone nipple piercing. If that is the case, were there any ensuing problems resulting from the piercings? Furthermore, obtain a comprehensive drug history encompassing prescription, over the counter, herbal, and street medications. Proceed to investigate related indications and manifestations, such as the presence of a testicular mass or pain, diminished libido, reduced potency, and the absence of hair in the chest, axillary tract, or face.
Center the physical examination specifically on the breasts, testicles, and penis. During the examination of the breasts, give attention to any asymmetry, dimpling, aberrant pigmentation, or ulceration. Examine the testicles as to their dimensions and equality. Next, examine them by palpation to identify any nodules, discomfort, or atypical consistency. Examine the pattern of penile growth following puberty and take note of any hypospadias.
Medical etiology
Adrenal neoplasm.
Estrogen synthesis by an adrenal tumour can lead to a feminising condition in males marked by bilateral gynecomastia, diminished libido, impotence, testicular atrophy, and decreased facial hair growth. In addition, cushingoid features such as moon face and purple striae may manifest.
Mammary cancer
Sudden onset of painful unilateral gynecomastia is observed in males diagnosed with breast cancer. A palpable breast lump that is hard or stony may indicate the presence of a malignant tumor. Additional findings from a breast examination include alterations in breast symmetry, skin abnormalities such as thickness, dimpling, peau d'orange, or ulceration, a warm, flushed area, and nipple abnormalities such as itching, burning, erosion, deviation, flattening, retraction, and a watery, bloody, or purulent discharge.
Primary hyperthyroidism. Gynecomastia can arise from aberrations in the delicate equilibrium of estrogen and testosterone levels. Hyperthyroidism is the condition characterized by excessive production of thyroxine by the thyroid gland. Additional symptoms include abrupt decline in body weight, tachycardia, anxiety, hypersensitivity to heat, insomnia, muscular weakness, and exhaustion.
Klinefelter's syndrome
In Klinefelter's syndrome, a hereditary condition, painless bilateral gynecomastia initially manifests throughout adolescence. Prior to puberty, symptoms encompass atypically diminutive testicles and a minor cognitive impairment; post-puberty, scant facial hair, a stunted penis, reduced libido, and impotence.
Liver cancer
Bilateral gynecomastia and other features of feminization, including testicular atrophy, impotence, and diminished facial hair growth, may be caused by liver cancer. The patient may present with intense epigastric or right upper quadrant discomfort accompanied by a mass in the right upper quadrant. In addition, a sizable tumor may generate a bruit during auscultation. Potential additional symptoms may include loss of appetite, loss of body weight, swelling of the ankles, high body temperature, shortness of breath, and maybe, jaundice or ascites.
Pituitary tumor
A pituitary tumor is a malignancy that produces hormones which leads to bilateral gynecomastia, along with galactorrhea, impotence, and reduced libido. Additional hormonal effects may encompass edema of the hands and feet, coarse facial characteristics accompanied by prognathism, deepening of the voice, weight gain, elevated blood pressure, excessive sweating, intolerance to heat, excessive pigmentation, and thicker, waxy skin. Impaired sensation and muscular weakness can impact the extremities. Proliferation of the tumor can result in visual impairment, diplopia, headache, or partial bitemporal hemianopia, which can ultimately lead to blindness.
Reifenstein's syndrome
Reifenstein’s syndrome is a hereditary condition characterised by the development of painless bilateral gynecomastia during puberty. Signs commonly associated with this condition may include hypospadias, testicular atrophy, and an undeveloped penis.
Other Factors Substance Abuse. Pharmacologically induced gynecomastia is usually characterized by pain and
I unilateral. Administering estrogens such as diethylstilbestrol, estramustine, and chlorotrianisene directly modulates the estrogen-androgen ratio in the treatment of prostate cancer. Pharmacological substances with estrogenic properties, such as cardiac glycosides and human chorionic gonadotropin, may have a similar effect. Chronic consumption of alcohol, marijuana, or heroin decreases the levels of testosterone in the bloodstream, leading to the development of gynecomastia. Additional medications, including flutamide, cyproterone, spironolactone, cimetidine, and ketoconazole, induce this clinical manifestation by disrupting androgen synthesis or activity. Certain widely used medications, such as phenothiazines, tricyclic antidepressants, and antihypertensives, induce gynecomastia through an unidentified mechanism.
Therapeutic interventions. The onset of gynecomastia might occur shortly after initiating hemodialysis for chronic renal failure. In addition, it can occur after significant surgical procedures or testicular irradiation.
Points of Special Consideration
Application of cold compresses to the patient's breasts and administration of analgesics are recommended to maximize comfort. Prepare him for diagnostic examinations, such as chest and skull radiographs and measurement of blood hormone levels.
Due to the potential impact of gynecomastia on the patient's body image, it is important to offer emotional support. Provide the patient with reassurance that treatment can effectively decrease gynecomastia. Tamoxifen, an antiestrogen, and testolactone, an inhibitor of testosterone-to-estrogen conversion, are effective in treating some cancer patients. Surgical excision of breast tissue may be used as a last resort if pharmacological therapy is ineffective.

Guidelines for Pediatric Populations
Gynecomastia in neonates may occasionally be accompanied by galactorrhea, also known as "witch's milk". This symptom often resolves within a few weeks but can endure until the age of 2.
The majority of boys experience physiological gynecomastia at some point throughout adolescence, often around the age of 14. Asymmetrical and sensitive, this gynecomastia often disappears within 2 years and seldom continues beyond the age of 20.
