Pathology - Non-Hodgkin lymphoma
Chromosomal translocations are genetic abnormalities that occur in some types of lymphomas. In Burkitt lymphoma, a specific translocation called t(8;14) leads to the overexpression of the c-myc gene. In follicular lymphoma, another translocation called t(14;18) causes the activation of the bcl-2 gene, which is the most commonly observed translocation in this type of lymphoma.
Viral infections: HIV and EBV (EBV is related with Burkitt lymphoma of the jaw).
The median age of diagnosis is 65, and it is more prevalent among males.
Study of diseases and their effects on the body
Lymph node: (1) Follicular: characterized by the proliferation of cleaved cells in a nodular pattern; (2) Burkitt: exhibits a starry-sky appearance and consists of non-cleaved cells; (3) Small lymphocytic: shows the widespread effacement of lymph node architecture by small mature lymphocytes, often associated with chronic lymphocytic leukemia (also positive for CD5 marker); (4) Diffuse large B cell: characterized by the presence of large cells with large, round nuclei; (5) Other variants include mantle cell. A marginal cell. MALT lymphoma
Presenting Symptoms
The patient presents with hepatosplenomegaly, painless lymphadenopathy, and fewer B symptoms compared to Hodgkin lymphoma.
Laboratory results indicate elevated levels of LDH, which can be utilized as a prognostic marker. Absence of hypergammaglobulinemia
Therapy
Treatment options for relapsing disease include chemotherapy, radiation therapy, and bone marrow transplant.
The median survival rate is 6-8 years. The prognosis is particularly unfavorable for elderly individuals, those with disseminated disease, and those with aggressive types.
Non-Hodgkin lymphoma (NHL) does not spread in a continuous manner.
EBV infection is additionally linked to an elevated susceptibility for nasopharyngeal cancer.

Pathology - Multiple Myeloma
A tumor cell originates from the rapid growth of a single type of plasma cells, known as monoclonal plasma cells, that are responsible for producing immunoglobulin G (IgG).
Most prevalent among individuals over the age of 60.
Pathology
Bone marrow: Malignant plasma cells with a characteristic fried-egg look originating from B lymphocytes.
Peripheral blood smear reveals the presence of erythrocytes arranged in a structure known as rouleaux.
Long bones: Lytic lesions are caused by the secretion of osteoclast-activating factor by cancerous cells.
Clinical Presentations
Primary amyloidosis is characterized by bone discomfort, fractures, renal failure, and recurrent infections.
Imaging: Visible lytic lesions on radiography
Laboratory results: The patient exhibits a monoclonal immunoglobulin spike (M protein) on serum protein electrophoresis, Bence-Jones protein (IgG light chains) in urine, anemia, elevated erythrocyte sedimentation rate (ESR), and hypercalcemia. Increased levels of immunoglobulin G (IgG) in the blood, together with elevated levels of nitrogenous waste products (azotemia).
Treatment options for patients include chemotherapy, autologous stem cell transplant, and bisphosphonates for those with hypercalcemia.
MGUS is a condition without symptoms that is defined by the presence of a monoclonal M protein spike that is less than 3 g/dL. It is not accompanied by Bence-Jones proteinuria, lytic bone lesions, or renal insufficiency. Close monitoring of patients with MGUS is important due to their heightened susceptibility to developing multiple myeloma or another lymphoproliferative illness.

Pathology - Idiopathic and Thrombotic Thrombocytopenic Purpura
Idiopathic thrombocytopenic purpura (ITP) is a condition where platelets are coated with antiplatelet IgG antibodies, causing them to be engulfed by macrophages in the spleen. May be linked to autoimmune disorders.
The individual is affected by either HIV infection or lymphoproliferative diseases. Manifests in pediatric patients as a transient and restricted response to viral infection. Alternatively, it might manifest in adulthood as a persistent condition.
The etiology of thrombotic thrombocytopenic purpura (TTP) is currently unknown, however viral infection (such as HIV), medications, and autoimmune illnesses have been suggested as potential causes. Has been associated with the acquired inhibitor of vWF-cleaving protease.Most commonly observed in women aged 20-50.
Study of the nature and causes of diseases.
ITP: Bone marrow may exhibit sporadic elevation of megakaryocytes. The examination of the blood sample reveals a condition called thrombocytopenia, characterized by a low platelet count. Additionally, the platelets appear to be slightly larger than normal.
TTP: Prevalent hyaline microthrombi present in the microvasculature without any signs of inflammation;
Peripheral blood smear reveals a low platelet count (thrombocytopenia), fragmented red blood cells (schistocytes), and an increased number of immature red blood cells (reticulocytosis).
Symptoms and signs
Initial presentation: Bleeding from the mucous membranes; nosebleeds; small red or purple spots on the skin; absence of an enlarged spleen. Laboratory results indicate a reduction in platelet count, presence of antiplatelet antibodies, and an increase in bleeding time.
TTP presents with neurologic impairments, fever, renal failure, petechia, and microangiopathic hemolytic anemia. Laboratory results indicate a drop in platelets, an increase in LDH and indirect bilirubin levels, azotemia, a decrease in the activity of vWF-cleaving protease inhibitor (ADAMTS13), an increased bleeding time, and a decrease in hematocrit (Hct).
Treatment for ITP includes the use of Prednisone, intravenous immune globulin, and splenectomy.
TTP treatment options include plasmapheresis, splenectomy, or the use of immunosuppressive medications for severe instances.

Pathology - Hemophilias A and B
Hemophilias A and B are genetic disorders characterized by a deficiency in clotting factors VIII and IX, respectively.
Hemophilia A is an X-linked recessive condition characterized by a lack of factor VIII.
Hemophilia B is a genetic condition that is inherited in an X-linked recessive manner, leading to a shortage of factor IX in the blood.
Study of the nature and causes of diseases.
Insufficiency of clotting factor VIII or IX leads to an inefficient intrinsic pathway of blood clotting.
Symptoms and signs
Hemorrhaging into muscular tissues and joints (hemarthrosis); effortless formation of bruises; gastrointestinal bleeding.
Laboratory results: Extended partial thromboplastin time (PTT), within normal range prothrombin time (PT), normal bleeding time, normal thrombin time
Therapy
Administer a clotting factor to compensate for the deficiency.
The primary causes of vitamin K shortage include liver illness, malabsorption, or the administration of warfarin. The condition leads to a lack of factors II, VII, IX, and X, and laboratory tests show an extended prothrombin time (PT).

Pathology - Chronic Lymphocytic Leukemia
Chronic Lymphocytic Leukemia is a type of cancer that affects the white blood cells.
Linked to genetic disorders involving an extra copy of chromosome 12, deletions of chromosome 13g, and deletions of chromosome 11q. Typically manifests gradually in males over the age of 60.
Pathology
Bone marrow: Infiltration by tiny lymphocytic cells that resemble mature B lymphocytes (they express CD5, a marker typically found in T lymphocytes).
Peripheral blood smear: Smudge cells (leukemic cells are susceptible to mechanical disruption)
During the process of slide preparation, there is an occurrence of lymphocytosis, which is characterized by the presence of a normal amount of lymphocytes. Additionally, the lymphocytes appear to have normal coloration. Erythrocytes with normal size
Symptoms and signs
Manifestations may include lymphadenopathy, hepatosplenomegaly, mucosal bleeding, and exhaustion. However, it is important to note that some patients may experience little symptoms, indicating a slow and chronic progression of the condition.
Complications encompass the occurrence of elevated AlHA levels, thrombocytopenia, and hypogammaglobulinemia, all of which contribute to the development of infections.
Therapy
Chemotherapy is administered to alleviate symptoms or in patients experiencing end-organ failure, although achieving a cure is uncommon.
The average lifespan following diagnosis ranges from 3 to 25 years, depending on the cytogenetic status. Poorer survival outcomes are associated with the presence of markers such as ZAP 70, CD 38, and del 17p.

Down syndrome and exposure to ionizing radiation, benzene, and chemotherapy are considered risk factors.
Study of the nature and causes of diseases.
Linked to chromosomal translocations are M3-t(15;17) and M2-t(8:21).
Most commonly observed in individuals in their middle adulthood.
There exist eight subgroups (MO-M7), each linked to a distinct neoplastic myeloid lineage (myelocyte, monocyte, megakaryocyte, erythrocyte) and a particular stage of development.
Medullary tissue within the cavities of bones: The tissue exhibits a high density of cells with abnormal structure; the myeloblasts are unique to this particular subtype; Auer rods, which are granules in the cytoplasm, are particularly prevalent in M3 (acute promyelocytic leukemia).
Peripheral blood smear reveals pancytopenia accompanied by the presence of myeloblasts.
Symptoms and signs
The individual may experience symptoms such as tiredness, infection, excessive bleeding (including heavy menstrual bleeding and nosebleeds), swelling of the lymph nodes, enlargement of the liver and spleen, and stroke resulting from the blockage of small blood vessels due to a high number of immature white blood cells.
Therapy
Treatment options for the condition include chemotherapy, bone marrow transplant, and the use of all-trans retinoic acid specifically for cases with the (15;17) translocation in M3 subtype.
The prognosis is moderately positive, with a 60% chance of achieving remission. However, only 25% of these individuals manage to remain free of the disease for a period of 5 years.

Dermatology - Impetigo
The primary causative agents of impetigo are Staphylococcus aureus and beta-hemolytic streptococcus group A. Bullous impetigo occurs due to the localized synthesis of epidermolytic toxin by Staphylococcus aureus bacteria. These microorganisms are not commonly found in the normal human skin microbiota, but instead temporarily inhabit the skin and can lead to surface-level diseases. Primary infections are most prevalent in youngsters, however both primary and secondary infections can occur in individuals of all age groups.
Superficial infections frequently lack noticeable symptoms.
Impetigo manifests as erosions characterized by golden-yellow crusts of 1 to 3 cm in diameter. These lesions exhibit central healing after several weeks of presence. The lesions are spread out, separate, and might merge together; satellite lesions form by self-infection. Secondary infection is frequently observed. Bullous impetigo is characterized by the presence of blisters filled with clear yellow or slightly cloudy fluid, surrounded by a red ring, on skin that appears normal. Rupture leads to the decompression of bullous lesions. Removing the roof of a bulla results in the formation of shallow and wet erosion. Ecthyma is characterized by the presence of ulceration accompanied by a thick crust that adheres firmly to the skin. This condition may cause tenderness and hardening of the affected area.
The diagnosis is made based on clinical observations and validated through laboratory culture testing. The differential diagnosis comprises excoriation, allergic contact dermatitis, herpes simplex, epidermal dermatophytosis, scabies, burns, porphyria cutanea tarda, venous stasis, and ischemic ulcers.
Manage lesions by applying mupirocin and retapamulin ointment, and prevent them from happening again by using benzoyl peroxide wash and/or applying mupirocin and retapamulin ointment to the nostrils.
Examine family members for symptoms of impetigo and urge all those in close proximity to cleanse their hands with ethanol or isopropyl gel. Treatment using antibiotics that act throughout the body.
