Study Notes
Hematology
- Hematology is the study of blood and blood-forming tissues.
- Lymphomas are a group of cancers arising from lymphocytes.
- Lymphomas are divided into Hodgkin lymphoma and Non-Hodgkin lymphoma (NHL).
- Hodgkin lymphoma is characterized by the presence of Reed-Sternberg cells.
- NHL encompasses a diverse group of lymphomas that lack the characteristic Reed-Sternberg cells.
Hodgkin's Lymphoma
- Hodgkin lymphoma exhibits Reed-Sternberg (RS) cells.
- RS cells are large, and typically binucleated/bilobed with large inclusions like owl's eyes within the nucleus.
- Cytoplasm is abundant and weakly eosinophilic.
- Hodgkin lymphoma often arises in a single node or chain of nodes and spreads contiguously to adjacent lymph nodes.
- Clinically, most patients present painless, non-tender, asymmetrical, firm, discrete, and rubbery enlargement of superficial lymph nodes.
- Constitutional symptoms like fever, profuse sweating, weight loss, and pruritus are more prominent in patients with widespread disease.
Hodgkin's Lymphoma Subtypes
- Nodular sclerosis (NS) is characterized by collagen bands and lacunar cells.
- Mixed cellularity (MC) displays a mixed infiltrate with classic Reed-Sternberg cells.
- Lymphocyte-rich (LR) subtype features lymphocyte dominance with few Reed-Sternberg cells.
- Lymphocyte-depleted (LD) shows few lymphocytes and abundant Reed-Sternberg cells.
Non-Hodgkin Lymphoma (NHL)
- NHL features diverse types, including Burkitt's and Diffuse Large B Cell lymphoma.
- Burkitt's lymphoma is characterized by a high mitotic rate and medium-sized cells with clumped chromatin; often presents with a starry sky appearance.
- Diffuse large B-cell lymphoma displays large cells with open chromatin, prominent nucleoli, and a round, irregular, or cleaved nucleus.
Reactive Hyperplasia
- Reactive hyperplasia is a non-neoplastic increase in the number of cells in a tissue or organ in response to a stimulus.
- Follicular type involves reactive lymphoid hyperplasia with larger lymphocytes in germinal centers.
Myeloproliferative Neoplasms (MPNs)
- MPNs are a group of blood-forming cell disorders involving clonal expansion of one or more blood cell lineages.
- Classified into Polycythemia Vera (PV), Essential Thrombocythemia (ET), and Myelofibrosis (MF).
Polycythemia Vera (PV)
- PV is characterized by an increase in red blood cell mass, potentially leading to high blood viscosity and circulatory issues.
- Often presents with symptoms such as hepatosplenomegaly and erythromelalgia.
- Diagnostic features include elevated hemoglobin and hematocrit levels, along with low serum erythropoietin levels, often in the presence of high red blood cell count (RBC).
Essential Thrombocythemia (ET)
- ET is characterized by elevated platelet counts above normal.
- Potential complications include thrombotic and hemorrhagic events, and splenomegaly.
Myelofibrosis (MF)
- MF is characterized by bone marrow fibrosis, and the development of hematopoiesis in the spleen and liver.
- Diagnostic features include a peripheral blood film showing leucoerythroblastic change with "tear-drop" cells and bone marrow showing fibrosis.
