The disease has a characteristic presentation of pancytopenia, splenomegaly, and hairy cells in the circulation, marrow, and other hematopoietic organs. Hairy cells are named for their fine protrusions that look like hair. Hairy cell leukemia (HCL) is an uncommon, indolent, mature B-cell neoplasm. The lymph nodes are usually not enlarged. Seen under the microscope, the cells have delicate cytoplasmic projections, resembling hair, and that is why the disease was named HCL. The characteristic 'hairy cells', present in the peripheral blood and bone marrow, are the hallmark of this leukaemia. Hairy cell leukaemia is a rare chronic neoplastic B-cell lymphoproliferation that characteristically involves blood, bone marrow and spleen with liver, lymph node and skin less commonly involved. Types of second primary cancers influence survival in chronic lymphocytic and hairy cell leukemia patients. Before effective drugs became available for hairy cell leukemia, splenectomy was the first-line treatment for the disease. Marked splenomegaly is usually present. The median age of disease onset is 52 years, and HCL occurs three times more commonly in white than in African American individuals. An activating. The cytopenia in HCL can vary from mild to severe and may affect the production of red blood cells, platelets, mature granulocytes, and monocytes. The condition is named after these excess B cells which look 'hairy' under a microscope. Hairy cell leukemia most commonly affects the bone marrow and spleen.

In the majority of cases, they are palpable and encountered in physical examination. BRAF V600E mutation is present in nearly all cases of HCL but absent in other B-cell lymphoproliferative disorders and represents a disease-defining genetic event in HCL. Clear splenomegaly is a clue that hairy cell is in the differential, among other things as well. Prolymphocytic leukemia: Marked the elevation of the white blood cell count, with the characteristic morphology of prolymphocytes and lack of hairy cytoplasmic projections. Autoimmune manifestations or unusual manifestations can be identified, some of which can mimic multiple myeloma. Symptoms.

HCL is a rare disease accounting for only 2% of all lymphoid leukemias. Hairy-cell leukaemia (HCL) is an uncommon type of mature B-cell neoplasm with an indolent course. It's called hairy cell anemia because the abnormal cells appear hairy when viewed under a microscope. Even though hairy cell leukemia affects the white cells, the lymph nodes usually don't enlarge. B lymphocytes normally produce antibodies to help fight infections. Hairy cell leukemia is a blood cell cancer characterized by proliferation of cancerous lymphocytes, a type of white blood cell that fights infections when not cancerous. The disease is not curable. Hairy cells tend to accumulate in the bone marrow, liver and spleen. Clinically manifested by hepatosplenomegaly, lymphadenopathy, lymphocytosis with "hairy" lymphocytes, pancytopenia. Peripheral cytopenias and splenomegaly due to presence of characteristics neoplastic B lymphocytes in the blood, bone marrow, and organs of the classic reticuloendothelial system associated with reticulin-fibrosis of the marrow.

Hairy cell leukemia is an indolent leukemia with an overall 12-year survival rate of>85% [166-168]. Hairy cell leukemia: Pancytopenia and monocytopenia with characteristically few circulating cells. Hairy cell leukemia (HCL) is a cancer of the blood that starts in your bone marrow -- the soft tissue inside bones where blood cells are made. The white blood cells help fight off germs. Evaluation of Splenomegaly These findings suggest that hypocholesterolemia in HCL is related to tumor burden and not to splenomegaly alone. The morphological, IHC, flow cytometry and molecular studies pointed towards a diagnosis of hairy cell leukemia (HCL). .

Fever, night sweats, fatigue, and weight . Untreated hairy cell leukemia is characterized by splenomegaly, varying degrees of leukopenia (occasionally leukocytosis) and/or pancytopenia, and bone marrow infiltration by an atypical cell with prominent cytoplasmic projections (i.e., hairy cells). In milder forms, a liver and spleen scan or ultrasound measurement may detect mild organomegaly that could be missed by abdominal palpation. They are very useful to evaluate splenomegaly and hepatomegaly in mild forms of hairy cell leukemia. Hairy cell leukemia (HCL) is a rare lymphoid malignancy. There are a few different types of white blood cells. Hairy cell leukaemia (HCL) is a rare type of chronic leukaemia of the lymphoid system, in which abnormal B-lymphocytes accumulate in the bone marrow, liver and spleen. The two most important findings that establish a diagnosis of hairy cell leukemia are enlargement of the spleen and an unexpected decrease in normal blood cell count.

It happens when your bone marrow makes too many. Hairy cell leukemia variant is a chronic lymphoproliferative disorder whose characteristics resemble the classic form and splenic marginal zone lymphoma, making differential diagnosis essential for therapeutic follow-up, as hairy cell leukemia variant has a decreased response to drugs prescribed for the classic form. Etiology. Treatment directed at hairy cell leukemia controls splenomegaly; however, some patients may require splenectomy. This intermediate magnification view shows numerous small areas of hemorrhage (blood lakes or pseudosinuses) that are lined by hairy cells. There are reports indicating that HCL patients without splenomegaly tend to remain free from significant neutropenia, have an excellent survival rate, and are usually older than the patients with splenomegaly. Hairy cell leukemia is a rare form of leukemia, or cancer of your blood cells. Classic cases present with pancytopenias including monocytopenia. You might have pain or discomfort when you eat. There is an increased chance of splenic rupture due to trauma. Most people have symptoms arising from an enlarged spleen (such as fullness or discomfort in the abdomen) or symptoms arising from reduced blood counts (abnormal bleeding/bruising/clotting, or infection). Hairy cell Leukemia (HCL) is an indolent B cell malignancy involving spleen, peripheral blood and bone marrow. Spleen is almost always involved in hairy cell leukemia resulting in massive splenomemgaly. The disease is called hairy cell leukemia because the leukemia cells look "hairy" when viewed under a microscope. Hairy cell leukemia (HCL) is a rare indolent lymphoproliferative neoplasm of mature B cells with a distinct clinical presentation that includes peripheral blood cytopenias, splenomegaly and a small number of circulating neoplastic cells with hair-like cytoplasmic projections Essential features Pancytopenia and monocytopenia Splenomegaly Abstract Hairy cell leukemia can cause massive splenomegaly which may lead to urinary retention and constipation. In people who receive treatment, the long-term outlook for hairy cell leukemia is good. Then finally, people also present . Epidemiology and Etiology The family of HCLs are chronic B-cell malignancies that account for approximately 2% of all diagnosed leukemias. Most patients with hairy cell leukemia have massive splenomegaly, such that imaging studies are unnecessary to appreciate its presence.
