Other malignant neoplasms of lymphoid and histiocytic tissue
Nodular lymphoma
- A neoplasm of follicle centre B cells which has at least a partial follicular pattern. Follicular lymphomas comprise about 35% of adult non-Hodgkin lymphomas in the U.S. and 22% worldwide. Most patients have widespread disease at diagnosis. Morphologically, follicular lymphomas are classified as Grade 1, Grade 2, and Grade 3, depending on the percentage of the large lymphocytes present. The vast majority of cases (70-95%) express the BCL-2 rearrangement [t(14;18)]. Histological grade correlates with prognosis. Grades 1 and 2 follicular lymphomas are indolent and grade 3 is more aggressive (adapted from WHO, 2001).

Mycosis fungoides
- (mye-KO-sis fun-GOY-deez) A type of non-Hodgkin's lymphoma that first appears on the skin and can spread to the lymph nodes or other organs such as the spleen, liver, or lungs.
- chronic malignant T-cell lymphoma of the skin; in the late stages the lymph nodes and viscera are affected.
- A peripheral (mature) T-cell lymphoma presenting in the skin with patches/plaques. It is characterized by epidermal and dermal infiltration of small to medium-sized T-cells with cerebriform nuclei. Patients with limited disease generally have an excellent prognosis. In the more advanced stages, the prognosis is poor. (WHO, 2001)

Leukemic reticuloendotheliosis
- neoplastic disease of the lymphoreticular cells which is considered to be a rare type of chronic leukemia; it is characterized by an insidious onset, splenomegaly, anemia, granulocytopenia, thrombocytopenia, little or no lymphadenopathy, and the presence of hairy or flagellated cells in the blood and bone marrow.
- A type of chronic leukemia in which the abnormal white blood cells appear to be covered with tiny hairs when viewed under a microscope.
- A rare neoplasm of small B-lymphocytes with "hairy" projections in bone marrow, spleen, and peripheral blood. Most patients are middle-aged to elderly adults and present with splenomegaly and pancytopenia. (WHO, 2001)

Letterer-siwe disease
- A multifocal, multisystem form of Langerhans-cell histiocytosis. There is involvement of multiple organ systems including the bones, skin, liver, spleen, and lymph nodes. Patients are usually infants presenting with fever, hepatosplenomegaly, lymphadenopathy, bone and skin lesions, and pancytopenia.

- A variant of mastocytosis characterized by multifocal, dense infiltrates of mast cells (15 or more mast cells in aggregates) detected in the bone marrow and/or other extracutaneous sites. (WHO, 2001) -- 2003

Peripheral t-cell lymphoma
- This type of lymphoma is not frequently seen in the western hemisphere. Clinically, with the exception of anaplastic large cell lymphoma, mature T- and NK-cell lymphomas are among the most aggressive of all hematopoietic neoplasms. Representative disease entities include mycosis fungoides, angioimmunoblastic T-cell lymphoma, hepatosplenic T-cell lymphoma, and anaplastic large cell lymphoma.
Other malignant lymphomas
- malignant (clonal) proliferation of B- or T- lymphocytes which involves the lymph nodes, bone marrow and/or extranodal sites; general term for various neoplastic diseases of the lymphoid tissue.
- (lim-FO-ma) Cancer that arises in cells of the lymphatic system.
- A malignant (clonal) proliferation of B- lymphocytes or T- lymphocytes which involves the lymph nodes, bone marrow and/or extranodal sites. This category includes Non-Hodgkin lymphomas and Hodgkin lymphomas.
- malignant lymphoma in which neoplastic cells diffusely infiltrate the entire lymph node without any definite organized pattern; patients whose lymphomas present a diffuse pattern generally have a more unfavorable survival outlook than those presenting with a follicular or nodular pattern.
- An obsolete term for a malignant tumor of lymphatic tissue.
