Monocytoid B cell lymphoma.
The clinical, light microscopic, ultrastructural, immunocytochemical and cytogenetic features of a case of monocytoid B cell lymphoma were investigated. The tumour initially affected the cervical and supraclavicular nodes, but 33 months later affected the left parotid salivary gland. The patient had subclinical Sjögren's syndrome. The neoplastic cells showed characteristic morphological feature...
متن کاملMyelo-monocytoid immunophenotypes of B-cell chronic lymphocytic leukemia cells.
Leukemia cells from ten patients with B-cell chronic lymphocytic leukemia (B-CLL) and one with B-CLL of mixed cell type (B-CLL/PL) were analyzed to delineate the cellular characteristics, especially the myelomonocytic nature. Most of the surface phenotypes were consistent with the previous reports. However, the frequency of positivity for CD22 and CD25 was much higher in the examined cases of B...
متن کاملT-bet-positive and IRTA1-positive monocytoid B cells differ from marginal zone B cells and epithelial-associated B cells in their antigen profile and topographical distribution.
BACKGROUND AND OBJECTIVES It remains controversial whether splenic and nodal marginal zone B cells, monocytoid -, and epithelial-associated B cells represent separate B-cell subsets or just variants of the same population. To clarify this issue we studied the antigen profile and topographical distribution of these cell types. DESIGN AND METHODS We studied samples of toxoplasmic lymphadenopath...

Infact, MBCL was described as the provisional nodal subty...
متن کاملMonocytoid B-cell lymphoma: its evolution and relationship to other low-grade B-cell neoplasms.
Monocytoid B-cell lymphoma (MBCL) is a newly recognized B-cell neoplasm of uncertain histogenesis. The cytologic features of the neoplastic monocytoid B lymphocytes are virtually identical to those of hairy cell leukemia (HCL). As with HCL, progression of MBCL to a higher histologic grade is very unusual. However, whereas circulating leukemic cells are a characteristic feature of HCL, periphera...
