title: [Differential diagnosis of B-cell lymphoma rich in T cells and peripheral T-cell lymphomas].
abstract: Clinicomorphological analysis of T-cell-rich B-cell lymphoma in a 50-year-old female and literature data revealed objective difficulties in morphological diagnosis using cytological and histological methods. Large number of epithelioid histiocytes and tumor cells polymorphism resembled Lennert's lymphoma (peripheral T-cell lymphoma). Immunohistochemical study confirmed B-cell origin of tumor cells and large number of reactive T-cells. It is suggested that it would be more correctly to use the term "Lennert-like areas" in such cases with subsequent immunohistochemical study.
