[Morphological diagnosis of Lennert lymphoma]

Two observations of Lennert lymphoma are described. The cytological and histological diagnosis of the disease was established after examination of cervical and axillary lymph nodes on the basis of combination of the following features: multiple tubercle-like aggregates of epithelioid cells and large atypical histiocytes, marked malignant transformation of both large and small lymphoid cells, infiltration of the lymph node capsule and extranodal tissue with atypical lymphocytes and histiocytes, the absence of Berezovsky-Sternberg cells.
