Abstract

Cytologic features of a case of mantle cell lymphoma is presented, which was obtained by fine needle aspiration cytoloby and confirmed by excisional biopsy of axillary lymph node. A 67-year-old female alleged palpable masses in both axillae for several months. Additional multiple lymphadenopathies were found in the both neck and inguinal areas. The main cytologic feature was carpeting of monotonous slightly atypical small lymphocytes without heterogeneous components. The nuclei of these lymphocytes are slightly larger than benign small lymphocyte and relatively round with some indentation. Nucleolus was not prominent and no mitosis was found. Their cytoplasm was scanty and cyanophilic in Papanicolaou's stain. The histiocytic cells, which had bland-looking banded nuclei and abundant cytoplasm, corresponding to pink histiocytes were shown. Excisional biopsy of lymph nodes was diagnosed as mantle cell lymphoma, diffuse type.
