title: Fine-needle aspiration cytology of sinus histiocytosis with massive lymphadenopathy: a case report.
abstract: Cytological findings of sinus histiocytosis with massive lymphadenopathy (SHML), involving bilateral cervical lymph nodes of a 12-yr-old boy, are presented here. A striking feature was the presence of large histiocytes with abundant pale cytoplasm containing well-preserved lymphocytes, plasma cells, and occasional neutrophils, scattered in a background of reactive lymphoid cells. Subsequent open biopsy of the lymph node mass confirmed the cytologic findings. Cytologic features of SHML are virtually diagnostic and can negate the need for an open biopsy in most cases.
