Extranodal NK/T‐cell lymphoma, nasal type, is a predominantly extranodal lymphoma characterized histologically by prominent necrosis, angiocentric growth, and vascular destruction. Only one report describing its fine‐needle aspiration (FNA) cytologic features is available and shows highly unusual findings for a lymphoma. The present case concerns a 58‐yr‐old patient that presented with a soft tissue mass of the thigh in addition to an ulcerative lesion of the palate and nodular hepatic and splenic lesions. FNA cytology of the thigh tumor was interpreted as a malignant mesenchymal lesion (sarcoma). The subsequent pathologic study revealed an NK/T‐cell lymphoma. Our findings are very similar to those previously reported. They were highly unusual for a lymphoma and consisted of polymorphic, round to spindle neoplastic cells distributed in irregular aggregates, and single cells. No significant number of lymphoglandular bodies were present. Diagn. Cytopathol. 2002;27:371–374. © 2002 Wiley‐Liss, Inc.
