    Abstract:
    BACKGROUND: No cytologic reports on spermatic cord sarcomas have been published. CASE: A 64-year-old man presented with a slowly growing, painless, left spermatic cord enlargement. Fine needle aspiration (FNA) obtained < 1 mL of bloody fluid consisting of solitary, mark-edly anaplastic and pleomorphic tumor giant cells occasionally arranged in small fragments. Rare atypical spindle cells could be observed. Some reactive lymphocytes were observed intermingled with tumor cells. Immunohistochemistry displayed vimentin reactivity and negativity for keratins and leukocytic common antigen. The specimen removed showed a well-circumscribed, 30-mm, yellowish solid tumor. Touch imprints displayed pleomorphic tumor cells showing intense anisonucleosis; a moderate amount of clear, sometimes microvacuolated cytoplasm; and tissue fragments with a storiform pattern. Histologic examination revealed microscopic and immunohistochemical features of malignant fibrous histiocytoma (MFH) arising in soft tissues of the spermatic cord. CONCLUSION: FNA of a spermatic cord lesion may reveal a pleomorphic sarcoma. A pleomorphic appearance together with some spindle elements and compatible immunocytochemistry could help diagnose spermatic cord MFH. This is one of the few reports dealing with FNA cytology of paratesticular tumors and the first report, to the best of our knowledge, showing the cytologic characteristics of a case of spermatic cord MFH.
