Fine needle aspiration biopsy diagnosis of cysticercosis. A case report.

A case of cysticercosis was initially diagnosed by fine needle aspiration biopsy (FNAB). A tender, hard mass in a muscle was clinically suspected of being a benign tumor. An FNAB smear showed many eosinophils and a part of cestode. After 10 minutes the patient felt a short-lived local hot sensation and pain. The diagnosis was confirmed on a histologic section of an incisional biopsy specimen from another site.
