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