Diagnosis of isolated tuberculous orchitis by fine-needle aspiration cytology.

An isolated tuberculous Orchitis without epididymal involvement is rare. This case report describes an extra pulmonary tuberculosis with exclusively testicular presentation. The confirmatory diagnosis of which was made on FNAC of the testis. A 22-year-old adult presented with unilateral testicular enlargement and scrotal ulcer on the same side. FNAC was performed and subsequent smear examination revealed epitheloid granuloma in a necrotic background. This was suggestive of tubercular orchitis, which was further confirmed by demonstration of very occasional acid fast bacilli in the smear. Isolated tuberculous orchitis is a rare entity; FNAC is a useful first choice of investigation. It provides a successful diagnosis thereby preventing unnecessary orchidectomy.
