Abstract

Tuberculosis of the penis is rare. The clinical features of penile tuberculosis are usually manifested as ulceration or scars. However, the authors encountered a case of penile tuberculosis that presented as a mass. A painless nodule at the base of the penis was noted in a 63-year-old male patient. Surgical excision was recommended, and pathologic finding revealed granulomatous inflammation in the mass. Acid fast bacilli stain and culture were negative, but a positive result was found in urine polymerase chain reaction for detection of Mycobacterium tuberculosis. He was diagnosed with tuberculosis of the penis and underwent anti-tuberculosis chemotherapy.

  Fig. 1. Abdomino-pelvic computed tomography showed a 15×15×17 mm sized non-enhancing cystic mass with wall enhancement on the dorsal aspect of the penis base (arrow).

• 

  Fig. 2. Penile ultrasonography showed a 15×8×17 mm sized heterogeneous hypoechoic mass with irregular wall thickening in the penile base.

• 

  Fig. 3. Multiple diverticulums in the vicinity of the ejaculatory duct (arrow) were observed on verumontanum intraoperative cystoscopy.

  Fig. 4. Histologically, well circumscribed nodules contain chronic granulomatous inflammation with caseous necrosis (arrows) (H&E stain, ×400).
