Tuberculid of the penis with a scab on the nodule.

Tuberculids of the penis are extremely rare. The clinical features of tuberculids of the penis have been reported as ulceration or scars. We have experienced a case of tuberculid of the penis that appeared as a scab on nodule. A 56-year-old man presented with a 4-month history of a painless subcutaneous nodule at the glans penis. Pathological findings of the nodule showed granulomatous inflammation. Tuberculin tests were strongly positive, but tubercle bacilli could not be detected. The diagnosis was tuberculid of the penis and the patient received antituberculosis chemotherapy. The present paper reports an interesting and rare case of tuberculid of the penis with a scab on nodule.
