Penis tuberculides: papulonecrotic tuberculides on the glans penis.

Two cases of penis tuberculides are described. Although this disease once used to be comparatively common in Japan, the number of people affected by the disease has recently decreased as the prevalence of tuberculosis has fallen. However, we can still find a few cases in the Japanese literature every year. Outside Japan, we can hardly find reports of this disease, except for a few cases reported under the title of 'Papulonecrotic tuberculides on the penis' from Northern European countries. In addition to reporting 2 cases, we summarize clinical features of this disease. Racial predisposition or endemic factors may be related to the tuberculides in such a special site.
