Penile shaft lesion in reactional borderline tuberculoid leprosy: a case report.

A twenty-year-old man with borderline tuberculoid leprosy with lesion on the penile shaft is reported. The lesion was detected when the patient developed an upgrading reaction after MDT. The diagnosis was confirmed by histopathology. Leprosy lesions are uncommonly reported on the penis and interestingly, some seem to have been detected during reactional episodes only. It appears that like facial lesions, genital patches may also be more prone to develop a type 1 reaction.
