Genital granuloma annulare of scrotum and penis with localized hand lesion : A rare presentation

Granuloma annulare (GA) is a common chronic inflammatory condition of the dermis or subcutis of unknown etiology characterized histopathologically by collagen degeneration surrounded by palisading granulomas with mucin predominantly seen on the hands and feet in females. Penile GA is rare with only 15 cases reported so far. We report here a case of genital GA with many unusual features such as the presence of dermal nodules and typical annular plaque lesions involving the scrotum as well as the shaft of the penis along with a classical lesion on the hand in a 29-year-old Asian heterosexual male with no apparent precipitating factors.
