Granuloma annulare of the penis: a uncommon location for an usual disease.
The subcutaneous clinical variant of granuloma annulare (GA) is rare and tends to present more frequently in children, in locations unusual for conventional GA. Involvement of the penis is exceptional and has been rarely reported. Most cases are located in the shaft of the penis and tend to persist without spontaneous remission. Diagnosis is done only after biopsy, and surgical resection of the lesions is not unusual. We report a new case of subcutaneous GA of the penis in a 13-year-old boy with lesions persistent for the past year. Surgical excision of one of them allowed the correct diagnosis. No further treatment was done, and the condition has not remitted 1 year later. We stress the importance of clinical recognition of unusual presentations of GA to avoid overtreatment of lesions that do not need an aggressive approach.
