Granuloma Annulare of the Penis: A Uncommon Location for an Usual Disease

Abstract

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.

Subcutaneous Granuloma Annulare of the Penis Associated with a Urethral Anomaly: Case Report and Review of the Literature

“…The subcutaneous form is rare and most commonly affects the skin of bony prominences, especially the anterior tibia, feet, hands, and occipital scalp of children younger than 5 . GA of the penis is rare, with only 15 cases previously reported in the English medical literature, 10 of which were classified as subcutaneous GA .…”

A case of granuloma annulare mimicking tinea cruris

“…Granuloma annulare lesions are typically located on the lateral or dorsal surfaces of the hands and feet, arms, thighs, and trunk [1][2][3]. Although cases of GA presenting in unusual sites have been documented in the literature, reports of GA initially presenting as lesions isolated to the bilateral inguinal folds have not been well documented [2,[4][5][6]. We present a case of a patient with GA, localized to the inguinal folds, mimicking tinea cruris.…”

Necrobiotic granuloma annulare of the penis: a case responding to anti‐tuberculosis therapy with a review of the literature

“…Granuloma annulare is an inflammatory dermatosis characterized by dermal palisading granulomas with central collagen degeneration that usually presents on areas of trauma. Penile involvement is rare [1][2][3][4][5][6] (Table 1). Clinically, GA of the penis occurs as single/multiple firm and skin-coloured subcutaneous nodules without genitourinary symptoms.…”
