Subcutaneous granuloma annulare (SGA) is an uncommon subtype of granuloma annulare. There are few reports of this entity solely affecting the scalp. We report a case of biopsy-proven SGA in a 21-month-old boy with six asymptomatic, rock-hard scalp nodules.
皮下环状肉芽肿（SGA）是环状肉芽肿的一种罕见亚型。关于该病症仅累及头皮的报道很少。我们报告一例经活检证实的SGA病例，患者为一名21个月大的男孩，头皮有六个无症状、质地坚硬的结节。
