Abstract

Subcutaneous granuloma annulare (GA) is a rare but self-limiting inflammatory disorder of skin that occurs over the scalp, shins or dorsal surface of the hands and feet. The lesions typically present in children aged 3-6 years. A biopsy of the skin lesion is often required for definitive diagnosis. Most lesions show spontaneous resolution but the recurrence rate is high. Due to the rarity of the disease, no single treatment has been proved to be efficacious in promoting resolution or preventing recurrence. Nevertheless, the outcome is good. We described a case of 4-year-old girl presenting with asymptomatic lesions over the dorsal foot with skin biopsy-proven subcutaneous GA and a good response to topical corticosteroid.

皮下環狀肉芽腫是一種罕見的自限性炎症皮膚病,常發於頭皮、小腿或手腳背部。三至六歲的小孩為典型的發病年齡群組。診斷通常都要經由皮損的活組織檢查來確定。大多數的皮損都會自行消退,但復發率高。由於此病甚為罕見,現仍沒有任何一種治療被證實能有效加快皮損消退或預防復發。然而,患者的病情多有良好的結果。我們描述了一個四歲女孩在足背呈現無症狀的病灶,經皮膚活檢確診是皮下環狀肉芽腫,在使用外用皮質類固醇後情況得到改善。
