Subcutaneous or deep granuloma annulare is a benign asymptomatic condition characterized by firm asymptomatic nodules in deep subcutaneous tissues that may be associated with intradermal lesions. A 53-year-old female presented with asymptomatic skin-colored, firm nodules over the right ring finger. Histopathology revealed a palisading granuloma with central degenerated collagen and mucin deposition in the dermis suggestive of granuloma annulare. Isolated and unilateral involvement of a single digit with clusters of nodules of subcutaneous granuloma annulare (GA) in an adult is rare and differentiation from its simulator rheumatoid nodule is essential.
皮下或深部环状肉芽肿是一种良性无症状疾病，其特征为深部皮下组织出现坚实的无症状结节，可能与真皮内病变相关。一名53岁女性患者右手环指出现无症状的肤色坚实结节。组织病理学显示为栅栏状肉芽肿，真皮内有中央变性胶原和粘蛋白沉积，提示环状肉芽肿。成人单个手指孤立且单侧受累，出现皮下环状肉芽肿（GA）结节簇的情况罕见，与类似疾病类风湿结节进行鉴别至关重要。
