Granuloma annulare is a benign and self-limited cutaneous disease. Subcutaneous granuloma annulare is an uncommon variant seen almost exclusively in young children, characterized by firm nodules appearing more frequently in lower extremities, buttocks, hands and scalp.
To report a case of subcutaneous granuloma annulare and review its differential diagnoses and treatments.
A 4 year-old male patient. Since 2 and a half years of age he presented asymptomatic firm subcutaneous nodules on the back of the left middle finger and later on the back of the left hand, right big toe, left frontal area and scalp. Excisional biopsy of some lesions from the scalp was consistent with subcutaneous granuloma annulare. Clobetasol 0,05% cream twice a day for 1 month was prescribed without response.
Subcutaneous granuloma annulare must be considered within the differential diagnosis of subcutaneous nodules in children. In most of the cases a biopsy and histopathology of the lesions will be required to confirm the diagnosis. Due to its tendency to spontaneous resolution, treatment often is not necessary and periodic evaluation is recommended.
环状肉芽肿是一种良性自限性皮肤病。皮下环状肉芽肿是一种罕见的变异型，几乎仅见于幼儿，其特征为坚实的结节，更常见于下肢、臀部、手部和头皮。
报告一例皮下环状肉芽肿病例，并复习其鉴别诊断和治疗方法。
一名4岁男性患者。自2岁半起，他在左手中指背侧出现无症状的坚实皮下结节，随后在左手背、右大脚趾、左额部和头皮出现。对头皮上一些病变进行切除活检，结果符合皮下环状肉芽肿。外用0.05%丙酸氯倍他索乳膏，每日两次，持续1个月，无反应。
儿童皮下结节的鉴别诊断中必须考虑皮下环状肉芽肿。大多数情况下，需要对病变进行活检和组织病理学检查以确诊。由于其有自发消退的倾向，通常无需治疗，建议定期评估。
