Granuloma annulare - 环状肉芽肿https://en.wikipedia.org/wiki/Granuloma_annulare
环状肉芽肿 (Granuloma annulare) 是一种慢性皮肤病,表现为皮肤上呈圆形或环状排列的红色肿块。它可发生于任何年龄段,但约三分之二的患者年龄在30岁以下,最常见于儿童和青少年。

因为环状肉芽肿 (Granuloma annulare) 通常无症状,初始治疗一般采用局部类固醇。如果局部治疗无效,可考虑皮内注射类固醇。

治疗
每隔1个月进行3至5次病灶内类固醇注射,可能会取得改善。

Granuloma annulare 是一种以结节为特征的皮肤病。它不是由感染引起的,是最常见的非感染性肉芽肿性疾病。通常为良性,常可自行消退。患者常在手臂和腿部出现红色的环形斑块或肿块。该病有不同的类型,包括最常见的localized(局限型),以及generalized(广泛型)、perforating(穿孔型)、patch(斑块型)和subcutaneous(皮下型)等变异。尽管它通常不是什么大问题,但有时可能与艾滋病毒或癌症等更严重的疾病有关。
Granuloma annulare is a cutaneous granulomatous disease that is not caused by an infection. It is the most common non-infectious granulomatous disease. The disease is benign and often self-limited. Granuloma annulare usually presents as erythematous plaques or papules arranged in an annular configuration on the upper extremities. In addition to the more common presentation, termed localized granuloma annulare, other clinical variants of granuloma annulare include generalized, perforating, patch, and subcutaneous. Despite being a benign disease, it can be associated with more serious conditions such as HIV or malignancy.
