Abstract

In recent years the phenomenon of transepithelial elimination has been found to be the underlying mechanism in a variety of skin disorders. "Perforating dermatoses" may show transepidermal or transfollicular elimination or a combination of the two. A case of papular granuloma annulare is reported, where in one lesion the pilary apparatus actively participated in the elimination of necrobiotic collagen from the dermis. To our knowledge, perforating granuloma annulare with a transfollicular pathway has not previously been described. Also, a classification of perforating dermatoses is presented.

摘要

近年来，经上皮消除现象已被发现是多种皮肤疾病的潜在机制。“穿通性皮肤病”可能表现为经表皮或经毛囊消除，或两者兼而有之。本文报告了一例丘疹性环状肉芽肿病例，其中一个皮损的毛囊结构积极参与了从真皮中消除坏死性胶原的过程。据我们所知，此前尚未描述过经毛囊途径的穿通性环状肉芽肿。此外，还提出了穿通性皮肤病的分类。
