新生儿肛周皮炎

定义

新生儿肛周皮炎在出生后第一周会出现肛周红斑，在更严重的情况下可能发展为水肿和肛周皮肤浅表糜烂。尽管通常单独发生，但肛周皮炎有时可能与原发性刺激性尿布皮炎有关。与母乳喂养婴儿相比，它在接受配方牛奶婴儿中更为常见；认为是对粪便成分的刺激性反应。

Perianal dermatitis of the newborn presents with perianal erythema during the first week of life, which in more severe forms may progress to oedema and superficial erosion of perianal skin. Although it usually occurs alone, perianal dermatitis may sometimes be associated with primary irritant napkin dermatitis. It is commoner in infants receiving cow's milk formulations than in breast-fed infants; it is assumed that it represents an irritant response to faecal constituents.
