Multiple infundibular tumours of the head and neck.

A condition of multiple benign and sometimes self-healing infundibular tumours of the skin is described. It effects the sun-exposed areas of the head and neck in Caucasians. The individual lesions consist of a cluster of thick pockets, representing in many details the supra-sebaceous portions of the follicular unit. Follicular poroma, tumours of the deeper part of the follicular infundibulum, virus warts, inverted follicular keratosis and prurigo nodules do not correspond adequately with the appearance described in the present series of six cases.
