title: Chondrodermatitis nodularis chronica helicis. A transepithelial elimination disorder.
abstract: A patient with clinically and histologically characteristic chondrodermatitis nodularis chronica helicis (CNCH) had histologic evidence of transepithelial elimination (TE). Results of a review of 10 other histologic specimens of CNCH yielded three cases with features of TE. Pictorial presentation of yet another example was found in the literature. It is suggested that CNCH should be included in the ever-expanding group of TE disorders.
