Dissecting folliculitis of the scalp. A case report of combined treatment using tissue expansion, radical excision, and isotretinoin.

Dissecting folliculitis of the scalp can develop into an extensive, hypertrophic scarred lesion that is unresponsive to routine treatment. In these situations, radical excision of the affected area and concurrent perioperative treatment with isotretinoin (13-cis-retinoic acid) may be effective. The authors describe a case, illustrating the successful clinical application of this technique.
