title: [Proliferating trichilemmal tumor of the pulp of a finger: case report and review of the literature].
abstract: Trichilemmal cyst is a benign tumor, developed from hair follicle, located mainly at the scalp. We report a clinical case of unusual location at the finger pulp confirmed by histology. The main differential diagnosis in this reported case was a whitlow. The origin of this cyst is probably the nail matrix whose keratinization is trichilemmal. Surgical excision biopsy allowed a good clinical outcome.
