Trichilemmal carcinoma of the scalp.

This report describes the case of an 86-year-old male who presented with a large scalp tumour. Imaging revealed a large vertex mass, without intracranial extension, and multiple nodular subcapsular hepatic lesions suspected to be secondary in nature. Surgical resection was performed. Pathological examination revealed an adnexal carcinoma of follicular origin, thus a trichilemmal carcinoma. Controlled wound healing (budding of the diploë) was completely successful within 12 months. The patient refused the assessment and treatment of his metastases.
