Twelve years' observation of multiple familial trichoepithelioma with squamous carcinoma

Abstract

Long-standing trichoepithelioma lesion on scalp with 12 years follow-up. The patient was observed for 12 years, and the carcinoma recurred 3 times during 8 years after surgical excision and radiation therapy. Malignant transformation may occur in multiple familial trichoepitheliomas; Moderate radiation therapy should be given for malignant transformation patients with lower radiation dose and shorter time. Removing the trichoepithelioma as soon as possible if the tumor suddenly or continuously increased is recommended.
