title: Trichoblastoma of the eyelid.
abstract: A 50-year-old woman developed a slow-growing tumor of the right medial canthus. Excisional biopsy and histologic examination showed a trichoblastoma. This nodule was excised using Mohs micrographic and reconstructive surgery. Trichoblastoma is a rare, slow-growing neoplasm derived from the hair follicle. Though rarely undergoing malignant transformation, these nodules histologically resemble basal cell carcinoma and generally require complete excision.
