Trichoblastoma: Case Report and Review of the Literature

Trichoblastomas are benign adnexal skin tumours that occur preferentially in hairy areas. Clinically, trichoblastomas appear as well-limited nodules or papules, which may be confused with basal cell carcinomas. A positive diagnosis is made on the basis of anatomopathological examination. The gold standard of treatment is still surgery, involving complete removal of the tumour with sufficient margins, up to 5-10 mm in aggressive forms, to avoid any recurrence or malignant degeneration. This paper reports a case of giant labial trichoblastoma, highlighting the diagnostic difficulties and the importance of rigorous management.
