Abstract

Trichoblastoma is a rare benign adnexal tumor exhibiting follicular differentiation and is widely familiar for its resemblances with basal cell carcinoma. We report a case of giant trichoblastoma manifesting as a huge cutaneous nodule misdiagnosed as dermatofibrosarcoma on clinical and radiological grounds. The diverse histological features responsible for its uniqueness are discussed along with a brief review of histogenesis and histological subtypes.
