Abstract

Trichogenic tumors are very rare and described as cutaneous neoplasms probably derived from hair germ which develops into hair follicles. We report a case of trichoblastic fibroma on the left parietal scalp of a 45-year-old man. The lesion was a solitary, firm, non-tender, 2×2cm subcutaneous nodule. The histopathological study showed a well circumscribed dermal tumor composed of abundant basophilic palisading basaloid lobules with some keratinous cysts, hair follicle differentiation and fibroblastic stroma.
