Lower Eyelid Desmoplastic Trichoepithelioma

ABSTRACT

Purpose@#To report a rare case of lower eyelid desmoplastic trichoepithelioma.Case summary: A 56-year-old woman presented to our clinic with a slow-growing, painless, recurrent mass located in the temporal area of the left lower eyelid margin. Surgical incision had been performed on a similar mass 4 years before. On examination, a 7 × 2-mm firm, nodular, nontender mass was palpable in the left lower eyelid. The lesion was isolated from the surrounding tissues and completely excised. Histopathologically, the excised mass showed small strands of basaloid cells, keratinous cysts, and focal calcification. These findings supported a diagnosis of eyelid desmoplastic trichoepithelioma. @*Conclusions@#Because of its rarity and solitary features, eyelid desmoplastic trichoepithelioma can be confused with sclerosing basal cell carcinoma. Thus, the goal of surgical therapy should be complete excision; histopathological analysis should be also performed.
