Purpose: We report an unusual trichoblastoma of the lower eyelid. Case summary: A 74-year-old male presented with an asymptomatic 0.6 × 0.4-cm left lower eyelid tumor that had developed 3 years prior. On histological examination, a 0.3 × 0.3-cm intradermal tumor that was not connected to the epidermis was observed. The tumor was multilobular, and was surrounded by fibrous stroma and connective tissue. The tumor lobules consisted of basaloid cells, and a few keratinizing cysts were evident. These features are consistent with a trichoblastoma. We observed no recurrence at 1 year after complete resection. Conclusions: Trichoblastoma (a rare, benign skin tumor) is histologically similar to basal cell carcinoma but the prognosis is excellent after complete resection. Trichoblastoma should be considered during the differential diagnosis of basal cell carcinoma of the eyelids. © 2022 The Korean Ophthalmological Society.
