Abstract:
The purpose of this report is to detail the unique occurrence of comedo-like trichoadenoma of the upper eyelid. A 54-year-old man underwent surgical resection of the lesions of the left upper eyelid that were suspected to be dilated pores. The lesions were studied with histopathological examination. Histopathology showed lesions in the dermis and epidermis containing keratinous cysts surrounded by interstitial edema and infiltration of lymphocytes. The lesions were finally diagnosed as trichoadenoma.
