Sebaceous carcinoma of the eyelid (malignant adnexal tumour with sebaceous differentiation): A. Lobules of atypical pleomorphic cells, some with vacuolated cytoplasm featuring sebaceous differentiation (left side, shown by arrow) (HE stain, x400); B. Lobules of tumour cells in the dermis showing comedocarcinoma pattern (asterisk) and intraepithelial spread of tumour (arrow), an important feature indicating poor prognosis (HE stain, x100).

Purpose To investigate the usefulness of diathermy thermocoagulation in chalazion surgery. Methods This prospective, observational study included 30 sides from 24 patients who underwent chalazion surgery using diathermy thermocoagulation. The eyelid was fixed with a chalazion clamp under local anesthesia. The skin or palpebral conjunctiva was inci...
