This article describes a case of sebaceous
carcinoma located on the right lower eyelid of an 11-year-old female Haflinger
horse and its surgical, clinical, and histopathological aspects. The Haflinger
horse was referred to the clinics of the Department of Surgery with a complaint
of a swelling on the right lower eyelid, which had been present for 1 year and
began to grow during the past few months. A clinical inspection revealed a
soft, multinodular tumoral mass, with the dimensions of 4×5 cm, located in the
inferior region of the right lower eyelid and protruding outward. The surgical
removal of the mass was decided after the clinical inspection. The excised tumoral
mass was submitted to the department of pathology for histopathological
evaluation, which revealed well-circumscribed multilobular structures
comprising foci of round-to-ovoid and polygonal pleomorphic neoplastic
epithelial cells with prominent nuclei and eosinophilic cytoplasm separated by
bands of the fibrous tissue of varying thickness. There was prominent cellular
pleomorphism; some cells contained cytoplasmic vacuoles of various sizes,
whereas some exhibited sebaceous differentiation. Based on these
histopathological findings, sebaceous carcinoma of the sebocyte type was
diagnosed.
