Abstract: This report describes a case of Ocular Mast Cell Tumour (MCT) diagnosed by cytological and immunocytochemical evaluation in a ten-year-old male mongrel dog presented to the Ophthalmology unit, Surgery, of Madras Veterinary College Teaching Hospital (MVCTH) with a six-month history of a progressively enlarging, ulcerating mass of the Right Upper Eyelid (OD). Ophthalmological examination revealed prolapse of the third eyelid membrane. Fine Needle Aspiration Cytology (FNAC) of the eyelid mass demonstrated numerous discrete mast cells containing characteristic intracytoplasmic metachromatic granules. Subsequent immunocytochemical analysis of the aspirate revealed discrete mast cells with intracytoplasmic metachromatic granules.Subsequent immunocytochemical analysis of the aspirate showed strong and diffuse expression of c-Kit leading to confirmatory diagnosis of mast cell tumour.
