Successful treatment of meibomian carcinoma in a cow

Tratamiento exitoso del carcinoma de meibomio en una vaca

Objective. The aim of this study was to present the diagnosis and treatment method of an extraordinary meibomian carcinoma in a cow. Materials and methods. A 5-year-old, Holstein cow presented with a right lower eyelid mass with ocular signs of mucopurulent discharge, conjunctival hyperemia and ocular discomfort. On physical examination, it was noted that the general condition was good, but there was a mass lesion in the third eyelid. The mass arising from the inner surface of the right lower eyelid was surgically excised and examined histopathologically. Results. The tumor mass was defined as meibomian carcinoma after microscopic examination. Conclusions. Meibomian carcinoma is a rare disease that shows certain features of malignancy such as invasion and pleomorphism as well as mitosis. This case presentation can be considered to contribute to the literature as this is a rare tumor in cattle, to the best of our knowledge it is the first report of a case originating from the third eyelid, and wide surgical excision was sufficient for treatment.
