Congenital Synchronous Adenomas of Meibomian and Moll Glands of the Eyelid in a Calf

Abstract

This report describes meibomian adenoma (MA) and moll gland adenoma in a female, 1.5-months-old, crossbreed calf. Macroscopically, the mass was 3 x 1.5 x 0.5 cm in size and 5.35 g in weight; its shape was gray-reddish and it was localized on the right lower eyelid. Microscopically, the mass was composed of lobules of various sizes separated with a septum, which included well-differentiated sebaceous cells and apocrine secretory epithelium, with no an association of both gland types.
