“…Bovine hamartoma cases have been documented in the gingiva (Maxie and Jubb 2015;Martin et al 2020), testis (Tyler et al 1995) and liver (Ladds 1983), however, there have been no reported eyelid hamartomas in cattle. Hamartomas have been reported as a being subcutaneous, subconjunctival or orbital masses, and histologically consist of fully differentiated collagen rich connective tissue interspersed with variable amounts of adipose, vascular, muscle and nerve tissue (Dubielzig 2002).…”

“…In veterinary medical literature, hamartoma cases are well documented in animals in many different locations on their bodies (Ladds 1983;Tyler et al 1995;Dubielzig 2002;Kafarnik et al 2010;Storms et al 2014;Leiter Herran et al 2017;Martin et al 2020;Morais et al 2020). Amongst the bovine hamartomas, gingival vascular hamartomas and bovine cutaneous angiomatosis are well-known examples (Maxie and Jubb 2015).…”

A 2-day-old calf was presented with a bilateral mass in the medial canthus of the upper eyelid. The masses were removed surgically. The morphological diagnosis was a bilateral hamartoma characterised by an abnormal mixture of tissue indigenous to that area including blood vessels, striated muscle bundles, adipose tissue, isolated cartilage and nerve bundles. No recurrence developed in the 6 months following the surgical removal. Overall, although this congenital defect is relatively rare, it should be differentiated from eyelid tumours such as haemangiomas, squamous cell carcinomas, Meibomian gland tumours, dermoid cysts and teratomas in cattle.
