The paper discusses a case of an unusually located eyelid dermoid diagnosed in a 4-month-old, female Cane Corso dog. The observed dermoid was black and brown, located in the eyelid conjunctiva of the left lower lid, covered with keratinising epithelium, and only visible once the eyelid was pulled back. The altered conjunctival surface displayed short, thin hairs. At the 1/3 of the central and side conjunctival border, two hairs were found which suggested additional eyelash growth – on examination, the black hair proved to be a distichiasis, while the other, beige, was a hair growing out of the dermoid. The eyelid border over the evaginated area was thinner, which could only be determined once the eyelid was pulled back. The dermoid was surgically removed along with a fragment of the eyelid. Histopathological examinations revealed the presence of regular skin structures. The surface layer comprised stratified epithelium indicative of slight hyperkeratosis. The dermis displayed numerous follicles in various stages of development, accompanied by sebaceous and sweat glands. On the basis of the location and histopathological analysis, the lesion was classified as a dermoid.
