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.
The aim of the experiment was to develop a new surgical treatment of the follicular conjunctivitis of third eyelid in dogs by means of the surgical CO2 laser, and to evaluate its effectiveness. Material and Methods. Surgical ablation of follicles by means of a CO2 laser (Aesculight) was performed on 10 dogs with the follicular conjunctivitis of the third eyelid unsusceptible to pharmacological treatment. The following parameters were assessed: intraoperative bleeding and the duration of surgery, postoperative presence of discharge or bleeding, desire to scratch the treated area, blepharospasm, and third eyelid deformity. Results and conclusions. The selected setting of the laser made it possible to carry out the procedure with reduced carbonization and good visibility in the operating field. The mean duration of the procedure was 47.4 seconds (± 15.10). The presence of discharge was noted for up to 3 days after surgery. No recurrence of follicular inflammation was observed. Surgical treatment of lymphoid follicles with the CO2 laser ensures a quick and effective execution of the procedure, resulting in a good clinical effect and postoperative comfort of the animal.

The eyelids represent a structure composed of skin and cutaneous appendages, including hair follicles and glandular structures. The eyelids and ocular adnexa comprise the primary surface defence for the globe, specifically the cornea. There are three main forms of ciliary disorders: distichiasis, trichiasis and ectopic cilia. The abnormally placed hairs irritate the cornea. The affected eye will become red, inflamed and may develop a discharge. In severe cases, the cornea may became ulcerated. Both upper and lower lids may be involved. Some breads are affected more, suggesting that it is an inherited trait. Ciliary abnormalities are extremely rare in the cat. The diagnosis is made by direct visualization, although head loupe or slit-lamp magnification is helpful. The abnormal eyelashes are best removed through the use of surgery, kryotherapy or electroepilation. This report documents bilateral distichiasis in west highland white terrier. The distichia were removed using electroepilation technique.
