1 Eyelid Tumors By Emily Thielke

2 Eyelid Neoplasm or eyelid tumors are found in both cats and dogs but mostly in older dogs
Some breeds that are predisposed to eyelid masses include: Poodles Labrador Retrievers Cocker Spaniel Samoyed Siberian Husky Cock-a-poo Alaskan Malamute Cairn Terrier Dachshund Shih Tzu Basset Hounds

3 Canine Eyelid Neoplasm
Usually benign May be based on clinical appearance Often originate from the glands located within the eyelid margin

4 Meibomian (sebaceous) Adenoma
Most common in dogs It rises from the meibomian gland and found near the meibomian orifice Can be confused with sebaceous hyperplasias

5 Symptoms Elevated, nodular masses and are usually 2-5 mm in diameter
May appear black or brown but often appear as yellowish or tan on cut section May exhibit alopecia, hyperpigmentation and ulceration with secondary infection May be itchy and inflamed

6 Other less common Eyelid Tumors in Dogs
Melanoma Papilloma Histiocytoma

7 Dx and Tx Fine needle aspiration with cytology followed by histopathology and tissue biopsy are often used to confirm what kind of tumor we are dealing with Surgery is often recommended to remove the eyelid tumor however they may reoccur more than once

8 Feline Eyelid Neoplasm
Less common in cats but are often more malignant Not all masses of the eyelids are tumors though. Some are fungal infections and others can be inflammation

9 Squamous Cell Carcinoma
Most common Commonly found in cats with white or pink eyelids Common in outdoor cats with prolonged sun exposure

10 Symptoms Ulcerated and reddened area on eyelid margin
Excessive tearing Mucoid or pus-like discharge from the eye Cloudiness, bluish haze or film covering the cornea Frequent pawing or rubbing of the eye Increased blinking or squinting of the eyelids

11 Other Eyelid Tumors in Cats
Basal Cell Carcinoma Fibrosarcoma Mast cell tumor

12 Dx Complete medical history and physical examination
Complete ophthalmic examination Fluorescein staining of the cornea Bacterial culture of secretions from the eye Fungal culture and cytology Fine needle aspirate Tissue biopsy Chest X-rays to look for possible spread of the tumor

13 Tx Surgical removal Surgical reconstructive techniques to preserve protection of the eye Small mast cell tumors may respond to systemic corticosteroids or locally injected corticosteroids Cryotherapy, freezing of the tumor If large enough, may also involve removal of the eye

14 Indications for Surgery
An eyelid mass should be removed : The mass becomes too large Concern about malignancy Corneal or Conjunctival irritation The patient is traumatizing the mass Also the owner may just want it removed for cosmetic purposes

15 Procedure The patient is placed in sternal or lateral recumbency
Specialized eye drapes are used ( precut hole placed over the eye and secured in place with towel clamps) Surgically clip the surrounding area and scrub Flush eye with saline to remove any debris

16 Surgical Supplies Bishop-Harman forceps Chalazion Forceps
Jaegar Lid Plate Stevens Tonotomy Scissors Needle Holders

17 Options : Wedge Resection
Chalazion forceps or Jaeger lid plate are used for stabilization A full thickness incision is made using a sharp dissection The incision is then closed using two layers

18 CVT's Role Our role in this procedure is mostly client education other than handing the tools to the DVM, assisting as the scrub nurse during the procedure or taking vitals Important issues to address to the client would be : Eyelid tumors can reoccur multiple times Monitoring their activity so as to not open the incision Monitor incision for infection and keep it clean Use of an Elizabethan collar may be needed to keep the animal from causing more trauma to the eye Follow up appointments are necessary

19 However, there is nothing we can tell the owner for prevention purposes, unless we get to educate them on the breed of dog they choose, and even then it can still happen in breeds that are not predisposed to eyelid tumors Educating them on how to care for their animal after the treatment plan is about all we can do.
