Plain-English summary
A 7-year-old female spayed Yorkshire Terrier was brought in for a dark, raised mass on her lower left eyelid that had been slowly growing. The owner chose to have the mass surgically removed instead of doing a biopsy. The veterinarian successfully excised the mass and reconstructed the eyelid using a special flap technique. The mass was found to be a malignant melanoma, but the surgery achieved clear margins, meaning all the cancer was removed. At a follow-up after eight months, there was no sign of tumor recurrence, and while there were some minor complications, the dog's eyelid function and appearance were excellent.

Abstract
PURPOSE: To perform a reconstructive blepharoplasty to obtain complete surgical excision of a darkly pigmented raised conjunctival-eyelid mass of the lower eyelid in a dog. ANIMAL STUDIED: A 7-year-old, female-spayed, Yorkshire Terrier was evaluated for a slowly progressive, dark brown-to-black raised mass of the lower left eyelid. Sampling of the mass via fine-needle aspirate or incisional biopsy was declined, and an excision of the mass with the goal to obtain complete margins and maintain normal eyelid function with cosmesis was elected. PROCEDURES: The lower palpebral conjunctival-eyelid pigmented mass was excised en bloc and the lower eyelid was reconstructed with a mucocutaneous subdermal plexus flap. RESULTS: Histopathology revealed a malignant dermal and conjunctivalmelanoma excised with complete margins (1-2 mm). Short-term complications included corneal ulceration and eschar formation, which resolved completely at the 1-month follow-up. Long-term complications included mild trichiasis with epiphora and porphyrin staining. Tumor recurrence was not observed during an 8-month follow-up period. CONCLUSIONS: The en bloc excision with mucocutaneous subdermal plexus flap was successful in obtaining complete surgical margins for a malignant conjunctival-eyelid melanoma. An excellent functional and cosmetic outcome was achieved without tumor recurrence during an 8-month follow-up period. A mucocutaneous subdermal plexus flap can be considered as a surgical option for malignant melanoma of the lower eyelid.
