Purpose: To describe an original surgical resection of a palpebral extensive squamous cell carcinoma in a cat. Material/Methods: A seven-year-old female European short-haired cat was referred due to the presence of an ulcerative tumor in the region of the medial canthus of the lower right eyelid. The lesion progressed over three months. After pre-operative eval- uations including a CT scan of the skull and thorax, the surgical technique consisted in a deep wide local excision and a two-stage blepharoplasty: first of all, a lip commissure to eye- lid transposition flap to repair the palpebral side, and then a frontal transposition flap to repair the nasal side. Postoperatively, antibiotics (amoxicillin/clavulanic acid) and non- steroidal anti-inflammatory drugs (meloxicam) were administered systemically in combina- tion with topical ophtalmic lubrication. The cat was re-examined at three, seven, fourteen and ninety days later. Results: One year later, both the aesthetic and functional aspects were acceptable without trichiasis, and no local recurrence was observed. Discussion: In the surgical management of an extensive squamous cell carcinoma, mainly on the lower eye- lid near the medial canthus, the challenge consists of replacing the palpebral tissue defect with an anatomically comparable flap, with primary surgical closure to avoid tissue etraction. Using skin flaps, we show that this can be performed by associating the transposi- tion of a mucocutaneous subdermal plexus flap, and the transposition of a frontal flap, with satisfactory recovery of tissue function.
