Upper eyelid and medial canthus reconstructive surgery after histiocytoma resection in a dog: a case report

A six year old crossbred male dog presented with non-pigmented, pale pink, unhaired, ulcerative tumor of the medial canthus and upper eyelid region. As treatment, surgery was proposed. During the surgery complete excision of the tumor was performed. The extent of skin loss, especially in the upper eyelid required plastic reconstruction by pedicle flap transposition. The soft skin of the cheek was chosen as a graft donor site. The postoperative period proceeded without any complications and ended with successful engraftment. The soft cheek skin did not impede movement of the upper eyelid. Histopathological examination indicated histiocytoma and tumor-free excisional margins were confirmed. There has been no recurrence during the subsequent 12 month period.
