Rabbit with painless cheek swelling treated by surgery

Abstract

ABSTRACT The present report aimed to describe the main characteristics of the parotid salivary mucocele in an adult male rabbit, which presented with a painless fluctuating mass with fluid content. Owing to the need for repeated fluid drainage, surgical excision was the chosen mode of treatment. Preoperative evaluation included radiography and blood analysis. The patient underwent surgical excision of the affected gland. Inhalation anesthesia was maintained by means of isoflurane and the cardio-respiratory parameters were monitored throughout the surgery. A bipolar electrocautery was used to assist in the incision and polyglactin 910 and nylon were the suture materials used in the wound closure technique. Post-operative medications included analgesics, anti-inflammatory agents and antibiotics. Histopathology of the excised glandular tissue revealed a mixed inflammatory infiltrate, fibroblasts, hemorrhage and hyperemia. The observations in this case suggest that surgical excision of the affected gland is the treatment of choice for the management of mucocele in companion rabbits, which has already been identified for other animals. Periodic acid-reactive Schiff staining confirmed the diagnosis of salivary mucocele. The complementary investigations helped to rule out the differential diagnosis and indicated a favorable prognosis, in view of the fact that the case was successfully resolved without complications or recurrence.
