Abstract

A 1-year-old castrated male Shih-Tzu dog presented with severe orbital swelling involving the right eye. Physical examination identified a painless swelling of the right periocular tissues and protrusion of the third eyelid. Radiographic examination revealed a well-delineated, spherical (3 × 3 cm) soft tissue mass. Ultrasonography confirmed a hypoechoic, multilobular, tubular cystic structure with hyperechoic foci. Fine needle aspiration was conducted and the cytologic impression revealed copious mucus, increased neutrophilic leucocytes, and foamy macrophages. Th tentative diagnosis was zygomatic sialocele, and the lesion was resected through lateral orbitotomy. Surgical exploration identified a multilobular mass adhering to the zygomatic glands. Both the zygomatic gland and the mass were removed. Histological findings were consistent with those of an inflamed myxoma. No postoperative recurrence occurred within 1 year.
