Abstract
Myxoma is a benign mesenchymal tumor of skin and soft connective tissues considered to be of fibroblastic origin. A female bearded dragon (Pogona vitticeps) with a raised mass on the left side of the body was referred to the Faculty of Veterinary Medicine, University of Tehran, Tehran, Iran.The mass had become evident and grew more extensive within the previous 11-month period. The dragon was anesthetized with 5.00% isoflurane, and the mass was removed surgically. Tissue samples of the mass were fixed in 10.00% neutral buffered formalin, sectioned and stained with Hematoxylin and Eosin  (H&E), Alcian blue (pH: 2.50), and periodic acid Schiff (PAS) staining techniques. The patient was administered meloxicam, lincomycin, and marbofloxacin. Histopathologically, the capsulated mass was composed of myxoid structure. Stellate-to-reticular cells distributed in a mucinous stroma containing few tiny blood vessels were seen. Myxoid cells displayed a PAS-positive cytoplasm. The myxomatous matrix was alcianophilic at the pH of 2.50. To our knowledge, this is the first report of surgery, treatment, and histopathological study of myxoma in a bearded dragon (P. vitticeps). The sutures were also removed 12 days after the operation. No new growth of the mass was observed three months following the surgical procedures.
