“…Xanthomas are granulomatous non-neoplastic masses which can be found in the distal parts of the wings, legs, sternum and featherless skin. 9,10 Gross¯ndings are white to pale yellow masses that have a soft and brittle texture. Also, bleeding and ulcerations may sometimes be seen on the surface.…”

CASE REPORT: LIPOSARCOMA WITH MICROVASCULAR PROLIFERATION IN A COCKATIEL (Nymphicus hollandicus)

et al. 2019

A five-year-old female cockatiel weighing 117 g was presented with a fast-growing mass beside the uropygial gland. Excisional biopsy was performed and the mass measured [Formula: see text][Formula: see text]cm in size and weighed 30.6 g. On the surface of cut sections, the mass was yellow-brown with white or yellow colloidal substances and red exudate. Histopathology showed that the tumor mass was covered by the skin and located in the deep dermis and hypodermis. The tumor consisted of abundant vascular adipose tissue and lipoblasts with intracytoplasmic lipid droplets, which varied in size. Also, small, well-differentiated blood vessels, with varied degrees of congestion and dilation, were observed within the tumor. Histochemically, staining with Oil red O produced a positive reaction in which the lipid droplets presented a reddish color. Immunohistochemistry produced positive staining for Desmin and successfully marked the muscular layers of blood vessels. On the basis of these results, a rare case of liposarcoma with microvascular proliferation adjacent to the uropygial gland was diagnosed in a cockatiel.

“…Lesions are often associated with other lesions such as lipomas, hernias or areas of irritation 9 . A recent article reviewed reports of xanthomas in numerous avian species, and lesions were reported to occur in varied locations including the oral cavity, peri‐articular regions and the liver 10 . Another article reported xanthomas on the eyelids of Amazon parrots, but no reports of conjunctival xanthomas in birds were found in the literature 9…”

A 17-year-old female blue and gold macaw (Ara ararauna) presented for evaluation of a discreet, conjunctival mass of the OD. No other abnormalities were found on ophthalmic or physical examination. A heterophilic leukocytosis was present on the complete blood count, and elevated aspartate aminotransferase activity, creatinine kinase activity and cholesterol were present on the plasma biochemistry panel. Surgical removal of the mass was complete and no recurrence has occurred by six months after excision. Reduction of dietary fats was recommended to reduce serum cholesterol levels and reduce the likelihood of future occurrence of xanthomas in this bird.

“…Tracheal xanthogranulomatosis has recently been reported in a hawk as a possible complication of trauma consecutive to repeated intubation. 6 In humans, xanthomas are characteristically distributed at sites subjected to pressure or minor trauma (elbows, knees, buttocks). 11 In this pelican, the lesions were located in the sternal region that is frequently subjected to pressure in grounddwelling avian species.…”

A great white pelican (Pelecanus onocrotalus) was referred for assessment of a subacute-onset, nonpainful swelling located in the pectoral region. Physical examination revealed a firm, round, well-circumscribed subcutaneous mass approximately 10 cm in diameter. Cytological evaluation of a fine needle aspirate of the mass was consistent with a mesenchymal tumor. The mass was excised, and a diagnosis of xanthomatosis was made based on histopathologic results. Avian xanthomatosis is a nonneoplastic condition of unknown etiology. Possible causes of this condition include trauma, metabolic or nutritional disorders. Similar lesions were not observed in the nine conspecifics that were fed the same diet and housed in the same enclosure. To our knowledge, this is the first report of xanthomatosis in the family Pelecanidae.
