Liposarcoma in a Common Quail (Coturnix coturnix): A Case Report

Area of Science:

• Veterinary Oncology
• Avian Pathology

Background:

• Liposarcoma is a rare malignant soft tissue tumor occasionally reported in birds.
• Understanding avian liposarcoma presentation, diagnosis, and management is crucial due to its rarity.

Observation:

• A 2-year-old female common quail presented with a rapidly growing abdominal mass near the uropygial gland.
• The mass recurred post-surgery, and diagnostic tests indicated an inflammatory response and tumor-related metabolic disturbances.
• Histopathology and immunohistochemistry confirmed a well-differentiated liposarcoma.

Findings:

• A 3.5 cm liposarcoma composed of lipid-rich neoplastic cells was identified.
• Immunohistochemical markers Vimentin and S-100 confirmed the liposarcoma diagnosis.
• Surgical excision, the primary treatment, showed high recurrence rates in avian cases.

Implications:

• Accurate diagnosis of avian liposarcoma relies on histopathology and immunohistochemistry.
• Further research is needed to develop effective therapeutic strategies for avian liposarcoma.
• This case underscores the challenges in managing liposarcomas in birds, emphasizing the need for advanced diagnostic and treatment protocols.
