abstract
A two year old cockatiel was presented to the Madras Veterinary College Teaching Hospital with a history of solitary swelling on the skin near the cloacal region past six months. Clinical examination revealed that the nodule was light yellow, firm, irregularly spherical, well demarcated, pedunculated and ulcerated. The excised biopsy mass was subjected for histopathology examination. Grossly, the mass was solitary, light yellow coloured, firm and pedunculated. Histopathological examination revealed diffuse infiltration of numerous large foamy macrophages, lymphocytes and multinucleated giant cells and numerous cholesterol clefts in the epidermo-dermis and dermis region. From the clinical examination, gross and histopathological examination, it was confirmed as cutaneous xanthoma.
