Cutaneous myxoma in a pintagol (Sporagra magellanica X Serinus canaria)

Abstract

<p>Myxomas are benign mesenchymal tumors rarely described in birds. This report describes the clinical and pathological findings in a case of myxoma in a pintagol (<bold>Sporagra magellanica</bold>X<bold> Serinus canaria</bold>). The animal had a nodule on the dorsal region of the third digit on the left hindlimb. Grossly, it was a 0.9×0.5×0.4cm, soft, white nodule, with black and yellow areas on the cut surface. Microscopically, a well-differentiated monomorphic population of spindle cells arranged in an abundant Alcian blue-positive myxoid matrix was observed. The diagnosis of myxoma was based on the microscopic findings</p>
