• Objective The aim of this study was to evaluate important clinical, morphological, histopathological, histochemical, and immunohistochemical characteristics in order to establish the diagnosis and prognosis of a low‐grade intra‐orbital myxosarcoma. Animal studied A mongrel dog presented a 2‐year history of a neoplastic mass behind the right eye. Results The neoplasm presented a mesenchymal spindle and stellate cell proliferation with an abundant myxoid matrix, moderate anisocariosis, and a low mitotic index. It stained positive for vimentin, moderately positive for periodic acid‐Schiff, and negative for Gomori trichrome stain and α‐smooth muscle actin. Conclusions One year following surgical excision, the patient remains disease free. The histological findings established a diagnosis of a rare canine intra‐orbital low‐grade myxosarcoma.
