Malignant giant cell tumor of soft parts in a mare.
Two subcutaneous masses were removed from the elbow of a mare. Histologically they were composed of islands of polygonal to plump spindlelioid cells with large nuclei, coarsely stippled chromatin, and eosinophilic cytoplasm. Findings were diagnostic for a malignant giant cell tumor of soft parts, a rare tumor with a fair prognosis.
