Plain-English summary
A 12-year-old Keeshond was diagnosed with a tumor behind the eye, known as a malignant fibrous histiocytoma. The vet performed surgery to remove the tumor and part of the surrounding bone, and the dog's vision was preserved after the operation. For 10 months, there were no signs of the tumor coming back. Unfortunately, 17 months later, the dog developed serious symptoms like not eating, diarrhea, and weight loss, and was euthanized.

Abstract
A retrobulbar malignant fibrous histiocytoma was diagnosed in a 12-year-old castrated male Keeshond dog. The mass was excised with a lateral orbitotomy and zygomatic arch resection. Vision was preserved in the affected eye, and no recurrence was noted up to 10 months postoperatively. Malignant fibrous histiocytoma originates from primitive mesenchymal stem cells. The malignant fibrous histiocytoma seen in our patient was most consistent with the storiform-pleomorphic variant, given the storiform arrangement of spindle cells, the presence of histiocytoid cells, and a mixed inflammatory infiltrate, without giant cells. The metastatic potential of malignant fibrous histiocytoma in general, and the storiform variant in particular, is unknown. Seventeen months later the dog was presented to the referring veterinarian with anorexia, diarrhea, weight loss and bilateral purulent nasal exudates. The dog was euthanized without necropsy.
