Animals attending the veterinary hospital oncology sector, diagnosed with neurofibrosarcoma carcinoma solid mammary or neurofibrosarcoma hemangiopericytoma, underwent surgical tumor removal together with skin reconstruction.
To further determine the cell line of origin, immunohistochemical labeling for S100 protein (rabbit polyclonal anti-SlOO at 1:100, Novocastra, Newcastle, UK), CD34 (goat polyclonal anti-CD34 antibody at 1:80, Santa Cruz Biotechnology, Santa Cruz, CA, USA), smooth muscle actin (SMA; mouse monoclonal anti-SMA antibody at 1:100, Dako, Carpinteria, CA, USA), and vimentin (mouse monoclonal antivimentin antibody ViM3b4 at 1:50, Dako) was performed on 5-pm serial sections of the mass as follows: brain for S100 protein; uterus for SMA; haired skin for vimentin; and hemangiopericytoma for CD34.

(2013) performed an intraoperative clinical diagnostic assessment of meningioma, choroidal plexus papilloma, glioma, and hemangiopericytoma with FF-OCT [85].
Histological examination showed the following: 5 cases of malignant peripheral nerve sheath tumor, 4 cases of undifferentiated pleomorphic sarcoma, 3 cases of osteosarcoma and chondrosarcoma, 2 cases of chordoma, giant cell tumors of bone, and leiomyosarcoma, and 1 case each of malignant solitary fibrous tumor, malignant myoepithelioma, plasmacytoma, malignant lymphoma, histiocytic sarcoma, and hemangiopericytoma. Sixteen of the 27 cases were managed with surgery (59%).
The differential diagnosis of the lacrimal gland MEC on imaging includes inflammatory myofibroblasts tumour, solitary fibrous tumour, alveolar soft part sarcoma, giant cell angiofibroma fibrous histiocytoma, and hemangiopericytoma. Since imaging findings are not characteristic for a definitive diagnosis of MEC, histopathological evaluation is needed.
