A number of benign and malignant spindle cell tumours which encompass desmoid fibromatosis, sinonasal hemangiopericytoma, solitary fibrous tumours, leiomyosarcoma, and epithelioid haemangioendothelioma must be differentiated from this entity. Distinction between fibrosarcoma and desmoid fibromatosis at this location is based on the sparse cellularity and the fibrotic stroma, while differential diagnosis with leiomyosarcoma is based on the detection of smooth muscle features by immunohistochemistry [54–57].
