Spindle Cell Neoplasm of Left Supra Scapular Region: Rare Case
Abstract: One challenging feature of head and neck pathology is that a dizzying array of spindle cell lesions occurs here ranging all the way from reactive to malignant and very aggressive. Most SPN are overtly malignant, and the differential diagnosis then includes a number of different malignant spindle cell neoplasm. However, there are several benign or even non-neoplastic lesions that can sometimes be difficult to discern from SPN. The pathologic and …
