Spindle Cell Hemangioma of Lower Lip: The Fourth Case Report with Review of Literature

Background Spindle cell hemangioma previously known as spindle cell hemangioendothelioma is a benign vascular tumour with rare presentation in head and neck. Presentation in lip is even rarer with three cases reported previously. Method This report describes a case of spindle cell hemangioma presented as an asymptomatic growth on lower lip of a 32-year-old male. Clinicopathological characterization of this case along with previously reported 15 cases of spindle cell hemangioma of head and neck were conducted. Result Microscopic evaluation shows a well-circumscribed vascular neoplasm of spindled and epithelioid endothelial cells. Large ectatic thin-walled vascular spaces were seen engorged with RBCs. The neoplasm was CD31 positive. Slight predilection for female gender and young age were observed. Minimal possibility of recurrence was also observed. Conclusion Spindle cell hemangioma needs to be considered in the differential diagnosis of vascular tumours of head and neck to avoid misdiagnosis of aggressive vascular neoplasms.
