  "abstract": "Objectives: Angiosarcoma is a rare malignant vascular tumour. Its occurrence in the nasal cavity is uncommon, and septal cases are particularly rare. Because symptoms are often non-specific, nasal septal angiosarcoma may initially mimic benign vascular lesion and delay diagnosis.\n\nMethods: We report a 46-year-old woman with recurrent epistaxis and nasal obstruction. Nasal endoscopy and excisional biopsy were performed, with histopathology and immunohistochemistry.\n\nResults: Endoscopy revealed a 1.0 × 0.5 cm mass on the anterior septum. The lesion appeared completely excised on gross inspection; however, histopathology demonstrated infiltrative margins with residual tumour at the resection edges. Microscopy showed irregular vascular channels, pleomorphic endothelial cells, high mitotic activity and focal necrosis. Immunohistochemistry confirmed endothelial differentiation. No cartilage invasion was identified on histology.\n\nConclusion: This case highlights the diagnostic challenge of nasal septal angiosarcoma and the emphasises the importance of early biopsy, histopathological confirmation and multidisciplinary management.",
