Introduction Hemangioendothelioma is a rare variety of vascular soft tissue neoplasm, classified as a borderline tumour with diverse modality of clinical presentation. It is seen mostly at sites like the liver, lungs and bones while very few head and neck cases have been reported. Case Report A rare case of an unusually large tumour mass presenting as an anterolateral neck mass with extensions to right parapharyngeal space, posterior triangle and prevertebral space is presented here. The entire tumour was removed en-masse surgically. Histopathological examination confirmed the mass to be an epitheloid hemangioendothelioma, the enormous size of which in the neck makes it unique and unusual.
