Arteriovenous malformation (AVM) of the head and neck is a rare phenomenon, more so when it is an extracranial AVM like the auricle. AVMs are caused by genetic mutations. Most are probably present in the subclinical form at birth and then evolve; some may arise postnatally or during adolescence or get aggravated by precipitating factors like trauma, infection or hormonal influence like puberty or pregnancy. Once diagnosed, the feeding vessels have to be identified using radiological investigations. They are then embolised via means of percutaneous embolisation and surgical resection.

One of the differential diagnosis for Epistaxis with nasal mass is Rhinosporidiosis. Most of those patients will have history of bathing in contaminated ponds. Since the organism could not be cultured, Histopathological examination conrms the diagnosis. Treatment includes surgical excision of the lesion with cautery ablation at the base to ablate vessels feeding the lesions.
