초록
Benign vascular tumors are relatively common in the head and neck region, but are rarelyfound in the ear. Among vascular tumors, infantile hemangioma stands as the prevailing enti-ty, characterized by a rapid initial proliferation of endothelial cells, succeeded by a gradual re-gression over the course of several years. In contrast, arteriovenous malformation (AVM) is aless common phenomenon, originating from peripheral vascular anomalies during embryo-genesis, and it does not undergo spontaneous regression. Specifically, the occurrence of AVMwithin the external auditory canal are exceedingly uncommon. Here, we describe a case of a49-year-old male patient who had a mass incidentally discovered in the external auditory ca-nal, but refused initial treatment. He later returned as the mass enlarged. This case could havebeen clinically misdiagnosed as a hemangioma, but was ultimately diagnosed pathologically as an AVM.
