An Angiomatous Antrochoanal Polyp with Epistaxis and Bony Destruction

Abstract

Angiomatous polyps are rare sinonasal masses and may present with intense epistaxis. Angiomatous antrochoanal polyps are rare variants of antrochoanal polyps, and their diagnosis and management requires more detailed evaluation in respect to classical antrochoanal polyps. In both antrochoanal polyps and angiomatous polyps, bone destruction is an exceptional finding. The signs of bone destruction and epistaxis suggest additional pathologies including inverted papilloma, lobular capillary haemangioma and carcinoma as differential diagnoses. In this case, total excision of a left-sided angiomatous antrochoanal polyp with bone destruction was managed with nasal endoscopic approach. Troublesome intraoperative bleeding was avoided with effective additional measures.
