Angiomatous Nasal Polyps in a 43-Year-Old Female From North-Central Nigeria: A Case Report

TL;DR

A rare case of angiomatous nasal polyp in a 43-year-old Nigerian woman is reported, highlighting the importance of considering this condition in adult patients with nasal blockage.

Contribution

This case report adds to the limited literature on angiomatous nasal polyps in adult females, emphasizing diagnostic considerations.

Findings

Angiomatous nasal polyps can occur in adults and should be considered in differential diagnosis.

The case highlights the need to distinguish ANPs from benign and malignant vascular tumors.

The patient presented with obstructive nasal symptoms typical of nasal polyps.

Abstract

Angiomatous nasal polyps (ANPs) are uncommon variants of nasal polyps, which, like their more common counterparts, are a significant and common cause of morbidity for patients, regardless of demographic variations. As a group, nasal polyps are non-neoplastic and commonly arise within the maxillary antrum, sphenoid, and ethmoid sinuses, protruding via the ostia into the nasal cavity. Their precise cause is unknown, but several factors related to genetics, local infections, family history, and environment have been implicated in their etiopathogenesis. ANPs are commonly diagnosed in the younger age group and are particularly significant because they may mimic benign and malignant vascular tumors occurring within the nasopharynx.

We report a rare case of angiomatous nasal polyp in a 43-year-old Nigerian female. ANPs should be included in the differential diagnosis of mass lesions of the nasal cavity in adult patients (male or female) who present with obstructive symptoms and should be distinguished from both benign and malignant neoplastic mimics.
