A rare presentation of a paediatric sinonasal inverted papilloma

Abstract

Sinonasal inverted papilloma (IP) is a benign tumour with an extremely low incidence in children. We report the case of an 11-year-old Caucasian male presenting with recurrent right-sided epistaxis, nasal obstruction and a mass in the right nasal cavity. An initial diagnosis of a nasopharyngeal angiofibroma was considered; however, on detailed histological examination, the mass was found to be an inverted papilloma. This report aims to increase awareness of IP in the paediatric age group, as well as reinforcing the role of endoscopic surgery in the management of this condition.

Pediatric naso-sinusal inverted papilloma: report of a case and literature review: a case report

“…Our patient was 11 years old. IPs are recognized as benign tumors, with the potential of malignant transformation and recurrence after surgery [ 2 ]. In the rare cases reported in children, there has been only one case of malignancy.…”

“…Aetiopathogenis of IP remains icompletely understood, however, some etiologic factors such as chronic rhinosinusitis, proliferation of nasal polyps, allergy, environmental pollutants, tobacco and viruses particularly the human papilloma virus (HPV) have been reported in the literature, however, no significant evidence for this theory exists [ 2 ]. The signs and symptoms of IP in children are indistinguishable from other unilateral pediatric nasal masses and most commonly include unilateral nasal obstruction, nasal discharge, epistaxis.…”

“…It is exceptional in the pediatric population and only a handful of cases have been reported in the litterature [ 2 ]. IP is known to be a benign tumor, however, it is caractherized by its recurrency particularly if incompletely removed and its malignant transformation possibility [ 2 ]. We report in this paper a case of IP in a child dealed with an endoscopic endonasal removal.…”

Multidisciplinary approach to children with sinonasal tumors: A review

“…A sinonasal inverted papilloma presents similarly to a nasopharyngeal angiofibroma, with unilateral recurrent epistaxis, nasal blockage, and mass formation. 9 Another facial tumor that should be considered in children is a myxoma. Patients as young as 20 months have been reported to develop this tumor.…”

“…The recommended approach is endoscopic resection. A sinonasal inverted papilloma presents similarly to a nasopharyngeal angiofibroma, with unilateral recurrent epistaxis, nasal blockage, and mass formation . Another facial tumor that should be considered in children is a myxoma.…”
