Abstract
Squamous papillomas are squamous-derived growths commonly arising from the oral cavity and oropharynx. A 75-year-old woman presented with chronic persistent left nasal obstruction and gradual painless non-axial proptosis with loss of vision in the left eye. Computed tomography scan showed an iso-dense lesion filling the frontal, left ethmoidal and sphenoidal sinuses, and the nasal cavity, with extension into the left orbit. She underwent surgical tumor resection with orbital exenteration and histology revealed features of an aggressive hyperkeratotic squamous papilloma arising from the sino-nasal region. Although squamous papillomas have been natively associated with the oral cavity and oropharynx, they present less frequently as sino-nasal tumors with orbital invasion.
Highlights
Papillomas are benign tumours with characteristic papillary projections and are among the most common benign epithelial tumours of the oral cavity in both children and adults, but most commonly seen in persons between 30 and 50 years of age [1]
Squamous papillomas have been natively associated with the oral cavity and oropharynx, they present less frequently as sino-nasal tumors with orbital invasion
Orbital invasion from sino-nasal tumors can occur via various anatomic paths and Saha et al [6] in their study, reported that inverted papillomas invaded the orbit via the sphenoid in 4% of cases, and via erosion of the lamina papyracea in 13% of cases
Summary
Papillomas are benign tumours with characteristic papillary projections and are among the most common benign epithelial tumours of the oral cavity in both children and adults, but most commonly seen in persons between 30 and 50 years of age [1]. In the head and neck region, occurrence of this lesion is relatively rare in the paranasal sinuses whereas oral squamous papilloma is the fourth most common mucosal mass in humans accounting for 3% - 4% of all biopsied lesions [4]. To the best knowledge of the authors, orbital involvement of this tumor has not been reported in Nigeria; this reports the presentation and management of sino-nasal squamous papilloma with orbital involvement in an elderly Nigerian female. This study adhered to the Tenets of Declaration of Helsinki and an informed consent was obtained from the patient for the publication of the report
