A Rare Otological Presentation of Squamous Papilloma

Abstract

Introduction:

Squamous papillomas (SPs) are benign epithelial neoplastic lesions commonly found in skin, oral mucosa, upper aerodigestive tract and genitals. Involvement of external auditory canal (EAC) by SP is extremely rare and whatever scarce literature is available is in the form of case reports. The exact incidence of this entity is still unknown. Consequently, its etiology, histopathological features, differential diagnoses and optimal management merit a better understanding by the Otolaryngologists.

Case report: We present a case of EAC SP in a 15 year old girl hailing from north-eastern India who presented to us with a mass in the EAC which was acutely painful. Contrast Enhanced Computed Tomography remained the gold standard and imaging study of choice for evaluation. However, the diagnosis was clinched only by histopathology. We also discuss our strategy of management along with a brief review of literature.

Conclusion:

Squamous papilloma has rarely been reported to affect the EAC. Human papilloma virus remains the most consistent etiological agent. Advanced imaging like contrast enhanced high resolution computed tomogram remains gold standard to evaluate any mass seen in EAC. Complete excision with cold steel technique or coblation with good post-operative care and follow up is the standard of care.
