Sinonasal Carcinoma Mimicking Invasive Fungal Sinusitis: A Diagnostic Dilemma of an Extensive Paranasal Sinus Mass, a Case Report

Abstract

Tumors of the paranasal sinuses are rare. Usually, patient’s presents at an advanced stage of the disease as the initial symptoms are nonspecific and the tumour remains indolent from any months or even years, leading to not only delay in diagnosis but a conundrum in diagnosing this entity. Herein we are reporting a case of sinonasal carcinoma in a gentleman which was initially diagnosed as invasive fungal sinusitis. Patient’s initial presentation as well as the radiological investigation led towards the diagnosis of chronic invasive fungal sinusitis. The histopathological examination of the lesion was suggestive of sinonasal carcinoma. We would like to highlight the challenge in diagnosis as well as the management of this entity.
