Primary lymphomas of paranasal cavities are rather uncommon entities. They have a variable presentation from fulminant destructive manifestations to chronic indolent type of disease. Chronic indolent form may mimic invasive fungal sinusitis in its presentation. Unless high index of suspicion is held and appropriate histopathology sections are taken from specimen, its diagnosis can be deceitful. We here by report a case of primary lymphoma of the paranasal sinuses which was radiologically and clinically suspected to be a invasive fungal sinusitis and later was proven to be a B cell lymphoma. Clinical similarities between lymphoma and invasive fungal sinusitis along with management issues are discussed in this article.
