title: Primary Non-Hodgkin Lymphoma of frontal sinus diagnosed by fine needle aspiration cytology.
abstract: We present a rare case of primary non-Hodgkins Lymphoma of the frontal sinus diagnosed by Fine needle aspiration cytology (FNAC). FNAC is a safe, simple, rapid and effective technique that could be used to diagnose lesions even in unusual sites like paranasal sinuses with effective radiological guidance. Neoplasms of the frontal sinus could be easily misdiagnosed as an inflammatory process clinically. FNAC is a simple test to rule out a neoplasm. A review of a single case including radiographic, clinical, and pathologic findings was done, followed by a discussion on the pathological differential diagnosis highlighting relevant literature. Timely diagnosis is critical in the management of these cases.
