ABSTRACT
Diffuse large B-cell lymphoma (DLBCL) is the most common type of Non-Hodgkin Lymphoma (NHL). The primary NHL of the nasal cavity and paranasal sinuses are extremely rare, hence causing diagnostic and therapeutic difficulties. We present the case of a 53-year-old woman with 1 week history of left frontal headache followed by swelling over left frontal region. She was initially treated as left frontal sinus Pott’s Puffy Tumour based on clinical and radiological investigation. Biopsy was taken and histopathological investigation revealed high grade DLBCL of left frontal sinus. She was then referred to haematology department for chemotherapy. Eventually, she succumbed due to progression of disease. In conclusion, an early diagnosis of DLBCL of the frontal sinus is difficult as it is often confused with other nasal pathologies and causes a delay in treatment.
