Abstract
Introduction: Extranodal non-Hodgkin lymphomas constitute 25–40% of all lymphomas. The most common site is gastrointestinal tract followed by head and neck area. Salivary gland is involved in 2–5% of all cases.
Case Report: We herein report a case of a 24-year-old male who presented with painless, gradually increasing mass in the region of left parotid. Imaging studies, both ultrasonography and magnetic resonance imaging (MRI), were suggestive of infiltrative mass lesion involving the left parotid gland along with evidence of suspected bony metastasis. Patient underwent total parotidectomy with excision of level II&III cervical lymph nodes. Histopathological examination supported by immunohistochemistry helped us to clinch the diagnosis of primary diffuse large B cell lymphoma of the parotid gland.
Conclusion: Non-Hodgkin lymphoma can mimic a large number of both benign and malignant disease entities of the salivary gland. Hence a high index of suspicion is required for an early diagnosis of non-Hodgkin lymphoma in a rapidly growing mass of salivary gland.

Keywords: Non-Hodgkin lymphoma, Salivary glands, Parotid gland, Diffuse large B cell (DLBCL)
