Background: Primary lymphoma of the salivary gland is not often encountered in routine practice. About 5–10% of Non-Hodgkin's lymphomas (NHLs) are found in the salivary gland, most frequently involving parotid gland. Henceforth, it is necessary to understand the distinct clinical presentations and course of primary salivary gland lymphomas as this may help guide the proper diagnosis and management of patients with these tumors. Materials and Methods: We retrospectively reviewed primary NHL diagnosed at our medical institute over a period of 2 years. Results: Five cases of primary salivary gland lymphoma were found, two involving parotid gland while other three affecting submandibular gland. None of the cases had a clinical suspicion of lymphoma. However, they were diagnosed as having NHL B-cell type on histopathology. Conclusion: Since primary salivary gland NHL is an uncommon finding, it is often overlooked as the differential diagnosis. Methods of diagnosing and treating lymphoma are different from those of other benign pathologies of the salivary gland. Therefore, a high index of suspicion is warranted to provide a quick and efficient diagnosis and treatment without subjecting the patient to unnecessary tests and procedures.
