Marginal Cell Lymphoma Presenting as a Primary Submandibular Tumor

Primary lymphomas of the salivary glands are rare tumors seen in the head and neck. We report the case of a 52-year-old woman with an extranodal marginal cell lymphoma of her submandibular gland, whose primary presenting symptom was a slow swelling of her neck. Fine-needle aspiration of the mass was performed, followed by CT imaging studies, and both tests showed inconclusive results. The tumor was excised and the patient has been monitored with no recurrence to date. This case adds to the diverse differential diagnoses of primary tumors in the head and neck, as early consideration, identification, and management of this etiology is essential for the clinician to ensure the best patient outcomes.
