Kuttner\'s tumor is called chronic sclerosing sialadenitis is a chronic inflammatory condition affecting the salivary glands. This is relatively rare in occurrence, and more important is that it is under-recognized and under-reported. A 71-year-old male patient came to our ENT outpatient department with complaints of swelling in the right submandibular region for 2 months, which was painless and insidious in onset growing slowly to attend the present size. The patient was hypertensive and nondiabetic. On local examination, there was a swelling of size 4 cm × 4 cm confined to the right submandibular triangle. The mass was firm in consistency, nontender with irregular surface, and not fixed to the skin or underlying structures. The mass was palpable bimanually. Skin over the swelling was normal. Clinically, the patient was diagnosed as “chronic submandibular adenitis” and sent for fine needle aspiration cytology (FNAC) and ultrasonogram (USG) of the neck. FNAC came as chronic adenitis of submandibular gland (right). USG neck came as submandibular adenitis (right). So the right submandibular gland was excised under general anesthesia and sent for the histopathological study. The microscopic study reported as Kuttner\'s tumor (chronic sialadenitis with sialometaplasia). This is a rare benign condition of the submandibular gland simulating a tumor and is because of chronic inflammation. This case is presented here because of its rare occurrence.
