Kuttner’s Tumor of Bilateral Submandibular And Parotid Glands

Chronic sclerosing sialadenitis, known as KT, was first described in 1896 by Kuttner. KT is clinically characterised by a firm mass of submandibular gland in middle-aged adults. This is an uncommon tumor-like lesion that typically involves one of the submandibular glands [1-3]. The treatment of choice is complete removal of the affected gland. The definitive diagnosis is made by histopathological examination. Histologically, KT is characterized by lymphoid follicle, acinar atropy, periductal fibrosis and dilated ducts. it is a benign and relatively uncommon condition. Therefore, it may be a little difficult for a pathologists to distinguish KT from other forms of sialadenitis. Multiglandular involvement of KT rarely occurs and it might be a manifestation of IgG4-related systemic sclerosing disease [4,5]. We experienced a rare case of KT that presents with a time-serial involvement of the bilateral submandibular and parotid glands. This report described the histological, clinical features and management of this patient. We aimed to raise awareness among otolaryngologists and pathologists about a not well-known and under-recognized entity.
