Chronic sclerosing sialadenitis (Kuttner tumour): clinical case report

Jornal Brasileiro de Patologia e Medicina Laboratorial 10/2007; 43(5):381-384. DOI: 10.1590/S1676-24442007000500012

ABSTRACT Chronic sclerosing sialadenitis (Kuttner tumour) is an unusual chronic inflammatory process of the salivary gland that affects principally the submandibular gland. The aim of this work is to report a case of chronic sclerosing sialadenits associated with sialolithiasis. Kuttner tumour is an uncommon entity that clinically may not be distinguished from neoplasia and though it can be resolved by surgical excision of the lesion, it causes important upset for the patient, as intense pain, dysphonia and dysphagia.

    ABSTRACT: Patients with Kuttner tumours present with clinical features simulating a submandibular tumour. This article aims to familiarise sonologists with the sonographic appearances of these tumours, to help in their differentiation from other salivary lesions. In 13 patients with histologically or cytologically proven Kuttner tumours, the features evaluated on sonography included: shape and border of the gland, internal architecture, duct dilatation, presence/absence of calculi and presence and distribution of vascularity. There was diffuse involvement of the submandibular glands in 11 patients and focal involvement in 2. The majority (9 of 11) of the patients with diffuse involvement showed sonographic appearances simulating a "cirrhotic" liver; 2 showed diffuse heterogeneous involvement with duct dilatation and calculus. Doppler showed prominent intraglandular vessels, with no evidence of displacement. Focal lesions (2 of 11) were seen as hypoechoic, heterogeneous "masses," with a radial branching vascular pattern within, on Doppler. In conclusion, sonographic features may help in identifying Kuttner tumours of the submandibular glands.
