Recently we experienced two patients diagnosed chronic sclerosing submandibular sialadenitis. They are males 73 and 47 years of age, each with the chief complaint of swelling of the right submandibular region, and the major symptom of tenacious tumoral changes of the submandibular salivary gland.<BR>On ultrasonic examination, an image of the solid lesion with a relatively clear outline was obtained in each case. In particular, the internal echography resulted in heterogenous low echo.<BR>Sialogram disclosed irregular dilatation of the major and the peripheral ducts, as well as leakage of contrast medium into the grandular parenchyma. Especially in Case No.2, the contrast agent filling the duct was of a lower density, suggesting possible foreign matter presence.<BR>Sialoadenectomy was performed in these cases, and chronic sclerosing submandibular sialoadenitis was diagnosed by histopathology. In case No.2, a foreign matter of phytoid fibers was found in the main duct of the submandibular gland.
