[The differential diagnosis of lymphogranulomatosis (Hodgkin's disease) and sialoadenitis of the submandibular salivary gland].

A case of Hodgkin's disease with local involvement of the submandibular area is described. Profound examinations found that the tumor did not originate from the salivary gland. Anatomic examination of the resected tumor revealed Hodgkin's diseases. The authors emphasize the necessity of differential diagnosis between Hodgkin's disease and chronic sialadenitis.
