Abstract
This article presents the case of a 43-year-old male patient with recurrent painful swelling of the right submandibular gland. Submandibulectomy was performed. Histological investigations showed an intense granulomatous inflammation with severe destruction of the parenchyma. The inflammatory infiltrate consisted of abscesses with neutrophilic and eosinophilic granulocytes and ill-defined granulomas with multinucleated giant cells. Some of the blood vessels showed evidence of vasculitis. After further clinical and serological investigations with highly elevated levels of cytoplasmic antineutrophil cytoplasmic antibodies (c-ANCA) and antiproteinase-3 antibodies, a rare limited disease of granulomatous polyangiitis (Wegener granulomatosis) was finally diagnosed. Such a manifestation of the disease is exceedingly rare; therefore, only single case reports have so far been described. The certain establishment of the diagnosis seems to be challenging because of the lack of involvement of the respiratory tract and the kidneys. In this case a histological assessment and clinical findings are mandatory for the correct diagnosis.
