Abstract
We report a rare case of inflammatory pseudotumor arising in the left submandibular gland. A 74-year-old man underwent selective neck dissection for a left submandibular gland mass. Imprint cytological examination of the specimen revealed numerous lymphocytes, plasma cells and myofibroblastic cells. Histopathology showed fibroblastic spindle cells with numerous mature plasma cells arranged in poorly formed fascicles and in a vaguely storiform pattern. The lesion mass was diagnosed as an inflammatory pseudotumor. Thus, diagnosis could be hypothesized from the cytological findings alone.
