A case of multiple calcifications in the bilateral submandibular and submental lymph nodes.

We report on a patient with calcification of the bilateral submandibular and submental lymph nodes. A 40-year-old woman had swelling of the buccal gingiva around 5.Panoramic radiography at presentation showed radiopaque images, one in the right submandibular region and one in the left submandibular region. CT examination showed multiple high density masses that appeared calcified, one in the right submandibular region, two in the left submandibular region, and one in the submental region. We excised the masses from both submandibular and submental regions under general anesthesia, and found that the masses were covered with a thin fibrous tissue coat ; calcified bodies of various sizes had formed in the lymph nodes. Although foreign body giant cells were observed around the calcified bodies, there were no epithelioid cells and no Langerhans' giant cells, which are typically observed in tuberculosis. Ziehl-Neelsen stain was negative. We histopathologically diagnosed the masses as fibrosis with calcification. The clinical course has been good to date, with no recurrence 1 year 5 months postoperatively.
