CALCIFICATION IN LYMPH NODES

A 64-year-old white man came for comprehensive dental care. A panoramic radiograph demonstrated multiple well-circumscribed opacities consistent with calcifications of the parotid, superficial cervical, and submandibular lymph nodes.

Physical examination revealed multiple small, well-circumscribed, firm, fixed, and nontender masses in the preauricular, retromandibular, and submandibular regions. The differential diagnosis of lymph node calcifications includes past history of histoplasmosis, tuberculosis, BCG vaccination, coc- cidiomycosis, filariasis, and lymphoma, as well as

metastasis from osteosarcoma or other calcifying neoplasm (thyroid, colon). Lymph node calcifica- tions may also be idiopathic.

Past history proved to be negative. The patient declined further workup.
