title: A case of primary plasmacytoma of lymph nodes.
abstract: Extramedullary plasmacytoma may originate in any organ, either as a primary tumor or as a facet of systemic multiple myeloma. These solid lesions most commonly affect the upper respiratory tract, gastrointestinal and urogenital tract, skin, and lung. Primary plasmacytoma of the lymph node is a rare hematologic neoplasm, which usually manifests as an enlargement of the cervical lymph nodes with no evidence of any other plasma cell dyscrasia. A 56-year-old man was admitted, due to the presence of multiple palpable masses in the right cervical and submandibular areas. Surgical resection revealed plasmacytoma of the lymph nodes. According to our full work-up, no evidence of the systemic involvement of plasma cell dyscrasia was discovered and thus, the diagnosis of primary plasmacytoma of the lymph node was made. Radiotherapy was administered, and the remnant mass was reduced substantially, to 1x2 cm in size. The patient was scheduled to be monitored by a PET CT scan, as well as by a neck CT scan.
