Mandibular solitary plasmocytoma of the jaw: A case report

ABSTRACT

Plasma cell tumors are lymphoid neoplasms with an uncontrolled proliferation of B cells. These are divided intolocalized forms (solitary bone plasmocytoma -SBP- and extramedullary plasmocytoma -EP-) and disseminatedforms (multiple myeloma–MM-). The SBP is a rare and controversial disease. The aim of this article is the analysisof this entity based on the presentation of a 64-year-old man without previous medical history, with a mass in theleft mandibular angle extending to the parotid region on the same side. The panoramic radiography, computedtomography and magnetic resonance imaging showed an osteolytic lesion 6.5 x 5 x 6.7 cm in the mandibularangle with infiltration of the masticator space and left parotid region. The normality of the extension study, andhistopathological examination confirmed the diagnosis of SBP. The patient received treatment with radiotherapywith good outcome (AU)
