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 into localized forms (solitary bone plasmocytoma -SBP-and extramedullary plasmocytoma -EP-) and disseminated forms (multiple myeloma-MM-). The SBP is a rare and controversial disease. The aim of this article is the analysis of this entity based on the presentation of a 64-year-old man without previous medical history, with a mass in the left mandibular angle extending to the parotid region on the same side. The panoramic radiography, computed tomography and magnetic resonance imaging showed an osteolytic lesion 6.5 x 5 x 6.7 cm in the mandibular angle with infiltration of the masticator space and left parotid region. The normality of the extension study, and histopathological examination confirmed the diagnosis of SBP. The patient received treatment with radiotherapy with good outcome.

Osseous Plasma Cell Neoplasm of the Mandible for Initial Diagnosis of Multiple Myeloma: Case Report and Literature Review

“…Especially misdiagnoses as ameloblastoma, odontogenic or malignant tumor of inflammatory disease are common [4]. The patient in our case was female and in the eighth decade of life, neither gender nor age were typical for the occurrence of MM [4,14]. The size of the primary lesion as well as the systemic manifestations may hypothesize an initial delay in diagnosis.…”

Solitary plasmacytoma of the mandible: report of two cases

“…There are three different groups according to their dysplasia: dysplasia at low level (plasmablastos lower than 10%), dysplasia at middle level (plasmablastos between 10% and 50%) and severe dysplasia having the worst prognosis with more than 50% in an immature form 2. Our cases may be classified as middle level, as approximately 40% dysplasia was seen.…”
