RESUMO
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.

Los ameloblastomas son tumores odontogénicos benignos localmente agresivos que entre un 15-20 por ciento se localizan en el maxilar superior. Éstos tienen peor pronóstico que sus homólogos mandibulares al presentar mayor índice de recidivas postquirúrgicas y un mayor porcentaje de malignización. Su proximidad a fosas nasales, órbita y base de cráneo les hace presentar un riesgo añadido por la probabilidad de extensión a estas estructuras (AU)
The ameloblastomas are benign odontogenic tumors locally aggressive that between 15-20% are located in the upper maxillary. The maxillary ameloblastomas have worse forecast than their mandibular homologous upon presenting greater index of postsurgery relapses and a greater percentage of malignancy. Their proximity to nasal cavity, orbit and skull base suppose a risk added by the probability of extension to these structures (AU)
