RESUMEN
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.

A case of invasive aspergillosis of the maxillary sinus in an immunocompromised patient is presented. Aspergillosis of the paranasal sinuses is uncommon, however, its incidence has shown a marked increase in number in the recent years. It has been classified into four types: allergic, noninvasive, invasive and fulminant. Immunocompromised patients are particularly at the risk of fulminant invasive aspergillosis. Early diagnosis is essential in order to avoid the high morbidity and mortality associated with the destructive disease and to instigate treatment before irreversible conditions arise.

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.

Presentamos el caso clínico de un varón de 63 años con fístula cutánea en la región parotídea izquierda secundaria a un cálculo intraparotídeo de gran tamaño. Los cálculos salivares son más frecuentes en la glándula submaxilar, y en su mayoría son de pequeño tamaño; la presencia de una fístula cutánea en su diagnóstico y tratamiento de la litiasis parotídea (AU)
