Abstract

The lymphomas of mucosa-associated lymphoid tissue (MALT), are uncommon entities, of low grade of malignancy with very infrequent or no lymph node involvement. They represent about 80% of the primary pulmonary lymphomas. The synchronous appearance with lung adenocarcinoma is an extremely rare finding. We present the case of an ex-smoker 68-year-old man, in whom, in the follow-up of a pulmonary nodule, a second pulmonary nodule was found. The surgical biopsy confirmed the diagnosis of both neoplasms.

Los linfomas derivados del tejido linfoide asociado a las mucosas (MALT) son entidades poco frecuentes, de bajo grado de malignidad con escaso o nulo compromiso ganglionar y representan cerca del 80% de los linfomas primarios pulmonares. La aparición sincrónica con adenocarcinoma de pulmón es un hallazgo extremadamente infrecuente. Presentamos el caso de un hombre de 68 años, ex-tabaquista, en quien durante el seguimiento de un nódulo pulmonar se identificó un segundo nódulo y la biopsia quirúrgica confirmó el diagnóstico de ambas neoplasias.

Keywords: MALT lymphoma; lung adenocarcinoma; primary lung lymphoma; synchronous lung tumors.
