El linfoma pulmonar primario es una entidad poco fre-cuente, que en la mayoría de las ocasiones es de estirpe celu-lar tipo B, predominantemente de bajo grado y de tejido lin-foide asociado a la mucosa (MALT/BALT). Los linfomas pulmonares primarios de alto grado suelen presentarse en pacientes inmunodeprimidos. Habitualmente se presentan con síntomas respiratorios y generales. La radiografía de tó-rax puede mostrar una masa pulmonar o atelectasia y de-rrame pleural. El pronóstico es peor que en los linfomas pulmonares de bajo grado, con un tiempo de supervivencia de 8-10 años y una mayor probabilidad de progresión local o recidiva a distancia. Presentamos el caso de un paciente de 76 años no inmunodeprimido con una masa pulmonar cavi-tada secundaria a un linfoma pulmonar primario tipo B de células grandes. Después de la cuarta sesión de quimiotera-pia se objetivó una reducción de la masa pulmonar y en la cavidad residual se desarrolló un aspergiloma. Revisando la bibliografía se ha comprobado lo anecdótico del caso pre-sentado, pues es extremadamente poco frecuente que un lin-foma pulmonar primario se presente en forma de masa cavi-tada única y con poca repercusión clínica en cuanto a sintomatología general.

Primary pulmonary lymphoma is a rare entity usually formed of B-type cells, usually low-grade and composed of mucosal- or bronchial-associated lymphoid tissue. High-grade primary pulmonary lymphomas usually occur in immuno-deficient patients who mostly present with respiratory and nonspecific symptoms. A chest x-ray may show a pulmonary mass or atelectasis and pleural effusion. In such cases, the prognosis is worse than for low-grade pulmonary lympho-mas; survival is 8 to 10 years and there is a higher probabi-lity of local progression or metastasis. We report the case of an immunocompetent 76-year-old patient who had a pulmo-nary mass with cavitation secondary to a large B-cell pri mary pulmonary lymphoma. After the fourth session of chemo therapy the pulmonary mass was reduced in size and an aspergilloma was seen to have developed in the residual cavity. A review of the literature revealed this case to be anecdotal as it is ex-tremely infrequent for a primary pulmonary lymphoma to present in the form of a single mass with cavitation and with few symptoms.
