Linfoma pulmonar primario no Hodgkin con infiltración de miocardio / Primary pulmonary non-Hodgkin lymphoma with myocardial infiltration

RESUMEN

Se presenta un caso de linfoma pulmonar primario no Hodgkin con invasión de miocardio, evento que no ha sido previamente descrito en la literatura. Estos tumores se extienden por proximidad, habiéndose descrito invasión de pericardio, de la pared torácica y del esófago. La paciente falleció de insuficiencia cardíaca y la infiltración tumoral miocárdica fue el factor determinante por un fallo de la contractilidad miocárdica. La infiltración miocárdica se ve facilitada por el mayor volumen del tumor que infiltra la pared pleural(AU)

ABSTRACT

A case of primary pulmonary non-Hodgkin's lymphoma is presented. On this occasion, the lymphoma invaded the myocardium, an event which has not previously been reported in the literature. These neoplasms spread by proximity, and invasion of the pericardium, thoracic wall and oesophagus have been described. Our patient died from heart failure. Tumour myocardial infiltration may well have been the determinant cause through various mechanisms, including a decrease in myocardial contractility. Spread into the myocardium may be facilitated by bulky tumour infiltrates in the pleural space(AU)
