Tumor de colisión: Metástasis de adenocarcinoma y linfoma folicular en un mismo ganglio linfático

Resumen

Collision tumors are defined as the simultaneous presence of two
adjacent but histologically distinct tumor types arising in the same organ or site. The
occurrence of these tumors is rare. We report a 52 year-old woman with a collision tumor
consisting of metastatic adenocarcinoma and follicular lymphoma present in the same lymph
node, excised from the left supraclavicular space. The patient died four weeks after the diagnosis
was made
