Tumor metastásico de colisión. Informe de un caso

Abstract

ResumenAntecedentesLos tumores de colisión son raros, se definen como la presencia de 2 tumores de diferente estirpe histológica en el mismo órgano o sitio.Caso clínicoSe presenta el caso de una paciente femenina de 71 años, con antecedente de tumor carcinoide resecado hace 20 años, sin recidiva. La paciente presenta cuadro de oclusión intestinal secundario a tumor en flanco derecho del abdomen. Se le realiza laparotomía exploradora con resección del tumor, y citorreducción óptima. En el estudio histopatológico se encuentra adenocarcinoma de ovario bilateral, así como tumor de colisión en metástasis, el cual presenta 2 estirpes histológicas: adenocarcinoma bien diferenciado y tumor mixto maligno mülleriano mesodérmico. La paciente es enviada para quimioterapia adyuvante, presentando mala evolución. Murió a los 24 meses.ConclusionesLa presencia de tumores de colisión es extremadamente rara, en la literatura no hay estadísticas ni tratamiento específico. Su diagnóstico es histopatológico. No se ha reportado ningún caso similar en la literatura médica.AbstractBackgroundCollision tumours are extremely rare. They are defined by the presence of two tumours of different histological origin in the same organ.Clinical caseA 71 year old female with history of a carcinoid tumour removed 20 years ago without any recurrence. The patient was admitted with intestinal occlusion symptoms secondary to a right flank abdominal tumour. An exploratory laparotomy was performed, removing the tumor and applying optimal debulking.The histopathological study reported bilateral ovary adenocarcinoma, as well as metastatic collision tumour of two histological types: well differentiated adenocarcinoma and a mixed malignant mesodermic Mullerian tumor.The patient was treated with adjuvant chemotherapy with poor results (death in 24 months).ConclusionsThe presence of collision tumours is extremely rare. There are no statistics or specific treatment reported. Diagnosis is made with histopathology. At the moment, no similiar cases have been reported.
