Metástasis cutáneas de cáncer de recto / Cutaneous metastases from rectal cancer

El carcinoma colorrectal es un tumor que con muy poca frecuencia origina metástasis cutáneas, y cuando lo hace raramente es por vía hematógena. Presentamos el caso de un varón de 55 años diagnosticado de un adenocarcinoma de recto (tercio inferior) estadioT3N2M0. Tratado inicialmente con radioquimioterapia neoadyuvante, fue intervenido ocho semanas después realizándose una amputación abdominoperineal extendida. El resultado anatomopatológico fue de adenocarcinoma mucinoso de recto, estadio ypT3bN1. Tras un postoperatorio sin complicaciones el paciente recibió tratamiento quimioterápico con capecitabina. A los 18 meses el paciente refirió la aparición progresiva de nódulos subcutáneos en distintas localizaciones. En la tomografía computarizada de control se objetivaron múltiples imágenes sugestivas de metástasis a nivel hepático y pulmonar, así como lesiones subcutáneas. La exéresis-biopsia de uno de los nódulos subcutáneos corroboró la sospecha de metástasis de adenocarcinoma de recto. Se valoró tratamiento quimioterápico que no llegó a administrarse por el rápido deterioro del paciente que llevó al exitus (AU)

Colorectal carcinoma is a tumour that very infrequently gives rise to cutaneous metastases and when it does so, it is rarely by the haematogenous route. We present the case of a 55-year old male diagnosed with anadenocarcinoma of the rectum (lower third), clinical stageT3N2M0. Initially treated with neoadjuvant radiochemotherapy, he was operated on eight weeks later, with an extended abdominoperineal amputation. The anatomopathological result was mucinous adenocarcinoma of the rectum, clinical stage ypT3bN1. Following a postoperative period without complications, the patient received chemotherapeutic treatment with capecitabine. Eighteen months later the patient reported the progressive appearance of subcutaneous nodules in different localizations. In the computerized tomography test multiple images were objectivized suggesting metastasis at the hepatic and pulmonary levels, as well as subcutaneous lesions. The biopsy-excision of one of the subcutaneous nodules corroborated the suspicion of metastasis of the adenocarcinoma of the rectum. Chemotherapy treatment was considered for the patient, which was not administered due to the rapid deterioration of the patient leading to his death (AU)
