Resumen
Introducción: el sarcoma fibromixoide de bajo grado (LGFMS) se considera un tumor de tejidos blandos raro, que tiene tendencia a surgir del tronco y de las extremidades inferiores, su localización en el área intraabdominal se considera poco común.
Objetivo: describir un caso de LGFMS primario de colon transverso perforado con metástasis hepática.
Caso clínico: describimos el caso de un paciente masculino de 57 años con dolor abdominal de inicio súbito; en la cirugía se encontró un tumor con absceso y perforación en el colon transverso que infiltraba hasta la raíz del mesenterio. Se realizó hemicolectomía izquierda extendida con colostomía de colon ascendente. Más tarde, en una exploración posoperatoria, se encontró que tenía enfermedad hepática metastásica.
Conclusiones: este caso es único en términos de ubicación y presentación. Es un recordatorio del diagnóstico diferencial del dolor abdominal agudo. Hasta donde sabemos, es el primer caso de LGFMS del colon con metástasis hepática sincrónica.
Abstract
Background: Low grade fibromyxoid sarcoma (LGFMS) is considered a rare soft tissue tumor and has a tendency to arise from deep soft tissue of the trunk and lower extremities, the intraabdominal area is considered a rare location.
Objective: To describe the first case of a LGFMS arising from the transverse colon with liver metastasis.
Clinical case: We describe a 57-years-old male patient with abdominal pain of sudden onset; at surgery he was found to have an abscessed tumor in the transverse colon that infiltrated to mesentery root. An extended left hemicolectomy was performed with ascending colon colostomy. Later on, a postoperative scan he was found to have metastatic liver disease.
Conclusions: This case is unique in terms of the location and presentation. It’s a reminder of differential diagnosis of acute abdominal pain. To our knowledge is the first case of a LGFMS of the colon with synchronous liver metastasis.
