It is associated with an aggressive behavior and typically favor hematogenous spread. The current standard of care is surgical resection. A 49-year-old patient presented with a 2-month history of fever. A PET-scan revealed a hypermetabolic mass in the transverse colon, and colonoscopy confirmed a tumor. A right hemicolectomy was performed. Histopathological diagnosis was of a leiomyosarcoma. Fourteen months after the surgery, a follow-up abdominal scan revealed a 2\u2009cm mesenteric lymph node that was hypermetabolic on PET-scan. The mesenteric lymph node was resected and histopathology confirmed a leiomyosarcoma metastasis. This case opens the controversy on the management of rare lymph node recurrences in colorectal leiomyosarcoma.<\/jats:p>","DOI":"10.1155\/2020\/6935834","type":"journal-article","created":{"date-parts":[[2020,3,23]],"date-time":"2020-03-23T23:31:58Z","timestamp":1585006318000},"page":"1-5","source":"Crossref","is-referenced-by-count":3,"title":["Mesenteric
