XXXX originating from the mesorectum: a case report.

@entity5 @entity1 @entity242 @entity1418
BACKGROUND: @entity1418 ( @entity1418 ) is a common @entity242 affecting soft tissues of the body, especially of the extremities or trunk. Prognosis of the abdominal @entity1418 is usually poor. CASE PRESENTATION: A 52-year-old female presented to our surgical outpatient clinic with a lower @entity5 that had been gradually increasing in size. Clinical examination revealed a firm, irregularly surfaced, fixed, painless, @entity1 -head-sized @entity5 located in her lower abdomen. Computed tomography (CT) and magnetic resonance imaging (MRI) of the abdomen revealed a @entity5 at the lower abdomen which was 15   13   11 cm in diameter and encased the colorectum to the left back side. A barium enema and a colonoscopy showed direct invasion to the rectum. In 2001, the @entity5 had been excised along with a low anterior resection of the rectum because of direct invasion. The origin of this @entity5 was the mesorectum. The weight of the excised @entity5 was 1,500 g, including 800 ml of a brown fluid. A histopathological diagnosis revealed a common type of @entity1418 , in which mitotic figures are frequently seen. CONCLUSION: This @entity1 has survived without recurrence, for approximately 8 years since the completed @entity5 resection. It is important to obtain a complete resection during the @entity1418 treatment.
