Small Bowel Leiomyosarcoma – a case report

Abstract

Leiomyosarcomas (LMS) are rare mesenchymal tumours. LMS of the small bowel originate from smooth muscle cells from muscularis propria, with a peak of incidence around 60 years of age, without characteristic clinical signs, being, most of the time, detected when studying the cause of an occult haemorrhage or intestinal occlusion, with findings in CT scan or US.

We report a case of a female patient, of 53 years of age, brought at our assistance with complaints of hipogastric discomfort, with a palpable mass in hipogastro and umbilical region, and that after performing an abdominal CT scan, was disclosed a mass, with 12 cm, appearing to have involvement of jejunal loops.

In surgery, a jejunal mass, with extra-luminal growth was disclosed and excised, whose histology identified as being a Leiomyosarcoma. With a 24 month of follow-up, there is no recurrence.
