“…The most important factor to impact overall survival and disease-free survival is clear surgical margins. In addition, histologic type and tumor size are important predictors of survival in patients with retroperitoneal soft tissue sarcoma [26] . Tseng et al [27] reported that on multivariate analysis, well-differentiated tumors, like in our case, are associated with better survival with statistically significant difference.…”

“…[1][2][3] A leiomyosarcoma is a rare malignancy arising from the smooth muscles, mostly encountered in the retroperitoneal space, vascular wall, and soft tissues of the lower extremities. 4 GISTs are the most common of the malignant mesenchymal tumours, while these tumours, a type of non-GIST sarcomas, are rare tumours that occur anywhere in the gastrointestinal tract, though mostly described in the stomach and small bowel. Among gastrointestinal malignancies, these constitute a rare subset, and mostly occur in the ileum.…”

Duodenal leiomyosarcoma: a rare entity

Tumours of the small intestine are among the rarer conditions as compared to other tumours of the gastrointestinal tract. Among these, sarcomas hold a much lesser number in proportion to adenocarcinomas. Leiomyosarcomas occurring in the small intestine constitute an even smaller number, accounting for about 1% of malignant mesenchymal lesions in the gastrointestinal tract. Within the spectrum of LMS of the small intestine, the more common location encountered is the ileum, followed by the duodenum. The second part of the duodenum is usually implicated in most studied and reported cases of duodenal LMS. These tumours are known for their aggressive nature and their often-delayed presentation due to ill- defined symptomatology and diagnostic challenges. As a result of the above, even a century after the first reported case, their prognosis is poor. Here we report a case of a 64-year-old female who presented with vague complaints of abdominal discomfort and dyspepsia for a month and was diagnosed to have a mass lesion in the 2nd and 3rd part of the duodenum. Intraoperatively, she was found to have two separate mass lesions in D1 and D3 and was subjected to a pancreaticoduodenectomy. The mass lesions were pathologically categorized as leiomyosarcomas of the first and third part of the duodenum.

Leiomyosarcoma is a subtype of soft-tissue sarcoma, which is a rare soft-tissue malignancy comprising < 1% of adult cancers. There are a variety of etiologies of small bowel obstruction. Infrequently, small bowel malignancies can first present as small bowel obstruction. In exceedingly rare cases, leiomyosarcomas can be the offending malignancy. A 53-year-old male presented to the emergency department with several weeks of persistent right abdominal pain, nausea, and vomiting. Computed tomography scan revealed a central necrotic mass within the right lower quadrant originating from the small bowel. The patient underwent exploratory laparotomy to relieve the obstruction and a mass was identified originating from the terminal ileum that adhered to surrounding structures. Pathological analysis determined the mass to be small bowel leiomyosarcoma. Leiomyosarcoma is definitively diagnosed after primary resection with histopathology and immunohistochemistry. As opposed to other small bowel neoplasms, surgical resection with negative margins is the only potentially curative option.
