Liposarcomas are the most prevalent soft tissue sarcomas in adults. Low-grade liposarcomas are the most frequent and least aggressive and are noted as having a low risk of metastasis. We present a case of low-grade myxoid liposarcoma that metastasized to the small bowel resulting in intussusception. This case involves a 44-year-old woman with a recurrent retroperitoneal liposarcoma. Approximately 30 months after initial diagnosis, the patient was found to have a solitary metastasis to the small bowel that presented as a jejunal intussusception. Interestingly, there was no indication of a round cell component in either the metastasis or recurrent tumor, although the original tumor did contain a small round cell component. This is the first report in the English literature of liposarcoma metastasizing to the small bowel. We suggest that atypical presentations of liposarcoma metastases should always be considered in the management of patients with a history of liposarcoma.

    Introduction: Intussusception is an uncommon cause of intestinal obstruction in adults. It usually presents with typical features of intestinal obstruction, and is associated with the presence of a 'lead point' for the invaginated portion. This 'lead point' is rarely an intraluminal, submucosal...

    Lipoma is a common soft-tissue tumor. There are only very few reported cases of intraosseous lipoma of the jaws in the literature. Intraosseous angiolipomas are even rarer. The exact nature of these lesions is debatable, but it is widely accepted that they represent true benign tumors. These are...
