Small intestine and ovarian metastasis in a patient with a history of cardiac fibrosacoma.

Metastatic tumors involving the small bowel are much more common than primary neoplasms. The most common metastases to the small intestine are those arising from other intra-abdominal organs. Metastases from extra-abdominal tumors are rare but may be found in patients with adenocarcinoma of the breast and carcinoma of the lung. Cutaneous melanoma is the most common extra-abdominal source involving the small intestine, with involvement of the small intestine noted in more than half of the patients dying from malignant melanoma [1]. While intestinal metastasis from sarcoma has been described, this is an extremely rare occurrence especially from a rare malignant sarcoma of cardiac origin. The dismal prognosis of cardiac sarcomas results from extensive local invasion at presentation or distant metastasis. Metastasis to the small bowel may cause obstruction, bleeding, or intussusception in which the diagnosis may be delayed because of rarity of the condition and mild and vague abdominal symptoms at early presentation. In this report, a 35 year old woman a known case of cardiac fibrosarcoma was admitted to the emergency ward with abdominal pain and distention, bloody diarrhea, and recurrent nausea and vomiting. Jejuno-jejunal invagination was diagnosed at laparotomy along with tumoral involvement of the left ovary. Histopathological study showed that there was a fibrosarcoma compatible with the earlier diagnosis of primary cardiac tumor. We have described some aspects of diagnosis and treatment of this rare cause of intestinal intussusception.
