[Jejunal metastasis from choriocarcinoma. A three-case report].

Five per cent of patients presenting with choriocarcinoma develop small bowel metastasis. Tumors of the small bowel are rare and the metastases are generally from lung and breast carcinoma or from melanoma. Clinical presentation is vague and the majority of cases are autopsy findings. The main symptoms are related to the presence of abdominal tumor or hemorrhage, or bowel obstruction or perforation. We present the cases of three patients with small bowel metastasis from choriocarcinoma. A 24-year-old woman with bowel obstruction secondary to intussusception caused by a metastatic choriocarcinoma polypoid mass and two men, one 18 years old and the other 24 years old, with a history of testicular tumor, who presented with gastrointestinal bleeding due to small bowel metastasis from choriocarcinoma, 2 and 10 months after orchiectomy, respectively. Management was endoscopic in one case and surgical in the other two. Two patients died in the early postoperative period and one patient died during the first year of follow-up. Choriocarcinoma metastases are very rare and their main clinical manifestations are hemorrhage and bowel obstruction. Management can be either medical or surgical. The majority of patients with choriocarcinoma respond to chemotherapy but prognosis is worse for those patients presenting with small bowel metastasis.
