Jejunal perforation from metastatic choriocarcinoma. Case report and review of the literature

Choriocarcinoma is a rare malignant genital tract tumor, arising in the uterus or in the testis. Primary or metastatic choriocarcinomas of the gastrointestinal tract are infrequent. We report a case of a testis choriocarcinoma presenting as jejunal metastasis with perforation. Histology revealed the origin of this metastatic tumor, allowing us to recognize the primary neoplasm of the testis. A review of literature with PubMed since 1964 and of the references of the papers retrieved was performed. Since 1933 only 30 cases of jejunal choriocarcinomas have been described in literature. In 13 cases jejunal choriocarcinoma presented gastrointestinal hemorrhage, in 4 intestinal intussusception and in 1 case upper abdominal pain and vomiting. Only 5 cases of jejunal perforation have been described. The case presented is the first in literature of jejunal perforation from a metastatic choriocarcinoma of the testis.
