Uterine choriocarcinoma is a rare trophoblastic tumor, characterized by its metastatic potentiality and its sensitivity to chemotherapy. Pulmonary metastases are frequent, but they rarely reveal the disease. We report the case of a 30-year-old patient with uterine choriocarcinoma. The disease occurred after a normal delivery and was revealed by a pulmonary metastasis. Through of this case and a review of literature, we remind of the diagnostic and prognostic particularities of uterine choriocarcinoma.
