Tumor trofoblástico del lecho placentario

Placental-site trophoblastic tumor is exceptionally uncommon, with no more than a hundred cases reported in the literature. It is a neoplastic disorder of the middle trophoblast, with metastatic potential in a few cases. Our patient was a 30-year-old woman with amenorrhea of 10 weeks and 4 days' duration who attended the maternity emergency service complaining of vaginal bleeding. Physical examination, laboratory tests and ultrasonographic findings were compatible with a diagnosis of trophoblastic disease. After several curettages, this rare histopathological diagnosis was made. The tumor recurred and negative tumoral extension study and simple hysterectomy were performed. Analysis of the surgical specimen confirmed the diagnosis of placental-site trophoblastic tumor. After 1 year, laboratory tests show no recurrence and the patient is clinically disease-free.
