The patient had a 22-month history of amenorrhea since her last pregnancy, and a dilation and curettage procedure was performed after a 3.1×2.4×2.8 cm endometrial echogenic lesion was visualized on a pelvic ultrasound. When the diagnosis of placental site trophoblastic tumor was made by histopathologic and immunohistochemical analysis, complementary examinations including including pelvic magnetic resonance imaging (MRI) and a chest computed tomography (CT) were done. There was no evidence of disease outside the uterus, and a laparoscopic hysterectomy with bilateral salpingectomy was performed. After a surveillance period of 12 months, no disease recurrence was identified. Best imaging studies, treatment options, and proper surveillance for these type of tumors are discussed alongside the case study.
