Delayed diagnosis of early-stage placental site trophoblastic tumor: a case report and literature review

Backgroud Placental site trophoblastic tumor (PSTT) is a rare form of gestational trophoblastic disease without typical presentations. The objective of this report is to present a case of PSTT with massive hemorrhage. The diagnosis of PSTT was delayed and ultimately confirmed by the pathology after uterine artery embolization combined with hysteroscopically guided lesion electrosection. Case report This case reports a delayed diagnosis of PSTT with severe uterine bleeding. It is difficult to make a clinical diagnosis of PSTT at an early stage. The case provides the ultrasound, MRI, hysteroscopic, and pathologic findings of PSTT, highlights the value of uterine artery embolization combined with hysteroscope in the diagnosis of this rare condition. Conclusion: Most patients of PSTT present with nonspecific symptoms and signs at diagnosis. Occasionally they will experience badly uterine bleeding. Uterine artery embolization followed by operative hysteroscopy plays a vital role in identifying the rare and ambiguous condition.
