Giant placental chorioangioma: A rare case report.
Int J Surg Case Rep
September 2024
Department of Pathology, Faculty of Medicine, Hormozgan University of Medical Sciences, Bandar Abbas, Iran.
Article Synopsis
- Chorioangioma is a benign, rare vascular tumor of the placenta with an incidence of about 1%, and giant chorioangiomas can lead to various pregnancy complications.
- A case study involved a 34-year-old woman with a twin pregnancy, where ultrasounds revealed one fetus with growth issues and a 5.8 cm chorioangioma on the placenta; a cesarean delivery was performed, resulting in two healthy neonates.
- Chorioangioma's pathogenesis is unclear, but it’s notably associated with multiple pregnancies, gestational diabetes, and maternal hypertension; prenatal ultrasounds are effective for diagnosis, differentiating it from malignant tumors like chorioangiocarcinoma.

A 77-year-old male presented with recurrent diarrhea for more than 2 years, aggravated and a 1-month history of a rectal mass. High-definition white light colonoscopy showed an approximately circumferential elevated lesion from about 12 cm from the anus to the dentate line, with surface nodules of different sizes, some surfaces slightly congested, and internal hemorrhoids. The patient was diagnosed with a giant laterally spreading tumor-granular nodular mixed type (LST-G-M) of the rectum with the possibility of local malignant transformation and treated with single-tunnel assisted endoscopic submucosal dissection (ESD) at the patient's request.
