ABSTRACT
<p><b>OBJECTIVE</b>To investigate the clinicopathological characteristics, diagnostic criteria and differential diagnosis of placental chorioangioma.</p><p><b>METHODS</b>Twenty-five cases of placental chorioangioma were analyzed for their clinical data, histomorphology and immumohisto chemical staining. Relevant literature was reviewed.</p><p><b>RESULTS</b>The average age of the 25 patients was 29 years. Fourteen patients had full-term pregnancy, 10 had preterm labor, and 1 had intrauterine fetal death. Nineteen patients had pregnancy complications. The tumors presented as red or dusty pink nodules with clear borders. The tumor size ranged from 1 to 16 cm. Microscopically, the tumors possessed abundant capillaries or cavernous blood spaces lined by hyperplastic endothelial cells. These cells were positive for CD34 and Ki-67 index < 10%.</p><p><b>CONCLUSIONS</b>Placental chorioangioma is a rare benign tumor of the placenta, and is associated with various pregnancy complications. Misdiagnosis of cell-rich type tumor should be avoided.</p>
