Atypical cellular chorangioma.
We describe an unusual, large atypical cellular chorangioma with abundant mitoses and focal necrosis. Other than premature birth, the prenatal and postpartum clinical course was unremarkable for both the mother and baby. Our case and a few similar cases reported in literature suggest that atypical cellular chorangioma is a benign tumor, despite its worrisome histopathologic features.
