Chorangiomas are rather frequent neoplasms encountered on placental examination but in rare cases they present some worrisome histological features that could alarm the pathologist and be misinterpreted as a malignant neoplasm, even if their biological behavior is favorable. We describe an unusual chorangioma with high cellularity and abundant mitosis that, after careful examination and postpartum follow-up, showed benign clinical course for mother and child confirming previous reported cases. This type of tumor is known in the literature as atypical cellular chorangioma and its identification is important in order to exclude potentially dangerous overtreatment.

Abstract
Chorangiomas are rather frequent neoplasms encountered on placental examination but in rare cases they present some worrisome histological features that could alarm the pathologist and be misinterpreted as a malignant neoplasm, even if their biological behavior is favorable. We describe an unusual chorangioma with high cellularity and abundant mitosis that, after careful examination and postpartum follow-up, showed benign clinical course for mother and child confirming previous reported cases. This type of tumor is known in the literature as atypical cellular chorangioma and its identification is important in order to exclude potentially dangerous overtreatment.
