Ovarian Extravascular Papillary Endothelial Hyperplasia (Masson Tumor) Mimicking a Primary Gynecologic Malignancy

We describe the first 2 cases of this extravascular type to occur within the ovary, one of which mimicked malignancy radiologically.

The prognosis is generally good, with complete surgical resection usually representing adequate treatment.
