Intravascular papillary endothelial hyperplasia of the vulva: report of a patient with Masson tumor of the vulva and literature review.

CONCLUSION: Intravascular papillary endothelial hyperplasia -- also known as Masson tumor -- is a rare, benign vascular eruption. Cutaneous lesions typically present as red colored or blue-black colored nodules ranging in size from 0.25 to 5 centimeters in diameter. The most common sites of presentation include the head, neck, and extremities. However, albeit rarely, lesions may also appear in the genital region. The histologic hallmark of intravascular papillary endothelial hyperplasia is an organizing thrombus in the vascular lumen with associated hyperplastic endothelial cell proliferation. Lesions often appears similar to other neoplastic and non-neoplastic cutaneous tumors, including hemangiomas, pyogenic granulomas, and cutaneous angiosarcomas. Therefore, pathologic examination is required to confirm the suspected diagnosis and exclude malignancy. The condition can usually be treated with simple local excision.
