Verruciform xanthoma in association with a vulval fibroepithelial polyp.

We report the clinical, light microscopic, immunohistochemical and ultrastructural features of a verruciform xanthoma that developed in association with a vulval fibroepithelial polyp. To our knowledge, this is the first time that this association has been reported. Immunohistochemical findings confirmed that the xanthoma cells were of a monocyte/macrophage lineage. In addition to typical histological characteristics, prominent vascular ectasias were detected in the deep dermis at the periphery of this lesion. The ectasias may play a part in pathogenesis.
