Vascular tumors arising in port-wine stains: two cases of pyogenic granuloma and a case of acquired tufted angioma.
Three female patients affected by intradermal vascular tumors were presented. The lesions were acquired and developed from preexisting port-wine stains (PWS). Among the three patients observed, two had a pyogenic granuloma (PG) and the third patients had tufted angiomas. As reported earlier, formation of a PG within the lesion of a PWS supports the assumption that arteriovenous anastomoses are associated with its pathogenesis. Occurrence of tufted angioma from a PWS, as well as coexisting but separate PWS has been reported. However, the tufted angiomas of our patient were located in different sites, one in the PWS and others separate from the PWS. This has never previously been reported.
