Angiomatoid Spitz nevus - A distinct variant of desmoplastic Spitz nevus with prominent vasculature

Five cases of a distinctive variant of desmoplastic Spitz nevus are reporte d. To the best of our knowledge, this tumor has never been described previo usly. Clinically, it presents itself as a solitary papule on the extremitie s of young adults. Microscopically, it shows predominance of solitary melan ocytes with epithelioid appearance over cell nests. They are embedded in a prominent fibrous stroma with many densely arranged, small blood vessels wi th plump endothelia not seen in other Spitz nevi. Because of its resemblanc e to a vascular tumor, the name angiomatoid Spitz nevus is proposed for thi s lesion. Absence of recurrences or metastases after complete excision in a ll cases supports the benign nature of the tumor.
