Expanding the clinicopathologic spectrum of palisaded encapsulated neuroma.

abstract：BACKGROUND:Carcinoma cuniculatum and verrucous carcinoma are both very well differentiated forms of squamous carcinoma and thus difficult to separate histologically from pseudocarcinomatous hyperplasia. The diagnosis of each often requires clinical-pathologic correlation. METHODS:We reviewed the literature on cases re...
