[Plasmoacanthoma. A contribution to the diagnosis, etiopathogenesis and nosology].

We report on a patient suffering from plasmoacanthoma which started from the right angle of the mouth and extended to the oral mucosa. The clinical tentative diagnosis of a malignant tumor was histologically supported by an immediate frozen section under surgery. Only histological examination of tumor material embedded in paraffin settled the diagnosis of plasmoacanthoma. On the base of mycological demonstration of Candida albicans on the tumor tissue, we discuss etiopathogenetic aspects of plasmoacanthoma as well as its nosologic position.
