[Comparison of the epidermodysplasia verruciformis Lewandowsky-Lutz with the other Papova virus acanthomas by light and electron microscopy (author's transl)].
Based on histology and electron microscopy, a series of Papova virus acanthomas consisting of 300 common warts and Condylomata acuminata as well as primary efflorescences of 7 typical and 7 questionable cases of Epidermodysplasia verruciformis have been classified. Four cytological types expressing different cytopathogenic viral actions were established. Typ 4 ("basophilic foamy giant keratinocytes") seems to be specific for Epidermodysplasia verruciformis which thus can be differentiated histologically against ordinary warts (type 1-3).
Condylomata Acuminata↗
