[The appearance of pathognostic inclusion bodies in verruca vulgaris (author's transl)].

Pathognostic inclusion bodies develop in the nucleus. They frequently occur in the upper layers of the pathologically changed stratum spinosum. They are stained in an amphophilic or basophilic manner. Their structure is a nearly homogenous, finely grained or plaquelike one. The inclusion bodies contain masses of human wart viruses in a cristalline-like arrangement or are irregularily distributed. Feulgen staining is positive. Different pictures of inclusion bodies are demonstrated in paraffin sections. The knowledge of structural variants is very helpful in biopsy diagnosis of veruca vulgaris.
