| Popis: | A non-invasive example of hidroacanthoma simplex that contained focal cellular atypia and abnormal mitoses occurred on the leg of an 80-year-old man. Ultrastructural features included abundant glycogen, peripheral tonofilaments and sparse short desmosomes. Nuclear profiles were smooth and nucleoli were dense and round. Thus, tumor cells were easily distinguished from the surrounding keratinocytes with which they formed short desmosomal junctions. |
