Case report about a 45 year old man with hyperkeratotic papules and plaques on both lower legs now persisting for more than 20 years. After detection of arterio-venous shunts the initial clinical and histological diagnosis of Kaposi-sarcoma had to be replaced by the diagnosis of pseudo-Kaposi's sarcoma, a benign reactive process. In the pathogenesis of this disease arteriovenous shunts are of great importance.
A 17-year-old girl is reported with a history of recurrent febrile episodes during her menstrual bleeding accompanied by a generalised exanthem. Increased plasma levels of unbound etiocholanolone were noticed during the febrile attacks. Both the fever and the skin eruption could be suppressed by oral contraceptives.
In cases of varicocele the reverse venous blood flow can be detected by the use of the Doppler-stethoscope in a simple way. Applied to the basic examination of fertility patients this method has proved to be a valuable non-invasive screening in the evaluation of varicoceles including cases with minor clinical symptoms. According to our results, "subclinical varicocele" as a entity of venous diseases shows special clinical features. Varicocele-orchiopathy is caused by the reverse venous blood flow, when peritesticular venous anastomoses and crosses are less developed or insufficient in their compensatory function.
