Pemphigus vulgaire et maladie de Kaposi

Abstract
The occurrence of a Kaposi sarcoma [in a patient] during the course of a therapy for a pemphigus vulgaris is reported. Only 5 such associations have been previously described in the literature. On the other hand, several works have reported simultaneous occurrence of a Kaposi sarcoma with anomalies of the immune or lymphoid systems (lymphoma, Hodgkin disease, Waldenstrom disease, mycosis fongoides). A hypothesis concerning the Kaposi sarcoma genesis can be suggested on the basis of these observations and remains to be confirmed.
