[Mucocutaneous leishmaniasis. Histologic classification and anatomoclinical correlations. Apropos of 102 cases].

Two hundred and three skin and mucosal biopsies performed in 162 patients suffering from leishmaniasis, were studied retrospectively. They were classified according to Ridley into 5 histological groups of increasing severity. In cutaneous leishmaniasis, a high proportion of the biopsies belonged to groups III and IV. In mucocutaneous leishmaniasis, the percentage of groups III and VI was lower and group V was present in 20% of cases. In 16 patients, followed by repeated biopsies, we detected some variations of the histological group during the course of the disease. However, there were no positive correlations between clinicopathological features and prognosis.
