The histological confirmation obtained with routine histopathology (Haematoxylin-Eosin staining for studying morphologic alterations and Fite-Faraco staining for demonstration of acid-fast bacilli) were 32% for early leprosy and 25% for clinically suspect leprosy. With performance of the in situ hybridization on the histologically unconfirmed cases, the positivity rates obtained were 58.8% and 55%, respectively. The results of the study confirm the utility of the procedure in the diagnostically difficult situations of early and suspect leprosy, and it is proposed that the procedure be employed in situations of clinical doubt.</p>  a0148-916X
