[In vivo stereomicroscopy of various cutaneous lesions]

"In vivo" morphological characteristics of some cutaneous lesions predominantly pigmented, examined under a stereoscopic microscope are described. An unusual analysis of the surface and the interior (when possible) of 590 lesions which are not able to be examined by the simple clinical observation was made. This method allowed to carry out a right and opportune treatment. A biopsy and histological study of 424 lesions of the total number examined was made. Stereomicroscopic and histological comparative diagnoses allowed to abtain 87.2% accuracy with the former before the practice of biopsy. The clinical diagnosis was improved in 17.2% when utilizing the stereoscopic microscope instead of the one suggested by the naked-eye inspection.
