Abstract:
Several reports have demonstrated difficulties and lack of agreement in the histopathological diagnosis of particular melanocytic lesions, with problems in their management. A histogenetic approach to the study of these lesions originated the following classification: 1. superficial atypical proliferation significance; 2. melanocytic tumor of uncertain potential; 3. pigmented epithelioid melanocitoma of uncertain potential; 4. microinvasive radial growth phase of uncertain potential. The terminology remains controversial, reflecting the uncertainty of the diagnosis and the biological potential of these atypical melanocytic lesions.
