Histologic review of melanomas by pathologists trained in melanocytic lesions may change therapeutic approach in up to 41 9% of cases

ABSTRACT

Abstract Melanoma Guidelines of the Brazilian Dermatology Society recommend histologic review by pathologists trained in melanocytic lesions whenever possible. Out of 145 melanoma cases identified at a private clinic in São Paulo/Brazil, 31 that had been submited to histologic review were studied to evaluate whether revision had led to change in therapeutic approach.. Differences in original/reviewed reports were found in 58.1% (n=18) of the reports, leading to changes in therapeutic approach in 41.9% (n=13). Change in diagnosis was observed in 6 out of 31 (19,3%) cases. These findings suggest that second opinion by pathologists trained in melanocytic lesions is likely to show significant differences from the original report.
