PG - 23-7 AB - Twenty-two surgical biopsy specimens from patients with pigmented skin neoplasms were studied. The patients were divided into 3 groups: 1) 11 patients who had a histological verified diagnosis of melanoma; 2) 10 patients who were diagnosed as having nevi with lentiginous melanocytic dysplasia; 3) 1 patient who had an unclear diagnosis of presumptively, nevus with melanocytic dysplasia. By applying fluorescence in situ hybridization (FISH) by means of a Vysis LSI RREBI/LSI MYB/LSI CCNDI/ CEP 6 probe, the authors employed to test a new probe designed for the genetic diagnosis of melanoma by FISH studies and confirmed in all the 22 patients the diagnosis previously made from the results of the routine histological study and the presumptive diagnosis in 1 patient. Furthermore, it should be noted that multiple genetic disorders were revealed in 3 patients (14% of the total sample and 30% of the sample of patients diagnosed as having nevus with lentiginous melanocytic dysplasia) in the absence of the morphological criteria of melanoma. The patients with such disorders belong to a risk group and need a more meticulous further follow-up.
