Accuracy in the Clinical Diagnosis and Pattern of Malignant Melanoma at a Dermatological Clinic

The diagnostic pattern of malignant melanoma and clinical suspicion rate has been investigated at a dermatological university clinic. Of 174 histologically proven malignant melanomas, 60 (34%) were not clinically suspected as melanomas. The accuracy of clinical diagnosis increased with level of experience. Physicians with < 1 year experience in dermatology were able to detect malignant melanoma as the first diagnosis in 31% of the cases in contrast to 63% for those with > 10 years experience. Of 50 patients immediately referred from the dermatologic clinic to surgery departments, 12 did not have melanoma.
