The adoption of dermoscopy in routine melanoma screening is followed by an improvement of the malignant/benign ratio in excised lesions, suggesting a more appropriate selection of pigmented lesions referred to surgery. Because of the possible limitations of a retrospective study design, future confirmation of this finding by means of a prospective, randomized study is advisable. The introduction of dermoscopy in routine practice may have major implications in large-scale melanoma screening with cost savings and a reduction of the dermosurgery workload.

To investigate patterns of detection and variables associated with early diagnosis of melanoma in a population at intermediate melanoma risk.Design: Survey.Setting: Hospital and university centers belonging to the Italian Multidisciplinary Group on Melanoma.Patients: Eight hundred sixteen patients who were consecutively diagnosed as having melanoma and treated at 11 participating centers.Main Outcome Measure: Relationship between patterns of detection and patient's and physician's delay with melanoma thickness, assessed by multivariate analysis.Results: A statistically significant association with early diagnosis was found for female sex (odds ratio [OR] for a lesion Ͼ1 mm in thickness, 0.70; 95% confidence interval [CI], 0.50-0.97), higher educational level (OR, 0.44; 95% CI, 0.24-0.79), residence in northern and central Italy (compared with southern Italy) (OR, 0.44; 95% CI, 0.30-0.65 and OR, 0.24; 95% CI, 0.15-0.37, respectively), and the habit of performing a skin self-examination (OR, 0.65; 95% CI, 0.45-0.93). When adjusted for all the previously mentioned variables, only melanoma detection made by a dermatologist, maybe incidentally, was associated with a statistically significant additional effect on early diagnosis (OR, 0.45; 95% CI, 0.28-0.73). No significant effect of anatomical site (trunk compared with other sites: OR, 0.83; 95% CI, 0.59-1.17), presence of atypical nevi (OR, 0.78; 95% CI, 0.52-1.17), and patient's delay (Ͼ3 months compared with Յ3 months: OR, 1.12; 95% CI, 0.78-1.60) was found. Conclusion:Future melanoma early diagnosis strategies should adequately stress the role of skin self-examination among the adult population, and should recommend that dermatologists perform a total skin examination to identify suspect lesions (such an examination should also be performed during consultations for other reasons).

Self-detection of suspicious pigmented skin lesion combined with rapid referral to dermatologic centres is the key strategy in the fight against melanoma. The investigation of factors associated with pattern of detection of melanoma (self- vs. nonself-detection) may be useful to refine educational strategies for the future. We investigated the frequency of melanoma self-detection in a Mediterranean population at intermediate melanoma risk. A multicentric survey identified 816 consecutive cases of cutaneous melanoma in the period January to December 2001 in 11 Italian clinical centres belonging to the Italian Multidisciplinary Group on Melanoma. All patients filled a standardized questionnaire and were clinically examined by expert dermatologists. Self-detected melanomas were 40.6%, while the remaining lesions were detected by a dermatologist (18.5%), the family physician (15.2%), other specialists (5%), the spouse (12.5%), a friend or someone else (8.2%). Variables associated with self-detected melanomas were female sex, young age, absence of atypical nevi, knowledge of the ABCD rule, habit of performing skin self-examination. Self-detected melanomas did not differ from nonself-detected tumours in term of lesion thickness; however, patients with self-detected melanomas waited a longer period before having a diagnostic confirmation (patient's delay) (> 3 months: odds ratio, 3.89; 95% confidence interval, 2.74-5.53). In order to reduce the patients' delays, educational messages should adequately stress the need for a prompt referral to a physician once a suspicious pigmented lesion is self-detected.
