BACKGROUND: Few studies have evaluated the role of digital dermoscopy (DD) in the surveillance of pigmented lesions in real-life practice.
PATIENTS AND METHODS: Patients followed with DD by 4 hospital dermatologists (group 1) and 4 private dermatologists (group 2) were retrospectively included if they had had at least 2 DD examinations for a minimum of 4 pigmented lesions. Their characteristics, risk factors, history of excision of benign nevi and melanomas prior to and during the DD follow-up, and characteristics of detected melanomas, were recorded.
RESULTS: One hundred and ninety-six patients were included in group 1 and 205 in groups 2. A family history of melanoma (25% vs. 12%, p<0.01), a personal history of melanoma before DD follow-up (47% vs. 15%, p<0.01), and a family (3% vs. 0%, p=0.01) and personal (8% vs. 1%, p<0.01) germline CDKN2a mutation were more frequent in group 1 than in group 2. In both groups, the number of excisions of benign lesions was higher before DD follow-up (380 and 347, respectively) than during DD follow-up (194 and 132). During follow-up, 29 melanomas were detected in group 1, with a median Breslow thickness of 0.4mm, versus 1.3mm for melanomas diagnosed before DD follow-up (p<0.02). In group 2, 4 melanoma and 5 superficial atypical melanocytic proliferations of unknown significance were detected. The median Breslow thickness of newly diagnosed melanomas was 0.35mm vs. 0.6mm before DD follow-up (p=0.1).
CONCLUSION: In both populations in real-life practice, DD seemed to allow the detection of thin melanomas and to decrease the rate of "futile" resections.
