Patients with sleep apnea will be treated.\n\nStandard dermatologic follow-up over a 3 years period with thoraco-abdominal-pelvic and cerebral CT-scan and a lymph-node ultrasound every 6 months will be performed.\n\nSample size: based on previous data from the investigators showing that 25% of patients with a Breslow's Thickness ≥ 1mm will have node or visceral metastasis. For an alpha threshold of 5% and a study power of 80%, with 5% of dropouts, with the hypothesis that 40% of apnea syndrome patients will metastasis versus 20% in the control group the study should include 83 patients in each group.\n\nStatistical analysis: an intermediate analysis after 80 included patients will be performed. Peto method will be followed, results will be considered significant with a p≤0.001 and the study will be stopped.\n\nNormality of data will be checked by Kurtosis and Skewness tests, variance equality will be tested with the Leven test.
