BACKGROUND Digital dermoscopy is the gold standard follow-up method for patients with high risk for developing cutaneous malignant melanoma. By comparing the same lesion at different moments, it allows early detection of subtle changes that could suggest the diagnosis of melanoma. Thus, it is clear that the test must be repeated after a period of time, according to time intervals determined by ...

Dermoscopy is one of the major imaging aspects used in the skin lesions. This paper presentsa new tacticfor the segmentation of skin abrasionsin dermoscopic images based on fuzzy Cmeans algorithm learned wavelet network (WN). The WN offeredhere is a member of fixed-grid WNs that is designedwith no requirementof training. Fuzzy C-means techniqueis used to enhancethe network structure. In additio...

When Harald Kittler asked me to write an editorial on der-moscopy (to be precise, he used the linguistically correct term dermatoscopy) for Dermatology Practical & Conceptual, the journal founded by Bernie Ackerman and now under his edi-torship, I must admit I accepted his invitation with an element of uneasiness. Perhaps because I recall that Bernie never really embraced dermoscopy and not sim...

-Melanoma is the most dangerous type of skin cancer. Uncontrolled growth of cancer cells are mostly occurs in melanocytes. In spite of, to prevent its deadly consequences and for treatment to be efficient, to perform the early diagnostic of the melanoma efficient treatment is necessary. The diagnostic of melanoma, without any support is not possible, therefore dermoscopy was created. Dermoscopy...

INTRODUCTION Melanoma presents the greater threat to health the later the disease is detected and treated, although treatment results can be improved by the widespread use of dermoscopy. However, scarce data are available concerning the awareness of dermoscopy and the frequency of its performance in the non-patient population. AIM To assess the awareness of melanoma detection by dermoscopic e...

Dermoscopy plays an important role in the diagnosis of pigmented lesions, particularly in the differential diagnosis of early-stage melanoma. Dermoscopy systems that aim to enable automatic "unmanned-without physician" diagnosis are becoming increasingly common. We aimed to investigate the reliability and weaknesses of diagnosis programs. Furthermore, we attempted to determine whether such prog...

BACKGROUND The incidence of cutaneous melanoma is increasing worldwide. Since it is an aggressive neoplasm, it is difficult to treat in advanced stages; early diagnosis is important to heal the patient. Melanocytic nevi are benign pigmented skin lesions while atypical nevi are associated with the risk of developing melanoma because they have a different histological pattern than common nevi. Th...

OBJECTIVE To analyze dermoscopically identified streaks by direct correlation with features visualized on reflectance confocal microscopy (RCM). DESIGN We evaluated by RCM melanocytic lesions showing peripheral streaks on dermoscopy. A digital camera connected to the RCM computer enabled direct analysis of the streaks. The lesions were excised and histopathologically analyzed. SETTING Derma...

Introduction: Melasma is the main cause of facial hyperchromia and has a signifi cant psychosocial impact. Wood ́s lamp has been a useful device to estimate the depth of melanin determined by light-induced fl uorescence. A dermoscope enables a clear visualization of pigments distribution, and the color variation of melanin will depend on its location within the skin. Objective: Evaluate the clas...
