BACKGROUND There is a need for better standardization of the dermoscopic terminology in assessing pigmented skin lesions. OBJECTIVE The virtual Consensus Net Meeting on Dermoscopy was organized to investigate reproducibility and validity of the various features and diagnostic algorithms. METHODS Dermoscopic images of 108 lesions were evaluated via the(More)
OBJECTIVE To determine the predictive dermoscopic features of amelanotic and hypomelanotic melanoma. DESIGN A total of 105 melanomas (median Breslow thickness, 0.76 mm), 170 benign melanocytic lesions, and 222 nonmelanocytic lesions lacking significant pigment (amelanotic, partially pigmented, and light colored) were imaged using glass-plate dermoscopy(More)
Nonmelanoma skin cancer refers to a broad class of tumors, including actinic keratosis, basal cell carcinoma, and squamous cell carcinoma, and as a group these are the most frequent cancers occurring in light skinned humans. In contrast to the rarity of amelanotic melanoma, nonmelanoma skin cancer commonly lacks pigmentation. Although these tumors rarely(More)
Dermoscopy is a noninvasive tool that can be helpful in the diagnosis of nonpigmented skin tumors. This is because dermoscopy permits the visualization of key vascular structures that are usually not visible to the naked eye. Much work has concentrated on the identification of specific morphologic types of vessels that allow a classification into(More)
these key points have been previously published; however, some are based on clinicians’ personal intuition and lack any good scientific data at present. In the future, through ongoing research in dermoscopy by clinicians both locally and through the International Dermoscopy Society, the list of key points will undoubtedly evolve as more scientific data(More)
OBJECTIVES To describe morphological features of seborrheic keratosis as seen by dermoscopy and to investigate their prevalence. DESIGN Prospective cohort study using macrophotography and dermoscopy for the documentation of seborrheic keratosis. SETTINGS Seborrheic keratoses were prospectively collected in 2 sites: a private practice in Plantation, Fla(More)
In this paper, a new approach to computer supported diagnosis of skin tumors in dermatology is presented. High resolution skin surface profiles are analyzed to recognize malignant melanomas and nevocytic nevi (moles), automatically. In the first step, several types of features are extracted by 2D image analysis methods characterizing the structure of skin(More)
