Blue Lesions
Blue color is found in a wide range of malignant and benign melanocytic and nonmelanocytic lesions and in lesions that result from penetration of exogenous materials, such as radiation or…
Special Criteria for Special Locations 2
The anatomic region influences the dermoscopic features of different lesions. In this article, the particular characteristics of the scalp, mucosal membranes, and lesions located on the milk line are explained….
Special Locations Dermoscopy
Although dermoscopy reflects the anatomy, skin anatomy is different on facial and acral skin as well as in the nail unit. Malignant patterns on acral sites include the parallel ridge…
The Morphologic Universe of Melanoma
Differentiating dysplastic nevi from melanoma remains one of the main objectives of dermoscopy. Melanomas tend not to manifest any of the benign patterns described for nevi and instead usually display…
Spitz Nevus, Spitz Tumor, and Spitzoid Melanoma
Spitz nevus can clinically present either in the classical (reddish pink) or the pigmented (brownish black) variant. Dermoscopy demonstrates that the pigmented variant is much more common than the classical…
Dysplastic Nevus
The term “dysplastic nevus” is a misnomer and should be abandoned. Dysplastic nevus is not just a name, it is the root of the concept that histomorphology (or any morphologic…
Monitoring Patients with Multiple Nevi
Early recognition is the most effective intervention to improve melanoma mortality. Early diagnosis of melanoma in atypical mole syndrome patients, however, may be challenging. Skin self-examination and periodic physician-based total-body…
Problematic Lesions in the Elderly
As the population continues to age, clinicians and dermatologists are increasingly faced with geriatric patients presenting with a range of dermatologic manifestations, including benign and malignant skin tumors. Knowledge of…
Problematic Lesions in Children
Melanoma in childhood is rare, and appears more commonly either in association with a preexisting (congenital) nevus, or with spitzoid features than de novo. Thus, problematic melanocytic lesions in children…
A Clinico-Dermoscopic Approach for Skin Cancer Screening
Dermoscopy is useful for skin cancer screening, but a detailed approach is required that integrates this tool into a rational clinical work flow. To investigate clinician perceptions and behavior in…
