Dermoscopy basics and melanocytic lesions ( Part 1 of 2 )

چکیده
Tokyo Women's Medical University Medical Center East, 2-1-10 Nishi-Ogu, Arakawa-ku, Tokyo 116-8567, Japan A dermoscope is a "stethoscope" for a dermatologist. It is more important to "use" dermoscope than to "learn" it. In the first part of this review, colour and structures of the pigmented lesions on dermoscopy will be elaborated. The important features on dermoscopy to differentiate melanoma from naevus will be discussed. The basic diagnostic approach for pigmented skin lesions will be introduced. It is essential for the readers to continue reading the second part of this review in the next issue in order to get the complete picture about the dermoscopy basics and melanocytic lesions.

Correlation of dermoscopy with in vivo reflectance confocal microscopy of streaks in melanocytic lesions.
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...
متن کاملDermoscopic patterns of benign volar melanocytic lesions in patients with atypical mole syndrome.
BACKGROUND Acral benign melanocytic lesions in white populations, particularly in subjects with atypical mole syndrome, have been poorly characterized until recently. The advent of dermoscopy has enabled more specific diagnoses of these pigmented skin lesions. OBJECTIVE To evaluate the clinical and dermoscopic features of benign volar lesions in a group of white patients with atypical mole sy...
متن کاملHistopathological diagnosis of small melanocytic lesions suspicious for malignant melanoma*
The concern about malignant skin neoplasms leads to the excision of smaller lesions. This study on small melanocytic lesions aims to evaluate the range of possible histopathological diagnoses, describe histopathological aspects, and assess the usefulness of serial histological sections. We performed a cross-sectional descriptive histopathological study examining 76 pigmented skin lesions up to ...
متن کاملMelanoma detection with a deep learning model
Background: Skin cancer is one of the most common forms of cancer in the world and melanoma is the deadliest type of skin cancer. Both melanoma and melanocytic nevi begin in melanocytes (cells that produce melanin). However, melanocytic nevi are benign whereas melanoma is malignant. This work proposes a deep learning model for classification of these two lesions. Methods: In this analytic s...
متن کاملLimitations of dermoscopy in the recognition of melanoma.
OBJECTIVE To compare dermoscopic features of melanocytic nevi with those of early melanomas that were not excised initially because of their uncharacteristic clinical and dermoscopic appearance. DESIGN Retrospective study of the baseline images of 325 melanocytic skin lesions that were observed by digital dermoscopy and finally excised because of changes over time. SETTING A dermatologic cl...
