Dermoscopy is a non-invasive tool that is largely recognized and used in the diagnosis of pigmented and non-pigmented skin tumors. A steadily increasing number of publications on alternative applications of dermoscopy suggest, however, that dermoscopy aids also the recognition of skin manifestations in general dermatology. The increasing use of dermoscopy in general dermatology can be partially...

There is an increasing demand for automated detection and analysis of dermoscopy structures and malignancy clues such as streaks in dermoscopy images, for computer-aided early diagnosis of deadly melanoma. This paper presents a novel approach for streak detection and visualization on dermoscopic images. We tackle the detection of streaks by means of ridge and valley estimation. Orientation esti...

BACKGROUND Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Owing to the difficulty and subjectivity of human interpretation, dermoscopy image analysis has become an important research area. One of the most important steps in dermoscopy image analysis is the automated detection of lesion borders. Although numerous methods have...

Dermoscopy is already considered a fairly established method for diagnosing scabies. This is because dermoscopy enables the visualization both of the burrow and the mite itself, forming the so-called "jet with a contrail" structure. In the present report we present an extraordinary case of a patient with scabies lesions on the face and neck, which was misdiagnosed during sequential visits and u...

Dermoscopy is a non-invasive skin imaging technique, which permits visualization of features of pigmented melanocytic neoplasms that are not discernable by examination with the naked eye. One of the most important features for the diagnosis of melanoma in dermoscopy images is the blue-white veil (irregular, structureless areas of confluent blue pigmentation with an overlying white "ground-glass...

BACKGROUND Dermoscopy is one of the major imaging modalities used in the diagnosis of melanoma and other pigmented skin lesions. Due to the difficulty and subjectivity of human interpretation, automated analysis of dermoscopy images has become an important research area. Border detection is often the first step in this analysis. In many cases, the lesion can be roughly separated from the backgr...

Dermoscopy is a handy tool originally used for evaluating pigmented lesions and melanoma. However, over the years, numerous indications have cropped up including its role in diagnosing infestations (entomodermoscopy).2 Dermoscopy combines light source and magnifying lens in such a way that it enables visualization of patterns not visible with clinical inspection alone.2 The evidence available r...

PURPOSE Family physicians (FPs) frequently evaluate skin lesions but may not have the necessary training to accurately and confidently identify lesions that require skin biopsy or specialist referral. We evaluated the diagnostic performance of a new, simplified dermoscopy algorithm for skin cancer detection. METHODS In this cross-sectional, observation study, attendees of a dermoscopy course ...

We herein report a case of hair follicle nevus, a rare hamartoma found on the face and showing follicular differentiation, which was associated with sebaceous hyperplasia. Dermoscopy of the lesion showed yellow globules surrounded by crown vessels/telangiectasias and scattered tiny hairs. Histopathological investigation revealed hyperplasia of the sebaceous glands and proliferation of well-diff...

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...
