BACKGROUND It is often difficult to differentiate early melanoma from benign pigmented lesions of similar clinical appearance. OBJECTIVE Our purpose was to develop a computer image analysis system that has the potential for use as an adjunct to the clinical distinction of melanoma from less serious pigmented lesions. METHODS The system, consisting of a hand-held device incorporating a color...

BACKGROUND Teledermatology may be less optimal for skin neoplasms than for rashes. OBJECTIVES We sought to determine agreement for skin neoplasms. METHODS This was a repeated measures study. Each lesion was examined by a clinic dermatologist and a teledermatologist; both generated a primary diagnosis, up to 2 differential diagnoses, and management. Macro images and polarized light dermoscop...

Small pigmented lesions in children can represent a significant diagnostic challenge. If the diagnostic features and therapeutic approach are relatively well established in large and giant nevi, there is still much controversy regarding small and intermediate-sized congenital pigmented lesions that can lead to significant diagnostic challenges, both clinically and dermoscopically, and consequen...

Dermoscopy is an in vivo method for the early diagnosis of malignant melanoma and the differential diagnosis of pigmented lesions of the skin. It has been shown to increase diagnostic accuracy over clinical visual inspection in the hands of experienced physicians. This article is a review of the principles of dermoscopy as well as recent technological developments.

background although, melasma is most prevalent among asian young women, and also darkly pigmented individuals are particularly prone to developing post inflammatory hyperpigmentation, to the best of our knowledge, there are rare or no studies about the association of melasma and post inflammatory hyperpigmentation. results we found out that 24.1% of patients without melasma had post-acne pigmen...

Whether the diagnosis of any particular nevus is problematic or not depends upon a variety of factors, including the experience and enthusiasm of the pathologist, the nature of the specimen (shave vs. punch vs. excisional), the quality of the sections (and their staining), the hour of the day or day of the week in addition to the problems relating to the ever-increasing range of histological va...

This paper describes the basic concepts of dermoscopy, the various dermoscopic equipments and the standard criteria for diagnosing pigmented skin lesions. In assessing dermoscopic images, both global and local features can be recognized. These features will be systematically described and illustrated in Part I of this article. First, we will focus on 8 morphologically rather distinctive global ...

OBJECTIVES To determine whether an aid to the diagnosis of pigmented skin lesions reduces the ratio of benign lesions to melanomas excised in general practice. DESIGN Controlled trial randomised by practice. SETTING General practices in Perth, Western Australia. PARTICIPANTS 468 general practitioners in 223 practices. INTERVENTIONS Intervention practices were given an algorithm and inst...
