BACKGROUNDS Although easily diagnosed, molluscum contagiosum may present as a single lesion or as several small, inflamed lesions of difficult diagnosis. OBJECTIVE To describe the dermoscopic characteristics of molluscum contagiosum and to compare the findings from clinical examination and dermoscopy. METHODS Histopathologically confirmed lesions were evaluated clinically and dermoscopicall...

We recently described an in vivo reflectance confocal microscopy (RCM) method and our aim was to evaluate a possible additive value of this type of analysis in the management of melanocytic lesions. In two referral centers (Sydney and Modena), lesions (203 nevi and 123 melanomas (MMs) with a median Breslow thickness of 0.54 mm) were excised on the basis of clinical suspicion (history, dermoscop...

The aim of the present study was to assess the function of dermoscopy in evaluating the therapeutic efficacy of tacrolimus ointment plus 308-nm excimer laser combination therapy in patients with localized vitiligo. A total of 147 patients with localized vitiligo (progressive disease, n=92; stable period, n=55) were enrolled and received combination therapy for 12 weeks. The condition of the ski...

Dermoscopy or videodermoscopy has been proven to be a valuable tool in the evaluation of various changes in the hair and scalp in recent years. Although an immersion gel or liquid is conventionally utilized fort the diagnosis of pigmented tumors, examination of hair and scalp may efficiently be performed with dry dermoscopy. A significant number of studies indicating availability of dermoscopy ...

OBJECTIVES To examine the role of sequential dermoscopy imaging in detecting incipient melanoma and to elucidate the impact of length of follow-up on the relevance of observed changes. DESIGN Baseline and follow-up images of melanomas and melanocytic nevi excised only because of changes across time were inspected on a computer screen and assessed according to prospectively defined criteria. L...

Melanoma, the deadliest form of skin cancer, must be diagnosed early for effective treatment. Irregular pigment network and streaks are important clues for melanoma diagnosis using dermoscopy images. This thesis describes novel image processing approaches for computer-aided pigment network and streaks detection on dermoscopy images. Our methods provide meaningful visualization of these structur...

It may be clinically difficult to differentiate early-stage melanoma from benign tumors, specially pigmented seborrheic keratosis. Dermoscopy can help; however, the findings are not always conclusive. Therefore, histopathology may be necessary for a correct diagnosis. We describe a melanocytic lesion with dubious clinic and dermoscopic findings. An incisional biopsy of a suspicious area, guided...

BACKGROUND The number needed to treat (NNT) ratio is an effective method for measuring accuracy in melanoma detection. Dermoscopy reduces the number of false positives and subsequently unnecessary excisions. In vivo reflectance confocal microscopy (RCM) is a noninvasive technique that allows examination of the skin with cellular resolution. OBJECTIVES To assess the impact of RCM analysis on t...

OBJECTIVES To determine students' ability to discriminate benign vs malignant lesions and to assess attitudes regarding skin cancer examination (SCE). DESIGN Second-year medical students at 1 institution participated in an SCE intervention for 2 consecutive years. INTERVENTION Cohort 1 received intervention A, consisting of SCE teaching without a dermoscopy tutorial. Cohort 2 received inter...

This statement, focused on melanonychia and nail plate dermoscopy, is intended to guide medical professionals working with melanonychia and to assist choosing appropriate management for melanonychia patients. The International Study Group on Melanonychia was founded in 2007 and currently has 30 members, including nail experts and dermatopathologists with special expertise in nails. The need for...
