Blue-black rule: A simple dermoscopic clue to recognize pigmented nodular melanoma

Background  Dermoscopy improves melanoma recognition, but most criteria were described in the context of superficial spreading melanoma.

Dermoscopy of discoid lupus erythematosus

Summary Background  Dermoscopy is useful in evaluating skin tumours, but its applicability also extends into the field of inflammatory skin disorders. Discoid lupus erythematosus (DLE) represents the most common subtype of cutaneous lupus erythematosus. While dermoscopy and videodermoscopy have been shown to aid the differentiation of scalp DLE from other causes of scarring alopecia, limited data exist concerning dermoscopic criteria of DLE in other locations, such as the face, trunk and extremities.

Dermoscopy of Cutaneous Sarcoidosis

Background: The clinical variability of cutaneous sarcoidosis (CS) often makes its correct diagnosis challenging. Although traditionally employed for the diagnosis of skin tumors, during the past years dermoscopy also gained increasing interest as an aid in the clinical diagnosis of inflammatory and infectious skin manifestations in general dermatology. Objective: Our purpose was to evaluate the usefulness of dermoscopy in the differential diagnosis of CS. Methods: This was a retrospective analysis of 7 clinical and dermoscopic images of CS that were collected at dermatology clinics in France and Italy between 2005 and 2009. Results: Retrospective dermoscopic evaluation revealed small grouped, translucent orange globular structures associated with linear vessels of variable diameter in all 7 cases. In 5 cases, additional central scar-like areas were seen. Conclusion: Lesions showing dermoscopically translucent yellow to orange globular-like or structureless areas associated with linear vessels should raise the suspicion of a granulomatous skin disease, including CS.

Clinical, dermoscopic and histopathologic features of genital and extragenital lichen sclerosus

Background  Little is currently known about the dermoscopic patterns of genital and extragenital lichen sclerosus (LS). In order to evaluate and compare the dermoscopic and histopathologic patterns of genital and extragenital lichen sclerosus, a retrospective analysis of clinical, dermoscopic and histopathologic features of genital and extragenital LS, collected between March 2010 and December 2011 at four dermatology clinics in Greece, Italy, Serbia and Uruguay was performed.

Dermoscopic patterns of granuloma annulare and necrobiosis lipoidica

CDNH. The patient improved with a short course of potent topical steroids and replacement of the headwear with a softer material. We could not find any other reports of CDNH caused by turbans in the literature. This is surprising, considering the numbers of turban wearers, but we suspect that many of those affected do not seek medical advice, as they recognize the causative factor themselves. Similar cases of perichondritis caused by the coif of nuns have also been reported. In conclusion, we report a patient with CDNH caused by pressure of his headwear on the ear cartilage. This is only the second such case reported, to our knowledge.

Twenty nevi on the arms: a simple rule to identify patients younger than 50 years of age at higher risk for melanoma.

Patients with a high total nevus count (TNC) merit a total-body examination, but a simple strategy to identify these high-risk individuals is essentially missing. The aim of this study was to investigate the correlation between the number of melanocytic nevi on both arms and the TNC, and to evaluate patient variables that may have an effect on this association. In this multicenter, cross-sectional study, 2175 patients were examined and the mean number of arm nevi in relation to TNC was calculated. A mean value of fewer than 10 arm nevi was found in patients with TNC lower than 51 and a mean value of greater than 19 arm nevi was scored in patients with TNC greater than 50. These values remained unchanged after adjustment for various patient variables. In relation to TNC greater than 50, the presence of 20 or more arm nevi had specificity and negative predictive values of 95.2 and 89.6%, respectively. The sensitivity was 65.5% in patients younger than 50 years of age and 37.5% in the older age group. The number of arm nevi was significantly higher in individuals with a history of melanoma and in those with a melanoma detected during the study period. The presence of 20 or more nevi on the arms is an independent predictor of a high TNC and risk of melanoma. This sign thus represents a simple and rapid screening tool for either the primary care physician or the dermatologist to help identify high-risk patients.
