INTRODUÇÃO: Onicomicose é a infecção fúngica das unhas e é considerada a onicopatia mais frequente em adultos. Representa até 50% das lesões ungueais, sendo necessária confirmação diagnóstica com exame complementar que demostre a presença do fungo na unha, sendo o exame micológico direto e a cultura para fungos os mais utilizados. A dermatoscopia é um exame não invasivo, rápido e de baixo custo cujos padrões para onicomicose relatados na literatura em estudos retrospectivos chegam a 100% de sensibilidade e especificidade. Deste modo realizamos um estudo prospectivo para comparar a dermatoscopia frente ao exame micológico. MÉTODOS: Estudo prospectivo, transversal avaliando 109 pacientes e 202 unhas com suspeita diagnóstica de onicomicose. Os padrões dermatoscópicos encontrados foram descritos através de fotografias digitais. A sensibilidade e especificidade dos padrões de onicomicose distal-lateral foram determinados de acordo com o resultado do exame micológico. RESULTADOS: Foram significativos (p < 0,05) para o diagnóstico de onicomicose distal lateral e tiveram sensibilidade/especificidade calculadas os padrões: borda recortada (80,2% / 65,3%), borda linear (12,6% / 42,9%), estrias irregulares (81,1% / 65...

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 by dermoscopy, was performed to clarify the findings.

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 common definitions of nail plate dermoscopy was addressed during the Second Meeting of this Group held in February 2008. Prior to this meeting and to date (2010) there have been no evidence-based guidelines on the use of dermoscopy in the management of nail pigmentation.

Argyria is a rare disease caused by prolonged skin contact with silver. Localized cases have been described regarding the use of topical medications, and trauma with objects containing this metal such as acupuncture needles and jewelry. Clinically, a macule or a patch, round or oval, appears in the infected area, with a characteristic bluey-gray color. To our knowledge this is the first time that this clinical condition has been described through the use of dermoscopy.

The acral melanoma is the most prevalent type of melanoma in the non-Caucasian population, and dermoscopy is a useful tool for earlier diagnosis and differentiation from benign lesions. The dermoscopic pattern often associated with melanoma on the volar skin is the parallel ridge, with 99% specificity according to the literature. However, this pattern can also occur in several benign acral lesions, so it is important to make a good interpretation of this pattern, along with the clinical history and evolution.

Poromas are uncommon benign neoplasms originating from the terminal ductal portion of the sweat glands, mainly characterized by skin-colored or pink pa pules or nodules, usually on the extremities. Due to their rarity, the pigmented form clinical hypothesis is hardly ever suggested and psychopathology is fundamental. We report a case of pigmented eccrine poroma in the right palmer area, a location considered atypical. We stress the importance of dermoscopy as a method for diagnosis of poromas, especially in the differential diagnosis with other pigmented nodular-popular lesions.

An uncommon skin manifestation of Dermatitis Herpetiformis is palmar and plantar purpura. Dermoscopic examination is useful for any skin condition since it allows recognition of structures that are not discernible to the naked eye. A 22 year-old Caucasian man was admitted with excoriated lesions and pruritus. Petechial lesions could be seen on volar aspect of the digits on the hands and feet. Dermoscopy examination revealed erythematous and violaceous dots and erythematous and brown dots.

The granuloma faciale is a rare and benign skin disease of unknown etiology, characterized by chronic leukocitoclastic vasculitis. It is characterized by skin lesions predominantly facial whose course is chronic and slowly progressive. The diagnosis is based on clinical features, histopathology and, more recently, in dermoscopy. We describe the case of a male patient, 40 years old, with a sarcoid lesion on the malar site, whose histopathological examination revealed a mixed inflammatory infiltrate with presence of Grenz zone. Dermoscopy revealed a pink background with white striations. The definitive diagnosis is made by histopathologic evaluation, and dermatoscopy can be helpful. It is known to be resistant to therapy, oral medications, intralesional and surgical procedures are options.

BACKGROUND: Skin cancer is the most common malignancy and can be treated in various ways. One treatment modality is Mohs micrographic surgery. Due to the increasing incidence of skin cancer in the last decades, there is a need for improvement of the Mohs technique to optimize its effectiveness. OBJECTIVE: The aim of this study was to evaluate the use of dermoscopy to guide demarcation of Mohs micrographic surgery margins and ascertain whether this method can reduce operative time and, therefore, reduce surgical morbidity and cost. METHODS AND MATERIALS: The sample comprised 44 patients who underwent Mohs micrographic surgery, allocated into two groups: the control group and the intervention group. In the latter, surgical margins were guided by dermoscopy. RESULTS: There were no statistically significant differences between the two groups by chi-square analysis (p = 0.399). CONCLUSION: Although outcomes were similar in the two groups, demonstrating that dermoscopy does not help in the demarcation of surgical margins for Mohs micrographic surgery, the study provides a practical proposal for improvement of the Mohs technique.

We describe the case of a 32-year-old male patient that sought medical treatment complaining of severe pain in his second and third right-hand fingers. The symptoms had started two hours before. The hypotheses of spider bite, scorpion or insect sting and injury caused by a foreign body were considered in the differential diagnoses. On dermoscopy, two foreign bodies were identified on his skin. After extraction, we concluded that they were wasp stingers.

BACKGROUND: Digital dermoscopy is the gold standard follow-up method for patients with high risk for developing cutaneous malignant melanoma. By comparing the same lesion at different moments, it allows early detection of subtle changes that could suggest the diagnosis of melanoma. Thus, it is clear that the test must be repeated after a period of time, according to time intervals determined by the evaluator. OBJECTIVES: To evaluate adherence of patients to follow-up examinations using digital dermoscopy. METHOD: Retrospective analysis of 36 patients who underwent digital dermoscopic examination and total-body photography in a private medical center between September 2010 and January 2013. Results: Only 25% of the patients returned for followup evaluations. CONCLUSIONS: Low adherence to digital dermoscopy follow-up could compromise the efficacy of this valuable method. This lack of adherence represents a challenge for the evaluator.

Furuncular myiasis occurs after larvae penetrate on the skin. The disease is characterized by the presence of a nodule with a central hole through which there is serosanguinous exudate drainage. The authors present a case of furuncular myiasis by Dermatobia hominis in which late diagnosis made it necessary to have the orifice margins surgically enlarged in order to extract the larva. They also emphasize that dermoscopy is a useful auxiliary tool in this diagnosis.

Temporal triangular alopecia, also referred as congenital triangular alopecia, is an uncommon dermatosis of unknown etiology. It is characterized by a non-scarring, circumscribed alopecia often located unilaterally in the frontotemporal region. It usually emerges at ages 2-9 years. Alopecia areata is the main differential diagnosis, especially in atypical cases. Dermoscopy is a noninvasive procedure that helps distinguish temporal triangular alopecia from aloepecia areata. Such procedure prevents invasive diagnostic methods as well as ineffective treatments.

Abstract BACKGROUND: Basal cell carcinoma is the most frequent cancer in fair-skinned populations and dermoscopy is an important, non-invasive technique that aids in the diagnosis of Basal cell carcinoma. OBJECTIVES: The aim of this study was to evaluate the relationship between histopathological subtypes and dermoscopic features of Basal cell carcinoma. METHODS: This study included 98 patients with clinically and histopathologically confirmed Basal cell carcinomas. The dermoscopic features of the lesions from each patient were analyzed before the histopathological findings were evaluated. RESULTS: Dermoscopic structures were observed in all 98 patients and irregular vascularity was identified in 78 patients (79.6%). The most common vascular pattern was the presence of arborizing vessels (42 patients, 42.9%) followed by arborizing microvessels (21 patients, 21.4%) and short fine telangiectasias (SFTs; 15 patients, 15.3%). White streaks (38 patients, 38.8%), translucency (31 patients, 31.6%), a milky-pink to red background (42 patients, 42.9%), and erosion/ulceration (29 patients, 29.6%) were also observed. Pigmented islands were seen as blue-gray globules (7 patients, 7.1%) and blue-gray ovoid nests (42 patients, 42.9%). The pigment distribution pattern was maple leaf-like areas in 9 patients (9.2 %) and spoke wheel-like areas in 6 patients (6.1%). CONCLUSIONS: Basal cell carcinomas show a wide spectrum of dermoscopic features. Arborizing vessels were the most common dermoscopic findings in Basal cell carcinomas...
