Résumé
Dermoscopy is a method of increasing importance in the diagnoses of cutaneous diseases. On the scalp, dermoscopic aspects have been described in psoriasis, lichen planus, seborrheic dermatitis and discoid lupus. We describe the "comma" and "corkscrew hair" dermoscopic aspects found in a child of skin type 4, with tinea capitis.
A dermatoscopia é um método que ganha cada vez mais importância na diagnose de diversas dermatoses. No couro cabeludo, já foram descritos os aspectos dermatoscópicos presentes na psoríase, no líquen plano, na dermatite seborréica e no lúpus discóide. Nós descrevemos padrão dermatoscópico de "cabelos em vírgula e em saca rolhas" encontrado em uma criança com fototipo 4, com tinha do couro cabeludo.

O nevo de Spitz é uma lesão melanocítica benigna com características clínicas e histopatológicas semelhantes às do melanoma. Foi descrito em 1948, mas até hoje, ainda, existe grande controvérsia no seu diagnóstico e conduta. A utilização da dermatoscopia pode aumentar a sua acurácia diagnóstica. As características dermatoscópicas do nevo de Spitz incluem um padrão estelar (starburst), que é o mais frequente, seguido do padrão globular e do padrão atípico. O diagnóstico deve ser confirmado por exame histopatológico, principalmente, nos casos atípicos.
The Spitz nevus is a benign melanocytic lesion with clinical and histopathological features similar to those of melanoma. It was first described in 1948 but great controversy still remains today with respect to its diagnosis and management. The use of dermoscopy may increase diagnostic accuracy. In Spitz nevus, the most common dermoscopic finding is a starburst-like pattern, followed by globular and atypical patterns. Diagnosis must be confirmed by histopathology, particularly in atypical cases.

Leprosy is an important public health problem in Brazil. However, this disease is still poorly diagnosed in its early stages, leading to permanent disability and disfigurement. We examined eight patients with clinical and histologicaldiagnosis of multibacillary leprosy who were being treated for other diseases for about three years without clinicalhypothesis of leprosy. These cases illustrate the importance of medical education and public information aboutleprosys signs and symptoms for prompt recognition and treatment, which are necessary to prevent permanentdisabilities and eradicate the disease.
