Propranolol for treatment of infantile hemangiomas.

Infantile hemangioma is the most common vascular tumor in early childhood. Propranolol has been successfully used recently in a limited number of children with Infantile hemangioma. We present 6 cases of Infantile hemangioma, at a single dermatological center, which responded to oral propranolol with good results.

Topical photoprotection in childhood and adolescence.

OBJECTIVE: Exposure to sunlight in childhood is often more intense than in adults. Literature data unequivocally show the association between this social behavior and the risk for developing malignant melanoma and non-melanoma skin cancer, even in adulthood. Furthermore, skin photoaging begins already in childhood through inadequate sun exposure. This review aims to guide pediatricians on appropriate measures of topical photoprotection in children and adolescents, which will positively change the future of these patients. SOURCES: A review of the literature indexed in MEDLINE/PubMed between the years 1999 and 2012 on photoprotection in childhood was conducted. The most relevant review articles on photoprotection in children and adolescents, photoprotection and vitamin D in neonatal phototherapy and impact on skin cancer, artificial tanning and skin cancer were selected as sources. SUMMARY OF THE FINDINGS: Children and adolescents should adopt appropriate measures of photoprotection in order to decrease the risk of melanoma and non-melanoma skin cancer. CONCLUSIONS: There are published data that support the association between sun exposure habits and safe use of topical sunscreens in children and adolescents on the one hand and a reduced occurrence of skin cancer on the other.

Fotoproteção tópica na infância e na adolescência / Topical photoprotection in childhood and adolescence

OBJETIVO: A exposição à luz solar na infância ocorre, frequentemente, de forma mais intensa do que em muitos adultos. Dados da literatura comprovam de maneira inequívoca a associação desse comportamento social com o risco de desenvolvimento do melanoma maligno e do câncer cutâneo não melanoma mesmo na vida adulta. Além disso, o fotoenvelhecimento cutâneo é semeado já na infância com a exposição solar inadequada. Esta revisão tem como objetivo orientar os pediatras nas medidas adequadas de fotoproteção tópica nas crianças e adolescentes, o que irá alterar de maneira positiva o futuro desses pacientes. FONTES DOS DADOS: Realizou-se uma revisão da literatura indexada na base de dados MEDLINE/PubMed entre os anos de 1999 e 2012 sobre fotoproteção na infância, selecionando-se como fonte os artigos de revisão mais relevantes, do ponto de vista de abrangência do tema fotoproteção em crianças e adolescentes, fotoproteção e vitamina D, fototerapia na neonatologia e impacto no câncer cutâneo, bronzeamento artificial e câncer cutâneo. SÍNTESE DOS DADOS: Crianças e adolescentes devem adotar medidas adequadas de fotoproteção para diminuir o risco de câncer cutâneo melanoma e não melanoma. CONCLUSÕES: Há dados na literatura que suportam a associação de hábitos de exposição solar segura e uso de fotoprotetores tópicos em crianças e adolescentes com a redução da ocorrência do câncer cutâneo.

Epidermolysis bullosa nevi: clinical, dermatoscopical and histological features in a case of recessive dystrofic form.

Acquired melanocytic lesions may present unusual clinical features in all forms of hereditary epidermolysis bullosa. These lesions are known as "EB nevi", and often pose a diagnostic challenge for dermatologists given their resemblance - clinically, dermoscopically and histologically - to melanoma. The lesions have been reported in all types of hereditary EB, most of them in childhood. We report the case of a 6-month-old boy suffering from recessive dystrophic epidermolysis bullosa (RDEB) that presented as a large pigmented lesion on his left thigh. We decided to monitor the lesion closely since we considered that the clinical and pathological aspects of the lesion were compatible with the description of other previously reported cases of EB nevi.

Nevo da epidermólise bolhosa: aspectos clínicos, dermatoscópicos e histológicos em um caso de portador da forma distrófica recessiva / Epidermolysis bullosa nevi: clinical, dermatoscopical and histological features in a case of recessive dystrofic form

As lesões melanocíticas adquiridas podem apresentar aspecto clínico não-usual em pacientes portadores de epidermólise bolhosa hereditária. Essas lesões são conhecidas como "nevos EB" e, muitas vezes, constituem um desafio diagnóstico ao dermatologista por apresentarem características clínicas, dermatoscópicas e histopatológicas semelhantes às encontradas no melanoma. Não são exclusivas de nenhuma forma de epidermólise bolhosa e têm sua frequência aumentada na infância. Relata-se o caso de um doente do sexo masculino, de 6 meses de idade, portador da forma distrófica recessiva da doença, com lesão pigmentada de rápido crescimento na coxa esquerda. Optou-se por seguimento clínico da lesão, considerando que os aspectos clínicos, dermatoscópicos e histológicos eram compatíveis com a descrição de outros casos de nevo EB previamente descritos.
