Sunscreens are indicated for the prevention of actinic damage to the skin, however, there are few clinical trials assessing the synthesis of cutaneous VD in real-life situations of sun exposure with ordinary clothing and usual photoprotection. Objectives: To evaluate...

Os histiócitos e as histiocitoses não Langerhans em dermatologia
Luz,Flávio Barbosa; Gaspar,Antônio Pedro; Kalil-Gaspar,Neide; Ramos-e-Silva,MárciaAtualmente, os histiócitos não são mais compreendidos como células únicas, mas como um grupo heterogêneo de células com o mesmo aspecto histológico, mas com características e funções distintas entre si. Várias doenças proliferativas de histiócitos, conhecidas como histiocitoses, são descritas. Tais doenças são raras, e seu estudo costuma ser difícil. Este artigo objetiva simplificar o entendimento desse grupo d...
