ABSTRACT
A toxina botulínica tem como mecanismo de ação a paralisia neuromuscular flácida transitória. Estudos recentes estão identificando novas formas de uso da toxina botulínica para diversos fins, tanto no campo estético quanto no terapêutico. Este trabalho teve como objetivo realizar uma revisão bibliográfica sobre essas aplicações. No âmbito estético, a toxina botulínica demonstrou benefício em tratamento de cicatrizes hipertróficas, rejuvenescimento da região escrotal, definição do músculo gastrocnêmio e sendo usada em microdoses. Já no tratamento de patologias, a revisão demonstrou que a toxina botulínica pode ser útil para tratamento da neuralgia pós-herpética e de outras síndromes álgicas, da hiperidrose craniofacial, da rosácea e da doença de Hailey-Hailey.
Botulinum toxin has transient flaccid neuromuscular paralysis as its mechanism of action. Recent studies are identifying new ways to use botulinum toxin for a variety of purposes, both in the aesthetic and in the therapeutic field. This work aimed to conduct a literature review on these applications. In the aesthetic field, botulinum toxin has shown benefit in the treatment of hypertrophic scars, rejuvenation of the scrotal region, definition of the gastrocnemius muscle, and microdoses use. In the treatment of pathologies, the review has shown that botulinum toxin may be useful for the treatment of post-herpetic neuralgia and other pain syndromes, craniofacial hyperhidrosis, rosacea, and Hailey-Hailey disease.

Abstract: Blue nevus is a benign melanocytic lesion, typically asymptomatic and of unknown etiology. Many histological subtypes are recognized, the most commons being: common blue nevus, cellular blue nevus, and combined blue nevus. New rare variants have been described in the literature, with emphasis on eruptive blue nevus, plaque, agminate, linear, with satellitosis, disseminated, familial and targetoid. The diagnosis of blue nevus usually presents no difficulties, however, the presence of structures such as irregular edges or satellitosis, are highly suggestive of malignancy, and the differential diagnosis with malignant blue nevus and melanoma with peripheral spread should be considered. We report a case of blue nevus with satellitosis in a 15-year-old female patient.
