Introduction: Liposuction is a cosmetic procedure that removes undesired body fat. More recently, it has been associated with complications and deaths, raising concerns about the risk involved in the procedure. Since the tumescent technique was described by Jeffrey Klein, surgeons from around the world have contributed to the development of the technique, making liposuction with microcannulas and local anesthesia a safe and effective procedure that achieves its objective. Nevertheless, severe complications and deaths are described in the literature when the procedure is performed under general anesthesia or with IV drugs, or when there is a breach of the protocols recommended for local tumes- cent anesthesia. Therefore, it is necessary to establish protocols for liposuction procedures that use local tumescent anesthesia, to promote safety.
Objective:To demonstrate that using local tumescent anesthesia in liposuction is safe.
Methods: Retrospective study of medical records of 568 patients who underwent 1,107 liposuction procedures assisted by local tumescent anesthesia between 1998 and 2004.
Results: There were no deaths or complications that required hospitalization.
Conclusions: When standardized protocols are observed, liposuction assisted exclusively by local tumescent anesthesia was shown to be a safe procedure.

Introduction: Laserlipolysis is an emerging technique in the treatment for localized fat and Skin tightening. This therapy has a shorter post-operative recovery time and fewer adverse effects than conventional liposuction.
Objective: This study describes the authors’ experience in laserlipolysis and evaluates the technique’s safety and efficacy.
Methods: Retrospective study of 120 patients who underwent laserlipolysis, which was administered via two devices with different wavelengths: 1064-nm Nd:YAG laser and 924 nm/975 nm diode laser.
Results: According to clinical and photographic follow up, there was a significant improvement in localized fat in the definition of the body’s contour and in the skin tightening in all studied patients; 108 patients were satisfied with the technique. There were no cases of atrophic scars, hyperpigmentation, hypopigmentation or infection.
Conclusions: If properly recommended and carefully carried out, laserlipolysis is a safe and highly satisfactory option for the treatment localized fat and sagging skin.

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.
