Giant congenital melanocytic nevi: 40 years of experience with the serial excision technique.

Although giant congenital melanocytic nevus is a rare lesion, it causes significant deformity and carries a risk of malignant degeneration. Different surgical techniques for the lesion removal are described, including serial resection, resection with skin grafting, and resection and coverage with expanded skin flap (skin expanders). The aim of this study is to report the author's 40 years of experience with cases requiring at least 4 serial excisions to complete the treatment. Serial resection is an effective, safe, and simple technique that requires a lot of patience. Treatment often results in a single linear scar, requires no donor sites, nor large flaps. It is not subject to potencial complications of expanders and avoid aesthetic deformities depending on the location.

Giant atypical lipoma.

Liposarcomas correspond to the most common histological subtype of soft tissue sarcomas. They can be subdivided into: well differentiated or atypical lipoma, undifferentiated, myxoid, round, and pleomorphic cells. Atypical lipomas are the most prevalent and usually appear as asymptomatic softened tumors. They are locally aggressive but rarely lead to distant metastases. The diagnosis of this tumor is based on the imaging and histopathologic findings. Treatment consists of excision surgery with complete tumor removal. It has a good prognosis due to the low percentage of distant metastases. We report a rare case of giant atypical lipoma as well as the adopted therapy and evolution.

New drugs, new challenges for dermatologists: mucocutaneous ulcers secondary to everolimus.

Everolimus, a mammalian target of rapamycin inhibitor, is an emerging drug, which is being increasingly applied in oncology and solid organ transplantation. Oral ulcers are a frequent side effect associated with this immunosupressor. We report the case of a renal transplant recipient who developed disfiguring oral and perianal ulcers secondary to everolimus's toxicity. This is probably the first report of perianal involvement. Dermatologists need to be aware of the potential mucocutaneous adverse effects related to these new drugs that are becoming evermore common in our clinical practice.

Tratamento não invasivo com ultrassom não focado transcutâneo na redução do tecido subcutâneo abdominal / Non-invasive treatment with transcutaneous non-focused ultrasound for the reduction of abdominal subcutaneous tissue

Introdução: O ultrassom não focado é alternativa não invasiva para melhora do contorno corporal. Métodos: São relatados cinco casos tratados com oito sessões semanais de ultrassom não focado no abdômen. Resultados: O tratamento não interferiu na rotina dos pacientes, tendo sido considerado confortável e seguro. Houve redução na espessura do subcutâneo avaliado por ultrassom e nas medidas circunferenciais em todos os pacientes, com melhora clínica evidenciada na documentação fotográfica principalmente nos pacientes com subcutâneo de baixa espessura. Conclusão: O tratamento se mostrou seguro, com evidências de redução do tecido subcutâneo abdominal.

Introduction: Introduction: Not focused ultrasound is a noninvasive alternative to improve body contour. Methods: It's reported five cases treated with eight weekly sessions of not focused ultrasound on the abdomen. Results: The treatment did not affect the routine of patients; it was comfortable and safe for most. There was a reduction in the thickness of the fat layer evaluated by ultrasound and in the circumferential measures in all patients, with clinical improvement evidenced in the photographic documentation especially in patients with lesser thickness of subcutaneous. Conclusion: The device was safe, and was shown clear reduction in abdominal subcutaneous tissue.
