Introduction: Obesity is a major health problem worldwide due to its high morbidity and mortality. Objective: To evaluate the reduction of abdominal fat in volunteers who underwent low-frequency diode laser therapy. Methods: A total of 60 volunteers (18 to 50 years of age, with a BMI of between 18.5 kg/m2 and 30 kg/m2, and who had abdominal fat), underwent a treatment performed twice a week for 31 days and were then evaluated. The abdominal circumference was evaluated in three locations, with photographic and ultrasound images taken of the studied area. Results: There was a reduction in the abdominal circumference measurements in the evaluated sites, with dermal compression and a significant reduction of hypodermis verified through ultrasound. Conclusion: The low-frequency diode laser therapy showed significant results in the reduction of localized fat and abdominal circumference measurements.

Alopecia areata is a relatively common autoimmune condition. It has an unpredictable course and its etiology has not yet been fully elucidated. Its treatment must be individualized, and aims at suppressing the phase of activity of the disease. Thus, many alternatives are available; however, none of them have been curative or preventive so far. We report the cases of two patients, aged 18 and 43 years, diagnosed with alopecia areata, who underwent topical immunotherapy with diphencyprone, and obtained different results. The application procedures, the results obtained and the clinical follow-up are described.

Angiosarcoma is a rare and aggressive vascular neoplasia that can occur anywhere in the skin integument, especially in the face and scalp. It has a branched character, and can clinically arise as a macula, papule, plaque or nodule of erythematous hue, with imprecise limits and expansive growth, and diagnosis based on the clinical-pathological correlation. In the present study, the authors report the case of a patient with exuberant cutaneous angiosarcoma on the face, where surgical resection was performed as the first therapeutic option.
