Zoon''''''''s balanitis is a benign chronic inflammatory lesion of unknown etiology. This article reports the case of a 66-year-old male patient who presented a 2-year history of a erythematous plaque located on the glans penis. The lesion had not been very responsive to conservative topical treatment with corticoid. A significant reduction in the plaque''''''''s size and an improvement in the pruritus was observed with the use of fractional CO2 laser combined with fusidic acid. The treatment was well tolerated and easy to carry out, and improved the patient''''''''s quality of life.

Platelet-rich plasma has been proven to be promising in regards to its applicability in dermatology, especially in the healing of chronic ulcers and for soothing signs of aging. The autologous platelet-rich plasma is obtained through blood centrifugation, in a way that its components are separated by density gradient. The final product is a gel rich in growth factors that act in tissue repair, activating fibroblasts and inducing the extracellular matrix remodeling.

Introduction: Introduction: Androgenic alopecia is the most common type of alopecia. It is characterized by alterations in the hair cycle, leading to progressive follicular miniaturization. Platelet-rich plasma, promotes angiogenesis in the tissue by action of growth factors, which stimulate the hair follicle Objective: To eveluate the hair growth in androgenic alopecia, through cell stimulation performed with the subcutaneous injection of platelet-rich plasma. Methods: Three injections of platelet-rich plasma were performed in 18 patients, at 21-day intervals.The evaluation was performed through comparative clinical photographs, dermoscopy, as well from responses to questionnaires. The Mann-Whitney test and Wilcoxon test were used to analyze the results. Results: For seven women who completed the study, the average improvement was 42.85% (patients) and 35.71% (external observer). For the 9 males, the average improvement was 25.55% (patients) and 18.88% (external observer). In Dermoscopy were observed thickening of hairs, improved local circulation and increased number of follicles. Conclusions: An effective and satisfactory response in androgenic alopecia was verified in relation to the platelet-rich plasma injection technique.

Introduction: Male androgenetic alopecia, has high prevalence and causes great discomfort in patients. The platelet-rich plasma generates an environment acts to create a suitable microenvironment for tissue repair and possibly prolongs the anagen phase of the hair follicles.
Objective: To evaluate the safety, efficacy and viability of the PRP use for the treatment of male androgenetic alopecia. Methods: We selected 08 male patients with androgenetic alopecia. Participants had the side of the scalp randomized scalp to receive PRP or placebo. 3 were performed monthly applications.
Results: Patients who received treatment realized some degree of improvement especially as regards the fall. The results were obtained through the analysis dermatoscopic was evaluated as "trichoscale". We observed an increase of anagen hairs, down telogen hairs and vellus wires and increase terminal wires. The results were statistically significant as the reduction of vellus wires and increase of terminals wires.
Conclusions: This study showed a clinical improvement observed for photos as well as positive results documented by analysis "trichoscale". There was statistical significance of data obtained especially after the first month of treatment.

Alopecia areata can cause significant psychological problems due to the unpredictable nature of the disease, which results in hair loss. We report the case of a patient presenting alopecia areata of difficult treatment, with satisfactory response after intralesional applications of corticosteroid, but that showed recurrence and atrophy; it was then decided to perform intralesional applications of platelet-rich plasma, with improvement of the condition. The technique showed good results in this isolated case, proving to be a potentially useful therapy in the treatment of alopecia areata.

Introduction: Acne is a multifactorial disease where inflammatory lesions usually appear as papules, pustules and comedones. It is more common in people aged between 11 and 30 years, and occurs in various body sites where there are high concentrations of pilosebaceous glands. Acne has different classifications and treatments. More recently, platelet growth factors have been used as an alternative therapy for acne scars.
Objective: The present study is aimed at describing a case of nodule-cystic acne and acne scars Grades 1, 2 and 3b treated with platelet rich plasma and highlighting the effectiveness of the treatment.
Methods: Platelet rich plasma was applied for three months in the left side of the face of a patient bearing acne.
Results: In the clinical and photographic evaluations, there was improvement in the skin appearance and quality, less number of lesions and decrease of pain.
Conclusions: The present study has demonstrated the effectiveness of platelet rich plasma as a treatment for acne and resulting scars.

The present study is a scientometric analysis aiming to verify the scientific production about radiofrequency in facial wrinkles. The databases used were the Web of Science and Pubmed. We searched the literature for all articles with the terms "Radiofrequency", "Facial", and "Wrinkle" in the title, abstract, or keywords. For each study, we analyzed the following scientometric indicators: publication number per year, name of the journal, authors, impact factor, country of publication, and type of study.

Histological data on microscopic treatment zones are essential for evaluating procedure safety and effectiveness. To date, no studies have histologically compared low-temperature plasma with other techniques. In this study, two square areas on the patient's abdomen, referred to as area A and area B, were with low-temperature plasma and fractional CO2 laser, respectively. A biopsy was taken immediately after treatment. When applied to thinner skin regions, plasma technology appears to result in fewer complications, a faster recovery, and fewer side effects during the application period. However, further studies are needed to confirm these findings.
