Introduction: Mohs micrographic surgery is a technique that offers high cure rates for non-melanoma skin cancer.
Objective: To describe the clinical and epidemiological profile of patients who underwent Mohs micrographic surgery in a reference center in dermatologic surgery.
Methods: Medical records of patients who underwent Mohs micrographic surgery in the period 2014-2015 at a dermatology reference center, in the city of Mogi das Cruzes (SP, Brazil), were analyzed.
Results: The patients' ages ranged from 38 to 87 years; of these 54% were women. The most affected topography was the nose (54% of patients). Previous history of skin cancer was positive in 62% of cases. The indication driver for micrographic surgery was the lesion's location in 67% of the patients, followed by the size (23%) and tumor recurrence (10%). The most prevalent intraoperative diagnosis was basal cell carcinoma (90%).
Conclusions: Mohs micrographic surgery is an excellent therapeutic option in cases of tumors of aggressive nature, large diameter and high-risk location. This study is in line with the current literature regarding the epidemiological data linked to the occurrence of nonmelanoma skin cancer.

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.

Systemic sclerosis (SE) is an autoimmune disease of the connective tissue. Of unknown etiology, it is characterized by sclerosis (fibrosis), which affects the skin, blood vessels and internal organs. The diagnosis is confirmed by a compatible clinical picture, autoantibody research and capillaroscopy of the nail bed. The present report highlights the importance of the dermatologist physician in the diagnosis of systemic diseases. Based on the observation of the skin – which is visible and palpable in all of its dimensions – and in the interpretation of all its signs, it is possible to conclude that it can reveal early internal disorders that could develop unnoticeably.
