Introduction: Skin cancer is the most common type of cancer in the world. It is classified into melanoma (corresponding to 4% of cases) and non-melanoma types: basal cell carcinomas (70 to 80% of cases) and squamous cell carcinoma (25% of cases). The Brazilian Society of Dermatology conducts the National Campaign Against Skin Cancer on a yearly basis, aiming at diagnosing and providing early treatment to the neoplasia.
Objective: To demonstrate the incidence of lesions suspicious of skin cancer in selected patients originated from the 2016 National Campaign Against Skin Cancer, at the dermatologic clinic of a university hospital located in the Brazilian State of São Paulo’s midlands.
Methods: Two hundred and thirty patients were examined, of which 24 were selected with 22 undergoing biopsy of the suspected lesions.
Results: Sixteen basal cell carcinoma cases, one squamous cell carcinoma and one melanoma were confirmed through anatomopathology.
Conclusions: Notwithstanding the small sample, it was possible to conclude that the results found are compatible with those of the literature reviewed. It is of paramount importance to carry out the campaign as a way to streamline the population’s access to a dermatologist, which results in the early diagnosis and treatment of skin cancers.

Introduction: Rosacea is a chronic facial condition characterized by erythema, edema, telangiectasias, papules and possibly pustules and nodules. There are four subtypes: erythematous-telangiectatic rosacea (I), papulopustular rosacea (II), phymatous rosacea (III) and ocular rosacea (IV). Its pathogenesis is multifactorial, and the treatments, diverse.
Objective: To demonstrate the effect of botulinum toxin in the improvement of flushing and erythema in patients with erythematous-telangiectatic rosacea.
Methods: Six patients with Subtype I rosacea were selected in the Dermatology Department’s outpatient clinic of a university medical service. The patients received applications of botulinum toxin type A (dilution of 100 units to 5 ml of saline solution), with intradermal injections of 0.2 to 0.5 units per point in the affected region. Evaluations were carried out after one, two, three and six consecutive months.
Results: There was improvement of the facial erythema and flushing during the three months following the application, with symptoms returning around the sixth month after the treatment, in line with the estimated duration of toxin effectiveness.
Conclusions: There was improvement of the patients' symptoms and satisfaction, and it was deemed a treatment of easy application, associated with a low index of adverse effects and prolonged duration of outcomes.

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.
