Introduction: Workshops are offered during Dermatological Meetings in order to teach surgical procedures, both live and in detail. Nevertheless, access to post-operative developments, as well as to the results obtained, are restricted to the physicians from the medical services responsible for organizing these events. Objective: To assess, and make known, the progress and results of previously operated cases. Methods: Eight patients with different pre-operative diagnoses were operated on the nail surgery workshop that occurred during the Brazilian dermatological meeting RADESP 2011, with a nine-month follow up. The results were evaluated using photographs, taken every three months, by the surgeons responsible for the surgeries. Results: Of the eight operated cases, two were considered as yielding satisfactory results (one with mild dystrophy of the nail plate and the other with time considered insufficient for better assessment), and five were deemed as cured. One case did not return for the follow-up visits. Conclusion: Following up and presenting the post-operative development of these patients as well as publishing the responsible surgeons' evaluations, complements the knowledge acquired by the workshops' attendees, and that of other participants at the meetings.

Deep phenol chemical peeling with the Baker-Gordon formula is indicated for the treatment of severe facial aging. A review of pertinent literature on its main limiting factor-pain-was carried out with searches on two databases (PubMed and Cochrane Library) using the following keywords: chemexfoliation, peel, peeling, and phenol, also cross-referencing with the terms anesthesia and analgesia. The search resulted in 151 articles that contributed little to clarifying what would be the ideal approach for managing pain when using a deep chemical peel with the Baker-Gordon formula. As a result, for this procedure, the authors basically relied on the expert experience-in this case, that of the anesthesiologist-which has been described. Therefore, further studies should be carried out in order to achieve a higher level of scientific evidence.

The observation of mucous membranes should be part of a dermatological examination. It is known that early diagnosis is critical for the prognosis of patients with malignant melanocytic lesions. Nevertheless, integrating this step into the examination routine and performing a differential diagnosis between benign and malignant mucosal lesions with only clinical signs, are great challenges. Dermoscopy is still seldom-used for pigmented lesions of mucous membranes, however recent studies have shown its potential. In light of a case of melanoma of the lip, the authors provide tips and data from the literature that highlight the usefulness of the technique, and support the use of dermoscopic examination in the dermatologist's routine.

Desmoplastic melanoma is a rare variant of melanoma characterized by an invasive lesion of spindle cells and varying degrees of desmoplasia. It is more frequent in men of an advanced age having a history of chronic exposure to sunlight. The extremely variable and nonspecific clinical appearance makes it a challenging diagnosis. The authors present an exuberant case of desmoplastic melanoma in an unusual location, with an initial diagnosis of dermatofibrosarcoma.

The authors describe the case of a 54-year-old woman presenting papules and yellowish plaques on the right thigh for 15 years, which clinically resembled a plane xanthoma. An anatomical pathological examination evidenced a mature adipose tissue in the dermis, with a diagnosis of superficial cutaneous lipomatous nevus, a rare benign hamartomatous malformation characterized by the presence of ectopic mature adipocytes in the dermis.

Vitiligo is an acquired depigmentation characterized by partial or total loss of epidermal melanocytes. Many therapeutic modalities have been proposed for its treatment. In cases of stable vitiligo surgical treatments are preferred. Grafting by epidermal scraping is a variant of micrografts by punch technique. It is a new, simple and low cost technique, with high rates of repigmentation. The objective of this report is to demonstrate the authors' experience with this technique and discuss the results in an initial series of two cases (three lesions).

Described by Jadassohn and also known as organoid nevus, nevus sebaceous is considered a hamartoma that exhibits follicular, sebaceous, eccrine and apocrine malformations of varying degrees. Between 10% and 30% of patients with sebaceous nevi of Jadassohn are at risk of developing cutaneous or adnexal neoplasia during adulthood. The authors describe the case of a patient with nevus sebaceous of Jadassohn associated with multiple tumors (benign and malignant) of different strains, highlighting the importance of the dermatologist physician’s knowing this entity and how to perform an examination of the scalp.

INTRODUCTION: Healing is a phenomenon that occurs after tissue injury and involves complex cellular and molecular mechanisms. Growth factors seem to be an effective and safe complement for the treatment of wounds.
OBJECTIVE: To evaluate wound healing after electrocoagulation, comparing the vehicle in isolation and its association with epidermal growth factor.
METHODS: Double-blind clinical trial in a Dermatology service between 2016 and 2018. Patients of both genders, older than 18 years of age, submitted to electrocoagulation of two lesions and subsequent application of the vehicle (cold cream) on one and epidermal growth factor in cold cream on the other were included. Evaluations after 7, 14 and 28 days, analysed erythema, edema, crusting, discharge and healing. Analyzed: edema, edema, crusting, discharge and healing. The binomial test was used for two ratios and Fisher’s exact test was used for dichotomic data.
RESULTS: Variable results were found regarding erythema, edema, crusting and discharge, sometimes favoring the vehicle, sometimes the growth factor, however with no statistical significance. Regarding healing, epithelialization was quicker with with epidermal growth factor (p<0.05).
CONCLUSIONS: This study evaluated the impact of epidermal growth factor in the healing process, and its results reinforce scarce data of the current literature and are a foundation for future studies.

Malignant melanoma is a melanocyte tumor responsible for more than 75% of skin cancer deaths. The rare variants of this pathology are responsible for 5% of the cases and may mimic other pathologies. We report the case of a patient with spitzoid melanoma and we discuss the dermoscopic, histopathological, and immunohistochemical findings, as well as the follow-up of this rare variant of melanoma.

INTRODUCTION: Actinic cheilitis (AC) is a premalignant condition resulting from chronic sun exposure that affects the lower lip vermillion. Daylight Photodynamic Therapy (DL-PDT) is a new alternative to conventional therapy, being more straightforward, more accessible, and with better tolerability.
OBJECTIVE: To evaluate the efficacy and applicability of DL-PDT in the treatment of AC and to determine the most prevalent adverse events.
MATERIAL AND METHODS: Experimental study, uncontrolled clinical trial type. The included patients were selected based on clinical and histopathological diagnosis of AC. Aminolevulinic acid was applied to the lower lip, and the sun exposure was conducted (3 sessions/ 2-week interval). We performed pre and post-treatment biopsies, took photographs for documentation, and filled out a default form.
RESULTS: The study included 11 patients (63.6% men); mean age 59 years, and predominance of Fitzpatrick skin phototype II (45.4%). We observed a statistically significant clinical improvement (p = 0.026), but not histologically confirmed. The adverse events were minimal (46% asymptomatic).
CONCLUSIONS: The study evaluated the efficacy and applicability of DL-PDT in the treatment of AC and determined the prevalent adverse events, motivating, and supporting future studies.
