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.

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.

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.

Cutaneous diffuse large B-cell lymphoma, leg type, is a rare, aggressive, and poorly prognostic neoplasm. It corresponds to 10-20% of cutaneous B-cell lymphomas and mainly affects the lower limbs of older women. We report the case of an 81-year-old woman with painful, fast-growing nodules and tumors in her left leg. Histopathological and immunohistochemical findings, associated with the absence of extra-cutaneous involvement during staging, concluded the diagnosis of cutaneous diffuse large B-cell lymphoma, leg type. The rarity of this limphoma, its typical clinic and epidemiology, and the excellent response to treatment motivated this report.

Exogenous ochronosis is a stigmatizing dermatosis characterized by asymptomatic, bluish-black, or grayish macules in photoexposed areas. Associated with the prolonged use of hydroquinone for the treatment of dyschromias, it has a broad therapeutic arsenal, but the results are unsatisfactory and/or costly. We report the case of a female patient with histologically proven exogenous ochronosis who underwent dermabrasion associated with the use of tretinoin and topical corticosteroids with surprising results after three months of follow-up to demonstrate the possibility of therapeutic success with a low-cost technique and an outpatient clinic procedure.
