Post-adjusted M-plasty can be used in any surgical defect that can be closed by direct approximation of the borders to avoid the formation of apical protrusions. It is performed without prior planning; the tissue is removed only if the surgeon detects a protrusion during surgery. This method offers the advantage of sparing healthy tissue by adjusting the incisions to each patient’s skin’s tension lines, wrinkles and junctions of cosmetic units, in addition to the possible use of the “M”s pedicle as a small advancement flap. This study describes the procedure step by step, highlighting the differences and advantages compared to traditional M-plasty.

Flaps are widely used in the surgical reconstruction of the nasal region. During the post-operative period, an unattractive depressed scar in relation to the nearby skin can be observed. Even after abrasion – which the literature recommends 30-60 days after the procedure – this complaint often persists. This study proposes tangential excisions with a razor blade (shaving) of the flap''''''''s entire area until it is level with the surrounding region, followed by dermabrasion to refine any remaining irregularities. The results are deemed excellent since the scars become less noticeable – a very satisfactory outcome due to the aesthetic and social importance of the treated area.

The dorsum of the hand is home to tumors that often require a surgical approach. Due to limited cutaneous mobility, wide surgical wounds become a challenge to dermatologic surgeons. The authors report the case of a patient with a tumor in the dorsal region of the left hand that, after removal with a safety margin, resulted in a wide surgical wound, and in the choice of reconstruction with an A-T flap. Six months later, the patient was cured, with total preservation of the hand's mobility and excellent aesthetic results. The concept of using flaps for closing wide surgical wounds, whenever possible, is reinforced.

Eccrine spiradenoma is a rare benign adnexal epithelial neoplasm characterized by a bluish-pink, slow-growing solitary nodule, coursing with paroxysmal pain, mainly in young adults. It is most commonly located in the trunk and extremities. Bleeding and/or ulceration are common in the giant vascular variant, which is characterized by a size greater than 2 cm in diameter and a high degree of vascularization seen on histology. Its clinical characteristics are unspecific and require biopsy with histological analysis for diagnosis. Its histology presents one or more basophilic intradermal lobules enveloped in a fibrous capsule without connection to the epidermis. It presents two types of cells: small cells with dark nuclei in the periphery and large cells with light nuclei in the center. An accurate diagnosis is important due to the fact that it can develop into a potentially fatal malignancy - which is a rare phenomenon and occurs most often in the multiple variant. A rare case of eccrine spiradenoma in the abdomen with bleeding associated is described in the present paper, as well as a discussion on possible treatments.

Endometriosis is a common dermatosis that most typically affects the pelvic organs. Extra-pelvic occurrences are reported in the literature. Umbilical endometriosis is rare and can be primary (spontaneous) or secondary (after surgery). The present study describes the case of a female patient with endometriosis lesions in the umbilical region, confirmed by histology. Treatment was carried out with wide surgical excision. It is important to note that differential diagnosis should be considered in the presence of umbilical tumors in women of reproductive age.

Introdução: A non-invasive alternative for the treatment of localized fat is cryolipolysis that, by freezing adipocytes, reduces fat volume in the region where the procedure was performed. Objective: To statistically describe the experience of a referral center for this procedure. Methods: A cross-sectional study with 251 patients undergoing cryolipolysis was carried out with the epidemiological analysis of patient data. Results: Thirty-eight males and 213 females underwent the procedure, with a total number of 740 treated areas. The anterior abdomen (lower third) was the most popular region, with 45.30% of cases. Eighty-eight percent were satisfied or very satisfied with the result. Nearly all cases required 2 or more sessions to achieve this degree of satisfaction. Conclusions: Cryolipolysis is a noninvasive method for the selective reduction of fat that has shown efficacy in reducing the subcutaneous tissue, with minimal and reversible side effects in this study.

Introduction: Low level laser therapy has been considered a non-invasive treatment alternative to body remodeling and fat tissue reduction.
Objective: To evaluate the efficacy of low level laser therapy in reducing body circumference measures and subcutaneous adipose tissue of the abdomen and hips areas.
Methods: An open, prospective, monocentric study was performed including 25 women with localized fat on the hips and abdomen. Nine sessions of low level laser therapy were performed over 3 weeks. The participants were assessed at baseline and at 1, 4 and 12 weeks after treatment. Assessment of weight and body circumferences, lipid profile tests and MRI were performed.
Results: The abdominal circumference measurements showed a significant reduction up to 12 weeks after the treatment. Participants showed a more marked reduction in the hips region one week after the last session. Also one week after the completion of the treatment, 80% of the participants considered that the treatment improved their body contour. There was absence of reports of adverse events related to the treatment.
Conclusion: Low level laser therapy is safe and effective in reducing the circumference measurements, particularly in the abdominal region.

O queratoacantoma (QA), apesar de frequente na prática diária, é um tumor que gera questionamentos. O aspecto mais intrigante associa-se à sua posição no limite entre malignidade e benignidade. A abordagem do tumor, bem como sua classificação, é controversa. Na definição da conduta, é importante levar em conta o potencial de transformação para carcinoma espinocelular. Desse modo, a excisão cirúrgica é a terapia de escolha, sempre que possível. Algumas situações merecem atenção adicional, como a imunossupressão associada. Neste artigo, relatamos um caso de QA gigante em um paciente com síndrome da imunodeficiência adquirida tratado com cirurgia micrográfica de Mohs.

The reconstruction of deep surgical defects of the nasal tip and wing of the nose often presents a challenge to the surgeon. In these cases, full-thickness skin grafting is widely used, but it often results in sinking or graft depression. We present a surgical technique that is easy to perform and reproducible; nonetheless still very little diffused in Brazil: the “Drumhead” graft. This method performs the grafting of a rigid plastic suspension together with the full-thickness skin graft. Thus, this technique constitutes another tool for the dermatological surgeon to prevent irregularities of undesirable contours, graft depression, and nasal vestibule collapse.

INTRODUCTION: The perioral region is commonly affected by non-melanoma skin cancer. Mohs micrographic surgery is the treatment of choice in this area because it has the highest cure rate and preserves healthy tissue. Several methods are available for restoring the perioral region, and their selection is influenced by the surgical wound characteristics and the surgeon's preference.
OBJECTIVE: Describe the authors’ experience in perioral reconstruction after Mohs micrographic surgery and analyze the repair methods most frequently performed.
METHODS: Retrospective study of consecutive cases submitted to Mohs surgery and perioral reconstruction.
RESULTS: The study included 108 cases from 103 patients. The mean number of Mohs surgery stages was 1.4, and the mean defect size was 16 mm. Primary closure was the most used technique for reconstruction, followed by flaps (mainly V-Y, single advancement, and rotation). The association of repair methods was used in 28.7% of cases, mostly combined with flaps. Four patients had complications (necrosis and graft infection, trapdoor effect, and partial wound dehiscence).
CONCLUSION: Primary closure was the most frequent repair method, followed by flaps. Knowing reconstruction strategies and possibilities of associations is essential for proper restoration of the perioral region, maintaining its functionality, sensitivity and aesthetics.

Localized scleroderma (linear morphea) is a rare disease that causes facial dystrophy and asymmetry in young women. We report the case of a 20-year-old female patient who was treated with novel composite fat grafts. After extracting lipoaspirate from deep subcutaneous fat, the microfat and the unfiltered nanofat were processed separately, and amalgamated, obtaining composite fat grafts. These were meticulously transplanted layer by layer to rebuild the subcutaneous tissue of the patient's face. After one year, a good volume of fat retention was observed with successful correction of asymmetry and restoration of facial balance.

We report a case of a 72-year-old man who underwent surgical excision of a keratoacanthoma centrifugum marginatum (KCM) located on the left forearm. It is an uncommon variant of keratoacanthoma, which can assume large dimensions (up to 20 cm) and does not tend to spontaneous regression. The lesion is usually single, with raised borders, and has progressive centrifugal growth associated with central healing and atrophy. Due to its rarity and lack of pathognomonic histopathological features, KCM can be a diagnostic challenge for dermatologists and pathologists.
