The reconstruction of nasal surgical defects, especially when there is total thickness bilateral simultaneous involvement of the nasal ala, tip, and dorsum, is complex. Several surgical options are described, and most authors recommend ear cartilage graft or chondro-mucous flap of the nasal septum, associated with the frontal median flap in order to lend structural rigidity to the nasal ala, preventing it from collapsing during inspiration. The authors describe an alternative reconstruction technique without the use of cartilage through the combination of hinge flaps from the nasogenian fold, associated with a frontal paramedian flap.

In search of a perfect aesthetic, facial filling procedures have been widely used. The presence of animal proteins or synthetic substances in some cutaneous fillers can cause serious allergic reactions, especially when performed by untrained professionals. There are not ideal, pure and free of side effects substances available in the marketplace. The present article is aimed at reporting a case where a facial filling was performed by a non-medical professional, resulting in foreign body reaction and severe skin infection, leading to deformities caused by the procedure carried out. The complications entailed invasive procedures for removal of the material used, and treatment with corticosteroids.

The basal cell and squamous cell carcinomas are known as non-melanoma skin cancers, having amounted to 98,420 new cases in men and 83,710 in women in Brazil in 2014. The reconstruction of surgical defects in the nose is a challenge for dermatologic surgeons regarding good functional and aesthetic results, since its structure is rigid and of little mobility. The authors introduce an interesting reconstruction method of a large nasal defect after excision of a basal cell carcinoma, using auricular cartilage graft and unipedicled advancement flap from the lower cheek.

Introduction: Hyperhidrosis is a common disease characterized by excessive sweating. Several treatment options are described as axillary liposuction and laserlipolysis.
Objective: To compare the effectiveness of two treatment methods for axillary hyperhidrosis – one exclusively surgical (liposuction) and the other employing invasive laser therapy (laserlipolysis) – using a prospective, comparative study with a one-year follow up.
Methods: Liposuction was carried out in the right axilla, while laser lipolysis was performed in the left axilla. The evaluation was conducted using the starch-iodine test, comparative histological analysis and patient self-assessment questionnaires.
Results: Twelve patients took part in the study. The starch-iodine test indicated decreased sweating in all patients within one year after the procedures, while the histological analyses showed absence or reduction of the secreting ducts and acini on both sides and in all cases. After one year of follow-up, the patient's satisfaction index measured by the questionnaires remained positive in all cases, with 75% asserting maximum satisfaction, and 25% reporting difference between the sides (better results were described in the right hand side axilla).
Conclusions: Both techniques showed similar effectiveness after one year of follow-up. Laserlipolysis had a lower frequency of postoperative complications.

Introduction: Molluscum contagiosum is a dermatovirosis caused by a poxvirus. In the literature there are descriptions of different therapeutic approaches of this infection.
Objective: To evaluate the efficacy of imiquimod – isolated and associated with curettage – in the treatment of molluscum contagiosum.
Methods: Group A: 20 patients used 5% imiquimod cream 3 times a week for 6 weeks. Group B: 10 patients used a creamy base 3 times a week, for 6 weeks. After the initial 6 weeks, all patients underwent curettage.
Results: Group A: 31% decrease in the number of lesions in the 6th week, with a curettage effectiveness of 97.6%; Group B: 4.8% increase in the number of lesions in the 6th week, with a curettage effectiveness of 81.1%. The mean value for the pain level during curettage was 1.8 for Group A and 3.0 for Group B.
Conclusions: Due to the facts that the rate of cure of contagious molluscum lesions increased and the pain decreased when the curettage procedure was conducted after the use of the immunomodulator, it was possible to conclude that the association of 5% imiquimod cream to the curettage may be a therapeutic possibility.

Among the diverse reconstruction alternatives used in surgical wounds, those employing cutaneous grafts are implemented when the closure – primary or by second intention – is unfeasible or, due to other factors, flaps are not recommend. The repair of surgical wounds using partial thickness graft obtained from the scalp with a flexible blade is described in 3 cases of conventional exeresis (2 basal cell carcinomas in the nasal region and 1 case of squamous cell carcinoma on the dorsum of the hand). The technique yielded good aesthetic outcomes, both in the receiver and donor areas.

Non-melanoma skin cancer is the most common neoplasia in humans, and basal cell carcinomas (BCC) account for approximately 80% of cases. Cumulative exposure to ultraviolet radiation (UV) is the main risk factor associated to BCC, with a higher incidence in photoexposed areas, including the auricular region. The auricular region is a noble cosmetic unit, with anatomical peculiarities that lead surgeries to require the excision of a large amount of tissue, presenting a challenge for the dermatological surgeon. The authors present a case of helix reconstruction with a triple transposition flap.

The nasal region is often affected by cutaneous neoplasm, especially in individuals of low phototypes, where the incidence of basal cell carcinoma is high. Surgical defects in the nasal wing and perinasal region constitute a challenge to its reconstruction since it involves several cosmetic units and preservation of the nasal groove. The preservation of the limits between these units is thus fundamental for good functional and aesthetic results. This article aims to show the application of the Shark Island Flap for the correction of defects in the nasal and perinasal regions.

The lower eyelid is one of the sites most affected by basal cell carcinoma (BCC). We present an option of inner corner skin flap with oral mucosa graft for eyelid reconstruction after BCC excision. This tumor affects approximately 60% of the lower eyelid and shows complete lower lacrimal canaliculus involvement. The use of internal corner skin transposition flap and oral mucosa graft is safe. The technique is reproducible and with good postoperative evolution. Positioning and eyelid movement were restored, allowing tear drainage through the upper canaliculus with complete correction of the tears’ overflow (epiphora).

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 nasal defects secondary to non-melanoma skin cancer represents a surgical challenge, especially in the nasal tip, due to its limited local laxity and possible asymmetries. There are multiple techniques to perform this closure, but most are flaps from distant locations that can lead to less aesthetic results. We present two cases of basal cell carcinoma on the nasal tip, where reconstruction with the east-west advancement flap was performed after tumor excision, with a modification of the flap in one of the patients, obtaining a good structural and aesthetic result.

The closure of large defects on the nasal dorsum is a challenge for dermatologic surgeons. The alternatives to repair the defect are a skin graft and some forms of skin flaps. One particular defect closure technique is the crescentic advancement flap, which uses crescent incisions at the nasolabial fold to accommodate the excess tissue. This flap is best used if the defect is in the lateral nose, alar, and nasolabial fold. We report a large defect of the nasal dorsum in a 65-year-old woman that was successfully reconstructed using bilateral cheek-to-nose crescentic advancement flap. The patient showed excellent cosmetic and outcome.

A wide range of dermal fillers is now available for use in the beauty industry. We present a case of a 33-year-old woman with complications after hyaluronic acid injection by a non-medical practitioner. Two weeks after the injection, bilateral sinus pain, fever, and burning sensation occurred in the cheek area. She underwent a detailed diagnosis revealing Attagenus larva in the paranasal sinus. Despite treatment, the symptoms remained. Thus, hyaluronidase was administered in the infraorbital area, obtaining a full remission.

Rhinophyma is characterized by chronic inflammation of the tissues of the nose, resulting in irregular exophytic growth and telangiectasias. The disease progresses with hyperplasia and hypertrophy of the nasal sebaceous glands, associated with fibrosis and dilation of local blood vessels and connective tissue. These changes can lead to complete nose deformity and compromise the patients' quality of life. There are different treatment methods, such as laser, microdermabrasion, chemical exfoliation, cryosurgery, surgery with skin graft, and electrosurgery, with varying results and costs. We report two cases of rhinophyma treated with electrosurgery with very satisfactory results.
