Introduction: Skin cancer is the most common type of neoplasia in humans, with ultraviolet radiation being considered the main cause. Basal cell carcinoma is the most frequent cutaneous neoplasia, and photoprotection is seen as the most effective measure in its prevention. Nonetheless, there is still some resistance to the use of sunscreens among the general population. There is also a lack of reports in the literature on whether such resistance differs in patients with basal cell carcinoma. Objectives: To evaluate whether there is change in habits regarding exposure to the sun and use of sunscreen after diagnosis of basal cell carcinoma in patients treated at the Dermatology Outpatient Clinic of Universidade Federal de Ciências da Saúde de Porto Alegre (RS), Brazil. Methods: A cross-sectional study was carried out with 120 patients diagnosed and treated for basal cell carcinoma, who responded to a questionnaire regarding their sun exposure habits and use of photoprotection methods before and after diagnosis. Results: Of the 120 patients interviewed, 73.3% reported changes in their habits regarding exposure to the sun and use of sunscreen after receiving a diagnosis of basal cell carcinoma. The main reasons alleged by those who denied having changed their behavior towards sun exposure (26.7%), were the lack of fear of new tumors, as well as the high cost of sunscreens. Conclusions: A diagnosis of basal cell carcinoma motivates most patients to improve their use of preventive measures regarding protection from the sun. Nonetheless, about a third of the studied population still resisted such measures, the main reason cited being the high cost of sunscreens. Therefore, awareness campaigns about the importance of using photoprotection methods to prevent skin cancer must be implemented, and the development of programs aimed at making sunscreens available to the general population – especially to high-risk patients – must be sought.

The reconstruction of defects resulting from tumor resection is a challenge for the surgeon, who should get good results both functional and aesthetic. The objective of the present study is to describe the surgical technique used in a 78-year-old male patient with the diagnosis of squamous cell carcinoma in the lower lip and who underwent excision of the lesion and reconstruction with the Karapandzic technique. This flap is employed in the reconstruction of surgical defects that cover 40-75% of the lip's extension.

Introduction: The lower eyelid is often the site of basal cell carcinomas, with Mohs micrographic surgery (which allows precise histological control with maximum tissue preservation) being the ideal method for their treatment. Tumors that invade the posterior lamella cause full-thickness defects of the lower eyelid, for which several reconstruction techniques have been described with composite grafts. However, few authors use the helix of the ear as a donor area. Objective: To describe the applicability of ear helix composite grafts in the reconstruction of the lower eyelid. Methods: Retrospective study of a series of 6 cases of basal cell carcinoma in the lower eyelid, with tarsal invasion, operated through Mohs micrographic surgery in a private specialist service in the city of Rio de Janeiro, Brazil. All patients had full-thickness defects, and had undergone reconstruction of the posterior lamella through chondroperichondrial graft of the ear helix. The anterior lamella was reconstructed with the remaining eyelid tissue mobilization or with an advancement flap. Patients were assessed for functional capacity and aesthetics. Results: There was complete adaptation of the perichondrium to the conjunctiva, after contact with the eyeball for 8 weeks. All patients with mild escleral show without ectropion. Conclusions: Despite the small sample, all patients had excellent cosmetic and functional results.

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.

Introduction: Successful restoration of form and function of the nose after Mohs surgery requires thoughtful reconstructive planning. Nasal defects that are deep and extensive, especially those located on the ala, may require a cartilage graft to help restore nasal function, anatomy, and cosmesis. Objectives: To evaluate the usefulness of auricular cartilage grafts in nasal reconstruction after Mohs micrographic surgery, as well as to describe a cartilage graft harvesting technique. Methods: Retrospective study of patients with nasal defects following Mohs surgery who were submitted to an auricular cartilage graft. Results: Ten patients were included in the study. The cartilage graft was harvested from the scaphoid fossa/antihelix in six (60%) patients, and from the concha in four (40%) patients. All scaphoid fossa/antihelix cartilage grafts were harvested through anterior incision, while conchal grafts were removed through posterior incision. One patient developed a hematoma, which drained spontaneously. Conclusions: auricular cartilage grafts are a versatile, reliable, and predictable method of providing structural support in nasal restoration. It is crucial to identify patients who can benefit from this technique. Through careful planning and adequate execution, ear cartilage grafts help to improve nasal reconstructions results in selected cases.

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.

Basal cell carcinoma is the most common type of cancer and its non-surgical treatment has been the subject of many studies. Large lesions of this tumor are therapeutic challenges and the effective topical treatment has good applicability. The authors present a female patient diagnosed with multicentric superficial basal cell carcinoma in the lumbar region for more than 20 years, who refused to be treated surgically. The tumor reached dimensions of 12 cm x 10 cm. A decision was made for a non-surgical therapy, with the application of Imiquimod in a treatment of 5 weekly applications for 2 months. The treatment led to a clinical and histological cure, without recurrence to date (36 months), with excellent aesthetic results and few side effects.

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.

Basal cell carcinoma corresponds to the majority of malignant cutaneous malignancies in Brazil, predominating in middle-aged white individuals, mainly affecting the upper two-thirds of the face and occurring due to several etiological factors. The ideal treatment consists of complete removal with free lesion margins. For better functional and aesthetic results, reconstruction of the surgical wound with flaps or grafts may be necessary. Two types of reconstruction are described in patients with double surgical defects on the face, close to each other: one with a single rotation flap and another with a double rotation flap, also called Yin-Yang.

Reconstruction of the nasal area is a challenge due to its vascularization and abundance of fibrotic tissue. Graft in a large defect in the nasal area has a high risk of necrosis and often produces deformity and color mismatch. We report the case of a 65-year-old man with basal cell carcinoma in the left nasal ala. Mohs surgery was performed, obtaining free margin. The final defect measured 2 cm in diameter with partial loss of skin thickness. The combination of a melolabial interpolation flap and an ear cartilage graft was used, with excellent results. This combination led to good structural and aesthetic results.

Basal cell carcinoma (BCC) is more common in the lower eyelid region when it affects the periorbital region. It occurs predominantly in men between 50-70 years and has a high recurrence rate. Although it rarely metastasizes, orbital invasion can occur. This study aims to present a case of pigmented BCC of unusual location. The location of BCC in the upper eyelid region is rare, and dermoscopy is essential to distinguish it from its primary differential diagnoses.

The recurrent squamous cell carcinoma (SCC) needs an appropriate approach to decrease the risk of recurrences. We report the case of a man diagnosed with SCC on the left temporal region treated by conventional surgery, with infiltration and erythema in the scar area. Reflectance confocal microscopy suggested the diagnosis of recurrent SCC confirmed by histopathology. New surgery and traditional intraoperative frozen section were performed. After two months, the patient had a new relapse, finally treated with Micrographic surgery without new involvement. This article highlights the importance of micrographic surgery in treating SCC, aiming to decrease new recurrences.

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.
