Introduction: Basal cell carcinoma is the most common skin cancer and corresponds to 70-80% of all malignant neoplasms of the skin. It is emerging as a global public health problem, with incidences of the condition increasing in all countries. Objective: To evaluate the epidemiological profile and characteristics of patients diagnosed with basal cell carcinoma in the previous four years in a reference hospital. Methods: A cross-sectional descriptive study was carried out at a dermatology reference center in the city of Bauru, São Paulo State, Brazil. Patients diagnosed with basal cell carcinoma, confirmed by histological examination from January 2010 to December 2013 were included in the study. The variables analyzed descriptively were: age at diagnosis, gender, city of origin, site of lesion, and race. Results: A higher incidence of basal cell carcinoma was observed in Caucasian women older than 60 years, with the malar and nasal regions arising as the usual locations. Conclusions: There is an increased incidence of basal cell carcinoma in young people, however the most affected population is still the elderly Caucasian population. The most common area for the cancer is the face, particularly the upper two thirds. The incidence of this cancer in younger populations is worrying, with the dermatologist having an important role in the prevention and early treatment.

Recurring nevus or pseudomelanoma is a benign melanocytic lesion that appears in the same location after an incomplete surgical removal of nevi. These pigmented melanocytic lesions can in some cases be a diagnostic challenge when examined through dermoscopy, especially if there is a clinical history of growth or recurrence of the lesion, as happens with the recurrent nevus phenomenon. Confocal reflectance microscopy is an in vivo non-invasive imaging technique with high histomorphological resolution of the skin that can be used to differentiate between benign and malignant lesions, increasing the in vivo diagnostic accuracy. Nonetheless, in some cases only the histological and immunohistochemical examinations of the complete lesion can clarify the diagnosis.

Introduction: In the Brazilian public health system, the current demand for dermatological procedures is greater than the offer, resulting in a waiting list of patients bearing dermatoses to be treated surgically. Aimed at reducing that waiting list, a collective effort of surgical procedures was carried out in the tertiary public health service. The corresponding data on the patients and lesions is disclosed in the present study. Objective: To assess the profile of the patients – and respective skin lesions – who are awaiting to undergo dermatological procedures. Methods: A simple descriptive profile analysis of the patients, treated dermatoses and procedures performed was carried out. Results: Thirty-one patients (aged between 21 and 95 years, mean = 63.7 years). Seventeen (54.83%) were women and 14 (45.17%) were men. Thirty-eight lesions were treated: 21 neoplastic (carcinomas and melanomas), 8 pre-neoplastic (actinic keratoses) and 9 non-neoplastic (nevi, keloid and neurofibroma). Conclusions: The present article is relevant due to the fact it identifies cases and patients awaiting dermatological surgical procedures in the public health system. Based on it, a better planning of public health strategies in the dermatological field should be possible. Also, it highlights the importance of the dermatologist physician’s action in the public health, diagnosing and treating pre-neoplastic and neoplastic lesions.

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 type of neoplasia. Basal cell carcinoma is the most common cancer of them, the incidence of which is steadily increasing, implying an important public and financial health issue. The authors present the case of a patient with an extensive basal cell carcinoma affecting part of the external auditory canal and auricular concha, treated with a combination of surgical techniques: flap-plasty associated with second intention closure of the external auditory canal. Due to the excellent aesthetic and functional outcomes, this technique should be considered as a therapeutic option for auricular lesions.

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.

INTRODUCTION: The gold standard diagnosis of cutaneous melanoma is essentially histological. Dermoscopy adds to clinical examination improved sensitivity and specificity.
OBJECTIVE: To evaluate the histological profile of risk melanocytic lesions excised in a dermatology service.
METHODS: Case review through Excel spreadsheet and survey of dermoscopic, histological and topographic data (January 2017 to December 2018).
RESULTS: Data from 62 suspected melanoma lesions were evaluated in this period. The main histological results were: melanocytic nevi (37.1%), melanoma (19.35%), and dysplastic nevi (17.7%).
CONCLUSIONS: The positive predictive value for melanoma was 19.35%, considering the search for an early diagnosis in patients at risk.

Diagnosing basal cell carcinomas, both clinically and dermoscopically, is part of most dermatologists' daily routine. However, tumors of this lineage, when densely pigmented, can be a challenge for the physician and surgeon. Dermoscopic features typical of melanocytic lesions may be present in these carcinomas, and the similarity with melanoma results in a real dilemma. More in-depth knowledge on this topic can make a difference in the management of these cases.

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.

A Covid-19, doença causadora de síndrome gripal e insuficiência respiratória aguda, vem demonstrando provocar danos a diversos outros órgãos e sistemas. Várias manifestações dermatológicas já foram descritas. Relatamos um quadro de alopecia areata (AA) desencadeada possivelmente pela Covid-19 em paciente que, apesar de ter seu RT-PCR para SARS-CoV-2 negativo, apresentou IgM reagente e sintomatologia clássica relacionada à doença. Acreditamos que a Covid-19 possa ter desencadeado resposta imunológica autoimune, com a consequente produção de interferons, que levou ao quadro de AA.
