Introduction. Basal cell carcinoma of the skin is the most common skin cancer in people with fair skin color. Early detection of basal cell carcinoma and proper surgical approach are crucial to reduce the incidence of this tumor. Visual examination is the first screening tool used by clinicians, but sometimes it is not enough to differentiate and determine treatment tactics. Therefore, non-invasive methods such as dermatoscopy and ultrasonography of the skin have recently become widely used, which provide a clear diagnosis, fully correlate with the pathomorphological diagnosis and allow determining the invasiveness of the process and the scope of surgery. The aim of the study. To establish the effectiveness of the diagnosis of basal cell carcinoma of the skin using dermatoscopy in combination with ultrasound, to clarify and justify the feasibility of using a double diagnostic test "Dermatoscopy + Ultrasound" in the diagnosis of skin tumors for future surgery. Materials and methods. Two cases of basal cell basal cell carcinoma in young patients with atypical localization, dermatoscopic and ultrasonographic parameters, correlation with pathomorphological diagnosis are described. Dermatoscopic parameters were evaluated according to G. Kittler's algorithm, skin ultrasound was performed on an expert class device "ACUSON Juniper Ultrasound System" with color and energy Doppler modes by a linear multifrequency transducer (5-17MHz) according to the original protocol developed by G.Alakhverdian. Results. A feature of the described clinical cases is the young age of patients (21 and 29 years), which is an atypical phenomenon in relation to the manifestations of BCC and indicates that recently basal cell carcinoma begins to occur at a young age and its typical location changes. The obtained data of dermatoscopic and ultrasonographic examination confirm specific clinical symptoms and are completely correlated with pathomorphological diagnosis. Conclusions. Dermatoscopy in combination with skin ultrasonography are reliable non-invasive techniques that allow real-time detection of clinical and subclinical lesions and should be used to diagnose and monitor for all skin cancers. Keywords: basal cell carcinoma of the skin, dermatoscopy, ultrasonography of the skin.

Basal cell carcinoma (BCC) is the most common skin cancer, and solar ultraviolet ray exposure is the most significant risk factor for its development. The plantar foot is infrequently exposed to the sun, thus the presence of BCC on the sole is rare. We report a case of BCC on the sole of the foot and its treatment in the hope to facilitate its detection.

Cytological Features

Background: Basal cell carcinoma (BCC) is the most common skin cancer in the white population. Nonsurgical treatments are first-line alternatives in superficial BCC (sBCC); therefore, differentiating between sBCC and non-sBCC is of major relevance for the clinician. Scraping cytology possesses several advantages, such as an earlier diagnosis and scarring absence, in comparison to a biopsy. Nevertheless, previous studies reported difficulties in differentiating the different BCC subtypes. The objective of this study was to determine the capability and accuracy of scraping cytology to differentiate between sBCC and non-sBCC. Methods: In this retrospective study, cytological samples of histologically confirmed BCC were examined. Select cytological features were correlated to BCC subtypes (sBCC or non-sBCC). Results: A total of 84 BCC samples were included (29 sBCC; 55 non-sBCC). An inverse correlation between the diagnosis of sBCC and the presence of mucin, dehiscence, and grade of atypia in the basal cells was observed. The presence of medium and large basal cell clusters correlated directly to a sBCC diagnosis. The presence of clear cells is strongly associated with sBCC. Therefore, Conclusion: Scraping cytology is reliable in differentiating sBCC from other BCC subtypes.

BACKGROUND: Basal cell carcinoma is the most common form of cancer in humans. OBJECTIVES: To identify the epidemiology of basal cell carcinoma in Taubaté-SP and verify a possible association between topography and the different histological subtypes of this tumor. METHODS: This was a cross-sectional study conducted at The University Hospital of Taubaté between 01/01/08 and 12/31/09. The study included patients with a confirmed diagnosis of basal cell carcinoma, of both genders, without age restrictions. The variables studied were incidence of basal cell carcinoma, topography, histological subtype, skin color, age and gender. We employed the chi-square test to identify the association between histological subtype and topography, and the student's t test to compare the mean age of onset for the different histological subtypes. RESULTS: The study included 239 individuals. The mean age of the sample was 68.0 years. Male subjects (57.7%) and whites (87.1%) predominated in the study. The predominant histological subtype was nodular (34.7%), followed by the superficial subtype. The most frequent sites of involvement were the head and neck (areas exposed to light), with predominance of the nasal region. The superficial subtype was an exception, as it showed a strong association with unexposed areas like the trunk. The mean age of onset of superficial basal cell carcinoma also differed from that of the other histological subtypes, 63.0 and 69.0 years, respectively. CONCLUSION: The results of this study suggest an association of the superficial histological subtype with younger patients and unexposed areas of the body, linking this type of tumor with a pattern of intermittent sun exposure, more similar to the standard photocarcinogenesis of melanoma.

BACKGROUND The performance of deep-learning image recognition models is below par when applied to images with Fitzpatrick classification skin types 4 and 5. OBJECTIVE The objective of this research was to assess whether image recognition models perform differently when differentiating between dermatological diseases in individuals with darker skin color (Fitzpatrick skin types 4 and 5) than when differentiating between the same dermatological diseases in Caucasians (Fitzpatrick skin types 1, 2, and 3) when both models are trained on the same number of images. METHODS Two image recognition models were trained, validated, and tested. The goal of each model was to differentiate between melanoma and basal cell carcinoma. Open-source images of melanoma and basal cell carcinoma were acquired from the Hellenic Dermatological Atlas, the Dermatology Atlas, the Interactive Dermatology Atlas, and DermNet NZ. RESULTS The image recognition models trained and validated on images with light skin color had higher sensitivity, specificity, positive predictive value, negative predictive value, and F1 score than the image recognition models trained and validated on images of skin of color for differentiation between melanoma and basal cell carcinoma. CONCLUSIONS A higher number of images of dermatological diseases in individuals with darker skin color than images of dermatological diseases in individuals with light skin color would need to be gathered for artificial intelligence models to perform equally well.

Basal cell carcinoma is the most common skin cancer, with a very low incidence of metastases, associated with high morbidity and mortality. The morpheaform clinical variant is uncommon, presenting an aggressive growth pattern. Early diagnosis and new targeted therapies for metastatic disease are important to improve survival rates. We present the case of a 29-year-old patient with morpheaform basal cell carcinoma in the right genian region. Due to local recurrences, he underwent surgery and adjuvant radiotherapy. For extensive metastatic bone involvement, the patient started vismodegib and, later, pembrolizumab, and also performed palliative radiotherapy. Despite several lines of systemic therapy, the disease progressed, and the patient died after 8 years of follow-up. This case shows how crucial it is to identify risk factors for metastatic basal cell carcinoma and highlights the need to improve target therapies and tailor them to the patient’s biological profile.

White Adults

Basal cell carcinomas are common skin tumors occurring in white adults that are mainly attributable to ultraviolet-B exposure.1 They grow slowly, invade locally, and rarely metastasize.2 Basal cell carcinomas appear most frequently on the head, neck, and upper extremities. The majority occur on the face and the relative risk for recurrent tumor is high in certain sites, especially the nose.3 It is uncommon to see actinically induced basal cell carcinomas in children. There are well documented associations of basal cell carcinomas in children with the nevoid basal cell carcinoma syndrome, xeroderma pigmentosum, nevus sebaceus of Jadassohn, preceding exposure to x-irradiation, or preceding scar from a burn or trauma.4-10
