Objectives: The objective of the study was to analyze the demographic profile, histopathological features, risk factors, and recurrence rates in patients with basal cell carcinoma. Materials and Methods: A retrospective study was conducted from 2012 to October 2018 in 29 patients with histopathologically confirmed basal cell carcinoma. All the patients had undergone either excision or cryotherapy as per the institution protocol. Information on the history of the disease, occupation, history of sun exposure and clinical and histopathological features were collected and analyzed. Results: A female preponderance was found (n = 18, 62.1%), majority of the patients were unemployed (44.8%), 19 patients (65.5%) gave a history of sun exposure, and the nose was the most common site of disease. Ten females (34.5%) did not have any excessive exposure to the sun, but gave a history of exposure to heat and fumes in the kitchen. Six patients (20.7%) had a preexisting nevus at the same site and superficial spreading type was the most common histopathological type (n = 24, 82.8%). Excision gave the best result. Four patients (13.8%) had recurrence of the disease. Limitations: Small sample size was the major limitation. The risk factors and occupation could not be analyzed objectively. Conclusion: This is a pioneer study from Kerala. A female preponderance (62.1%) was observed. The role of heat, fumes, type of oven, and use of reheated oil in cooking as risk factors for the development of BCC needs analysis in future studies. Superficial spreading type was the most common pattern observed in histopathology slides (82.8%). Excision gives near-complete clearance and a good cosmetic result with less risk of recurrence.

Ultraviolent (UV) solar radiation is considered to be the dominant risk factor for development of basal cell carcinoma (BCC). The development of BCC is thought to arise from intense, intermittent sun exposure leading to burns. Identifying patients with high-risk factors for developing BCC includes chronic immunosuppression, exposure to ionizing radiation, and certain genetic syndromes. Primary treatment goals of BCC include cure of tumor with maximal preservation of function. Although rarely metastatic, BCC can produce substantial local destruction. Treatment modalities can be divided into surgical and nonsurgical therapies, although surgical therapy is the mainstay of treatment. Superficial therapies, such as topical imiquimod or 5-fluorouracil, photodynamic therapy, or cryotherapy, may be effective for anatomically challenging locations where surgery or radiation is contraindicated, but the cure rates of these approaches are lower compared with surgery. Recent FDA-approved hedgehog pathway inhibitors include vismodegib and sonidegib for patients who have exhausted surgical and radiation options for treating advanced BCC.

AbstractBasal cell carcinoma (BCC) represents the most commonly diagnosed human cancer among persons of European ancestry with etiology mainly attributed to sun-exposure. In this study we investigated mutations in coding and flanking regions of the PTCH1 and TP53 genes and noncoding alterations in the TERT and DPH3 promoters in 191 BCC tumors. In addition, we measured CpG methylation within the TERT hypermethylated oncological region (THOR) and transcriptions levels of the reverse transcriptase subunit. We observed mutations in PTCH1 in 59% and TP53 in 31% of the tumors. Noncoding mutations in TERT and DPH3 promoters were detected in 59% and 38% of the tumors, respectively. We observed a statistically significant co-occurrence of mutations at the four investigated loci. While PTCH1 mutations tended to associate with decreased patient age at diagnosis; TP53 mutations were associated with light skin color and increased number of nevi; TERT and DPH3 promoter with history of cutaneous neoplasms in BCC patients. TERT promoter mutations but not THOR methylation associated with an increased expression of the reverse transcriptase subunit. Our study signifies, in addition to the protein altering mutations in the PTCH1 and TP53 genes, the importance of noncoding mutations in BCC, particularly functional alterations in the TERT promoter.

AbstractThe aim of the present case-control study was to assess the risk factors for Basal cell carcinoma (BCC) in the Montenegrin population. The study group was comprised of 100 consecutive patients with a diagnosis of BCC, while the control group consisted of patients who did not present skin cancer and who were individually matched to the cases by sex and age. The increased risk for BCC was associated with: the presence of nevi (odds ratio [OR] = 3.77; 95% confidence interval [CI] = 1.12–12.73), type of skin concerning to burn rather than to tan after repeated sun exposure in childhood or adolescence (OR = 3.14; 95% CI = 1.59–6.18), the skin reaction to burn after two or more hours of sunlight during childhood or adolescence (OR = 4.53; 95% CI = 2.37–8.63), the number of severe and painful sunburns during their lifetime(OR = 3.52; 95% CI = 1.68–7.38), outdoor work during the summer-time (OR = 2.73; 95% CI = 1.00–7.45), occupational exposure to chemicals (OR = 17.89; 95% CI = 2.82–113.52), history of eczema (OR = 4.17; 95% CI = 1.53–11.39), and history of previous BCC (OR = 3.86; 95% CI = 1.40–10.65). Our study confirms the role of environmental and constitutional factors in development of BCC.

BACKGROUND Public awareness for BCC is particularly important, as its major risk factors — increased sun exposure and number of sunburns — are largely preventable. OBJECTIVE Determine whether social media posts from celebrities has an affect on public awareness of basal cell carcinoma. METHODS We used Google Trends to investigate whether public awareness for basal cell carcinoma (BCC) increased following social media posts from Hugh Jackman. To forecast the expected search interest for BCC, melanoma and sunscreen in the event that each celebrity had not posted on social media, we used the autoregressive integrated moving average (ARIMA) algorithm. RESULTS We found that social media posts from Hugh Jackman, a well-known actor, increased relative search interest above the expected search interest calculated using an ARIMA forecasting model. CONCLUSIONS Our results also suggest that increasing awareness by Skin Cancer Awareness Month may be less effective for BCC, but a celebrity spokesperson has the potential to increase awareness. BCC is largely preventable, so increasing awareness could lead to a decrease in incidence.

Although malignant melanoma (MM) and both basal cell carcinoma (BCC) and actinic keratosis (AK) are sun-induced lesions, the coexistence of these entities at the same anatomical site (collision tumour) is exceedingly rare. We report the case of a 54-year-old woman with a known history of xeroderma pigmentosum variant (XPV) who presented with 2 separate skin lesions over the middle and upper right forearm, respectively. The clinical impression was that of BCCs or squamous cell lesions. On histological examination, both specimens showed features of melanoma <em>in situ </em>(MIS). In the first lesion, MIS merged with and colonised a superficial and focally invasive BCC. In the second lesion, MIS merged with an AK. No separate invasive nests of malignant melanoma were seen in either specimen. The atypical melanocytes were highlighted by Melan-A and HMB-45 immunostaining, whereas the epithelial cells in both the BCC and AK stained with the pancytokeratin MNF-116. The patient had a previous history of multiple MMs and non-melanomatous skin cancers and finally developed widespread metastatic malignant melanoma, which proved fatal. The rare and interesting phenomenon of collision tumours may pose diagnostic difficulties. To our knowledge, this is the first reported simultaneous presentation of cytologically malignant collision tumours in a patient with XPV.

Abstract The aim of this study was to analyze the dermoscopic features in patients with pathohistologically confirmed basal cell carcinoma (BCC). Our retrospective study included 54 patients with 76 BCCs in total, diagnosed in 2016 and 2017. All lesions were classified into four clinical types: nodular, pigmented, superficial and infiltrative. Digital dermoscopic images were evaluated by three observers. We selected five dermoscopic features for analysis, including: the absence of pigment network, the presence of arborizing vessels, blue-gray globules and ovoid nests, leaf-like areas and ulcerations. In the total of 54 patients, there were 22 females and 32 males. At the moment of establishing the diagnosis, the patients’ age was in the range from 31 to 84 years (median age 67 years). The most frequent clinical type was the nodular type with 28 confirmed diagnoses. Nodular BCC was more frequently localized on the head and neck areas compared to the trunk and limbs (p < 0.01). Dermoscopically, the absence of pigmented network was verified in all cases. Arborizing vessels were present in 71 (93.4%) lesions, blue-gray globules and ovoid nests in 33 (42.1%), ulcerations in 44 (57.9%), and leaf-like areas in 5 (6.6%) lesions. Blue-gray globules and ovoid nests were significantly frequent in pigmented BCC in comparison to other clinical types of BCC (p < 0.01). In conclusion, using dermoscopy, it is entirely possible to make a reliable diagnosis of BCC as well as to differentiate it from others skin tumors.
