ABSTRACT
BACKGROUND: Squamous cell carcinoma of the lip accounts for 20% of all oral carcinomas. Its diagnosis may be challenging because it clinically resembles actinic cheilitis and inflammatory lesions of the lips. OBJECTIVES: To determine clinical and dermatoscopic predictors of squamous cell carcinoma of the lip vs. other lip lesions. METHODS: Multicentre retrospective morphological study, including histologically confirmed cases of squamous cell carcinoma of the lip and controls consisting of actinic cheilitis and inflammatory lesions of the lips. Clinical and dermatoscopic images were evaluated for the presence of predefined criteria. Crude and adjusted odds ratios and corresponding 95% confidence intervals were calculated by univariate and multivariate logistic regression respectively. RESULTS: A total of 177 lip lesions were evaluated, 107 (60.5%) were squamous cell carcinomas and 70 (39.5%) were controls. The most frequent dermatoscopic criteria of lip squamous cell carcinoma were scales (100%), white halos (87.3%) and ulceration (79.4%). The majority of squamous cell carcinomas displayed polymorphic vessels (60.8%), with linear (68.6%) and hairpin (67.6%) being the most frequent types. Multivariate logistic regression analysis showed that clinical predictors of lip squamous cell carcinoma were exophytic appearance and clinical hyperkeratosis, with 43-fold and 6-fold higher probability respectively. White clods and ulceration in dermoscopy presented a 6-fold and 4-fold increased risk for squamous cell carcinoma respectively. CONCLUSIONS: A scaly lesion with exophytic growth, dermatoscopically displaying white clods, ulceration and linear and hairpin vessels is very likely a squamous cell carcinoma of the lip.

BACKGROUND: A wide variety of both surgical and nonsurgical therapies is currently available for patients with skin cancer. OBJECTIVES: This part of the EPIDERM (European Prevention Initiative for Dermatological Malignancies) project is aimed at the evaluation of the treatment preferences for skin cancer in eight countries of the European Union. METHODS: A multicentre hospital-based case-control study was carried out at dermatology departments in Finland, Germany, Greece, Italy, Malta, Poland, Scotland and Spain. Patients with skin cancer (basal cell carcinoma, actinic keratosis, squamous cell carcinoma, cutaneous malignant melanoma and Bowen disease) were consecutively enrolled between July 2008 and July 2010. Information on the study variables (sex, age, country, tumour type, anatomical location and treatment) was obtained from questionnaires designed by the EPIDERM project. RESULTS: In total, 1708 patients with skin cancer were included. Surgery was the first treatment option in 76·5% of the patients (P = 0·001). Actinic keratosis was the only tumour type in which nonsurgical treatment was more frequent than surgery (91·4%). Tumours on the head were less likely to be surgically excised than those at other locations (odds ratio 0·25, P = 0·001). Simple excision or curettage was the most common surgical procedure (65·4%), followed by graft and flaps (22·4%). Cryotherapy was the most common nonsurgical option (52·4%), followed by imiquimod (18·0%), photodynamic therapy (PDT; 12·0%), 5-fluorouracil (5-FU; 5·7%), and diclofenac with hyaluronic acid (4·0%). CONCLUSIONS: Surgery remains the first-choice treatment of skin cancer. Regarding nonsurgical treatments, the conservative treatments available (imiquimod, 5-FU, PDT and diclofenac gel) have not yet exceeded the use of ablative options such as cryotherapy despite their accepted benefit of treating field cancerization.

BACKGROUND: There are poorly documented variations in the journey a skin cancer patient will follow from diagnosis to treatment in the European Union. OBJECTIVES: To investigate the possible difficulties or obstacles that a person with a skin malignancy in the European Union may have to overcome in order to receive adequate medical screening and care for his/her condition. In addition, we wished to explore differences in European health systems, which may lead to health inequalities and health inequities within Europe. METHODS: Ten European countries took part in this investigation (in alphabetical order): Finland, Germany, Greece, Italy, Malta, Poland, Romania, Spain, the Netherlands and the U.K. The individual participants undertook local and national enquiries within their own country and completed a questionnaire. RESULTS: This exercise has identified important differences in the management of a skin cancer patient, reflecting major disparities in health care between European countries. CONCLUSIONS: Further investigation of health disparities and efforts to address health inequalities should lead to improvements in European health care quality and reduction in morbidity from skin cancer.
