Topical and Intralesional Immunotherapy for the Management of Skin Cancer in Special Locations: Lips and Eyelids.

The use of topical and intralesional immunotherapy in the treatment of cutaneous malignant neoplasia in sensitive areas such as the lips and eyelids is discussed. Surgery may not be feasible or may result in deformities in these areas, making alternative treatment options necessary. A narrative literature review was conducted using MEDLINE (PubMed) as the main literature database, collecting available evidence of experiences with various topical and intralesional therapies in the aforementioned anatomical locations, ranging from case reports to clinical trials. The clearance rates and potential adverse reactions of therapeutic options such as imiquimod 5%, 5-fluorouracil (5-FU), photodynamic therapy (PDT), ingenol mebutate (IM), diclofenac, intralesional methotrexate, and interferon are reviewed. Although limited by their heterogeneity and the scarcity of clinical trials, these studies point towards promising response rates and minimal adverse effects, making these treatments viable options in selected cases.

Use of lip photoprotection in patients suffering from actinic cheilitis.

BACKGROUND: Actinic cheilitis (AC) is a chronic condition that affects mainly the lower lip. OBJECTIVES: To investigate the use of lip photoprotection in patients with AC. MATERIALS AND METHODS: A cross-sectional multicentre study of patients, ≥45 years of age, was performed in eight dermatology departments in the Galicia region over a period of one year. From 1,239 patients included in the study, 410 were diagnosed with AC and complete data were available for 408. An analysis of lip photoprotection habits and possible associations in patients with AC is reported. RESULTS: Mean age of patients with AC was 71.9 years and 53.8% were women. More than 90% of AC patients (370/408) had never used lip photoprotection. In the group of patients who used it, 62.16% of them had only used a single stick within the previous year. The only variable significantly associated with the use of lip sun protection was low Fitzpatrick's skin types I and II (p=0.039). Study limitations include the inclusion of patients 45 years or older and the use of a semiquantitative scale for measuring the frequency of application of lip photoprotection. CONCLUSION: To our knowledge, this is the first European study focused on lip photoprotection in patients suffering from AC. Only a minority of AC patients protect their lips from UV radiation. Specific lip sun protection recommendations should be promoted, especially in high-risk populations.

Actinic Cheilitis Prevalence and Risk Factors: A Cross-sectional, Multicentre Study in a Population Aged 45 Years and Over in North-west Spain.

Actinic cheilitis is thought to be a premalignant lesion or a superficial squamous cell carcinoma. The prevalence of actinic cheilitis in Europe is unknown. The aim of this study was to determine the prevalence of actinic cheilitis in the Galicia region (north-west Spain). Secondary objectives were the description of risk factors of actinic cheilitis. A cross-sectional multicentre study in patients ≥ 45 years of age was performed in 8 dermatology departments in Galicia region during a 1-year period. The prevalence of actinic cheilitis was 31.3%. Significant and independent risk factors of actinic cheilitis after multivariate analysis were age ≥ 60 years, Fitzpatrick skin phototype II, outdoor working for more than 25 years, and previous history of non-melanoma skin cancer. This is the first cross-sectional multicentre study of the prevalence of actinic cheilitis in Europe. Actinic cheilitis was present in almost one-third of the screened patients. Lip examination should be performed in all patients with chronic actinic damage.

Ulcerated dermatofibroma with osteoclast-like giant cells.

BACKGROUND: Ulceration and osteoclast-like giant cells are two pathological features uncommonly seen in dermatofibromas. To our knowledge, the presence of these features has not been previously described within the same lesion. METHODS: We report the clinical, histopathological and immunohistochemical findings of a 38-year-old man with an ulcerated dermatofibroma (DF) on the sole containing OLGC. COMMENTS: DF, or cutaneous fibrous histiocytoma, is a frequent dermatological lesion with many clinicopathological variants. Therefore, a correct diagnosis is not always straightforward, especially when two rare features co-exist in the same lesion. Differential diagnosis was performed with cutaneous and even non-cutaneous lesions. An explanation for the clinicopathological findings is also described.
