Ingenol mebutate is a macrocyclic diterpene ester, naturally found in the sap of the Australian plant Euphorbia peplus, which proved efficacious for actinic keratosis. In clinical routine, we observed local improvement of MF upon application of ingenol mebutate in MF patients treated for coincidental actinic keratosis within direct proximity of/overlapping with MF skin lesions. Hence, the objective of this study was to assess the effect of topical ingenol mebutate on MF skin lesions. Read More

Photodynamic therapy (PDT) using 10% 5-aminolevulinic acid (ALA) gel (GEL) has been shown to be highly effective for treating actinic keratosis (AK) but has only been studied using red-light activation. The goal of this study was to compare GEL and a 20% ALA solution (SOL) using blue-light activation under typical clinical conditions. This double-blind, split-face study randomized subjects to GEL or SOL application to contiguous 25cm fields containing 4 to 8 AK lesions on either side of the face or scalp (no curettage, 1-hour incubation, no occlusion) followed by blue light exposure (1,000 seconds, 417nm, 10J/cm).

Actinic keratoses (AKs) are common lesions on chronically sun damaged skin, which are morphologically characterized by lower third to full thickness atypia of epidermal keratinocytes. These lesions carry a risk of progression towards invasive squamous cell carcinoma (SCC); therefore, treatment of visible lesions and the field in case of field cancerization is recommended. Treatment of AK includes the destruction of atypical keratinocytes that clinically presents with various degrees of erythema, scaling, crusting, erosion, and other visible and subjective symptoms.

Introduction: Ultraviolet light induced DNA damage, combined with immunosuppression and inflammation are involved in the pathogenesis of actinic keratosis. Photodynamic therapy not only destroys dysplastic cells via tissue destruction and vascular shutdown, but also induces an acute local inflammatory response and activates both the innate and adaptive immune system. In our current work we aimed to compare immunohistochemistry features of inflammatory infiltrate of actinic keratoses after 5-aminolevulinic acid photodynamic therapy with or without Er:YAG laser resurfacing.

Pigmented and irritated types of seborrheic keratosis (SK) can be confused with melanoma, basal cell carcinoma, or pigmented actinic keratosis. Dermoscopic examination may give many clues for the diagnosis of SK, but in equivocal cases the accurate diagnosis can only be made by microscopic features. Herein, we report a striking, isolated pigmented and inflamed SK, located on the waist in an elderly man. Read More

The term keratinocyte skin cancer (KC) stands as an umbrella for different stages within the progression of cutaneous squamous cell carcinoma (cSCC). Its earliest form is named actinic keratosis (AK), while for the in-situ form different synonyms, namely intraepidermal carcinoma (IEC), Bowen's Diseases (BD) and cutaneous squamous cell carcinoma in situ [cSCC(Tis)] or intraepithelial squamous cell carcinoma (iSCC) are used. Instead, cSCC is histopathologically classified into well, moderately and poorly differentiated subtypes. Read More

Basal cell carcinomas are the most common non-melanoma skin cancers. Dermoscopy is an indispensable tool to differentiate superficial basal cell carcinoma from other subtypes and between pigmented and not pigmented ones. Although surgery is considered the gold-standard therapy, new current pharmacological options are available and focus on tumor eradication, increasing cosmetic results and functionality. Read More

In vivo reflectance confocal microscopy (RCM) is a noninvasive high-resolution skin imaging tool that has become an important adjunct to clinical exam, dermoscopy and histopathology assessment, in the diagnosis and management of pigmented macules of the face. The diagnosis of early stage lentigo maligna (LM) and lentigo maligna melanoma (LMM) is challenging and RCM improves the diagnostic accuracy in the differential diagnosis of LM with other macules of the face such as solar lentigo (SL), pigmented actinic keratosis (PAK), seborrheic keratosis (SK) and lichen planus-like keratosis (LPLK). Here we review the state-of-the-art of RCM morphologic descriptors, standardized terminology, and diagnostic algorithms for the RCM assessment of pigmented macules of the face including melanocytic, and nonmelanocytic lesions.

Background: Skin diseases are ranked as the fourth most common cause of human illness, resulting in an enormous non-fatal burden. Despite this, many affected people do not consult a physician. Accordingly, the actual skin disease burden might be even higher since reported prevalence rates are typically based on secondary data that exclude individuals who do not seek medical care.

Background: Conventional photodynamic therapy (PDT) with methylaminolevulinic acid (MAL) and daylight PDT have demonstrated similar efficacy in the treatment of actinic keratosis (AK). The reason for the use of daylight is to reduce pain during illumination but daylight has the limitation of the weather conditions. The difference in the doses of red light applied between these two methods suggests that an intermediate dose with red light conventional illumination could be effective in PDT of AK. Read More

Background: High-risk α-genus human papillomaviruses (α-HPVs) are linked to cervical and genital carcinomas; however, their correlation with cutaneous squamous cell carcinoma (cuSCC) or premalignant skin lesions remains controversial.

Objective: We evaluated the contribution of high-risk α-HPV to the occurrence of cuSCC, Bowen's disease and actinic keratosis (AK), and the distribution of high-risk α-HPV genotypes in these cutaneous tumours.

Methods: HPV genotypes were determined using a commercial PCR-based microarray on skin tissue samples collected from 76 [38 young (<60 years) and 38 elderly (>60 years)] cuSCC, 34 Bowen's disease, 48 AK patients and 10 young controls. Read More

DEAR EDITOR, many findings support the role of β human papillomaviruses (HPVs) in cutaneous squamous cell carcinoma (cSCC) and its precursor Actinic Keratosis (AK), in cooperation with UV radiation [1]. Differently from the mucosal high-risk types, which are required throughout the entire carcinogenic process, β-HPVs appear to play a role only at an early stage of skin carcinogenesis. Indeed, β-HPV DNA is not present in all cancer cells and cutaneous HPV prevalence and/or viral load is higher in AK than in cSCC [2, 3, 4]. Read More
