Cutaneous Bowen’s Disease: an Analysis of 182 Cases according To Age, Sex, and Anatomical Site from an Italian Center
Full text linkBowen's disease (BD), also known as squamous cell carcinoma in situ, is a type of non-melanocytic intraepidermal malignancy characterised by a slowly enlarging erythematous to pink, scaly patch or plaque with irregular and well-demarcated borders. These lesions are usually persistent and progressive; it has been estimated that in general population around 3% to 5% of Bowen's disease transform into invasive squamous cell carcinoma. This report describes our experience with cutaneous BD and assesses the differences found about age, sex and anatomical site. Bowen’s disease was seen more frequently in male patients rather than in female patients in contrast to what confirmed in literature - this difference is probably because being head-neck an exposed region, patients are more easily induced to autoexam and to consult the dermatologist
Skin diseases and tattoos: A five-year experience
No full textBACKGROUND:
Decorative tattooing as a body art form underwent an exponential increase during the last two decades, particularly among teenagers and young adults. Consequently, the number of reported adverse reactions after tattooing has increased. The most frequent reported skin reactions to tattoo include infectious (bacterial, viral, fungal) or inflammatory (allergic contact dermatitis and granulomatous reaction) diseases. Moreover, tattoos can also induce the development of typical skin lesions of pre-existing dermatoses, a phenomenon known as isomorphism reactive or Koëbner phenomenon, which commonly occurs in patients with psoriasis, vitiligo, or lichen planus.
METHODS:
A retrospective study analyzing records data of patients attending the Department of Dermatology, University of Naples "Federico II" during 2011-2015 was performed. All cases of tattoo-related or closely-located dermatitis were selected.
RESULTS:
We observed 19 patients (mean age: 26.4 years old) showing cutaneous conditions related to the practice of tattooing. Allergic contact dermatitis was reported as the most common cutaneous disease linked to tattooing (31.6%), followed by granulomatous reactions (26.3%). These data are consistent with those already reported in the literature.
CONCLUSIONS:
Our results highlight the need to develop detailed regulations regarding tattoos practice, used materials, as well as execution procedures in order to limit the outbreak of tattoo-related skin diseases
Instrumental, clinical and subjective evaluation of the efficacy of a cosmetic treatment for home use
No full textBACKGROUND:
In the last few years, there has been increasing demand for aesthetic procedures to improve the effects of skin aging.
AIM:
To evaluate the anti-aging efficacy, tolerability and skin changes induced by the topical products containing hyaluronic acid, N-acetyl glucosamine and gamma-amino butyric acid through instrumental techniques, clinical and subjective evaluation.
PATIENTS/METHOD:
Twenty female enrolled applied a day and night cream after applying a serum, once week applied a mask, for 2 months. A clinical assessment of smoothness, expression wrinkles, fine wrinkles and measurements of the parameters using Reveal Imager, X-Rite, Corneometer, Dermalab, Moisture Meter EpiD were taken at day 0, 15, 30 and 60 of study period. A final assessment questionnaire was submitted.
RESULTS:
The products were accepted by all the volunteers. The hydration (Corneometer: T0 49.17 vs T60 61.11, average variation 24.28%) (Moisture Meter EpiD: T0 45.73 vs T60 61.10, average variation 33.60%), elasticity (Dermalab: T0 56.06 vs T60 62.78, average variation 11.98%) and lightening of the skin (X-Rite: T0 60.23 vs T60 63.36, average variation 5.26%) improved. All changes were statistically significant (p < 0.05).
CONCLUSION:
The efficacy of the topical products is confirmed by subjective, clinical and instrumental assessment. This should be a routine approach in dermatologic practice

Confocal microscopy can assess the efficacy of combined microneedling and skinbooster for striae rubrae
No full textStriae distensae or stretch marks are dermal scars characterized by flattening and atrophy of the epidermis. They develop particularly during adolescence but they can also appear in other situations such as pregnancy, the use of prolonged therapies with topical or systemic corticosteroids, Cushing's syndrome, Marfan's syndrome, prolonged use of lightening creams, cachexia, rapid weight loss or the use of androgenic and anabolic substances. Treatment options often take a long time, and the results are often disappointing, causing significant psychological distress in patients. We propose a completely innovative approach, combining the skinbooster technique with the microneedling technique. These minivasive methods work by inducing tissue remodeling and stimulating the synthesis of new collagen. Confocal microscopy can show and follow the skin changes made by these therapies, thus becoming an important and valid therapeutic monitoring tool for aesthetic dermatology
Management of clinical and subclinical actinic keratoses with histological and immunohistochemical assessments by confocal microscopy
No full textReflectance confocal microscopy has been used to monitor treatment efficacy in non-melanoma skin cancer, but few studies have compared different therapies using the same confocal criteria. We compare a single score designed in previous study to evaluate confocal, histological, and immunohistochemical results obtained before and after two treatments of actinic keratosis (AK) and in field cancerisation area. Thirty volunteer male patients, aged >50-year old, with at least three clinically visible AKs on the bald scalp, were included in this study: 15 patients were submitted to 3% diclofenac therapy and 15 to 5% fluorouracil therapy. Confocal imaging was performed on a 5 × 5 cm skin area. In five patients of each group we performed cutaneous biopsies. Scaling, upper nucleated cells, and inflammatory cells showed a higher percentage reduction in field cancerisation, especially in diclofenac treatment group, while in AK inflammatory cells showed a greater percentage reduction in 5-fluorouracil treatment group. Both therapies are efficacious, but their effectiveness is different on the single parameters of the confocal, histology, immunohistochemically
