Background Recent evidence suggests that melanoma is a family of different tumours with varying abilities to grow and metastasize. Trends in melanoma epidemiology show a strong increase in the incidence of thin melanoma, with no corresponding increase in mortality or incidence of thick melanoma. We initially evaluated five cases and found that none had baseline features suggestive of melanoma; excision was performed based on slight changes visible only in side‐by‐side comparisons of dermoscopic images. Objectives To assess the clinico‐dermoscopic features and the growth patterns of melanomas that were excised after a follow‐up of 1 year or more due to their inconspicuous features at the baseline consultation. Methods In a multicentre, retrospective study of histopathologically confirmed melanomas excised after follow‐up, we analysed dermoscopic images obtained at the initial consultation and compared them with images obtained at the last follow‐up consultation. Images were analysed and graded using standard algorithms and scored for changes in size, symmetrical or asymmetrical structural change, and development of new melanoma‐specific criteria. An overall score reflecting the amount of change was calculated for each lesion. Results Our series consisted of 103 melanomas. After a median follow‐up of 20 months, most lesions were still in situ or early invasive (median Breslow thickness of 0·48 mm), with only three lesions showing tumour thickness of 1 mm or more. The most frequent baseline characteristics were asymmetrical pigmentation (78·6% of lesions), reticular overall pattern (62·1%), and regression features (35·9%). Most melanomas (58·3%) showed minor to moderate changes over time, with < 2 mm size increase, with asymmetrical structural change, and without development of new melanoma‐specific criteria. Major changes were visible only after a mean follow‐up of 33 months. Conclusions This study provides evidence for the existence of a subgroup of slow‐growing melanomas, which may explain the increase in the incidence of thin melanoma, despite stable rates of thick melanoma and melanoma‐associated mortality.
Acne is defined as a chronic inflammatory disease of the pilosebaceous units, mainly affecting the face of young adults, but the chest and back can be involved as well. Oral antibiotics, topical retinoids, azelaic acid, benzoyl peroxide, and isotretinoin represent the most common treatment used for the treatment of acne, but several adverse effects and a lack of durable remission, with poor adherence by the patients, have been reported thus far. Lasers have been shown to be effective and safe to treat acne; intense pulsed light (IPL) demonstrates high efficacy rates, minimal discomfort, rapid recovery times, and excellent cosmetic and therapeutic outcomes.In this prospective study, we assessed the efficacy, safety, and reproducibility of a novel IPL protocol as a monotherapy in the treatment of acne of the chest and back.We included patients (N=50) aged 14 to 30 who presented with moderate papulopustular acne sited on the chest and back (Cook's Acne Grading Scale method 4-6, Pillsbury Scale III-IV). We performed four IPL sessions at two-week intervals on each patient.An excellent outcome was achieved in 50 percent of the patients and a good outcome in the 35 percent of the patients. Patients experienced light erythema and mild burning as the most common side effects, which spontaneously resolved within 24 to 96 hours.Consistent with previous reports, our study demonstrated IPL to be a safe and effective treatment for severe cases of acne on the chest and back, providing excellent aesthetic and therapeutic results in 85 percent of treated patients.
To create a dermoscopic classification of atypical melanocytic nevi (Clark nevi) and to investigate whether individuals bear a predominant type.
Design
Digital dermoscopic images of Clark nevi were classified according to structural features, ie, reticular, globular, or homogeneous patterns or combinations of these types. The nevi were also characterized as central hypopigmented or hyperpigmented, eccentric peripheral hypopigmented or hyperpigmented, or multifocal hypopigmented or hyperpigmented.
Setting
Two pigmented skin lesion clinics.
Patients
We examined 829 Clark nevi on 23 individuals.
Main Outcome Measure
A reliable dermoscopic classification of Clark nevi and frequency of different dermoscopic types.
Results
Using the dermoscopic classification, the 829 Clark nevi were classified as follows: 221 (26.7%) as reticular, 167 (20.1%) as reticular-homogeneous, 148 (17.9%) as globular-homogeneous, 112 (13.5%) as reticular-globular, 89 (10.7%) as homogeneous, 84 (10.1%) as globular, and 8 (1.0%) as unclassified. Most individuals were prone to a predominant type of Clark nevus. Seven individuals (30%) showed a single type of Clark nevus in more than 50% of their nevi and 5 (22%) in more than 40% of their nevi.
Conclusions
The proposed dermoscopic classification of Clark nevi is easily applicable and allows a detailed characterization of the different dermoscopic types of Clark nevi. Knowledge of these dermoscopic types should reduce unnecessary surgery for benign melanocytic lesions. Exact classification of the different types of Clark nevi is a necessary prerequisite for further clinical, dermoscopic, and histopathologic studies, which will give new insights in the biology of acquired melanocytic nevi.
Background: Teledermoscopy uses telecommunication technologies to transfer images of pigmented skin lesions, including clinical and anamnestic data, via email to specialized centers for teleconsultation.Design: Sixty-six pigmented skin lesions examined on a face-to-face basis in a skin lesion clinic in L'Aquila, Italy, were sent via e-mail on a standard-resolution color monitor for consultation at a university dermatology department in Graz, Austria.Intervention: Digital photographs of the clinical and dermoscopic images of all pigmented tumors were taken with a stereomicroscope connected to a high-resolution video camera in Truevision advanced graphic array (Targa) format file and converted successively into a Joint Photographic Expert Group (JPEG) format file.All lesions were excised surgically and diagnosed histopathologically.Main Outcome Measure: Diagnostic concordance between face-to-face diagnosis and telediagnosis.Results: The diagnostic concordance was 60 (91%) of 66 cases.The number of correct telediagnoses was lower, but the difference was not statistically significant (Wilcoxon test, P = .10).The accuracy of the telediagnoses was not related to the quality of the images, but highly depended on the level of diagnostic difficulty of a given pigmented skin tumor (Spearman correlation, P = .01). Conclusion:Teleconsultation of clinical and dermoscopic images of skin tumors via e-mail provides a similar degree of diagnostic accuracy as face-to-face diagnosis.
The interactive Atlas of Dermoscopy is a multimedia project for medical education based on a CD-ROM with over 2,000 images of pigmented skin lesions. In addition, an internet connection for continuing medical education and up-to-date services is provided. The Interactive Atlas is composed of a course section including various self-assessment tests. Using a large database, users can evaluate their ability to recognise dermoscopic criteria, to diagnose pigmented lesions and to calculate diagnostic algorithms. This interactive course will guide you through a rapid, multi-step and easy learning phase covering basic and advanced aspects of dermoscopy.
As the sequence of events of impaired wound healing is well characterized, the possibility to identify treatments that are already in the market and that are known to target one or, even better, many of the described molecular events can be taken into account.In this regard, several molecules with different indications have shown beneficial effects in promoting wound healing.Through these molecules, a most recent and effective one is represented by Rigenase ® , a peculiar patented triticum vulgare extract which in association with polyhexanide, an antiseptic that doesn't give any resistance to bacteria, characterizes the Fitostimoline ® Plus formulations.Rigenase ® , consists of a mix of oligosaccharides, having consolidated activities in the wound healing process.Polyhexanide is an antiseptic that has specific activities on bacteria, fungi and some viruses.The Fitostimoline ® Plus formulations are present in the form of gauzes, spray and cream and all represent a valid and safe alternative for the treatment of various type of wounds, including burns, abrasions, ulcers and lesions.In this trial, we evaluated through a survey on a large population of patients, the efficacy and tolerability of the Fitostimoline® Plus formulations considering which one is the eligible product for each specific indication, in order to help the physicians to choose among the various types of these medical devices.
Androgenetic alopecia (AGA) with its precursor miniaturization of anagen phase (MA) and telogen effluvium (TE) represent nonscarring hair loss diseases which causes moderate to severe aesthetic and psychologic discomfort in affected people. Several therapeutic approaches have been tested through the latest decades, with different degree of success. In this study we aim to analyze the efficacy and outcome of an innovative therapeutic protocol, named TRICHOBIOLIGHT, a combination of active principles conveyed by mesotherapy directly on the scalp with a subsequent photobiostimulation session with LED light (630 nm). About 107 patients (49 women, 58 men, mean age 45-year-old) with clinical and trichoscopic diagnosis of MA, AGA, and TE have been enrolled at Skin Center of L'Aquila, Avezzano and Pescara (Italy) and subsequently treated with the TRICHOBIOLIGHT protocol. 4 patients dropped out at the beginning of the study: 2 patients because of an histological diagnosis of scarring alopecia and lichen scleroatrophicus, and 2 patients dropped out because of adverse reaction to the treatment. Excellent to good outcome have been reached in the 82.5% of patients (85/103), 9 patients (8.7%) reached a sufficient result while 7 patients (6.8%) partially respond to the treatment. Two patients (2%) did not respond at all. TRICHOBIOLIGHT is a promising protocol, working through the combined action of the active principles and the photobiostimulation, that lead to a strengthening and thickening of the residual hair, giving an optical thickening effect that provides high quality aesthetic results and, consequently, appreciable psychological results.
