No full textTwo sporadic cases of idiopathic multiple minute digitate hyperkeratosis
No full textMultiple minute digitate hyperkeratosis (MMDH) is a skin disease of unknown aetiology characterized clinically by multiple minute asymptomatic keratotic lesions with spiky horny projections. The disorder has been classified into early (congenital) and late (acquired) onset forms, the latter occurring as a presenting sign of concomitant inflammatory, metabolic or malignant disease. Here we report two cases of late onset MMDH without any associated patholoyg. These cases emphasize that some cases of late-onset MMDH may be idiopathic
Non melanoma skin cancer and photoageing in farmers professionally exposed to ultraviolet radiations
No full textSkin photoaging in farmers professionally exposed to ultraviolet radiations
No full textBackground: Most personal exposures to UV radiations occur from outdoor activities and several studies detected a significant association between skin cancer and outdoor occupation. Objective: The aim of the study was to ascertain the prevalence of photoaging signs in a population of Italian farmers and in a population of indoor workers taking account of confounding factors.Methods: 169 farmers and 198 indoor workers were classified for skin phototype and for skin photoaging, moreover 13 variables were taken into account. Marginal permutation tests were adopted for statistical analysis. Results: Farmers were significantly older than the indoor workers. In workers occupationally exposed to UV photoaging increased with increasing age and years of occupational exposure to sunlight. The distribution of skin phototype did not show significant differences in the two populations, while farmers showed a higher degree of photoaging than indoor workers. Conclusions: Even if farmers were older than the indoor workers it seems that outdoor work produces a higher degree of photoaging
The use of non-invasive diagnostic techniques for the advanced diagnosis of skin cancer among agricultural workers
No full textA new surgical approach for the treatment of severe epithelial skin sun-induced damage
No full textBackground. Cutaneous photoageing is a complex biological process affecting all layers of the skin. Skin damage resulting from intrinsic ageing and extrinsic photoageing may trigger skin cancer. In patients with advanced photoageing and/or diffuse actinic damage, local therapy is often inadequate and the possibility of combined therapy needs to be assessed. Subjects. Here we report three cases of patients over 75 years of age with advanced diffuse epithelial skin damage of photoexposed areas consisting of several superficial actinic keratoses, ipermelanotic lesions and multiple skin cancers. Methods. Neoplastic lesions and damaged skin were removed by superficial erbium laser ablation and the epidermis reconstructed with autologous epidermal sheets expanded in vitro from healthy cells obtained from unexposed areas of the body. Results. Our initial studies show that this procedure is very effective in the short term for treating and preventing the UV-induced skin cancer and precancerous lesions, and also suggest good long-term control of the disease with very interesting aesthetic results
