The Wood’s light assisted the physician in locating the site of a completely regressed primary cutaneous melanoma, determining the clinical borders of a lentigo maligna melanoma, differentiating between agminated naevi and a naevus spilus and detecting the recurrence of pigmentation after the excision of a dysplastic naevus, and also proved useful in monitoring a large segmental speckled atypical lentiginous naevus for change. Despite the availability of many‘high-tech’imaging and diagnostic devices designed to evaluate skin lesions, the relatively simple Wood’s lamp continues to be of great value. We encourage physicians not to abandon the use of the Wood’s light in their clinical practice.展开更多

In areas of high incidence this will place a significant burden on the health system. Objectives: To establish the awareness, knowledge and attitudes of the general public to NMSC and provide an overview on their level of understanding and knowledge of preventative measures. Methods: Two thousand and one hundred Caucasian and Hispanicindividuals,aged 40-75 years,fromthe UK, Italy, Germany, Spain, France, the USA and Australia were randomly selected to participate in this market research survey. In a structured telephone interview lasting approximately 10 min, respondents answered questions on NMSC, specifically actinic keratosis (AK) and basal cell carcinoma (BCC). Results: Overall, 6%of respondents had been diagnosed with NMSC, of which the incidence was highest in Australia and the USA.The frequency of skin cancer detection examinations was also greater within these populations. Countries with a high incidence of NSMC had greater awareness of the condition, with more awareness of BCC than AK. The majority of respondents believed there was a correlation between skin cancer and sun exposure, however, a minority of respondents associated skin cancer with ‘moderate’tanning. Overall, 86%of respondents claimed that they always took precautions against ultraviolet exposure when in the sun, but only 26%applied sunscreen most or all of the time when they were exposed to the sun for more than 1 h. In most of the countries, outside workers reported lower sunscreen use than other respondents. Conclusion: Nonmelanoma skin cancer awareness and prevention behaviors varied significantly among the countries studied. Improved population-specific documentation of skin cancer knowledge and prevention behaviors will facilitate the development and assessment of public health campaigns.展开更多

We now report 4 more cases, confirming that the initial case was not an isolated finding. We examined the lesions clinically, with a dermoscope, with a Wood’s light, and in 3 cases with UV photography so as to exclude nevus spilus from the differential diagnosis. The presence of an underlying dysplastic nevus syndrome phenotype in 4 of the 5 cases raises the possibility that agminated nevi arise as a consequence of postzygotic loss of heterozygosity and, thus, may represent a type 2 segmental manifestation of the atypical mole syndrome phenotype. Further studies of similar cases using microdissection techniques for analysis of loss of heterozygosity pattern are warranted.展开更多
