Sixteen skin tumours and one BCG vaccination granuloma were examined by 20-MHz B-scan ultrasound. Images were compared with closely matched histological sections of excised lesions. The correlation between histology and ultrasound was excellent for maximum tumour depth measurements (r = 0.96, P < 0.0001), but less good for maximum width (r = 0.84, P <(More)
Ultrasound is widely used in general clinical medicine for non-invasive internal imaging. Over the last twenty years, technological advances have enabled the application of high-resolution ultrasonic imaging to the skin. Equipment and hardware is now available to produce cross-section images and three-dimensional reconstructions of selected skin segments.(More)
The feasibility of targeted screening for cutaneous malignant melanoma in the UK using a postal questionnaire and invitation to screening by a consultant dermatologist was investigated in a population based cross-sectional survey. A total of 1600 people aged 25-69 years, stratified by the social deprivation score of wards within one general practice, were(More)
Non-invasive skin imaging techniques have proliferated over the last decade. Whilst most have a research role, some are routinely used in dermatology clinics. Of these, the skin surface microscope (dermatoscope), a diagnostic aid for pigmented lesions, has had most clinical impact. Such devices, when linked to a videomicroscope for computer analysis, have(More)
BACKGROUND In the South-west Thames region there were an unprecedented number of lichenoid tattoo reactions to red ink in patients who had visited a local tattoo parlour. The red ink was found to contain mercuric sulphide, a compound known to cause allergic reactions. Topical Dermovate (clobetasol propionate 0.05%, GlaxoWellcome) ointment alone had little(More)
OBJECTIVES To study the feasibility of developing targeted screening for those at high risk of melanoma by examining how attitudes relate to (a) acceptance of an invitation for a free skin check and (b) self assessed and clinically assessed risk factors for developing cutaneous melanoma. DESIGN A population based cross sectional survey. SETTING A(More)
BACKGROUND There are potential clinical benefits if non-invasive methods can be used to diagnose or exclude melanoma. OBJECTIVES We investigated high-resolution ultrasound (HRU) as a potential non-invasive diagnostic aid for pigmented skin lesions. METHODS Using a 20-MHz ultrasound B-scan imaging system interfaced to a computer, we assessed acoustic(More)
Cosmetic causes of scarring alopecia are poorly documented. They include traction alopecia and hot-combing. Recently, another group has presented in the South London area, related to misuse of chemical hair straightening agents. Affected patients are young, female, of Afro-Caribbean origin, and typically display hair loss on the vertex of the scalp.(More)
