          Abstract

          Laser Doppler flowmetry (LDF) is frequently used to study the microcirculation. Usually LDF time series are analyzed by conventional linear methods, mainly Fourier analysis. The aim of this study was to observe dynamic blood perfusion of the skin in malignant and benign melanocytic skin lesions. Wavelet transformation was performed on each LDF time series in order to calculate a vasomotion field. First, the differences in vasomotion between healthy and pigmented skin were evaluated visually on six different time scales of the vasomotion field. In order to quantify the findings, vasomotion scale variance (VSV) was calculated for each scale plane of the vasomotion field. These VSV were compared using contrast ΔVSV to determine the difference between healthy skin and a pigmented skin lesion in the same patient. After the measurements, the skin lesions were excised and examined histologically. We found that wavelet analysis of LDF time series is a specific, sensitive method for the in vivo identification of malignant melanoma. It is a non-invasive procedure and takes minimal time to be carried out.

              A sensitivity and specificity analysis of the surface microscopy features of invasive melanoma.

              S W Menzies, C Ingvar, W H McCarthy (1996)
              In vivo cutaneous surface microscopy, epiluminescence microscopy, dermoscopy, dermatoscopy and magnified oil immersion diascopy, are terms that describe the use of an incident light magnification system to examine cutaneous lesions, usually with immersion oil at the skin-microscope interface. The result is the visualization of a multitude of morphological features, not visible with the naked eye, that enhance the clinical diagnosis of nearly all pigmented lesions. Sixty-two invasive melanomas and 159 randomly selected non-melanoma pigmented lesions were used in the study. The non-melanomas, while randomly selected from a large data base, were all clinically atypical. Using the x 10 magnification of hand-held surface microscopes (Dermatoscope, Episcope), we present an analysis of 72 surface microscopic variables (constituting over 15,000 single observations) for the diagnosis of invasive melanoma. Forty of the 72 features studied were shown to differ significantly between invasive melanoma and non-melanoma pigmented lesions. Blue-white veil, multiple brown dots, radial streaming and pseudopods had a specificity greater than 95% for melanoma. Two features, symmetrically irregular pigment (non-uniform pigmentation with point and axial symmetry) and the presence of a single colour, had a sensitivity of 0%, i.e. were absent, in melanoma. The other significant features are presented, with their sensitivity and specificity for melanoma.
