Acquired Port-Wine stain: Report of two cases
Acquired port-wine stain is a rare vascular lesion that mimics a congenital port-wine stain clinically and histologically, but is acquired after birth. A survey on more than 60 reported cases in the literature reveals that most of these cases are idiopathic, but some of the cases developed after physical or mechanical trauma, hormonal changes, chronic sun exposure, and medications (OCP, i...
متن کاملA Comparison of Acquired Port-wine Stain with Congenital Port-wine Stain Using an Image Analyzer.
BACKGROUND Recent reports have proposed that there were no differences between acquired port-wine stain (APWS) and congenital port-wine stain (CPWS) except the onset of disease. Pulsed dye laser (PDL) therapy is regarded as the treatment of choice in PWS. Although in some articles, APWS might have shown a better response to PDL than CPWS, this is still controversial. It has been assumed however...
متن کاملIn vivo, high-resolution, three-dimensional imaging of port wine stain microvasculature in human skin.
BACKGROUND AND OBJECTIVES Port-wine stain (PWS) is a congenital, progressive vascular malformation of the dermis. The use of optical coherence tomography (OCT) for the characterization of blood vessels in PWS skin has been demonstrated by several groups. In the past few years, advances in OCT technology have greatly increased imaging speed. Sophisticated numerical algorithms have improved the s...
متن کاملImaging blood flow in human port-wine stain in situ and in real time using optical Doppler tomography.
BACKGROUND Optical Doppler tomography (ODT) combines laser Doppler flowmetry with optical coherence tomography to obtain high-resolution images of blood flow in human skin in situ and in real time. OBSERVATIONS We present a case in which ODT was used on a patient with a port-wine stain (PWS) birthmark to document the change of blood flow in response to laser therapy. It might be possible to u...
