Abstract
Cutis marmorata telangiectatica congenita (CMTC) is a very rarely occurring congenital disorder with persistent cutis marmorata, telangiectasia, and phlebectasia. This disorder may be associated with cutaneous atrophy and ulceration of the involved skin. We herewith report a 20-year-old female patient with CMTC since childhood along with ulcerations on both breasts. CMTC is a benign vascular anomaly presenting with dilatation of capillaries and veins of dermis and is apparent at birth. The patient had reticulated bluish-purple skin changes over both breasts. Although it resembled physiological cutis marmorata, it was more pronounced and definitely was unvarying and permanent in pattern. A variety of vascular malformations have been described along with this disorder. Etiology is not very clear; it may be multifactorial in origin. Prognosis in uncomplicated cases is good.
Highlights
A dermoscope allowing the use of surgical light as illumination
Our dermoscope is a modularly structured dermoscope composed of three parts: (1) a video or still digital camera with high-power zoom ability used for monitoring and recording images of the skin lesion; (2) a macro conversion lens used to enable macrophotography; and (3) a selfmade transparent spacer used to allow external light to pass through and to keep a precise distance between the tip of the macro conversion lens and the skin surface (Figure 1)
Dermoscopic examination is performed with a gel applied to the skin surface under surgical light illumination from an oblique direction (Figure 2)
Summary
A dermoscope allowing the use of surgical light as illumination In dermoscopic examination, lighting of high quality and high intensity is needed to obtain accurate color reproducibility and correct microstructural identification of the target skin lesion. Ordinary built-in illumination systems may be not sufficient to fulfill the requirement. We designed a dermoscope that allows the use of surgical light as illumination.
