Transepidermal elimination (TE) is a mechanism whereby foreign or altered constituents can be removed from the dermis. This process involves unique morphologic alterations of the epidermis, which forms a channel and thereby facilitates extrusion of the desired dermal components. The phenomenon of TE may occur as a primary process characterizing disorders, such as elastosis perforans serpiginosa...

We report a novel technique that fuses 3D digital subtraction angiograms and MR images. Image fusion was successfully performed within 20 minutes each in 11 consecutive cases. Our initial experience showed that this image fusion enabled clear and simultaneous visualization of perforating arteries and surrounding tissues. The relation between perforating arteries and normal brain or lesions was ...

BACKGROUND Cantharidin is a topical vesicant that causes intraepidermal acantholysis with clinical application that includes the removal of warts, molluscum contagiosum (MC), calluses, and acquired perforating dermatoses. OBJECTIVE To provide a comprehensive literature review of the efficacy and safety of cantharidin in the management of various cutaneous conditions. METHODS A PubMed search...

The results of the examination and surgical treatment of 132 patients with CEAP class C2-C6 varicose disease of the lower extremities have been analyzed. A combined diagnostic method that allows detecting the peculiarities of the functioning of the perforating vein venous system of the shin, namely, allows establishing the uncompetency of the perforating veins of the shin objectively, has been ...

The objective of this study was to introduce a method for repairing large soft-tissue defects on the foot. Distally based neuro-fasciocutaneous flaps with perforating vessels were designed along the saphenous and sural neurovascular axes. The cutaneous perforating branches of the major arteries of the lower extremities were used as pedicles, which provided a rotation arc for the cross-leg flap ...

Recent epidemiological evidence suggests that there are two forms of Crohn disease (CD): perforating and nonperforating. We hypothesized that, just as with tuberculoid and lepromatous leprosy, differences in the two forms of CD would be both identified and determined by differences in the host immune response. Resected intestinal tissue from control patients as well as perforating and nonperfor...

Breast reconstruction after breast-conservation surgery is an important issue for breast cancer patients. Various factors are associated with complications, of which blood flow is one of the more important. The perforating branches of the internal thoracic artery (ITA) are key contributors to blood flow in the anterior chest wall. The present study examined the distributions and depths of the p...

There is an unusual vascular network at the base of the brain in patients with moyamoya disease. We detected various histologic lesions in the perforating arteries of 22 patients. Vessels showing rupture ranged from 50 to 530 microns in diameter; they were dilated, some had fibrin deposits in the wall, fragmented elastic laminae and attenuated media. Non-ruptured perforating arteries (diameter ...

OBJECTIVES To assess the technique of subfascial endoscopic ligation of incompetent perforatory veins by use of a mediastinoscope. DESIGN Prospective open clinic study. SETTING Two Departments of Surgery. MATERIALS AND METHODS Thirty-eight consecutive patients (40 legs) with recurrent or protracted venous ulceration of the lower leg were treated. Through a short, transverse incision of th...
