1/2. Naevus anaemicus with teleangiectatic vessels.We describe a 20-year-old man with naevus anaemicus on the chest where, after dermabrasion of the epidermis, enlarged teleangiectatic dark-red vessels were seen within the previously pale area. They were clearly different from those seen on dermabrasion at this site in normal skin and in patients with vitiligo where the area is lighter red with only small punctual bleedings from arterial capillaries. The naevus anaemicus and a port-wine stain (naevus flammeus) in the same location is a phenomenon of vascular twin spotting, which was revealed when the epidermis was removed. The area was transplanted with thin epidermal grafts and healed within 2 weeks. One year later the naevus looked the same as before grafting. Much thicker grafts than those used by us will be needed, but they are not cosmetically acceptable.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/2. Scarring alopecia and sclerodermatous changes of the scalp in a patient with hepatitis c infection.hepatitis c virus (HCV) is a common cause of chronic hepatitis and is frequently associated with extrahepatic disease. Recently, cutaneous disorders have been a presenting manifestation of HCV infection. porphyria cutanea tarda (PCT) is one of the cutaneous diseases associated with hepatitis c. PCT manifests in an acute form with tense bullae and erosions and in a chronic form with milia, scarring, and sclerodermatous changes. HCV has also been implicated as a cause of vasculitis through immune complex deposition. We report a patient in whom HCV was associated with sclerodermoid PCT and a medium vessel vasculitis. This case underscores the importance of HCV and its potential cutaneous manifestations, as well as the importance of recognizing cutaneous manifestations of internal disease that may be the first clue to diagnosis of HCV.- - - - - - - - - - ranking = 0.2keywords = vessel (Clic here for more details about this article) |
