1/6. Intravascular spread of keratoacanthoma. An alarming but benign phenomenon.We report a patient with a keratoacanthoma of the scalp in which there was invasion of several medium-sized vessels by the tumour at a distance from the main lesion. A marked inflammatory response within the invaded vessels as well as a benign clinical course do not suggest that this phenomenon represents malignant transformation.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/6. An unusual presentation of giant cell arteritis.A 77-year-old-man with giant cell arteritis who developed bitemporal scalp ulcerations is described. Since 1946 when Cooke et al. reported the first case of scalp necrosis there were approximately 55 cases published. scalp ulceration is a rare complication of giant cell arteritis and occurs mainly in elderly persons, particularly women. About half of all patients were presented to dermatologists. Most of the patients (70%) had other serious complications of giant cell arteritis: blindness, gangrene of the tongue and nasal septum necrosis. Seventy percent of the cases were confirmed by a temporal artery biopsy. The necrosis were of varying extent and uni- or bilateral. Although, in most cases necrosis has been located bilaterally as in the presented case. scalp healing was complete nearly in all patients by conservative treatment within a year. scalp ulceration is a potentially reversible complication of giant cell arteritis which indicates extensive vessel involvement and adequate coricosteroid therapy is required and essential.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
3/6. Aplasia cutis congenita of the scalp: how much therapy is necessary in large defects?AIM: To show that local antibiotic management and a regular inspection of aplasia cutis congenita of the skull can give an excellent result. METHOD: This case reports a girl born with aplasia cutis congenita of the skull presenting with a large aplasia of the epidermis, dermis, subcutaneous tissue and galea, including a bone defect without any additional risk factor, e.g. early eschar formation, cerebrospinal fluid leakage or uncommon dural blood vessels. RESULTS: A primarily conservative treatment with local wet and antibiotic dressings together with a systemic antibiotic treatment for the first 2 wk led to an excellent result and thus prevented untimely operative and peri-operative procedures. CONCLUSIONS: Here we have shown that conservative treatment might be an option, even if the wound diameter is greater than 1 cm(2), to prevent infants from any untimely operative procedure with an elevated operative risk if any additional risk factors are excluded.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
4/6. Acute ocular hypotony. A rare complication of temporal arteritis.Acute ocular hypotony is a serious, but rare complication of temporal arteritis. It occurs equally often in men and women, and appears mostly in patients older than 70 years. This complication may occur in one or in both eyes. In the literature 7 cases of temporal arteritis accompanied by ocular hypotony have been reported. Hypotony probably results from a restricted production of aqueous humor caused by involvement of the arteries supplying the ciliary body. A high-dose corticoid therapy may normalize completely the intraocular pressure, and a timely treatment may preserve a satisfactory vision, since an insufficient perfusion of the optic disc does not necessarily occur. scalp necrosis and diplopia may appear at the same time, and are a sign of multiple involvement of the arterial vessels.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
5/6. scalp necrosis in temporal (giant cell) arteritis:implications for the dermatologic surgeon.Temporal arteritis, a variant of giant cell arteritis, is a systemic granulomatous vasculitis of large and medium-sized arteries. Usually the clinical features are dominated by ophthalmological and neurological complications. In rare instances, ischaemic necrosis, especially of the scalp, may lead patients to the dermatologist. We report a 76-year-old woman presenting with a unilateral scalp necrosis, accompanied by a dramatic ipsilateral impairment of vision. Immediately after duplex-sonography of the extracranial vessels and after initiation of corticosteroid therapy, the diagnosis of temporal arteritis was confirmed by temporal artery biopsy. One month later, because of insufficient secondary healing of the ulcer, the defect was covered by a mesh graft. The taking of the graft was delayed due to immunosuppressive therapy, but was complete. The patient unfortunately died as a result of complications related to surgical removal of an aspergilloma in the sphenoid cavity secondary to immunosuppressive therapy. We discuss the technique of artery biopsy and the possibility of surgical management of scalp necrosis in temporal arteritis.- - - - - - - - - - ranking = 0.5keywords = vessel (Clic here for more details about this article) |
6/6. 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 = 0.5keywords = vessel (Clic here for more details about this article) |
