Almost all congenital vascular abnormalities affect the skin and are evident from birth or become so during the first few weeks of life. The two most common types of vascular birthmarks, hemangiomas and vascular malformations, may appear to be very similar but their course and treatment are different. Hemangiomas appear in the first few weeks of life and usually regress spontaneously over time....

BACKGROUND Cutaneous vascular proliferations that occur in the field of prior radiotherapy include angiosarcoma and small, cutaneous lesions with a pseudosarcomatous pattern that previously were reported as atypical vascular lesions or benign lymphangiomatous papules. METHODS The objective of this study was to investigate the clinicopathologic features and outcomes of 56 radiation-induced vas...

UNLABELLED Vascular lesions have been classified in two broad categories, hemangiomas and malformations. Encapsulated vascular lesions have not been reported in the oral cavity, but they were described in other sites, mainly in the orbit. Herein, we present a case of an oral encapsulated vascular lesion located in the right buccal mucosa of a 69-year-old male, including histological and immunoh...

Vascular malformations are inborn errors of vascular embryogenesis present at birth that should be diagnosed in childhood and, when necessary, treated to prevent later complications. The current trend is to classify these lesions according to flow characteristics and the predominant type of vascular channel affected. Given the complexity, and in many cases, the rarity, of vascular malformations...

This paper reports the first occurrence of Lasiodiplodia theobromae in Brazil nut (Bertholletia excelsa). Cankers were found on branches 3-year-old plants Belém, Pará, Brazil. The symptomatic displayed reddish vascular lesions. pathogen was identified using morphological and phylogenetic analyses. Koch’s postulates fulfilled, confirming L. nut.

Vascular lesions with telangiectasias on visible areas, such as the face, are common in discoid lupus erythematosus (DLE); however, an efficient management of these skin lesions can sometimes be difficult. Since argon laser light is able to specifically coagulate vascular structures, it has been used in the treatment of various vascular skin malformations. Therefore, we addressed the issue whet...

We studied the effects of anteroventral third ventricle (AV3V) lesions on the vascular Na+-pump activity and blood pressure of rats prepared by the two-kidney Goldblatt procedure. Blood pressures and Na+-pump activity of the isolated tail arteries, measured as ouabain-sensitive 86Rb+-uptake were determined in rats with renal artery clips, rats with AV3V lesions, and rats with AV3V lesions. Rats...
