ABSTRACT
Urticarial vasculitis is a rare clinicopathologic entity characterized by urticarial lesions that persist for more than 24 hours and histologic features of leukocytoclastic vasculitis. Patients can be divided into normocomplementemic or hypocomplementemic. The authors report the case of a healthy 49-year-old woman with a 1-year history of highly pruritic generalized cutaneous lesions and finger clubbing. Laboratory tests together with histopathologic examination allowed the diagnosis of hypocomplementemic urticarial vasculitis, chronic hepatitis C and type II mixed cryoglobulinemia. The patient started symptomatic treatment and was referred to a gastroenterologist for management of the hepatitis C, with progressive improvement of the skin condition. The development of hypocomplementemic urticarial vasculitis in the context of chronic hepatitis C is exceedingly rare and possible pathogenic mechanisms are discussed.
RESUMO
A vasculite urticariforme é uma entidade clinico-patológica rara caracterizada por lesões urticariformes com duração superior a 24 horas e uma vasculite leucocitoclásica na histologia. É dividida em normo e hipocomplementêmica. Os autores relatam o caso de uma mulher saudável de 49 anos, com lesões cutâneas intensamente pruriginosas e baqueteamento digital com 1 ano de evolução. O estudo efectuado permitiu efectuar os diagnósticos de vasculite urticariforme hipocomplementêmica, hepatite C crônica e crioglobulinêmia mista tipo II. A doente iniciou tratamento sintomático e foi referenciada para a Gastroenterologia para orientação da hepatite, com melhoria progressiva das lesões cutâneas. O desenvolvimento de vasculite urticariforme hipocomplementêmica no contexto de hepatite C crónica é raro e os possíveis mecanismos patogênicos são discutidos.
