[Cutaneous manifestations of cytomegalovirus infections].

The cutaneous manifestations that occur commonly in cytomegalovirus (CMV) infections are erythematous maculopapular eruptions or purpuric rashes . But, CMV has been detected in chronic mucosal and skin ulcerations, benign tumour-like lesions and eroded gingivitis. Most of these cutaneous lesions are secondary to vasculitis of the small dermal, subcutaneous tissue or submucosa vessels. The authors discuss the different physiopathological mechanisms which may be involved in the development of these viral-induced vasculitis. Dermal erythropoiesis in neonatal infants and localized granulomatous lesions have been also reported.
