Introduction: Primary parvovirus B19 infection may present a wide variety of dermatological features. We report two cases of parvovirus infection presenting as flexural erythema of baboon syndrome induced by various drugs, but associated with purpuric or oedematous features., Case Reports: A pregnant 23-year-old woman at 39 weeks of amenorrhoea and a 49-year-old woman consulted for flexural eruption in a setting of fever. In both cases, clinical examination revealed erythematosus rash in the major skin folds, with vesicles and elements of purpura in the former patient and bullous oedema in the latter. In both cases, the diagnosis of primary parvovirus B19 infection was confirmed by positive PCR screening of viral genome and by seroconversion after two weeks. The skin lesions regressed spontaneously within several days., Discussion: Although initially linked solely with systemic drug toxicity, baboon syndrome has since been reported in connection with other allergens (drug reactions, contact dermatitis, viral and streptococcal infection). Among these causes, parvovirus B19 infection merits particular interest., (Copyright © 2010 Elsevier Masson SAS. All rights reserved.)

Introduction: Parvovirus B19 infection is frequent. Primary infection leads to diverse skin manifestations including the recently described gloves-and-socks papulopurpura., Case Report: A patient presented with a papulopurpuric eruption on the nose, hands, feet and perineum with cheilitis and high-grade fever. Parvovirus B19 serology showed characteristic IgG on the 15th day after the initial eruption demonstrating the seroconversion. Cold agglutinins were positive during the eruption and negative after regression., Discussion: The gloves-and-socks papulopurpura syndrome was initially described in 1990. Since that time 20 cases have been reported. In 7 cases, primary parvovirus B19 infection was proven and viral infections were suspected in the others (measles, coxsackie B6, hepatitis B, Epstein-Barr virus). Our case evidenced here to undescribed skin manifestations and the development of cold agglutinins. The presence of cold agglutinins at eruption could explain the acral localizations observed in this syndrome.
