Parvovirus B19 is the cause of a variety of exanthematous diseases during childhood and adolescence, such as erythema infectiosum and papular purpuric gloves and socks syndrome. This is an unusual, benign and acute acrodermatitis. Aphtous stomatitis, fever and other systemic symptoms can be associated with the eruption of the purpuric rash. Uncommon patterns such as asymmetrical distribution or erythematous involvement llave recently been described as additional features of PVB19-associated purpuric petechial eruption. This is a case report of a 12-year-old female with an atypical involvement of a papular-purpuric syndrome caused by human parvovirus B19.

Resumen El parvovirus B19 es causante de una variedad de enfermedades exantemáticas durante la infancia y adolescencia, como el eritema infeccioso y el síndrome papular purpúrico en guante y calcetín. Este último es una acrodermatitis aguda, inusual y benigna, que puede asociarse a aftas orales, fiebre y otros síntomas constitucionales. Existen casos atípicos como la púrpura febril en otras localizaciones, sin cumplir la distribución característica en guante y calcetín de forma simétrica o con un mayor componente de eritrodermia. Presentamos el caso de una adolescente de 12 años con un síndrome papular purpúrico de distribución atípica por parvovirus B19.

Infection with Strongyloides stercoralis is a common parasitic infection in tropical and subtropical regions, including the Peruvian Amazon. The clinical manifestations are varied in patients with immunocompromised disease, and the systemic spread of the disease is frequent, compromising different organs and systems. Cutaneous manifestations are infrequent, being described in patients with some degree of immunosuppression. We present the case of an immunocompetent patient who developed a reactive purpura due to chronic Strongyloides stercoralis infection. Thus, skin involvement is possible in immunocompetent patients with systemic exacerbation due to this parasite.

A 59-year-old atopic man referred to for the onset of a diffused itching papular-purpuric eruption involving his trunk and legs but without systemic symptoms. History revealed that he started feeling itching after spending few hours in his basement. Direct examination of the environmental dust (www.edpa.it) showed high level of infestation of Solenopsis fugax, a small Myrmicinae ant. The skin eruption completely healed without scarring in 2 weeks. Specific disinfestation measures were performed and the patient did not comply of any recurrence during a 6-months follow-up.
