Childhood leprosy in Buenos Aires: four cases report.

Childhood leprosy, which affects children up to 14 years old, is characterized by a delay in diagnosis since it is usually confused with other dermatoses. Its presence in a child is a relevant epidemiological indicator since it signals active disease transmission. We present 4 patients between 5 and 14 years old who attended a public hospital in Buenos Aires -two patients with borderline tuberculoid leprosy, one with lepromatous leprosy, and one with indeterminate leprosy.

[Development of porphyria cutanea tarda in a chronic hepatitis C patient with indetectable viremia under treatment with peg-interferon plus ribavirin].

Porphyria cutanea tarda (PCT) is considered an extra-hepatic manifestation of HCV infection. The frequency of this association varies according to different authors and the mechanism by which the virus can trigger this disease is not yet clear. We present a 47-year-old-man with chronic hepatitis C genotype 1b who, during the treatment with peg-interferón alfa 2b plus ribavirina, with no detectable viremia at weeks 12th, 24th, and 48th, developed dermatological photosensitive lesions at week 44th.
