[Childhood leprosy: Report of a case].

Childhood leprosy is very common, especially in tropical and subtropical areas, such as Paraguay. Early symptoms can be missed in a routine examination and the diagnosis can pass unnoticed. Pediatricians and dermatologists should remember the manifestations of this disease in order to make an early diagnosis.

[Prurigo nodularis].

Prurigos are a heterogeneous group of disorders of questionable or unknown etiology characterized by subjective symptoms such as accentuated itching and an eruption of chronic or recurrent papulonodules as an objective sign. They are divided into acute and chronic; acute forms being the most frequent in childhood. We present the case of a child with nodularis prurigo, a variety of chronic prurigo, with symmetrically affected axilary regions.
