[Childhood eosinophilic pustulosis].

Childhood eosinophilic pustulosis is a rare disease that is characterized by recurrent outbreaks of pruritic pustules and follicular papules. The lesions are sterile and contain masses of eosinophils related to the scalp hair follicle. Because of the good prognosis for these symptoms, conservative treatment with topical corticosteroids is recommended.

Maspin expression in normal skin and usual cutaneous carcinomas.

Maspin is a serine protease inhibitor whose gene is located on 3q27. Several lines of evidence point towards its putative role as tumor suppressor gene and angiogenesis inhibitor; however, there are compelling data showing that maspin is also expressed in the nuclear compartment and might be associated with the differentiation of specific cell lineages. No systematic study of maspin expression in normal skin and usual skin carcinomas have been published so far.

p63 expression in normal skin and usual cutaneous carcinomas.

Background: p63 is a p53 homologue that is mapped to chromosome 3q27. This gene encodes six different isoforms, which have either transactivating or dominant negative effects on p53-reporter genes. It has been described that in contrast to p53, p63 seems not to be associated with tumor predisposition, as neither p63 knockout mouse models nor germline p63 mutations are related to an increased risk of tumorigenesis.
