[Finnish-type nephrotic syndrome: report of the fourth case in Italy and review of the literature].

The Authors have studied anamnestic, clinical and morphological data of a case of Congenital Nephrotic Syndrome of Finnish type (CNS-FT). Similarly to the first case reported in Italy, the patient was born by consanguineous parents. For the determination of the real incidence of this disease, in countries shere CNS-FT is rarely signalled, the importance of histopathological examination of the kidney is emphasized.
