[Jaundice with indirect bilirubinemia via the mother's milk].

Among the clinical entities included in the differential diagnosis of the prolonged jaundice at the end of neonatal period and in the small infant is the jaundice due to mother's milk, whose incidence is of 0.5-2% in the naturally fed infants. The authors present two cases in which the diagnosis was reached by exclusion and confirmed by the therapeutically positive test. Physiopathologic considerations are made on the basis of the literature data, and the nosologic background of the affection is presented. This clinical entity, considered to have an excellent prognosis, presented a special evolution in one of the cases.
