Tricho-hepato-enteric syndrome: further delineation of a distinct syndrome with neonatal hemochromatosis phenotype, intractable diarrhea, and hair anomalies.

We report on two sibs with syndromal congenital iron storage disease. Prenatal symptoms were IUGR, hydramnios, and placental hyperplasia. Clinical anomalies included hypertelorism and sparse, thin, curly hair (trichomalacia). Clinical course was marked by intractable diarrhoea, with normal histological and enzymological studies, cholestatic jaundice, hepatomegaly appearing after 30 days, and progressive liver failure, leading to death after a few months. The only metabolic anomaly was progressive hypermethioninemia. Pathologic examination of both children showed a similar pattern of multivisceral iron deposit compatible with a diagnosis of neonatal hemochromatosis: extensive liver fibrosis or cirrhosis with nodular regeneration, cholestasis, ductular proliferation, and hepatic, pituitary, thyroidal, adrenal, and pancreatic iron deposition. The unusual course for neonatal hemochromatosis in both sibs combined with concordant extrahepatic anomalies suggest that they could have a specific iron storage syndrome with possible autosomal recessive inheritance, probably similar to the sibship reported by Stanckler et al. [Arch Dis Child, 57:212-216, 1982].
