We have previously reported a unique disorder in two brothers with multi-system neuronal degeneration, hepatosplenomegaly and adrenocortical deficiency. The clinical features were different from Refsum's disease. Biochemical analysis suggested that a metabolic defect of the omega 6 polyenoic fatty acid pathway may be involved. In the present study, were have further identified by gas chromatography-mass spectrometry two branched-chain fatty acids, phytanate and pristanate, in these two patients' plasma. This small, but unequivocally elevated elevated amount of branched-chain fatty acids were primarily localized in the triacylglycerols of plasma low density lipoprotein. Such branched-chain fatty acids were not detected in skin, liver and sural nerve samples. These two cases may represent an alternative metabolic error to that found in Refsum's disease leading to phytanate accumulation.

Combined application of clinical, genetic and histological criteria in general allows a definite diagnosis of autosomal dominant ichthyosis vulgaris and of X-linked recessive ichthyosis. For differential diagnosis, the following rare syndromes should be considered: ichthyosis bullosa: Refsum syndrome; Jung-Vogel syndrome; ichthyosis with corneal opacity, pili torti and alopecia; ichthyosis with deafness, pili torti and dental anomalies; and ichthyosis with hepatosplenomegaly and cerebellar degeneration.

Peroxisomes or microbodies are peculiar subcellular organelles with an important role in the metabolism of a variety of different organic compounds. Particularly they are an important site of bile acids synthesis. Some hepatic diseases, mainly cholestatic, can to be reconnected at disorders of bile acids synthesis by these organelles. From the biochemical point some diseases present alterations of the cholesterol side chain (Zellweger syndrome, pseudo-Zellweger syndrome, infantile Refsum's disease, neonatal adrenoleukodystrophy), other diseases present errors involving the steroid nucleus (familial giant cell hepatitis). Zellweger disease or cerebro-hepato-renal syndrome is characterized clinically by skeletal changes, muscle hypotonia, renal cysts, psychosomatic retardation and persistent cholestasis and from the ultrastructural standpoint by the virtual absence of liver cell peroxisomes. Pseudo-Zellweger disease shows many of the clinical features of Zellweger disease but differs from this condition on account of the presence of abundant peroxisomes in the liver cells. Infantile Refsum's disease and neonatal adrenoleukodystrophy show typical clinical disorders and liver damage leading to cirrhosis. "Familial giant cell hepatitis" is characterized by jaundice from the first days of life, hepatosplenomegaly, cholestasis, lack of physical malformations. The disorder is due to defective biosynthesis of the bile acids with formation of allo-bile acids.
