Recognition of adrenal atrophy during a review of autopsy findings in two sisters who died at 8 months and 3 1/2 years prompted estimation of very long chain fatty acids, phytanic acid and pristanic acid on wet liver fixed in formalin for 12 years. These were shown to be markedly increased and defects in multiple peroxisomal functions and decrease in(More)
Two 6-year-old patients with clinical signs of leukodystrophy had no nosological diagnoses in vivo. Neuropathological studies revealed scavenger cells to be clustered in perivascular regions of the demyelinated brains. Histochemical and ultrastructural details of the non-metachromatic storage macrophages suggested lipid storage and prompted a biochemical(More)
Very long chain fatty acids (VLCFA) were found to be markedly increased and phytanic acid was borderline above normal in formalin-fixed brain white matter of case with an unusual type of familial leukodystrophy with epitheloid cells as described previously by Gullotta et al. [Neuropädiatrie (1970) 2: 173-186]. Increased VLCFA in brain clearly demonstrate(More)
An 18-month-old infant presented with a history of arrest of neurological development from the age of eight months, with progressive ataxia, deafness, retinitis pigmentosa and hepatomegaly. Biochemical investigations revealed an elevated plasma phytanic acid level and deficiency of phytanic acid oxidase in skin fibroblasts. Histopathological findings in a(More)
Tables 2 and 5 summarize the major clinical and biochemical findings in these patients. Cases 1 and 2 resemble clinically the previous cases of children reported as suffering from infantile phytanic acid storage disease, Zellweger's disease, or neonatal adrenoleucodystrophy. Cases 3 and 4 differ strikingly from these and from one another. Numerous questions(More)
