Adrenomyeloneuropathy is a rare X-linked inherited disorder of peroxisomes characterized by the accumulation of very long chain fatty acids (VLCFA) in the central and peripheral nervous system, adrenal glands and testis leading to the dysfunction of these organs and systems. The phenotypic expression is highly variable, childhood cerebral adrenoleukodystrophy and adrenomyeloneuropathy being the main variants. Here we report a case of adrenomyeloneuropathy presenting initially as Addison's disease, which remained undiagnosed for many years with many rare features. We could not locate any other publication on this subject in the indexed journals of literature published from India.
