title: Rare Presentation of a Rare Disease (Erdheim-Chester disease): A Case Report.
abstract: Erdheim-Chester disease (ECD) was first reported by J. Erdheim and W. Chester, in 1930. There are less than 250 reported cases till date. We report a case of ECD in a 16- year-old Malay male, who initially presented with elusive anemic symptoms with more specific symptoms of bony pain, cardiorespiratory and hepatic involvement evolving as the disease progressed.
