This report describes a case of a female with systemic lupus erythemat
osus, who was subsequently diagnosed with Fabry's disease. Due to simi
larities in the organs involved by these two multisystem disorders, di
fficulties were encountered in establishing a prompt diagnosis of Fabr
y's disease. That and subsequent management of this patient are discus
sed. A literature review of the coexistence of the two disorders along
with the potential pathogenic mechanisms explaining this association
are explored.
