Primary and Isolated Renal Hydatid Cyst in Systemic Lupus Erythematosus - Abstract
The primary renal localization of the hydatid cyst (HC) is exceptional and unusual. It is one of the so-called “aberrant” or “ectopic” localizations of human echinococcosis with an overall prevalence estimated at 1.5-5% but is exceptionally isolated and primitive. The association of echinococcosis with Systemic Lupus Erythematosus (SLE) remains exceptional and suggests a hypothetical causal link. We report the original observation of a primary and isolated renal HC diagnosed in a 59-year-old Tunisian woman followed for SLE. Our observation is, to our knowledge, the fourth to report this association. It is characterized by its exceptional location (kidney) and its isolated and primitive character. Thus a screening for hydatidosis seems to be beneficial for subjects monitored for lupus disease in the endemic areas of this parasitosis.
