Is there any relationship between massive ascites and elevated CA-125 in Systemic Lupus Erythematosus? Case report and review of the literature.

Systemic lupus erythematosus (SLE) is a chronic, multisystemic autoimmune disease of variable presentation. Massive ascites in the context of SLE is infrequent. Even so, it has been reported that ascites may be the first manifestation of SLE. It is difficult to diagnose due to the multiple possible etiological causes of ascites. There is a rare entity called Pseudo-Pseudo Meigs Syndrome (PPMS) in patients with SLE who have ascites, pleural effusion, and CA-125 elevation unrelated to malignancy. We present two cases of massive ascites, pleural effusion, and elevation of CA-125 with a history of SLE diagnosis. One of these cases was diagnosed with PPMS and another associated with neoplasm of ovarian origin.
