Lupus nephritis associated with placental site trophoblastic tumor: A case report and review of the literature

PSTT usually follows a normal pregnancy or an abortion, and can be cured by surgery and chemotherapy (Scully and Young, 1981). The association of PSTT with kidney diseases is very rare. There is a single recorded case of thrombotic microangiopathy (TMA) (Mazzucco et al., 2011) and another of membranous glomerulonephritis (Batra et al., 2007; Bologna et al., 1994). Only 2 other cases of PSTT and kidney lesions have been reported. Both of these were described fully by Young et al. as showing a distinctive glomerular lesion (Young et al., 1985). We describe a case of lupus nephritis (LN) that occurred with PSTT. Kidney biopsy showed diffuse global proliferative LN. This unusual findings must be interpreted appropriately to achieve the correct diagnosis.
