Membranous glomerulonephritis (MGN) is known to cause post-transplant nephrotic syndrome and may be recurrent or de novo [1,2]. Focal glomerulosclerosis (FGS) may also present with nephrotic range proteinuria and has a high incidence of recurrence post-transplantation (2040%) and approximately half of these recurrences may lead to allograft failure. The risk of recurrent MGN has been reported to be 29% at 3 years and it appears to be more common than de novo MGN in transplant recipients [2, 3]. Schwartz et al. [2] have reported that de novo MGN may occur in 5.3% of patients at 8 years. Although nephrotic syndrome is known to complicate underlying malignancies in the non-transplant setting, the association between nephrotic range proteinuria and tumours following renal transplantation is less well defined. This case report addresses the possible mechanisms of proteinuria in a patient with simultaneous recurrent
