A 54-year-old woman was diagnosed as having polycystic kidney in 1990. Renal transplantation was performed in 1995. She received immunosuppressive therapy postoperatively. Skin lesion was recognized on the left leg in April 2002 and skin biopsy demonstrated diffuse large B cell lymphoma in March 2006. EBV-LMP, EBNA-2 and EBER were positive and she was diagnosed as having EBV-related posttransplant lymphoproliferative disease (PTLD). Radiation therapy and rituximab therapy were administered. The skin ulcer worsened and she was referred to our hospital. We reduced the dose of immunosuppressive drug and performed debridement of the ulcer, which responded well to treatment. PTLD presenting with skin involvement rarely manifests as lesions, and such lesions develop slowly, when they occur. PTLD presenting with skin involvement after transplantation must be treated.

Apoptosis in the cystic epithelium is observed in most rodent models of polycystic kidney disease (PKD) and in human autosomal dominant PKD (ADPKD). Apoptosis inhibition decreases cyst growth, whereas induction of apoptosis in the kidney of Bcl-2 deficient mice increases proliferation of the tubular epithelium and subsequent cyst formation. However, alternative evidence indicates that both induction of apoptosis as well as increased overall rates of apoptosis are associated with decreased cyst growth. Autophagic flux is suppressed in cell, zebra fish and mouse models of PKD and suppressed autophagy is known to be associated with increased apoptosis. There may be a link between apoptosis and autophagy in PKD. The mammalian target of rapamycin (mTOR), B-cell lymphoma 2 (Bcl-2) and caspase pathways that are known to be dysregulated in PKD, are also known to regulate both autophagy and apoptosis. Induction of autophagy in cell and zebrafish models of PKD results in suppression of apoptosis and reduced cyst growth supporting the hypothesis autophagy induction may have a therapeutic role in decreasing cyst growth, perhaps by decreasing apoptosis and proliferation in PKD. Future research is needed to evaluate the effects of direct autophagy inducers on apoptosis in rodent PKD models, as well as the cause and effect relationship between autophagy, apoptosis and cyst growth in PKD.
