Background Epstein-Barr virus (EBV)-associated post-transplant lymphoproliferative disease (PTLD) is predominantly of B cell origin. The concept of clonal evolution from poly- to monoclonal lymphoproliferation has been put forward, but T-cell PTLDs are rare with an unknown etiology. ⋯ Interestingly, both manifestations exhibited identical monoclonal peaks in the T-cell receptor rearrangement polymerase chain reaction (PCR) analyses. Conclusion These findings suggest the existence of clonal evolution in EBV-associated T-cell PTLD, leading to the proposal of the novel concept of polymorphic T-cell PTLD.

We report the case of a 42-year-old man with bronchiectasis who had a history of infertility treatment for obstructive azoospermia. Young's syndrome was suspected based on the triad of obstructive azoospermia, sinusitis, and bronchiectasis. He had normal electron microscopy findings, normal nasal nitric oxide levels (116 nL/min), and no situs inversus. ⋯ This led to a diagnosis of primary ciliary dyskinesia (PCD). Distinguishing PCD from Young's syndrome in patients with the triad of obstructive azoospermia, sinusitis, and bronchiectasis is challenging. Young's syndrome may be a phenotype of PCD.

Rectal prolapse is typically treated surgically, and internal therapy has not been reported. We encountered a case of rectal prolapse that improved with an over-the-scope clip (OTSC) system. ⋯ The OTSC system was used to close the rectal perforation and subsequently improved her rectal prolapse, probably because the rectal wall was anchored to the retroperitoneum. This is the first report to show that rectal prolapse can be endoscopically improved and that an OTSC system might be a viable alternative method for managing inoperable rectal prolapse.
