Atazanavir-Associated Crystalline Nephropathy.

Crystalline nephropathy can occur following treatment with multiple therapeutic agents. We describe a human immunodeficiency virus (HIV)-infected patient treated for 2 years with combination antiretroviral therapy including atazanavir (ATV). Kidney biopsy revealed a crystalline nephropathy associated with diffuse chronic and granulomatous interstitial inflammation.

A case of mantle cell lymphoma presenting with ascites.

Ascites with the finding of peritoneal carcinomatosis is considered an unusual presentation for mantle cell lymphoma (MCL) and has been rarely described in literature. This case reflects the importance of cytological analysis of peritoneal fluid in a patient with intractable ascites not contributing from other comorbidities. In the event a bone marrow (BM) analysis cannot be made, this may serve as an alternative method for diagnosing MCL taking into consideration the good concordance between peritoneal fluid and BM cytological markers.
