Atypical presentation of a brown tumor in a kidney transplant recipient: a case report.

Brown tumor is a rare complication of secondary hyperparathyroidism. It is exceptionally encountered after kidney transplantation. We here report on a 54-year-old male recipient who developed a brown tumor localized in the right forearm, and whose initial presentation was atypical, mimicking a bone tumor.

Sirolimus for the treatment of Kaposi sarcoma after renal transplantation: a series of 10 cases.

The incidence of Kaposi sarcoma (KS) has substantially increased among immunocompromised patients, suggesting a role for immunosuppressive drugs. The aim of this study was to evaluate the incidence, features, and outcome of KS among 307 kidney transplantation patients at our center between January 1994 and June 2010. During the study period, the 10 patients who developed KS (3.

Early onset of paucisymptomatic cryptococcal meningitis in a kidney transplant patient: a case report and review of the literature.

Fungal infections of the central nervous system are rare and are more frequently encountered in immunocompromised patients. Cryptococcocal infection is the most common opportunistic fungal infection after Candida and Aspergillus in organ transplant recipients. Atypical manifestations and nonspecific neuroradiological findings due to the lack of inflammatory response in these immunocompromised patients are responsible for a delay in diagnosis.

Primary adenocarcinoma in a kidney allograft: a case report and review of the literature.

De novo tumors are common complications after solid organ transplantation. Lymphoma and skin cancers are the most frequently observed malignancies. However, graft carcinomas can be observed to be five times more frequent after kidney transplantation compared to their incidence in the general population.
