Chondroblastoma: An Unusual Cause Of Shoulder Pain In Adolescence.

Chondroblastoma is a rare benign bone tumor, most often localized in the epiphysis of long bones. We report a case of atraumatic shoulder pain in a 17-year old soccer player. This chondroblastoma case demonstrates the difficult differentiation of chondroblastoma from giant cell tumor and clear cell chondrosarcoma and highlights possible pitfalls and clinical importance.

Case report: relief of acute obstruction of the Detour subcutaneous pyelovesical bypass.

A 36-year-old patient was admitted to the emergency department with complaints of severe flank pain, nausea, vomiting, anuria, and general illness. Five months earlier, we had placed a subcutaneous pyelovesical prosthesis (Detour; Porges) of the ureter for treatment of a chronically dilated upper urinary tract in a solitary right kidney previously treated by double-J stenting. Ultrasonography of the right kidney revealed severe hydronephrosis.
