[Epidural malpositioning of an interscalene plexus catheter].

A patient received an interscalene plexus catheter before shoulder surgery. After induction of general anesthesia catheter placement was performed with Winnie's technique and 5 ml of ropivacaine was injected via the catheter. In the recovery room slight dyspnea without wheezing was observed which improved spontaneously.

Giant cystic pheochromocytoma located in the renal hilus.

A malignant tumor in the past medical history of a patient often makes the differential diagnosis of a second tumor more difficult, especially if one of the tumors does not show its characteristic features. The authors report a case of a 55-year-old male who presented with a malignant melanoma on his left shoulder. A retroperitoneal giant cystic mass, 200 mm in diameter, was found incidentally.
