title: [2 cases of sympathetic paraganglioma of the urinary bladder].
abstract: Two cases of symphathetic paraganglioma of the urinary bladder are reported. Symppathetic- or parasymphatetic origin of intramural paraganlia or paragangliomas can be determined by demonstration of praesynaptic myelinated fibers. This method gives more reliable results than formaldehyd-induction-method carried out on freezed sections or the Gömöri's chromaffin reaction which often appears to be false-negative.
