[Ultrastructural, histochemical and histological study of bladder pheochromocytoma]

In the rarely occuring vesical location the pheochromocytoma shows the usual features as well from morphological (conventional and ultrastructural) as from histochemical point of view. Biochemical examinations confirm the amount of adrenalin and noradrenalin. In connection with this case the authors discuss the problems related to the histogenesis of vesical pheochromocytomas and consider the linking up of this type of tumors to the APUD system.
