Pheochromocytoma: study of 50 cases.

Purpose: We studied the clinical picture, sensitivity of the biochemical tests and imaging studies, pathological findings, surgical results and followup of patients with pheochromocytoma.

Materials And Methods: The records of 50 patients with pheochromocytoma were identified. Hyperadrenergic symptoms and signs; urinary dopamine, epinephrine, norepinephrine and vanillylmandelic acid levels; serum dopamine, epinephrine and norepinephrine levels; ultrasonography; computerized tomography; magnetic resonance imaging and 131iodine-metaiodobenzylguanidine images were analyzed.

[Persistence of Muller's ducts in the male. A family observation (author's transl)].

The authors report two cases (in brothers) of the persistence of Muller's ducts (uterus and uterine tubes), whilst both individuals led a normal though infertile sex life. They presented with a bilateral inguinal hernia and a cryptorchidism. The precise diagnosis was made at surgery in the first, whilst the family history led to the diagnosis in the second.
