[Pheochromocytoma and autoimmune hypothyroidism]

The association of multiple endocrine diseases is frequent and the coincidental involvement of the thyroid and adrenal glands is well recognized. On the contrary, two cases of hypo or hyperthyroidism have only been reported in literature: one concerning adrenal pheochromocytoma with simultaneous autoimmune hypothyroidism and another of a diffuse toxic goiter associated with pheochromocytoma. The purpose of the present report is to point out a new case of a pheochromocytoma associated with an autoimmune hypothyroidism in which the latter is florid and not biochemical.
