(en) [Diabetes mellitus as the initial manifestation of pheochromocytoma: Report of two clinical cases] In rare cases, diabetes mellitus is actually secondary to another endocrinopathy. We report the clinical cases of two middle-aged, non-obese patients who developed non-insulin-dependent diabetes. Abdominal imaging led to the incidental discovery of a pheochromocytoma. These adrenal tumors usually manifest themselves by headaches, palpitations, sweating, and hypertension. Yet catecholamine hormones may also impact glucose metabolism due to their actions on pancreatic a- and p-adrenergic receptors. Surgical resection usually leads to diabetes remission. These clinical reports highlight the requirement for a full etiological investigation in alypical diabetes cases,
