title: Ectopic Cushing's syndrome due to a pheochromocytoma: a new case in the post-partum and review of literature.
abstract: Cushing's syndrome due to AdrenoCorticoTropic Hormone (ACTH)-secreting pheochromocytoma has been rarely reported during pregnancy and post-partum. We report the case of a 30-year-old woman who presented 3 months after delivery acute psychiatric signs and rapid progressive features of Cushing's syndrome. Hormonal tests confirmed ACTH-dependant Cushing's syndrome. A computed tomography scan revealed a 25 x 30 mm tumoral mass in the left adrenal gland and octreoscan scintigraphy showed only an uptake of the radiolabelled octreotide by the adrenal tumor. Fractionated 24-h urinary catecholamines and metanephrines were in the normal range, except for slightly increased adrenalin levels. A left laparoscopic adrenalectomy was performed with acute pulmonary oedema following the anesthesia. Histological examination revealed a 3.5 x 2.5 cm adrenal tumor consistent with a pheochromocytoma without signs of malignancy. The tumor cells immunostained for ACTH and diffuse hyperplasia of adrenocortical cells was observed. After surgery and short stay in intensive care unit, clinical and biological signs rapidly improved and both anti-hypertensive treatment and insulin injections were withdrawn. Genetic testing did not reveal germline mutations in RET protooncogene, Von Hippel Lindau and succinate deshydrogenase genes.
