We present a 54-yr-old woman with ectopic corticotropin syndrome caused by a neuroendocrine tumor of the pancreas. At initial presentation, the patient suffered from diarrhea, heartburn, and nonspecific abdominal pain. There was no evidence of Cushing's syndrome. A neuroendocrine tumor in the head of the pancreas with
metastases
into peripancreatic lymph nodes was diagnosed and completely resected. Fourteen months later, abdominal computed tomography and scintigraphy with (111)In-labeled octreotide suggested relapse of the tumor. The patient again had no evidence of Cushing's syndrome. A second in toto tumor resection was performed. Another 8 months later, the patient developed forgetfulness, depressive episodes, muscle weakness, new-onset hypertension, hypokalemia, plethora, diabetes mellitus,
polyuria
, and weight loss. Endocrine testing suggested a source of ectopic ACTH production. An octreotide scan showed an intense uptake ventromedial of the left kidney, an area that showed a mass lateral of the superior mesenteric artery on abdominal magnetic resonance imaging. A complete pancreatectomy with splenectomy and left-sided adrenalectomy were performed. At this second relapse, this neuroendocrine tumor clinically had changed its hormonal profile. Immunohistochemically, in contrast to primary tumor and first relapse, we found strong immunostaining for ACTH in tumor cells of the second relapse and a MIB-1 index greater than 20%. To our knowledge, this is the first report describing a pancreatic neuroendocrine tumor that started to secrete ACTH de novo at the time of the second relapse after two former complete tumor resections. This case underscores the pluripotency of neuroendocrine tumor cells and the importance of keeping in mind a possible shift in hormone production during tumor evolution and progression.

The finding of a polyuropolydispsic syndrome should prompt a complete biological investigation of its etiology. If
polyuria
can be a minor sign as in psychiatric disorder, it can also be the first manifestation of diabetes mellitus but also central diabetes insipidus, the latter linked to cerebral tumors,
metastases
in the hypothalamus, granulomatous disease, but also nephrogenic diabetes insipidus such as chronic renal disease or autoimmune disease. Intracellular dehydration is the major risk in case of a polyuropolydipsic syndrome. Prognosis depends on the capacity to maintain water balance through an intact thirst mechanism. After a brief review of the majority of causes of diabetes insipidus, we propose a diagnosis algorithm to easily make the diagnosis.

We present a case of late recurrence of breast cancer manifested with diabetes insipidus caused by isolated intracranial
metastases
. A 57-year-old postmenopausal woman was diagnosed with breast cancer and underwent radical mastectomy, without any adjuvant therapy. Seventeen years later, she presented with
polyuria
, polydipsia, weight loss, weakness, diffuse bone pain, hoarseness and mild dyspnoea. Cranial CT revealed several dural masses in the frontal, parietal and occipital lobes and along the falx cerebri. The diagnosis of central diabetes insipidus without impairment of anterior pituitary function was based on the clinical symptoms, laboratory tests and imaging findings. The patient was successfully treated with desmopressin acetate and letrozole, and remained alive and ambulating 22 months after initial presentation with diabetes insipidus.

Although uncommon, presentation of juxtaglomerular cell tumor is distinct and should allow a correct preoperative diagnosis in most patients. Typical clinical presentations include headaches,
polyuria
, or isolated, asymptomatic, severe hypertension. The diagnosis of a juxtaglomerular apparatus (JGA) tumor typically results from identification of plasma renin levels two- to sevenfold greater than the normal value. Although JGA tumors are considered benign, with no reports of
metastases
or recurrence, they are potentially lethal if left untreated. Surgical excision is curative.

The pituitary gland can be involved in a variety of medical conditions, including metastatic tumors.
Metastases
to the pituitary gland, although absolutely rare, more commonly affect the posterior pituitary lobe and so frequently present with diabetes insipidus. We report on a 48-year-old male heavy smoker patient suffering from sudden onset of
polyuria
and persistent thirst. Laboratory results revealed central diabetes insipidus. Computed tomography (CT) scan of the brain showed a mass located in the sella turcica and in the suprasellar region. CT scan of the chest showed a mass in the right superior lobe with mediastinal lymphadenopathy, with bronchoscopy and biopsy features of pulmonary adenocarcinoma. The patient received radiotherapy on the pituitary gland and adjuvant chemotherapy, and as intrasellar and suprasellar mass decreased in size, urinary output was accordingly reduced. Therefore, is that in patients with risk factors for cancer and sudden onset of diabetes insipidus pituitary metastasis should be taken into account in differential diagnosis.

A 54-year-old woman had been given a diagnosis with scleroderma and interstitial pneumonia due to scleroderma when she was 45 years old. Thirst, with resulting polydipsia and
polyuria
(about 7 liters/day) were present since May, 2004, and bloody sputum appeared in June of 2004. The patient was admitted to our hospital. Chest CT examination showed multiple nodules in the bilateral lower lung field and multiple movable subcutaneous nodules on the abdomen. Small-cell lung cancer (
metastases
in the pituitary, subcutaneous tissue, and lungs) was diagnosed by transbronchial lung biopsy and subcutaneous nodule biopsy of the abdomen. The final diagnosis was diabetes insipidus and Cushing syndrome. Chemotherapy was done with CDDP and VP-16, which resulted in reduction of the tumor and improvement in endocrinological findings. Nevertheless, chemotherapy could not be continued because of infected bullae. The patient died of deteriorating illness after 91 sickness days. We concluded that this case was Cushing syndrome caused by ectopic adrenocorticotropic hormone-producing small cell lung cancer, and that it presented with diabetes insipidus because of pituitary metastasis. Therefore, when drastic endocrinological changes are found, it is important to examine for cancer, including lung cancer, as soon as possible.

Tumor metastasis
to the pituitary gland has been infrequently reported, and this is probably because only a small proportion of these patients are symptomatic. Most of the symptoms of this malady are related to diabetes insipidus. A 78-year-old man was diagnosed 2 years previously with stage IIIA adenocarcinoma of the lung and treated with sequential chemoradiation therapy and later with whole-brain radiation therapy because of newly developed brain metastasis; he was then admitted to our hospital with symptoms of polydipsia and
polyuria
. He was confirmed to have central diabetes insipidus that was caused by the pituitary metastasis from lung cancer. His symptoms resolved after treatment with desmopressin. Because of the rarity of this manifestation in lung cancer patients, we report on this case along with a brief review of the relevant literature.

The pituitary gland and infundibulum can be involved in a variety of medical conditions, including infiltrative diseases, fungal infections, tuberculosis, primary and metastatic tumors.
Metastases
to the pituitary gland are absolutely rare, and they are generally secondary to pulmonary carcinoma in men and breast carcinoma in women. Pituitary
metastases
more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The posterior lobe involvement may explain why patients with pituitary
metastases
frequently present with diabetes insipidus. We are presenting a case report of a 48-year-old male patient with sudden onset of
polyuria
and persistent thirst. Laboratory results revealed central diabetes insipidus. Computed tomography (CT) scan of the brain showed a mass located in the sella turcica and suprasellar region. CT scan of the chest showed a mass in the right superior lobe with mediastinal lymphadenopathy. Bronchoscopy and biopsy demonstrated a pulmonary adenocarcinoma. Thus, we made a diagnosis of lung cancer with local and pituitary
metastases
. The patient received radiotherapy on the pituitary gland and adjuvant chemotherapy. As a result the intrasellar and suprasellar mass decreased in size and urinary output accordingly decreased. In conclusion, in patients presenting with sudden onset of diabetes insipidus pituitary
metastases
should be taken in account in differential diagnosis.

A 12-year-old, intact female beagle exhibited symptoms of
polyuria
-polydipsia and hyperorexia for two months. Blood tests showed elevated asparate aminotransferase, alanine aminotransferase, alkaline phosphatase and creatine kinase levels, as well as marked hypokalemia. The results of adrenocorticotropic hormone stimulation test showed elevated cortisol, aldosterone and corticosterone concentrations. Abdominal ultrasonography confirmed a mass in the left adrenal gland. Masses were also seen in the liver and caudal vena cava. Diagnosis was a tumor of the adrenal cortex with
metastases
. Trilostane administration was initiated. The dog initially showed improved demeanor as a result of regulating hormone secretion. However, after 88 days, the dog weakened rapidly, before dying on the 117th day. Pathological findings confirmed a diagnosis of adrenocortical carcinoma.

Pituitary metastasis occurs rarely in cancer patients and often remains undiagnosed. However, early detection and appropriate treatment can improve the patient's quality of life and possibly prolong survival. Herein, we describe the case of a 52-year-old woman with panhypopituitarism caused by
metastases
to the hypothalamus and pituitary from primary breast cancer. She had a 5-year history of breast cancer with
metastases
to the bones 1.5 years after initial diagnosis and mastectomy. She presented with severe headaches, generalized fatigue, dizziness, hypotension, difficulties with balance and coordination,
polyuria
, and polydipsia. Laboratory work-up revealed panhypopituitarism (central diabetes insipidus; hypothyroidism; and low prolactin, gonadotrophin, and adrenocorticotropic hormone levels), and magnetic resonance imaging confirmed the pituitary and hypothalamic involvement. She received hormone replacement therapy, radiation therapy of the sella turcica and suprasellar lesion, and chemotherapy, with significant improvement of her clinical status, but she died 15 months later.
