At the beginning of inpatient rehabilitation, patients with thyroid cancer often experience more problems than controls from community samples, independent of their age and gender. Clinicians should be aware of the fact that quality of life is not directly related to the severity of the cancer prognosis.

The results of functional and structural imaging in PLE may differ substantially. Results of FDG-PET can demonstrate focal hypermetabolism over a long time, which may indicate therapeutic potential. A prospective study with more patients will be needed to clarify the relevance of PET as a possible outcome measure in PLE. Future studies should include scalp or semi-invasive electroencephalographic recordings during PET acquisition.

The increased In-111 pentetreotide and Ga-68 DOTATOC uptake in active Hashimoto's disease is most likely related to the lymphocytic infiltration of the thyroid. However, the physiologic or pathophysiologic relevance of the increased In-111 pentetreotide and Ga-68 DOTATOC uptake in normal thyroid glands, hot and cold nodules, and goiters and nodular thyroids remain to be determined.

Background: ACTH overproduction within the pituitary gland or ectopically leads to hypercortisolism. Here, we report the first case of Cushing' syndrome caused by an ectopic ACTHsecreting neuroendocrine carcinoma of the mesentery. Moreover, diagnostic procedures and pitfalls associated with ectopic ACTH-secreting tumors are demonstrated and discussed.

SUMMARYBackground: Recent decades have seen a rise in the incidence of welldifferentiated (mainly papillary) thyroid carcinoma around the world. In Germany, the age-adjusted incidence of well-differentiated thyroid carcinoma in 2010 was 3.5 per 100 000 men and 8.7 per 100 000 women per year.

Laparotomy with tumor resection. Reduction of antihypertensive medications. Further follow-up by MRI, hybrid 123I-MIBG SPECT-CT and testing for plasma catecholamines and free metanephrines.

Cushing's syndrome can be caused by adrenocorticotropic hormone-secreting solid tumors. We report a rare case of an ileal endocrine carcinoma that produced ACTH and induced hypercortisolism. A now 47-year-old man presented at age 41 with weight gain, tremor, perspiration, and general fatigue. Laboratory testing showed hypercortisolism and diabetes mellitus. Further examinations revealed ectopic Cushing's syndrome. The search for the primary tumor was difficult. The patient underwent subtotal thyroidectomy and surgical removal of a pituitary lesion. After resection of an ACTH-producing metastasis of the mesentery, temporary remission of Cushing's syndrome ensued. At the age 45 the primary tumor was detected in the ileum by Ga-68 DOTATOC-PET scan and explorative laparotomy. After surgical removal of this well differentiated neuroendocrine carcinoma the patient significantly improved clinically. He experienced better blood pressure and remission of his diabetes mellitus in addition to increased muscular strength. Endocrine laboratory testing at follow-up examinations confirmed remission of hypercortisolism and diabetes mellitus. A Ga-68 DOTATOC PET scan and a 1 mg dexamethasone suppression test 5 months after surgery showed normal results. Ectopic ACTH secretion within the small bowel is very rare. This case underscores the difficulty in locating the source of ectopic ACTH secretion and suggests using small bowel barium study, tubus endoscopy or video endoscopy for preoperative localization if the small bowel is suspected as tumor source.
