[Ectopic thyroid tissue with a primary carcinoma].

Ectopic thyroid tissue is a result of abnormal embryologic development and migration of the thyroid gland. It has a prevalence of one per 100,000-300,000, and the risk of malignant transformation in ectopic thyroid tissue is rare. We present a rare case of perivesical ectopic papillary thyroid carcinoma in a 76-year-old man with a normal orthotopic thyroid gland.

[Breast carcinoma metastasis to the gastrointestinal tract and tumour-to-tumour metastasis to renal cell carcinoma].

Breast carcinoma metastasis to the gastrointestinal tract and tumour-to-tumour metastasis is rare. We describe a case of a 71-year-old woman with previous breast cancer presenting with dyspepsia, nausea and weight-loss. Biopsies from the pylorus revealed what appeared to be a gastric carcinoma.

[Emphysematous pyelonephritis in a non-diabetic patient with a kidney tumour].

Emphysematous pyelonephritis (EPN) is a potentially life-threatening infection, where gas produced by bacteria accumulates in the kidney and the surrounding tissue. Although EPN usually presents in diabetic women, it is also associated with urinary tract obstruction and kidney tumours in non-diabetic patients. We present a case of EPN in a non-diabetic patient with a known kidney tumour, successfully treated with double-J catheter, antibiotics and delayed nephrectomy.

[Prostate cancer presenting with diffuse infiltration of metastases to the pancreas].

Prostate cancer is the most common cancer, when excluding skin cancer, among males in Denmark. Prostate cancer usually metastasizes to regional lymph nodes and distantly to bone, lung, and liver. In the literature, there are only a few cases describing metastases to the pancreas.

Hand-assisted partial nephrectomy with early arterial clamp removal: Impact of the learning curve.

Objective: The aims of this study were to present the results of hand-assisted laparoscopic partial nephrectomy according to the margin, ischaemia and complications system; to assess the role of the learning curve; and to compare this approach with other approaches.

Material And Methods: Data from 60 consecutive patients were obtained from a prospectively maintained database. The patients were divided into three cohorts (1, 2 and 3), with 20 patients each, according to their surgery dates.

[Complications after treatment of colorectal cancer, with special focus on stomas, urological conditions and sexual dysfunction].

In spite of improved surgical principles in colorectal surgery, patients undergoing this operation still suffer from long-term postoperative complications. Many patients have permanent stomas, and up to 60% have problems related to their stomas, the most frequent of these being parastomal hernia. In this context, the use of primary prophylaxis with mesh insertion is encouraging.

[Blunt isolated pancreatic trauma. Diagnostic problems--a clinical and radiological challenge].

Introduction: Blunt isolated pancreas trauma is rare, but it is a very serious condition. Diagnosis and treatment are often delayed, which considerably increases morbidity. The delay is caused by uncharacteristic symptomatology and the application of paraclinical and radiological diagnostic methods of low initial sensitivity and specificity.
