Juvenile polyposis was first described by Cronkhite and Canada in 1955. This disease is characterized by juvenile intestinal polyps and ectodermal abnormalities. The etiology of Cronkhite-Canada syndrome (CCS), however, is still not well understood. Interestingly among patients with CCS a significant correlation (16.5%) with intestinal carcinomas has been observed. Thus, malignant transformation and/or genetic predisposition may be involved in the initiation of the disease. In the following, epidemiology, symptoms, morphology and therapy of CCS are discussed. Our examinations are based on studies reported in the literature and on a case report of a female patient who developed a colon carcinoma 2 years after initial diagnosis of CCS.

Successful patient care of the injured shoulder of a hockey player involves interdisciplinary cupertino. Images allow an interpretation of a static dimension but may not be sufficient enough to develop a surgical treatment strategy, since all injuries to the shoulder have its origin in a dynamic pathology with some kind of external impact. This article classifies various traumatic shoulder problems and the mechanism of injury, it outlines clinical tests and stresses key facts an imaging report should include in order to plan conservative or surgical treatment. Basic treatment options as performed in our institution for the injured shoulder of a hockey player are summarised briefly.
