    Description / Table of Contents: Summary The post-traumatic osteolysis of the distal clavicle is very infrequent and the etiology and pathology is poorly understood. It is important to consider this possibility for differential diagnosis when continued pain in the acromio-clavicular joint (AC joint) follows blunt shoulder trauma. The course of the disease may result in a 3 cm loss of length of the distal clavicle. Months and years may pass until osteolysis becomes manifest, but the earliest radiological findings are present 4 weeks after trauma. The disease is self-limiting and usually does not leave residues. We report a case of a 35-year-old man with a post-traumatic osteolysis of the distal clavicle after blunt shoulder trauma. The diagnosis was determined several months after pain persisted in his shoulder. Using this case we discuss the possible pathogenic mechanism, differential diagnosis and treatment options for the post-traumatic osteolysis of the distal clavicle.
    Notes: Zusammenfassung Die posttraumatische Osteolyse des distalen Klavikulaendes ist sehr selten und ihre Ätiologie sowie Pathogenese noch unbekannt. Es ist differentialdiagnostisch wichtig, diese Möglichkeit in Betracht zu ziehen, wenn persistierende Schmerzen im Akromioklavikular (AC)-Gelenk nach stumpfen Schultertraumen verbleiben. Dabei kann es zu einem Längenverlust der peripheren Klavikula von maximal 3 cm kommen. Monate oder Jahre können bis zur manifesten Osteolyse vergehen, wobei die ersten radiologischen Zeichen nach frühestens 4 Wochen zu sehen sind. Die Erkrankung ist selbstlimitierend und hinterlässt in der Regel keine Residuen. Wir berichten über einen 35-jährigen Mann mit einer posttraumatischen Osteolyse des distalen Klavikulaendes nach stumpfem Thoraxtrauma. Die Diagnose wurde erst mehrere Monate nach kontinuierlich bestehenden Schulterschmerzen gestellt. Wir diskutieren anhand dieses Fallberichts die mögliche Pathogenese, Differentialdiagnose und Therapie der posttraumatischen Osteolyse des distalen Klavikulaendes.

    Notes: Abstract Neither mammography nor cytology can distinguish precancerous tissue abnormalities from an infiltrative early carcinoma of the female breast. Radiologically detected microcalcifications can be the sole sign of precancerous stages or of already infiltrating mammary carcinoma. For this reason calcifications that are grouped together in a defined area or show up at a stage of multiple dissemination have to be resected and must be identified in the resected sample immediately. Between 1964 and 1990 we examined 82 163 women clinically, mammographically and in many cases sonographically at Erlangen University Hospital, FRG — by far the largest published series. In 1393 cases microcalcifications in the mammary tissues were resected and histologically diagnosed. In 1 in 4 cases we discovered a carcinoma or carcinoma in situ. The percentage we found (26.9%) corresponds with the results of other research groups. In order to avoid delays in the diagnosis of breast cancer effective cooperation between those physicians dealing with diagnosis and those performing surgery is essential. Mistakes can occur during a routine procedure, so we follow the principle that doubtful cases must be histologically evaluated.
