[Diagnosis and differential diagnosis of extraskeletal, para-articular chondroma of the knee].

AIM: Extraskeletal chondromas in the region of the knee joint are very rare tumors which may cause diagnostic problems and have concomitant therapeutic consequences. METHOD: In a case report we present the clinical, radiological and histological features of an a extraskeletal chondroma. RESULTS: A 47-year-old female patient presented with an infrapatellar, painless tumor of the knee joint. The clinical features were unspecific. On plain X-ray images, calcifications were visabled within Hoffa's fat pad. An important preoperative imaging procedure was MRI, which showed a well defined mass of 2.5 cm in diameter with a hyperintense signal on fat suppressed images. Subsequent operative therapy involved marginal resection of the tumor. CONCLUSION: The differentiation of this entity especially from myxoid chondrosacroma and synovial chondroamatosis was crucial with respect to an adequate therapy. Further differential diagnoses included heterotopic ossifications, synovial sarcoma, mesenchymoma and soft-tissue osteosarcoma.

[Intestinal infection, the most frequent cause of invagination in childhood: results of a 10-year clinical study].

BACKGROUND: Intussusception is the most common cause of an acute abdomen in early childhood. 90% of all intussusceptions were thought to be idiopathic, because no lead points could be evaluated. PATIENTS: In our study we examined 148 children (93 boys and 55 girls) between 2. month and 18. years of age with 155 intussusceptions. METHOD: Besides epidemiological features and patients history we determined systematically all symptoms which occurred since the beginning of sickness. We performed ultrasound examinations before and after hydrostatic reduction with each child in order to find pathologic lead points. Microbiologic stool examination could be carried out at 99 specimen. RESULTS: 41 of 155 children with intussusception (26.5%) showed a pathologic finding next to the intussusception, with 29 children (18.7%) suffering from mesenteric lymphadenitis. 60.6% of examined stool specimen were abnormal. The most common germs were adenovirus, yersinia and staphylococcus aureus. Abdominal pain was the main symptom and was found in 72.6% of all children. 21% suffered from the classic trias abdominal pain, vomiting and rectal bleeding. 21.9% had diarrhea and 18% fever and signs of inflammation as unspecific symptoms. CONCLUSIONS: In our study we found mesenteric lymphadenitis as the most common lead point in intussusception. In conclusion with 60.6% pathologic germs in the examined stool specimen we assume gastrointestinal infection as the main cause of intussusception in childhood.
