[Cyst of the ligamentum flavum of the lumbar spine: description of 6 cases]. / Kyste du ligament jaune lombaire: description de 6 cas.

Cysts of the ligamentum flavum of the lumbar spine have seldom been described. They are clearly visible in computed tomography as well as nuclear magnetic resonance, but are frequently wrongly diagnosed as ganglion or synovial cysts. The correct diagnosis is not feasible until after surgery. Such space occupying lesions can most often lead to uniradicular pain due to compression of a root. These cysts should be viewed as part of the degenerative process of the spine but not as tumor lesions. They need to be removed only in case of root entrapment. On the basis of six of our cases treated by surgery we describe the symptoms, imaging findings, operative techniques and pathological investigations.

[Pathologic-anatomic examination of prostatovesiculectomy samples in prostate carcinoma]. / Pathologisch-anatomische Untersuchung von Prostatovesikulektomiepräparaten beim Prostatakarzinom.

The incidence of the prostatic carcinoma as well as the cases treatable by radical prostatovesiculectomy with curative intention is increasing. The exact pathological examination of the specimens defines the stage of disease and subsequently the prognosis and therapeutic consequences. The compatibility of different scientific studies is made difficult by the lack of a standard in the pathological examination of the specimens. Our exactly defined rational method helps eliminate these troubles and ameliorate the interdisciplinary dialogue.
