[Diagnostic accuracy of prostate needle biopsies in cancer of the prostate].

The carcinoma of the prostate can be diagnosed with high certainty in needle biopsy. Among 450 cases only one false diagnosis was found. Under routine diagnostic conditions, semiquantitative evaluation showed that 50% of the investigated morphological parameters in carcinomas of the prostate can be reproduced by one and the same or different investigators with a sufficiently high degree of certainty. Comparison between needle biopsy and transurethral resection material showed that the overall coincidence of tumor classification (according to the predominant part of tumor) was only 50%. The authors conclude that tumor therapy should not predominantly be based on morphology present in a single needle biopsy.

[Prognostic significance of clinical and morphological parameters in prostate cancer].

In 269 patients with carcinoma of the prostate, a retrospective statistical evaluation was done to correlate prognosis with different clinical and morphological criteria. All prostate biopsies were reviewed, the clinical staging redone and compared to survival of the patients. The most reliable criteria for prognostic prediction are clinical staging (rectal palpation, radiological examination and prostatic acid phosphatase). The morphologic parameters (histologic type of tumor, perineural invasion and perifocal inflammation) are of additional but of limited value.

[Cranial mucormycosis in a patient with a transplanted kidney].

Mucormycosis is a very serious complication of debilitating diseases, and particularly of diabetes. Presently the treatment of choice is amphotericine B. A patient is described who, like most other renal transplant patients with mucormycosis, had cranial localization of this disease and diabetes. The clinical findings were classical and the diagnosis was confirmed histologically.

[Tuberous sclerosis in a premature infant (author's transl)].

A sporadic case of tuberous sclerosis in a stillborn infant is reported. The death at the 31st week of gestation was presumably due to the development of enormous rhabdomyomas of the heart. The typical cerebral lesions were fully developed as in patients decreased later in life. The atypical cells found in the cortical tubers demonstrated ultractructural features of reactive astrocytes. Moreover, they showed innumerable microvillilike projections on their surface and junctional complexes, mostly of the zonula adharens type, reminescent of ependymocytes. The significance of such glio-epithelial cellular features is discussed.
