[The significance of mammographic symptoms in clinically occult findings].

The significance of various radiographic signs in 183 patients with clinically occult breast disease is described. 30.6% had a carcinoma of the breast or a carcinoma in situ. The radiological features have varying predictive values and there is variation in the incidence of lymph node metastases. It is considered useful to classify the radiological appearances under the headings of round foci, star-shaped opacities, diffuse opacities, opacities with calcification and groups of micro-calcification. Despite the early diagnosis, 24% of patients already had lymph node metastases.

[Initial experiences with the "Mammotest" stereotactic diagnosis system in the diagnosis of roentgenologically unclear changes in the breast].

The article reports on first experiences with the stereotactic diagnosis device "Mammotest" in the diagnosis of diseases of the breast. Preoperative stereotactic carbon marking of non-palpable changes requiring clarification via mammography was successful in 94% of the cases. With the stereotactic cytological clarification by means of Nordenström's cannula the high rate of cellular material which could not be clarified, was unsatisfactory. Stereotactic histological punch biopsy in case of unclear mammographic findings enables exact localisation of the punch and histological examination of the punch biopsy. Mammographic follow-up did not yield any false negative finding to date.
