title: [Difficulties and errors in the cytological diagnosis of breast cancer].
abstract: The paper deals with retrospective evaluation of cytograms of tumor punctates from 142 patients with breast cancer. It was found that adequate diagnosis is hard to make in cases of lobular and scirrhous carcinoma due to indistinct atypia of cells and nuclei. Errors in cytological diagnosis may arise both from absence of cell structure in tapping material and misinterpretation of morphological features of malignant cells in scirrhous carcinoma and highly-differentiated lobular cancer.
