90 cases of simple, radical and modified radical mastectomized breast carcinoma were studied to compare the degree of elastosis in cancer through Verhoeff van Gieson stain with histologic types, tumor border, stromal amount, lymph node metastasis, age and the degree of elastosis in adjacent breast tissue. Elastosis was 77.0% in adjacent normal breast tissue and 82.2% in breast carcinoma. Moderate to marked degree of elastosis were related to the degree of connective tissue stromal amount and tumor border. Breast carcinoma with moderate to marked elastosis showed frequent lymph node metastasis.
