Abstract
Histopathological study for stromal cellular response was made on 200 cases of benign and dysplastic lesions and malignancy of breast. Infiltrations with lymphocytes and plasma cells were observed in 64% cases of fibroadenoma, 66.6% cases of giant fibroadenoma, 61% cases of mammary dysplasia and 33.3% cases of gynaecomastia. While mast cell infiltration was not observed in giant fibroadenoma, its presence was observed in 92% cases of fibroadenoma, 77.8% cases of mammary dysplasia and 33.3% cases of gynaecomastia. Lymphocytes and plasma cells infiltrations were observed in 100% of cases of invasive duct carcinoma, medullary carcinoma and fibrosarcoma. Comedocarcinoma showed infiltration with these cells in 75% of cases while that for colloid carcinoma and Paget's disease of breast were observed in 50% of cases of each. Infiltrations with mast cells were observed in 92.3% cases of invasive duct carcinoma, 75% cases of comedocarcinoma and 25% cases of medullary carcinoma. Other malignant conditions of breast did not show mast cell infiltration. Degree of infiltration with lymphocytes and plasma cells was mainly of low grade in benign and dysplastic lesions compared to high degree of infiltration in malignancy. Mast cell infiltration was of low degree in both the types of lesions.
