The diagnostic accuracy of these two modalities were calculated. Results: Of 104 Patients, 43 had breast cancer and 61 had benign lesions, the sensitivity and specificity for mammography were 84% and 83%, 82% and 77% for infrared lightscanning. The predictive values of positivity for mammograpby and lightscanning were 80% and 70%, the negative Predictive value for these two modalities were both 87%. Conclusion: Infrared lightscanning,being of assistance to mammography, could enhance sensitivity and predictive values of positivity in detecting breast cancer, especially, in mammographically dense breast.展开更多

Methods: All of the 184 patients with breast diseases underwent mammography before either an open biopsy or a mastectomy. The presence, morphology, and distribution of calcifications visualized on mammograms for breast cancer were compared with the controls who remained cancer free. Statistical comparisons were made by using the x 2 test. Results: Of the 184 patients with breast diaeases, 93 malignant and 91 benign lesions were histologically confirmed. Calcifications were visualized on mammograms in 60 (64%)of 93 breast cancers and 26(28%)of 91 non breast cancers. The estimated odds ratio (OR) of breast cancer was 4.5 in women with calcifications seen on mammo grams, compared with those having none ( P < 0.01). Of the 60 breast carcinomas having mammographic calcifi cations, 28 (47%) were infiltrating ductal carcinomas. There were only 8 (24%) cases with infiltrating ductal cancers in the group of without calcifications seen on the mammograms ( P <0.05). Conclusion: Our finding sug gests that mammographic calcification appears to be a risk factor for breast cancer. The granular and linear cast type calcification provide clues to the presence of breast cancer, especially when the carcinomas without associated masses were seen on mammograms.展开更多

On clinical examination, a solitary, firm nodule was found in the subcutaneous tissue of the left breast with no changes in the overlying skin. Radiological examination showed disconcordant results. Conventional mammography and ultrasound suggested benign nature, while magnetic resonance mammography and spectroscopy raised the presumption of the malignant nature of the lesion. After performing excisional biopsy, the diagnosis of trichoblastic fibroma was established. Microscopically, it was composed of fibrous stroma, basaloid germs and strands and lace-like epithelial components, with no obvious connection with overlying epithelium or adjacent adnexal structures.展开更多
