Role of fine needle aspiration and tru cut biopsy in diagnosis of mucinous carcinoma of breast—from a radiologist's perspective

This study was to assess whether fine needle aspiration (FNA) or core biopsy would allow diagnosis of mucinous carcinoma of breast. In 37 mucinous carcinoma in 34 patients, 20 lesions had FNA and 24 lesions with core biopsy. FNA achieved a sensitivity of 66.7% in diagnosis of malignant lesions and 56% sensitivity in diagnosis of mucinous carcinoma. Core biopsy achieved 100% sensitivity and accuracy in the diagnosis of malignant lesions and mucinous carcinoma.
