MALIGNANT LESIONS: Out of the 50 cases diagnosed as malignant lesions, 38 cases were diagnosed as invasive ductal carcinoma, 5 cases as mucinous carcinoma, 2 invasive lobular carcinoma and 1 case each of CA breast, comedo carcinoma, medullary carcinoma, papillary carcinoma and tubular carcinoma
Tumours are small in size than IDC but similar to tubular carcinoma
ranging from 0.

4-10) It was actually first recognized by Japanese investigators in the mid 1990s and then was proposed to be named intraductal tubular carcinoma
by the Japan Pancreas Society in 2002.

MYOEPITHELIAL-NEGATIVE SMALL GLANDULAR PROLIFERATIONS--MGA AND TUBULAR CARCINOMA
Invasive tubular carcinoma
(ITC) is considered to be an indolent tumor having an excellent prognosis and typically shows high levels of ER and PR expression.
Immunohistochemical detection of maspin is a useful adjunct in distinguishing radial sclerosing lesion from tubular carcinoma
of the breast.
(TC) of the breast is uncommon, comprising fewer than 2% of invasive breast carcinoma cases.
