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.

An adenosis and pseudo infiltrative pattern were also prominent in the present case, and resembled invasive tubular carcinoma or adenosquamous carcinoma.

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.
Microglandular adenosis, apocrine adenosis, and tubular carcinoma of the breast: an immunohistochemical comparison.
It is characterized by positive S100, negative estrogen receptor (ER), and negative progesterone receptor (PR) immunohistochemical stains and positive basement membrane stains such as collagen type IV and laminin, contrasting with tubular carcinoma, for which it is often mistaken.
20) Many subtypes of invasive breast cancer, such as invasive tubular carcinoma (ITC), medullary carcinoma (MC), and invasive mucinous carcinoma (IMC), have traditionally been considered to be associated with a more favorable prognosis, while others such as invasive micropapillary carcinoma have been thought to be associated with a poor outcome.
