carcinoma:

see neoplasmneoplasm
or tumor,
tissue composed of cells that grow in an abnormal way. Normal tissue is growth-limited, i.e., cell reproduction is equal to cell death. Feedback controls limit cell division after a certain number of cells have developed, allowing for tissue repair

The important feature of invasive cribriform breast cancer is the cribriform growth pattern that is used for differentiation from tubular carcinoma. Cases with a component of another carcinoma type accompanying cribriform pattern are regarded as mixed type invasive cribriform cancer and have less favourable outcome than pure cribriform cancers (28).
Tubular carcinoma of the breast is a well-differentiated type of invasive ductal carcinoma that forms neoplastic tubules mimicking breast ductules and accounting for about 1% of all breast carcinomas [7].
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 0.5-2.5 cm.
The mean ADC value of tubular carcinoma was calculated (0.85[+ or -]0.16x10-3 mm2/s) as lower than the mean ADC value of normal parenchyma (1.25[+ or -]0.25x10-3 mm2/s) (Figure 2).

An adenosis and pseudo infiltrative pattern were also prominent in the present case, and resembled invasive tubular carcinoma or adenosquamous carcinoma.
Microglandular adenosis of the breast--a lesion simulating tubular carcinoma. Histopathology.
(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 of the breast: a lesion simulating tubular carcinoma. Histopathology.
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.
