The ''Rosen Triad'': tubular carcinoma
, lobular carcinoma in situ, and columnar cell lesions.
Immunohistochemical detection of maspin is a useful adjunct in distinguishing radial sclerosing lesion from tubular carcinoma
of the breast.
Syringomatous adenoma of the nipple is a benign, but locally aggressive, tumor that is often misdiagnosed as tubular carcinoma
Interestingly, the neoplastic cells of LIN showed the same monoclonal pattern as the adjacent flat lesion and tubular carcinoma
(clonally related neoplastic breast lesions).
Intraductal tubular carcinoma
of the pancreas: clinicopathologic and immunohistochemical analysis of 18 cases.
On review, these cases could be separated into either small acinar proliferations suspicious for tubular carcinoma
, intraductal proliferations consistent with ADH, or proliferative fibrocystic changes with atypia.
Histologically, the 5 "upstaged" cases consisted of 3 infiltrating ductal carcinomas (1 grade 1/3 and 2 grade 3/3), 1 infiltrating lobular carcinoma (grade 2/3), and 1 tubular carcinoma
It is estimated that upto 550 of these will be breast cancer patients with a variety of subtypes, such as invasive ductal carcinoma, invasive lobular and tubular carcinomas
, and in-situ carcinoma ductal.
Another 16 of the lesions were found to be infiltrating ductal carcinomas, 2 were invasive tubular carcinomas
, 2 were ductal carcinoma in situ, 1 was invasive lobular carcinoma, and 1 was a mixed infiltrating ductal and lobular carcinoma, according to Dr.
