Tubular carcinoma

Tubular carcinoma is a subtype of invasive ductal carcinoma of the breast.[1][2] More rarely, tubular carcinomas may arise in the pancreas[3] or kidney.[4] Most tubular carcinomas begin in the milk duct of the breast and spread to healthy tissue around it.[5][6]

Pathology

Although tubular carcinoma has been considered a special-type tumor,[lower-alpha 1] recent trend has been to classify it as a low-grade, invasive NOS carcinoma because there is a continuous spectrum from pure tubular carcinomas to mixed NOS[lower-alpha 2] carcinomas with tubular features, depending on the percentage of the lesion that displays tubular features.[9]: 647 

Histology

Tubular carcinomas are generally around 1 cm. or smaller, and are made up of tubules. They are usually low-grade.[1] Elastosis has been noted as common but is not present in all cases.[10]

Prevalence

Prevalence has previously been controversial, with contradictory reports from studies reporting either very low prevalence, or a high prevalence.[9] With the increasing availability of screening mammography, however, tubular carcinomas are being diagnosed earlier, and more recent studies suggest tubular carcinomas represent between 8% and 27% of all breast cancers.[1]

Prognosis

Tubular carcinoma is one of the histologic types of breast cancer with a more favorable outcome.[11]
