Tubular carcinoma of the breast. A study of frequency.

Tubular carcinoma of the breast is a recognizable histologic type of invasive mammary carcinoma, characterized by infrequent axillary lymph nodal metastases and an excellent prognosis. Of all carcinomas of the breast diagnosed in 1974 in the Louisville area, 42, or 10.3% were of the tubular variety. This is in contrast to the previously expressed opinion that tubular carcinoma is rare. Three histologic types of tubular carcinoma are described. Strict criteria for diagnosis of the mixed type are recommended.
