The ultrastructure of tubular carcinoma of the breast.
The ultrastructure of four tubular carcinomas of the breast is described. The neoplastic tubules are single layered and lack a myo-epithelial component, an important feature in distinguishing tubular carcinoma from sclerosing adenosis. Numerous myo-fibroblasts are present in the stroma of all four tumours and, since cells of this type have been recorded only occasionally in the stroma of other types of breast carcinoma, it is suggested that they may be a characteristic feature of tubular carcinomas.
