[Signs of secretion in the mastopathic breast (author's transl)]

Nuclei of the epithelia of the ducts can enter into the tongue- or clublike protrusion, which is characteristic of apocrine secretion. Together with the protrusions the nuclei may be discharged into the lumen, an occurrence one could call apocrine estrusion of nuclei. It can be found up to the sixth decade. II. Occasionally single lobuli show all signs of a fat- (milk-) secretion of fat (milk) and of apocrine estrusion of nuclei, leading to the formation of elements resembling colostrum bodies as they occur in the milk. The cases involved as a rule menstruating women. The secretion, therefore, seems to be due to hormonal influence on especially sensible lobuli of the mastopathic breast.
