title: [Hamartomas of the breast. Apropos of 14 histologically controlled cases].
abstract: 14 cases of mammary hamartomas are reported. The WHO describes the mammary hamartoma, as a pseudo-tumor made of ducts and lobules, with fibrosis or adipose connective tissue. The mammogram consists in a well circumscribed tumor generally surrounded by a defined zone of less attenuation. Surgically, the hamartoma can usually be enucleated. Microscopy reveals lobules always but inconstant adipose tissue. Confrontation between gross and histologic features are necessary for the diagnosis. The embryologic development of the mammary gland could help to explain the origin of such a lesion, malformative rather than tumorous.
