[Massive hypertrophy of the mammary gland. Report of 6 cases].

In the period of January of 1985 to January of 1995, 6 cases of massive hypertrophy of the mammary gland were diagnosed from 60,000 patients seen in the External Consultation of the Service of Gynecological Oncology. The age oscillated between 11 and 27 years old, with an average of 20.8 years. One case was unilateral and the 5 remaining, bilateral; 3 coexisted with pregnancy. The treatment consisted of reductive mammoplasty. This pathology is a rare entity, with not very well defined etiology in which apparently there are involved hormonals receptors and an unusual sensibility to hormones although they are at normal serum levels.
