ABSTRACT

Gestational gigantomastia is a rare pathology resulting in diffuse and excessive breast growth during pregnancy. Its incidence is estimated at 1 case / 100,000 pregnancies. It is thought to be linked to an exaggeration of the physiological hyperplastic phenomena of pregnancy caused by an increase in oestrogen or progesterone receptors. It is associated with the appearance of ulcerations and cutaneous necrosis of the breast, which brings into play the maternal prognosis and the pregnancy. Although benign, it can lead to a great social, emotional and physical handicap. In the rare cases reported in the literature, the treatment of gestational gigantomastia has varied on a case-by-case basis depending on the team and the presence or absence of complications. Medical treatments have been proposed mainly based on bromocriptine and reduction or radical surgical interventions (bilateral mastectomy) have been justified in cases which do not regress or which present significant complications. We report the case of a 32 year old patient who presented a gestational gigantomastia from the 14th week of amenorrhoea and who was put on bromocriptine with the result of a good neonatal outcome and a very favourable evolution in post partum with total regression of the volume of both breasts.
