Gestational gigantomastia: a patient case review and literature review

Abstract

Gestational gigantomastia (GG) or gravidic macromastia is defined as a disorder characterized by a diffuse, extreme and incapacitating enlargement of one or both breast during pregnancy. Gestational Gigantomastia is a very rare condition with a little over a 100cases reported in history. Gigantomastia has been seen to occur in the face of normal hormonal profile. Due to increase in breast mass, the overlying skin is stretched and may undergo necrosis which in the face of pregnancy can cause severe mastitis and haemorrhage.

We present a rare case of GG in a 36-year-old para 7 gravida 8, Zambian woman at 28weeks gestation with classical features of typical GG with normal hormonal profile with respect with pregnancy. She was managed conservatively on Bromocriptine 5mg once a day during pregnancy and postpartum until breast size had reduced to near normal prepregnancy size.

We report a rare case of “True gigantomastia which develops rapidly during pregnancy, undergoes regression after delivery, and recurs with subsequent pregnancies” in Zambia.
