Unilateral gestational macromastia--an unusual presentation of a rare disorder.

Macromastia (mammary gigantism) is an uncommon clinical entity. Macromastia occurring during pregnancy (gestational macromastia) is rare. A case of unilateral gestational macromastia is reported which required reduction mammoplasty. We documented hyperprolactinaemia in the patient. This case report is particularly interesting because, to our knowledge, no such case has previously been reported.
