We report the association of gigantomastia during pregnancy and a lactating adenoma in ectopic breast tissue of the vulva in a context of myasthenia in a 27-year-old primigravid woman. We discuss the pathophysiologic condition and management of gigantomastia that involves ectopic breast tissue during pregnancy.
