Gigantomastia gravídica asociada a tejido mamario ectópico vulvar

We report the case of a primigravida who had previously undergone breast reduction and who developed gigantomastia associated with a vulvar adenoma, diagnosed as an ectopic mammary adenoma. Despite its low frequency, physicians should be familiar with this entity due to its major effects on the patient and health team, requiring decisions with important repercussions on the health - and sometimes life - of the woman and fetus.
