[Paget's disease of ectopic breast].

DISCUSSION: An ectopic breast, present in 6 % of the population, is often ignored, despite being subject to the same diseases as anatomical breasts: it is at the origin of 0.6 % of breast cancers. Paget's disease is a rare in situ adenocarcinoma comprising fewer than 3 % of cases of breast cancer. It is extremely rare in ectopic breast. Ours is only the fourth reported case in the literature. This case is original because of the lack of objective clinical signs. Subjective symptoms such as pain, tingling, burning sensation and pruritus related to the supernumerary breast must be taken into consideration in order to enable early diagnosis of Paget's disease. Exploration by ultrasound and mammography generally appears flawed. Breast MRI may be useful but is not performed routinely. A promising future approach may consist of confocal microscopy screening of all ectopic breasts with areola or nipple patches, since this method enables the visualization of Paget cells and their organization.
