Zusammenfassung

Ektopien des Mammagewebes können die gesamte Brust (akzessorische Mamma), den Drüsenkörper ohne Mamille (aberrierende Mamma) oder nur die Mamille betreffen (Polythelie). Sie entwickeln sich entlang der von der vorderen Axillarfalte bis in die Vulva reichenden, als Milchleiste bezeichneten embryonalen Anlage, sehr selten auch außerhalb davon. Die häufigsten Lokalisationen sind die Axilla, die reguläre Mamma und ihre unmittelbare Nachbarschaft. Von ektopen Mammagewebe ausgehende Tumoren wie Fibroadenome und Karzinome sind in Einzelfällen beschrieben.

Abstract

Ectopic breast tissue may represent the complete breast (accessory breast), glandular tissue without areola or nipple (aberrant breast tissue), or exclusively the nipple (polythelia). Localization is along the embryonic milk ridge extending from the axilla to the vulva. Only rarely, is ectopic tissue found outside of the milk ridge. Most frequently affected are the axilla, the breast itself, and its close neighbourhood. Ectopic breast tissue may rarely give rise to tumours such as fibroadenoma or carcinoma.
