Abstract
in English, German

SUMMARY: BACKGROUND: Ectopic breast tissue usually develops along the mammary ridges, and the incidence has been reported to be 2-6% of the general population. Occurrence of primary carcinoma in ectopic breast tissue is rare. CASE REPORT: We report the case of 59-year-old woman with accessory breast carcinoma in her left axilla. CONCLUSION: Because an accessory areola or nipple is often missing and awareness of physicians and patients about these unsuspicious masses is lacking, clinical diagnosis of accessory breast carcinoma is frequently delayed. Therefore, a mass along the 'milk line' should be examined carefully, and any suspicious lesions should be evaluated.

Hintergrund: Ektopisches Brustgewebe entwickelt sich gewöhnlich entlang der Milchleiste mit einer Inzidenz von 2–6% in der allgemeinen Bevölkerung. Das Auftreten primärer Karzinome in ektopischem Brustgewebe ist selten.

Fallbericht: Wir berichten von einer 59-jährigen Patientin mit einem Mammakarzinom in einer akzesso-rischen Brustdrüse in der linken Axilla.

Schlussfolgerung: Da akzessorische Warzenhöfe oder Brustwarzen zumeist nicht vorhanden sind und sowohl Ärzte als auch Patienten die meist unverdächtigen Knoten oft nicht zur Kenntnis nehmen, ist die klinische Diagnosestellung bei Mammakarzinomen akzessorischer Brustdrüsen regelmäßig verzögert. Ein Knoten entlang der Milchleiste sollte daher eingehend untersucht und verdächtige Läsionen genauer geprüft werden.

A Film Mammography shows an approximately 2.0-cm, lobulated mass with spiculated margin and pleomorphic, clustered microcalcifications in the left axilla. B Ultrasonography of the left axilla shows an approximately 1.7-cm, ill-defined, heterogenous, and hypoechoic mass with hyperechoic rim. C Breast magnetic resonance examination shows an approximately 1.7-cm, round, homogenous, and low signal intensity mass in the left axilla.
