Abstract
in English, German

BACKGROUND: Nodular fasciitis of the breast is a rare benign pathology that can mimic breast cancer clinically, radiologically, and histopathologically. CASE REPORT: An 18-year-old female patient had first visited a physician in a different center with the complaint of a lump in her left breast. Breast examination had revealed a palpable mass located in the left upper outer quadrant. Ultrasonography had demonstrated a hypoechoic lesion. Excisional biopsy of the lump had been performed and histopathologic examination misdiagnosed this lump as a mesenchymal tumor. The patient was then referred to our clinic for further investigations. Pathologic revision was performed and the diagnosis of nodular fasciitis of the breast was established. CONCLUSION: Awareness of this rare clinical entity, nodular fasciitis, in the breast eliminates the misdiagnosis of breast cancer.

Hintergrund: Die noduläre Fasciitis ist eine seltene benigne Erkrankung der Mamma, die klinisch, radiologisch und histopathologisch Brustkrebs imitieren kann.

Fallbericht: Wir stellen den Fall einer 18 Jahre alten Patientin vor, die wegen einer Geschwulst in ihrer linken Brust in einer anderen Klinik vorstellig wurde. Die dortige Untersuchung ergab einen palpablen Knoten im linken oberen äuβeren Quadranten. Die Sonographie zeigte eine hypodense Raumforderung. Es folgte eine Exzisionsbiopsie mit einer histopathologischen Untersuchung, die diesen Knoten als mesenchymalen Tumor deutete. Zur weiteren Untersuchung wurde die Patientin in unsere Klinik überwiesen. Nach Überprüfung der histopathologischen Diagnose musste diese revidiert werden. Es zeigte sich das Bild einer nodulären Fasciitis und die Einweisungsdiagnose Tumor wurde verworfen.

Schlussfolgerung: Das Wissen um die Möglichkeit dieser seltenen Erkrankung, noduläre Fasciitis, könnte die Fehldiagnose Mammakarzinom vermeiden.
