Background: The brachial plexus’ neurilemmoma is an extremely rare neoplasia.
Case Report: A 61 years old woman came to our hospital with a clinical history of serum-hematic secretion from the right nipple. The physical examination was otherwise unremarkable. She had a negative mammography, while in the right retro-areolar section the ultrasound examination showed an ipoechoic lesion, with well defined margins, consistent with a papilloma and/or an intracanalicular fibroadenoma. In the left axilla, a solid capsulated, homogeneous, vascularized nodule was detected, non-univocally interpretable, suspicious for malignancy. The fine needle aspiration biopsy was consistent with mesenchimal neoformation, uncertain whether benign or malignant.
Conclusions: After surgical removal the pathological diagnosis was: neurilemmoma.
