  • Title: Benign schwannoma in supraclavicular region: a false-positive lymph node recurrence of breast cancer suspected by PET scan.
    Author: Perniola G, Tomao F, Fischetti M, Lio S, Pecorella I, Benedetti Panici P.
    Journal: Arch Gynecol Obstet; 2014 Sep; 290(3):583-6. PubMed ID: 24744055.
    Abstract:
    INTRODUCTION: Positron emission tomography (PET) is the most accurate imaging modalities to detect malignancies. And it helps to take decisions regarding diagnosis, staging, recurrence, and therapeutical management. CASE PRESENTATION: We report a case of a suspected supraclavicular lymph node relapse, diagnosed by PET-CT in a breast cancer patient. The lymph node was surgically removed in outpatient with local anesthesia. Histological findings diagnosed a benign Schwannoma. In this patient PET-CT failed to distinguish benign tumors from metastatic supraclavicular lymph nodes. CONCLUSION: This case confirms the need to investigate histologically suspected supraclavicular lesions, during breast cancer follow up.
