BACKGROUND: Differentiating a distant lesion in breast cancer patients can be challenging. Although pleural schwannoma in breast cancer patient is unusual, clinicians may encounter many similar benign lesions mimicking metastatic breast cancer.
CASE REPORT: Herein, we present the case of a 62-year-old female patient who developed schwannoma on her pleura, which was suspected as metastasis of breast cancer.
CONCLUSIONS: Our case highlights the need to keep in mind the non-malignant diagnosis of distant lesion in those with malignancies, such as breast cancer.
