Abstract
Pleuropulmonary spindle cell carcinoma (SpCC) is a very rare tumor that belongs to a subgroup of sarcomatoid carcinomas of non-small cell carcinomas of the lung. Breast carcinoma is one of the most common malignancies associated with metachronous second primary cancers. To our knowledge, this is the first report of a rare case of multiple pleuropulmonary SpCC in a 70-year-old woman, 16 years after mastectomy and chemotherapy for breast carcinoma.
