Discussion:
Operative report: palpable 2x2cm mass in the mediastinal surface of the rt middle lobe and the contiguous upper lobe together.
Path comment after partial lung lobectomy: In all likelihood this is a malignant process occurring in smooth muscle changes surrounding vessels within the lung versus an undifferentiated epithelial tumor.
ADDENDUM DX: low grade pulmonary sarcoma with smooth muscle differentiation.
Consultant's report concurs with that of the original pathologist's report of malignant neoplasm compatible with smooth muscle origin.
