Rationale: Pulmonary spindle cell carcinoma (PSCC) is a rare subset of pulmonary sarcomatoid carcinoma. PSCC is aggressive and has a poor prognosis. Pulmonary sclerosing pneumocytoma (PSP) is an asymptomatic slow-growing benign tumor, which usually occurs in middle-aged women. Patient concerns: Herein, we report a case of solitary PSCC, occurring concomitantly with PSP in a 74-year-old woman. The patient visited our institution with productive purulent cough, dyspnea after activity, and hemoptysis. Enhanced computed tomography revealed an inhomogeneous enhanced mass with central low-attenuation in the right upper lobe (RUL). The mass located in the right lower lobe (RLL) exhibited homogeneous enhancement. Diagnosis: These lesions were subsequently diagnosed as PSCC in the RUL and PSP in the RLL, following postoperative pathological examination. Interventions: We performed lobectomy for the RUL and wedge resection for the RLL in one procedure. Outcomes: The patient did not experience complications after surgery. No radiological evidence of recurrence was observed on follow-up computed tomography performed within 7 months after the procedure. Lessons: This case fully reflects the importance of the differential preoperative diagnosis of benign and malignant solitary pulmonary nodules. However, a rare and aggressive malignant tumor may have imaging features typical of a lung abscess, which should be treated carefully.
