Coexistence of primary pulmonary meningioma and metastatic papillary renal cell carcinoma of the lung: A rare case report with review of the literature

Abstract

Rationale: Primary pulmonary meningioma (PPM) is extremely rare tumor and only a few reports have been reported to date. PPM may be overlooked when it coexists with other types of tumors in the lung. It is essential to have a knowledge of the clinicopathological features of PPM and to recognize this rare coexistence.

Patient concerns: A 57-year-old male underwent surgery for papillary renal cell carcinoma, when 2 pulmonary nodules were detected using chest computed tomography.

Diagnosis: The coexistence of benign PPM and metastatic papillary renal cell carcinoma was histologically confirmed.

Interventions: A lobectomy was performed.

Outcomes: The patient recovered well after surgery and was discharged on postoperative day 4.

Lessons: Duo to the rarity of PPM, it is easily overlooked, especially when it coexists with other tumors in the lung. The possibility of PPM needs to be taken into account when diagnosing pulmonary nodules in clinical practice.
