Post-tuberculosis Pneumocytoma.

Area of Science:

• Pulmonology
• Surgical Oncology
• Pathology

Background:

• Pneumocytoma is a rare, benign lung tumor often presenting as a solitary pulmonary nodule.
• This case involves a 69-year-old female with a history of tuberculosis treatment.

Observation:

• A round mass was detected on chest radiography and confirmed as a lesion on thoracic computed tomography.
• Diagnostic procedures including fiberoptic bronchoscopy, CT-guided fine-needle aspiration cytology, and intraoperative frozen section were inconclusive.

Findings:

• Wedge resection via minithoracotomy was performed.
• Pathologic examination definitively diagnosed the lesion as pneumocytoma.
• The patient received no adjuvant chemotherapy or radiotherapy.

Implications:

• This case highlights the diagnostic challenges of pneumocytoma, especially when initial investigations are inconclusive.
• Surgical resection proved effective, with no recurrence noted during a 41-month follow-up period.
• Emphasizes the importance of surgical pathology for definitive diagnosis and management of suspected lung neoplasms.
