[Thoracic inflammatory pseudotumors : A rare differential diagnosis]

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pathology

Background:

• Inflammatory pseudotumors (IPTs) are rare, potentially infiltrative tumors.
• Complete resection is often necessary to rule out lung cancer.
• This study reviews institutional experience with IPTs.

Purpose of the Study:

• To analyze surgical outcomes for lung inflammatory pseudotumors.
• To evaluate resection extent, morbidity, mortality, and long-term results.
• To assess the diagnostic challenges of IPTs versus lung cancer.

Main Methods:

• Retrospective study of 13 patients operated on between 2002 and 2016.
• Analysis of resection extent (standard vs. extended), surgical approach (thoracotomy vs. thoracoscopy), and complications.
• Evaluation of preoperative diagnostic limitations and postoperative outcomes.

Main Results:

• 13 patients (5 female, 8 male) with a median age of 52 years underwent resection.
• 11 pulmonary, 1 tracheal, and 1 chest wall IPT were resected via thoracotomy or thoracoscopy.
• All cases achieved R0 resection with 7.7% morbidity and 0% mortality.

Conclusions:

• Preoperative diagnosis differentiating IPTs from lung cancer is challenging.
• Complete histological preparation is vital for accurate diagnosis.
• Extended resection may be required for R0 achievement, with favorable long-term results and low complication rates.
