Summary
This report details a rare case of a giant thymoma, a type of thymus cancer, found in the anterior mediastinum. Surgical resection was successful, with pathological diagnosis confirming a type AB thymoma, Masaoka stage IIB.
Area of Science:
- Thoracic oncology
- Surgical pathology
- Diagnostic imaging
Background:
- Thymoma, an epithelial neoplasm of the thymus, frequently occurs in the anterior mediastinum.
- It accounts for a significant portion (20-30%) of adult mediastinal tumors.
Observation:
- A case of a giant thymoma (19 cm × 16 cm × 15 cm) in the anterior-inferior mediastinum is presented.
- The patient, a 46-year-old male, experienced mild chest pain and shortness of breath.
- The tumor was found to be adherent to the left upper lobe of the lung and surrounding pleura.
Findings:
- Complete surgical resection of the giant thymoma was achieved, along with partial resection of the left upper lobe of the lung.
- The resected tumor weighed 2,135 g.
- Pathological analysis confirmed WHO type AB thymoma, classified as Masaoka stage IIB.
Implications:
- This case highlights the possibility of exceptionally large thymomas requiring complex surgical intervention.
- Successful complete resection of giant thymomas can be achieved, offering a positive prognosis.
- Accurate pathological classification and staging are crucial for guiding treatment and predicting outcomes in thymoma patients.
