Summary
This study details three cases of synchronous multiple thymoma, a rare condition where patients develop multiple thymomas simultaneously. All patients underwent successful surgical removal, with no recurrence observed, highlighting effective treatment strategies for this rare thymic neoplasm.
Area of Science:
- Oncology
- Thoracic Surgery
- Pathology
Background:
- Thymoma is a rare tumor of the thymus gland.
- Synchronous multiple thymoma is an uncommon presentation.
- Myasthenia gravis (MG) is frequently associated with thymoma.
Observation:
- Three cases of synchronous multiple thymoma were diagnosed over 10 years.
- Two cases were associated with myasthenia gravis.
- Preoperative imaging (CT) and pathological examination identified multiple thymic lesions.
Findings:
- All patients underwent extended thymectomy via median sternotomy.
- Identical World Health Organization subtypes were found in each patient's multiple thymomas.
- Masaoka staging was I/I, I/I, and I/II, with uneventful postoperative courses and no recurrence.
Implications:
- This case series contributes to understanding the pathogenesis and management of synchronous multiple thymoma.
- Successful surgical resection appears to be an effective treatment.
- Further research into the etiology and optimal treatment of this rare entity is warranted.
