Case Report: Type A invasive thymoma with renal metastasis

Area of Science:

• Oncology
• Pathology

Background:

• Thymomas, rare thymus malignancies, typically occur in the anterior mediastinum.
• While generally indolent, thymomas can metastasize to distant organs.

Observation:

• A 65-year-old male with invasive thymoma (Type A, Masaoka stage IV) presented with renal metastasis seven years post-diagnosis.
• This represents an exceedingly rare site for thymoma metastasis.

Findings:

• The patient underwent successful laparoscopic-assisted radical nephrectomy and chemotherapy.
• This multidisciplinary approach facilitated long-term survival despite advanced disease.

Implications:

• Highlights the importance of monitoring for extrathoracic metastases in thymoma patients.
• Emphasizes the need for vigilant follow-up to improve early detection and patient survival.
