## TL;DR

This paper presents a rare case of recurrent thymic carcinoma appearing as a large diaphragmatic mass, emphasizing the need for multidisciplinary care in managing aggressive, locally invasive tumors.

## Contribution

The novelty lies in highlighting a rare presentation of thymic carcinoma recurrence with no distant metastasis, emphasizing multidisciplinary management for favorable outcomes.

## Key findings

- A 20 cm thoracic mass was identified as a recurrence of thymic carcinoma with no distant spread.
- The patient remained disease-free after one year of multidisciplinary treatment.

## Abstract

Thymic carcinoma is a rare and aggressive tumor of the anterior mediastinum, known for its varied presentations and unpredictable behavior. We report a case of a gentleman in his fifties, with a prior history of thymic carcinoma, who presented with a large thoracic mass measuring nearly 20 cm, suggestive of a recurrence, yet remarkably with no evidence of distant spread. He was managed through a multidisciplinary approach and remains disease-free at the end of one year. This case highlights the locally invasive nature of thymic tumors and underscores the importance of comprehensive, team-based management in achieving favorable outcomes in such rare malignancies.
