Imaging findings
Chest CT and MRI demonstrate an anterior mediastinal mass invading local tissue, which is radiographically indistinguishable from an aggressive thymoma. Pathological resection and immunohistochemistry show a p40 and CD5 positive squamous cell carcinoma.
Key takeaways
Thymic carcinoma (most commonly squamous cell carcinoma) is a highly aggressive malignant epithelial tumor of the thymus. It is differentiated from thymoma by cytological atypia and immunohistochemical markers such as CD5 and p40 positivity.
