Overview

Other diagnostic studies for thymic carcinoma include immunohistochemistry. For squamous cell carcinoma subtype, the epithelial cells are immunoreactive to CD5, CD70, and CD117. In contrast with thymomas that are negative to CD5. However, for squamous cell carcinomas of other locations, the CD5 and CD70 are negative, which means that this technique is useful to confirm the thymic origin of the tumor.
