Thymomas are rare and usually slowly growing tumors, originating from the epithelial layer of the thymus. Prognosis depends on the extent of invasion of adjacent tissues whereby multimodality treatment including surgery with or without adjuvant chemoradiotherapy is the preferred approach for locally advanced thymomas. For metastatic thymomas, only few chemotherapeutic options are available. We report 2 cases of patients with metastatic thymic malignancies with a dramatic response on pemetrexed treatment. The choice for this antifolate therapy is based upon a small series. Because metastatic thymic neoplasm is a rare disease, large randomised trials are not feasible. Case reports on the treatment of these malignancies are very important and can provide readers with the opportunity to deal with rare dis- eases.
