Mucinous adenocarcinoma of the thymus: report of a case

Thymic mucinous adenocarcinoma is a very rare neoplasm. This tumor has a poor prognosis and its treatment is not established. In addition, the existence of KRAS mutations of thymic mucinous adenocarcinoma is still unknown, despite these mutations are common in lung mucinous adenocarcinoma. We present the case of a 79-year-old woman with primary thymic mucinous adenocarcinoma. Therefore, we reviewed clinico-pathological features of thymic mucinous adenocarcinoma in details and analyzed KRAS gene mutations of the present case.
