Undifferentiated pleiomorphic sarcoma simultaneously occuring with thymoma
We report here a case of thymoma simultaneously associated with neuroendocrine tumor. A 65-year-old male, presented with cough. Radiographic studies showed a mediastinal mass. On fine needle aspiration cytology and histopathological examination, a diagnosis of thymoma with coexisting undifferentiated pleomorphic sarcoma was made. Although thymoma is associated with many extrathymic malignancies, its association with neuroendocrine tumor is rare. This case is being reported on to reinforce that clinicians should bear in mind the possibility of extrathymic malignancies in patients with thymoma.
