Good syndrome with thymic adenosquamous carcinoma--report of a case.

Good syndrome is classified as a large entity, immunodeficiency with thymoma, not thymic carcinoma. On the other hand, thymoma and thymic carcinoma represent different points within a spectrum of differentiation and are histogenetically closely related entities. We report on a case of Good syndrome with adenosquamous thymic carcinoma, and with a small area of thymoma. Complete surgical excision and detailed pathological examination should be performed as the treatment for thymic tumors to find invasive or malignant potential.
