title: Myasthenia gravis and primary squamous cell carcinoma of the thymus.
abstract: Occurrence of primary squamous cell carcinoma of the thymus gland in a 65-year-old man with myasthenia gravis is reported. Histologic and immunohistochemical studies confirmed the diagnosis of a differentiated squamous cell carcinoma. Extensive clinical investigations ruled out another primary site for the tumor. The patient made a full recovery postoperatively. Only three cases of primary squamous cell carcinoma of the thymus gland in association with myasthenia gravis have been reported in the literature.
