title: [An autopsy case of a patient with myasthenia gravis who showed various symptoms of collagen diseases and complicated with malignant thymoma].
abstract: A 37-year-old man suffered from photosensitivity and urinary casts with serological findings of positive anti-DNA antibody, LE cells and false positive VD reaction in September of 1979. He developed general fatigue, dyspnea and diplopia with ptosis of bilateral eyelids in November of 1979, which were improved by the anti-cholinesterase drugs. In January of 1980, he had an attack of unconsciousness and his chest X-ray film showed several tumorous shadows in the anterior mediastinum and middle and lower lung fields. Treating him with chemotherapy of VEMP, the pulmonary shadows disappeared. However, he developed severe muscle weakness with an elevated CPK (430 mU/ml) and a myogenic EMG pattern along with an increased anti-acetylcholine receptor antibody (243 n Mol/l), dysphagia and eyelid-ptosis. He died in September of 1985 and his autopsy disclosed a malignant thymoma of mixed type in the anterior mediastinum and an atrophy and fibrosis with infiltration of inflammatory cells in the striated muscles.
