A 43-year-old man was admitted to our hospital because of diplopia, ptosis, and dysphagia that had begun three years previously. He was diagnosed with myasthenia gravis (MG) and invasive thymoma and treated with corticosteroid, thymectomy, and radiation therapy. Ten years after the thymectomy, computed tomography (CT) showed metastasis of the thymoma in the left lower lobe of the lung. Two years after this recurrence, when the patient was 55, respiratory symptoms such as wheezing, persistent cough, and dyspnea appeared. Chronic sinusitis, diffuse centrilobular opacities on CT, and positivity for HLA-B54 led to a diagnosis of diffuse panbronchiolitis (DPB). Despite treatment with clarithromycin, the respiratory symptoms worsened. The patient developed alopecia and body hair loss at the age of 56 followed by dysgeusia, cholangitis, and myositis with positivity for anti-Kv1.4 antibodies. Although treatment with an increased dose of corticosteroid improved hair loss, dysgeusia, cholangitis, and myositis, he died of progression of DPB and serious respiratory infection at the age of 58. In this case, various autoimmune disorders occurred together with MG as complications of thymoma. Although alopecia, dysgeusia, and myositis are already known as complications of MG associated with thymoma, cholangitis is not well-recognized since there have been few reports suggesting a causal relationship between cholangitis and thymoma. Furthermore, DPB caused by immunodeficiency and respiratory tract hypersensitivity associated with thymoma and HLA-B54, respectively, is the distinctive feature of our case. Neurologists should be aware that various organs can be damaged directly and indirectly by abnormal T cells from thymoma in patients with MG.

A 66-year-old woman who had myasthenia gravis (MG) admitted for type II respiratory failure and right heart failure. Although she had neither ptosis, eye movement disorder, nor diplopia, she had orbital muscles weakness, reduction of gag reflex, dysarthria, dysphagia, and mild proximal muscle weakness. Blood tests showed anti-striated muscle antibodies (anti-titin antibody and anti-Kv1.4 antibody). A muscle biopsy of the left biceps showed a marked variation in fiber size, mild mononuclear cell infiltration was seen surrounding blood vessels in perimysium and nemaline bodies in some fibers. Immunohistochemical stains showed many muscle fibers express HLA-ABC. The patient was diagnosed as sporadic late-onset nemaline myopathy (SLONM) with MG, and treated by tacrolimus. After treatment, her respiratory function gradually improved and she discharged. In the case of atypical MG, measurement of anti-striated muscle antibody or muscle biopsy should be considered.
