A middle-aged Japanese man presented with slowly progressive asymmetric weakness of legs and arm but had neither ptosis nor dysphagia. He had a family history of similar condition suggestive of autosomal dominant inheritance. A muscle biopsy showed mixture of neurogenic atrophy and myopathy with rimmed vacuoles. Furthermore we found intranuclear inclusions that had a fine structure mimicking that of inclusions reported in oculopharyngeal muscular dystrophy (OPMD). Immunohistochemical staining for polyadenylate-binding nuclear protein 1, which is identified within the nuclear inclusions of OPMD, demonstrated nuclear positivity in this case. However, OPMD was thought unlikely based on the clinical features and results of genetic analyses. Instead, a novel mutation in valosin-containing protein, c.376A>T (p.Ile126Phe), was revealed. A diagnosis of inclusion body myopathy associated with Paget disease of bone and frontotemporal dementia was made. This is the first report of polyadenylate-binding nuclear protein 1-positive nuclear inclusions in the muscle of this condition.
