Unusual Intranuclear Inclusions in Malignant Fibrous Histiocytoma: Presence in Primary Tumor
1982
We describe previously unreported intranuclear inclusions in 2 cases of malignant fibrous histiocytoma. The inclusions were found in 2-10% of the tumor cells removed from the patients and in 2-10% of the cells examined in tumor tissue xenotransplanted in nude mice. By stereo electron microscopy the inclusions are closely packed undulating fibrils 18-23 nm in diameter. They are sometimes associated with fibrillary bodies. They closely resemble the inclusions reported in some animals inoculated with serum from patients with non-A non-B hepatitis; however, their nature at present is unknown.
Value of insoluble PABPN1 accumulation in the diagnosis of oculopharyngeal muscular dystrophy.
2019
Background and purpose The aim was to assess the value of insoluble PABPN1 muscle fibre nuclei accumulation in the diagnosis of atypical cases of oculopharyngeal muscular dystrophy (OPMD). Methods Muscle biopsies from a selected cohort of 423 adult patients from several Italian neuromuscular centres were analysed by immunofluorescence: 30 muscle biopsies of genetically proven OPMD, 30 biopsies from patients not affected by neuromuscular disorders, 220 from genetically undiagnosed patients presenting ptosis or swallowing disturbances, progressive lower proximal weakness and/or isolated rimmed vacuoles at muscle biopsy and 143 muscle biopsies of patients affected by other neuromuscular diseas…
