A 71-year-old woman was admitted for further examination of an increased serum LDH level. Abdominal ultrasonography and CT scan showed a large tumor in her spleen. Because malignant lymphoma was ...suspected, the spleen was removed for diagnosis and treatment planning. The histopathological and immunohistochemical features of the tumor indicated diffuse large B-cell lymphoma (DLBL). The flow-cytometric immunophenotype of the lymphoma cells was CD2-, CD3-, CD4-, CD5-, CD8+, CD10+, CD19+, CD20+, CD23-, kappa+, lambda-, CD25+, and CD56-. From these findings, the patient was diagnosed as having CD8+ DLBL. To our knowledge, this is the first reported case of primary splenic CD8-positive DLBL.
Four male patients and one female patient of a new family with Joseph disease are reported. Their disease was characterized by autosomal dominant inheritance, bulging eyes, rigidity and spasticity of ...the lower extremities, dystonia, and bradykinesia. Cerebrospinal fluid homovanillic acid level was markedly reduced. Levodopa improved dystonia. Magnetic resonance imaging revealed mild atrophy of the frontal lobe and the cerebellum and marked atrophy of the lenticular nucleus and the brain stem. Polysomnographic studies revealed non-rapid eye movement stage central type sleep apnea syndrome. This is the first report using magnetic resonance imaging and sleep apnea studies of Joseph disease.
