A 69-year-old man was admitted to our hospital because of a sudden gait disturbance. Based on the neurological examination performed upon admission, the patient exhibited ataxic movement in his right lower limb and body lateropulsion toward the right side. ⋯ A motion analysis revealed ipsilateral lower-limb ataxia. Lower lateral medullary infarction can cause ipsilateral lower limb ataxia, particularly impaired hip joint coordination, resulting in body lateropulsion in dynamic conditions.

Acquired pure red cell aplasia (PRCA), caused by thymic hyperplasia, is extremely rare. We herein report a previously healthy 41-year-old man who presented with severe anemia, lymphadenopathy, an upper mediastinal mass, and hypogammaglobulinemia. ⋯ Although his anemia improved rapidly after thymectomy, PRCA recurred approximately 500 days later and was accompanied by ATLL exacerbation. The findings in this patient suggest that the Good's syndrome-like symptoms (thymic hyperplasia and hypogammaglobulinemia) in this patient and PRCA may have been paraneoplastic syndromes caused by ATLL.

Nephrotic syndrome (NS) predisposes patients to immunocompromised hosts owing to the loss of immunoglobulins, immunosuppressant use, and edema complications. In addition, aging impairs the immune system; thus, elderly individuals with NS are vulnerable to infection. ⋯ Protecting the skin and wounds from direct exposure to nocardia is important. Physicians should consider the safe dose and treatment period of immunosuppressants in elderly patients with NS.

A 78-year-old man was diagnosed with advanced poorly differentiated gastric adenocarcinoma, presenting with jaundice and diffuse thickening of the extrahepatic bile duct. No obstructive biliary sites or liver masses were observed. ⋯ The patient was diagnosed with lymphangiosis carcinomatosa of the liver and extrahepatic bile duct but died 28 days after hospitalization. As the disease progresses rapidly with uncharacteristic imaging findings, biopsy samples should be obtained early using several diagnostic tools.
