A 72-year-old woman with rheumatoid arthritis was treated with methotrexate (MTX) and iguratimod. Upon examination of a liver tumor, blisters due to varicella-zoster virus (VZV) infection were observed. Despite oral administration of valacyclovir, she developed varicella pneumonia and meningoencephalitis. ⋯ The liver tumor shrank after discontinuance of MTX, and polymerase chain reaction revealed the reactivation of the Epstein-Barr virus (EBV). Therefore, we were unable to deny MTX-associated lymphoproliferative disorder (MTX-LPD). This is the first case of a complication of pneumonia and meningoencephalitis due to VZV reinfection and EBV reactivation.

Case Reports
Status Cataplecticus with Rapid Eye Movement Sleep Excess in Late-onset Narcolepsy Type 1.
A 57-year-old man presented with difficulty speaking and walking along with increased daytime somnolence. His symptoms fluctuated throughout the day but never completely disappeared. A neurological examination revealed mild dysarthria, limb weakness, and staggering gait. ⋯ Human leukocyte antigen testing demonstrated DQB1*0602 positivity. His neurological symptoms were relieved by clomipramine. Thus, he was diagnosed with late-onset narcolepsy type 1 with status cataplecticus.

Liver Biopsy-confirmed Primary Hepatic Amyloidosis with Only Jaundice as the Initial Symptom: An Autopsy Case Report.
Amyloidosis causes various symptoms in many organs of the body, but amyloidosis that presents with liver damage alone has never been reported. We treated an 83-year-old man with amyloidosis who presented with liver damage alone. ⋯ The administration of bortezomib and dexamethasone was not effective, so he rapidly died of liver failure. An aggressive liver biopsy should be considered when unexplained jaundice is observed.

Case Reports
A Case of Cerebral Tuberculoma with Mild Posterior Cervical Pain as the Main Symptom Despite Extensive Brain Lesions.
A 59-year-old woman with a diabetes history experienced mild neck pain. A neurological examination revealed only mild neck stiffness. Magnetic resonance imaging showed extensive T2-weighted high-intensity lesions with patchy gadolinium enhancement mainly involving the white matter in the right parietal lobe. ⋯ While QuantiFERON-TB Gold was positive, computed tomography (CT) and fluorodeoxyglucose on positron emission tomography-CT of the whole body showed no abnormal accumulation, suggesting tuberculosis. A brain biopsy revealed cerebral tuberculoma. As cerebral tuberculoma can show minimal neurological symptoms despite extensive lesions, a cautious examination and early treatment are required to prevent a devastating prognosis.

Case Reports
A Case of Severe Anemia Caused by Gastric Antral Vascular Ectasia and Autoimmune Gastritis.
An 80-year-old man presented to our hospital with general fatigue on exertion that had gradually worsened over 6 months. His blood test revealed severe anemia, and gastroscopy revealed findings consistent with gastric antral vascular ectasia (GAVE) and autoimmune gastritis. ⋯ The present case suggested that GAVE is triggered by autoimmune gastritis, and the mechanism is likely related to hypergastrinemia. The reporting of this rare case may help elucidate the cause of GAVE, which is currently unknown.
