Case Reports
Yellow Nail Syndrome Patients with Diffuse Panbronchiolitis-like Pulmonary Manifestation.
Yellow nail syndrome (YNS) is a rare clinical syndrome characterized by a triad of yellow thick nail, lymphedema and respiratory diseases. We experienced 2 cases of YNS with diffuse panbronchiolitis (DPB)-like pulmonary manifestation. Since YNS might be hidden to those who have been diagnosed with DPB, physicians should be alert to recognize nail signs of YNS in case of DPB refractory to macrolide therapy. We hereby review previous case reports of YNS and discuss its pulmonary manifestations.

Case Reports
Fatal Chronic Active Epstein-Barr Virus Infection in a Rheumatoid Arthritis Patient Treated with Abatacept.
Chronic active Epstein-Barr virus (CAEBV) T-cell type infection, systemic form, is characterized by persistent infectious mononucleosis-like symptoms, high Epstein-Barr virus (EBV) DNA levels in the peripheral blood, organ damage, and a poor prognosis. The association between CAEBV and rheumatoid arthritis (RA) is unclear. ⋯ CAEBV can rapidly worsen in RA patients receiving ABT. Thus, we should try to establish an early diagnosis in patients with CAEBV infection.

Review Case Reports
Pulmonary Mycobacterium abscessus Infection with Reactive AA Amyloidosis: A Case Report and Brief Review of the Literature.
We herein report a case involving a 64-year-old Japanese woman with a pulmonary Mycobacterium abscessus infection complicated by reactive AA amyloidosis, which, to our knowledge, has not been reported to date. The patient underwent gastrointestinal endoscopy for diarrhea during the treatment of pulmonary M. abscessus infection and was diagnosed with AA amyloidosis according to the histopathological findings from the endoscopic specimen. She died four months later. The prognosis of AA amyloidosis associated with pulmonary M. abscessus infection may be very poor, and physicians should pay attention to this rare condition when difficult-to-treat diarrhea occurs in patients with pulmonary M. abscessus infection.

Midventricular obstructive hypertrophic cardiomyopathy (MVOHCM) is a rare form of hypertrophic cardiomyopathy (HCM). An 80-year-old man was administered bisoprolol and warfarin therapies as treatment for MVOHCM with an apex aneurysm due to myocardial damage and intra-aneurysmal thrombus not complicated by atrial fibrillation. The pressure gradient in the midventricle successfully improved from 53.9 to 21.8 mmHg, and the intra-aneurysmal thrombus disappeared.

Fanconi anemia (FA) is a disorder of chromosomal fragility characterized by progression to aplastic anemia, myelodysplastic syndrome, and leukemia. FA patients are also predisposed to solid cancers. A case of FA in an adult patient who developed tongue and superficial esophageal cancers following hematopoietic stem cell transplantation is reported. This case was considered significant because it is the first reported case of superficial esophageal cancer in an FA patient that was treated successfully by endoscopic submucosal resection.
