Review Case Reports
Epstein-Barr Virus-positive Intestinal Diffuse Large B-cell Lymphoma in a Japanese Patient with Celiac Disease: First Reported Case and a Literature Review.
A 60-year-old Japanese woman was diagnosed with celiac disease (CeD) and treated with a gluten-free diet. For five years, she had a good clinical course. However, she complained of inappetence and nausea. ⋯ Immunohistologically, the atypical lymphoid cells were positive for cluster of differentiation (CD) 10 and CD20. Many Epstein-Barr virus-encoded small RNA (EBER)-positive atypical lymphocytes were detected by in situ hybridization. This represents the first reported case of Epstein-Barr virus-positive intestinal diffuse large B-cell lymphoma complicated with CeD.

Review Case Reports
A Rare Case of Ulcerative Colitis with Severe Pneumocystis jirovecii Pneumonia and Cytomegalovirus Colitis: A Case Report and Literature Review.
Pneumocystis jirovecii pneumonia (PJP) and cytomegalovirus (CMV) colitis are opportunistic infections that occur during immunosuppressive treatments for ulcerative colitis (UC). The prognosis of PJP and CMV colitis is very poor. ⋯ Furthermore, a literature review of similar cases suggested that prophylactic therapy for opportunistic infections might be important, especially in the elderly. This case will serve as a reference for successful treatment in future cases.

Congenital afibrinogenemia is a rare autosomal recessive blood disorder that accompanies thrombotic complications and is associated with bleeding tendency. The management of these opposing complications remains a challenge. ⋯ The cause of the pain was confirmed to be renal infarction and lower extremity arterial thrombosis by Doppler ultrasound and contrast-enhanced computed tomography. He was treated with EVT for the lower extremity arterial thrombosis, leading to an excellent short-term improvement without bleeding.

Case Reports
Thymic Adenocarcinoma with Positivity for Thyroid Transcription Factor-1 and a BRAF V600E Mutation: A Case Report.
Thymic adenocarcinomas are rare. We herein report for the first time a case of thymic adenocarcinoma with positivity for thyroid transcription factor-1 (TTF-1) and a BRAF V600E mutation. A 50-year-old woman had persistent suffocation and chest pain. ⋯ Immunohistochemically, the tumor was positive for TTF-1. A sequencing analysis revealed a BRAF V600E mutation. The patient underwent postoperative radiotherapy and was in good health without recurrence at five months after resection.

A 77-year-old man complained of postmeal vomiting and sustained general fatigue. An abdominal computed tomography scan showed massive gastric expansion and fluid storage. ⋯ On the fourth day, we performed endoscopic crushing and removal by injecting Coca-Cola®, cutting the softened bezoar with endoscopic snares, and collecting the pieces with endoscopic nets. We herein report (with a video presentation) a rare case of tannin-phytobezoars endoscopically removed with the administration and injection of Coca-Cola®.
