Case Reports
Listeria monocytogenes Bacteremia During Isatuximab Therapy in a Patient with Multiple Myeloma.
An elderly patient with multiple myeloma (MM) was being treated with several regimens and developed a severe drug eruption, necessitating the use of atovaquone instead of trimethoprim-sulfamethoxazole for pneumocystis pneumonia (PCP) prophylaxis. For progressive MM, treatment with isatuximab, an anti-CD38 monoclonal antibody, was started. ⋯ CD38 is closely related to the innate immune response against L. monocytogenes, and isatuximab may increase the risk of infection. Therefore, trimethoprim-sulfamethoxazole may be useful in the prevention of not only PCP but also L. monocytogenes infection.

Review Case Reports
Vimentin-positive and Alpha-fetoprotein-elevated Nuclear Protein of the Testis Midline Carcinoma: A Case Report and Review of the Literature.
Nuclear protein of the testis (NUT) midline carcinoma (NMC) is a rare malignant tumor expressing NUT with BRD4/3 rearrangements and is sometimes misdiagnosed as germinoma, especially in alpha-fetoprotein (AFP)-elevated cases. A 28-year-old man had a mediastinal tumor with multiple bone metastases and elevated AFP levels. Imaging/laboratory findings led to a pathological diagnosis of extragonadal germinoma. ⋯ A posthumous examination clarified the NUT rearrangement. Even in cases with characteristic findings, such as elevated AFP levels and vimentin positivity, NMC should be considered as a differential diagnosis. We note, however, that adriamycin-ifosfamide has some efficacy in such cases.

Objective Recent studies have found higher rates of autoimmune diseases, such as celiac disease, Crohn's disease, and ulcerative colitis, in patients with eosinophilic esophagitis (EoE) than in the general population. This study investigated the concomitant rate of autoimmune disease among Japanese patients with EoE and evaluated the clinicopathological characteristics of EoE patients with autoimmune disease. Methods The medical records of patients diagnosed with EoE between April 1, 2016, and June 30, 2020, were reviewed. ⋯ No complications, including stenosis, were seen in EoE with autoimmune disease, and most patients with EoE and autoimmune diseases were responsive to proton pump inhibitors (PPIs). Conclusion In this study, 8 out of 64 patients with EoE had an autoimmune-related disease, including ulcerative colitis (n=1, 1.6%), autoimmune polyendocrine syndrome type 2 (n=1, 1.6%), or endometriosis (n=6, 44.4% of women of reproductive age), which is higher than that previously reported in the general population. Further investigations are required to clarify the relationship between EoE and autoimmune diseases.

Case Reports
A Case of Yellow Nail Syndrome in Which Intranodal Lymphangiography Contributed to the Diagnosis.
Yellow nail syndrome (YNS) is a rare disease comprising the clinical triad of yellow nail discoloration, pleural effusion, and lower limb lymphedema. We encountered a difficult-to-treat case of YNS in which the diagnosis was finally made based on intranodal lymphangiography. An 84-year-old man was admitted to our hospital with pleural effusion and yellow-green discoloration of the nails, accompanied by onychomycosis and limb lymphedema. Intranodal lymphangiography revealed a slow contrast flow and narrowing of the thoracic duct, suggesting lymphatic duct dysplasia and leading to the diagnosis of YNS.
