Review Case Reports
Fatal Disseminated Tuberculosis and Concurrent Disseminated Cryptococcosis in a Ruxolitinib-treated Patient with Primary Myelofibrosis: A Case Report and Literature Review.
Ruxolitinib, a Janus kinase inhibitor, improves symptoms in patients with myelofibrosis. However, its association with the development of opportunistic infections has been a concern. ⋯ This is the first case of disseminated tuberculosis and concurrent disseminated cryptococcosis during treatment with ruxolitinib. We therefore suggest considering not only disseminated tuberculosis but also cryptococcosis in the differential diagnosis of patients with abnormal pulmonary shadows during ruxolitinib treatment.

Review Case Reports
SARS-CoV-2-related Myelin Oligodendrocyte Glycoprotein Antibody-associated Disease: A Case Report and Literature Review.
We herein report a case of myelin oligodendrocyte glycoprotein (MOG) antibody-associated disease after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. A 24-year-old woman developed unilateral optic neuritis 3 weeks after contracting coronavirus disease 2019 (COVID-19), followed by intracranial demyelinating lesions and myelitis. Since serum anti-MOG antibody was positive, we diagnosed MOG antibody-associated disease. ⋯ This is a suggestive case, as there are no reports of MOG antibody-associated disease with multiple neurological lesions occurring after COVID-19. The response to immunotherapy was favorable. This case suggests that it is important to measure anti-MOG antibodies in patients who develop inflammatory neurological disease after COVID-19.

Review Case Reports
Acute Coronary Syndrome Developed in a 17-year-old boy with Sitosterolemia Comorbid with Takayasu Arteritis: A Rare Case Report and Review of the Literature.
A 17-year-old boy with acute coronary syndrome was admitted to our hospital. He had xanthomas over his elbow and Achilles tendon and a high level of low-density lipoprotein cholesterol; therefore, his initial diagnosis was familial hypercholesterolemia. ⋯ Furthermore, a persistently high C-reactive protein level and images of large arteries led to a diagnosis of Takayasu arteritis. To our knowledge, this is the first case of sitosterolemia complicated by Takayasu arteritis.

Sarocladium kiliense is ubiquitous in the human environment and is an emerging opportunistic pathogen, especially among immunocompromised hosts. A 77-year-old man diagnosed with aplastic anemia suffered from non-valvular endocarditis. ⋯ This is the first case report of non-valvular fungal endocarditis caused by S. kiliense identified by PCR and a DNA sequence analysis in an immunocompromised patient. Although rare, invasive fungal infection caused by S. kiliense should be considered in immunocompromised hosts.

A 51-year-old woman was admitted because of hypercalcemia. Neck ultrasonography and computed tomography revealed the presence of parathyroid cysts on both sides. After primary hyperparathyroidism was diagnosed by technetium-99m-methoxyisobutylisonitrile scintigraphy, the patient was successfully treated with total parathyroidectomy and autotransplantation. ⋯ Given these clinical features and her family history, multiple endocrine neoplasia type 1 (MEN1) was suspected, and germline DNA sequencing revealed a missense mutation (c.1013T>C, [corrected] p. Leu338Pro) in exon 7 of MEN1. This case demonstrates the phenotypic and genetic diversity of MEN1.
