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.

Case Reports
A Case of Lenvatinib-induced Interstitial Pneumonia in a Patient with Hepatocellular Carcinoma.
Lenvatinib is a multi-targeted tyrosine kinase inhibitor available for the treatment of unresectable hepatocellular carcinoma (HCC). We herein report an 84-year-old-man with interstitial pneumonia caused by lenvatinib. ⋯ However, he continued to take lenvatinib for four more months until he complained of dyspnea on exertion. This is a case of lenvatinib-induced interstitial pneumonia that progressed relatively slowly with a long asymptomatic period despite the appearance of pneumonia on image findings.

Pancreatic colloid carcinoma, also known as mucinous non-cystic carcinoma, is a rare subtype of pancreatic cancer accounting for 1-3% of the pancreatic malignant neoplasms. We herein report a woman who initially presented for acute pancreatitis. ⋯ The patient was diagnosed with pancreatic colloid carcinoma, and distal pancreatectomy was performed. This case indicates that pancreatic colloid carcinoma should be considered as a differential diagnosis of pancreatic tumor presenting with acute pancreatitis.

A 92-year-old woman diagnosed with dementia and end-stage gastric cancer received end-of-life care on the island where she lived. Informed consent concerning remote death certification based on the Japanese government's guidelines was obtained from a family member in case a physician was unavailable. ⋯ Death certification was provided accordingly. To our knowledge, this was the first case of remote death certification using telemedicine in Japan.

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.
