Case Reports
A Case of Autoimmune Pulmonary Alveolar Proteinosis During the Treatment of Idiopathic Inflammatory Myopathy.
Approximately 50% of idiopathic inflammatory myopathies (IIMs) are associated with interstitial lung disease (ILD). Typically, IIM-ILD manifests as nonspecific interstitial pneumonia. ⋯ We postulated that PAP may have been induced by IIM treatment with prednisolone. Our case suggests that the possibility of autoimmune PAP should be considered in patients with lung lesions during the clinical course of IIM.

Epidural Spinal Cord Compression as the Presenting Manifestation of Acute Myeloid Leukemia: A Case Report and Literature Review.
We herein report a rare case of spinal cord compression due to epidural involvement of acute myeloid leukemia (AML). A 14-year-old boy presented with a 7-day history of back pain, paraplegia and hypoesthesia. Contrast-enhanced computed tomography revealed an epidural mass. ⋯ Chemotherapy was initiated, and complete remission was achieved. Neurological sequelae remained after the treatment. Based on the present and previous reports, spinal cord compression from epidural AML involvement may progress rapidly.

Objective Pancreatic cystic lesions (PCLs) are known risk factors for pancreatic cancer. Therefore, this study explored the predictors identifying PCLs in a general population and developed a scoring system to help more efficiently diagnose these entities during medical checkups. Methods We reviewed 9,369 examinees of abdominal ultrasound (AUS) during medical checkups between January 2013 and November 2019. ⋯ The PCL detection rate increased with the total score: 0.2% for total score 0 point, 5.4% for ≥4.0 points. The area under the curve of the scoring system was 0.75 (95% CI 0.70-0.79). Conclusion Our scoring system allows the risk of PCLs to be determined and may help more efficiently diagnose these entities.

Review Case Reports
Obscure Gastrointestinal Bleeding Caused by a Small Intestinal Lymphatic-venous Malformation: A Case Report with a Literature Review.
A 44-year-old woman presented with severe anemia. We strongly suspected gastrointestinal bleeding; however, esophagogastroduodenoscopy, colonoscopy, and computed tomography showed no bleeding sources. Video capsule endoscopy revealed an actively bleeding submucosal lesion within the jejunum. ⋯ The resected specimen pathologically comprised dilated, thin-walled lymphatic channels and blood vessels involving the small intestinal submucosa. Therefore, the patient was diagnosed with small intestinal lymphatic-venous malformation. Postoperatively, the patient recovered well, and recurrence was not observed.

A 71-year-old man was admitted for left-sided chest pain. He had a history of diabetes, treatment with epidermal growth factor receptor-tyrosine kinase inhibitor for advanced non-small-cell lung cancer, and corticosteroid treatment for underlying lung diseases. ⋯ Invasive pulmonary aspergillosis was suspected, and antifungal therapy with voriconazole was initiated; however, the patient passed away suddenly. Autopsy revealed disseminated Aspergillus infection and intra-abdominal hemorrhage due to the rupture of a splenic vein aneurysm caused by Aspergillus necrotizing vasculitis, which was considered the cause of death.
