Review Case Reports
Duodenal Heterotopic Pancreas with a Large Retention Cyst: A Case Report and Literature Review.
A 75-year-old man was referred to our hospital with a suspected pancreatic cyst. Imaging tests revealed a 3-cm cystic lesion located ventrally in the duodenal bulbus, which was suspected to be a duplication cyst with its muscularis propria contiguous to that of the duodenum. ⋯ The diagnosis was a large, non-malignant retention cyst. Inflammation due to impaired outflow of pancreatic juice from the HP was identified as the cause of cyst enlargement.

Objectives Coronavirus disease 2019 (COVID-19) reportedly causes thromboembolic complications due to coagulopathy with hypercoagulability and a hypofibrinolytic state. We evaluated the time-course of coagulopathy in patients with severe COVID-19 from admission to discharge from our intensive-care unit (ICU). Methods We conducted a retrospective study of adults with severe COVID-19 admitted to our ICU between January 20, 2021, and March 31, 2022. ⋯ The maximum lysis at 60 minutes in the extrinsic coagulation pathway (EXTEM) and intrinsic coagulation pathway (INTEM), as markers of the fibrinolytic function, were both significantly lower at discharge than at admission [median (interquartile range), admission vs. discharge: EXTEM, 3 (2-4) vs. 1 (0-2), p=0.011; INTEM, 3 (1-6) vs. 1 (0-2), p=0.008]. Conclusion This study revealed a persistent hypercoagulable state at ICU discharge and a worse hypofibrinolytic state at discharge than at admission. These results may contribute to a better understanding of coagulopathies in the acute to subacute phases of severe COVID-19.

Case Reports
Metastatic Lung Tumors from Colorectal Cancer with EGFR Mutations That Responded to Osimertinib.
A 50-year-old woman who had previously undergone right hemicolectomy and chemotherapy for colorectal cancer was hospitalized with respiratory failure. Chest computed tomography showed reticulonodular opacities and enlarged lymph nodes. ⋯ We diagnosed her with metastatic lung tumors from colorectal cancer based on additional immunohistochemical staining and the EGFR mutation status (L861Q) of the specimens. Although cases with EGFR mutations have been rarely reported, an EGFR-TKI can be an effective treatment option for colorectal cancer.
