Case Reports
Malignant Melanoma Metastasis to the Appendix as the First Presentation of Lentigo Maligna Melanoma.
Malignant melanoma is a malignant neoplasm of the skin and mucosal tissues, and its behavior is not predictable. Thus, it could metastasize via mysterious routes. Here, we report a rare case of acute abdomen and acute appendicitis which involved metastatic malignant melanoma in a 63-year-old man without a history of previously treated malignant melanoma.

Case Reports
Acute Myocardial Infarction and COVID-19 in a Known Case of Granulomatosis with Polyangiitis.
Since the emergence of novel coronavirus and the disease named as COVID-19 in late December of 2019 in Wuhan, Hubei province, China, many aspects of this disease have been reported in the literature (mainly pulmonary manifestations). In patients with COVID-19, rheumatic and cardiovascular manifestations and interactions were reported separately, but they were all very rare. ⋯ Post COVID-19 infection, she developed exacerbation of her disease. Besides the rheumatologic manifestations, she developed epigastric pain found to be acute myocardial infarction (MI) that needed primary percutaneous coronary intervention (PCI).

The clinical significance of gastrointestinal wall thickening (GWT) on abdominal computed tomography (CT) is not certain, yet. Despite the need for clinical guidelines describing the importance and evaluation of GWT on a CT scan, there have been few studies evaluating these incidental imaging abnormalities. The aim of this study is to endoscopically evaluate certain etiologies that cause incidental GWT found on CT. ⋯ In this study, detection of GWT on CT often indicated pathologies which were subsequently confirmed endoscopically. Pathological findings were detected in 83% of these patients, with approximately 30% determined to be malignant. Endoscopic evaluation is recommended when GWT is reported on a CT scan.
