Acute esophageal necrosis (AEN) is a rare endoscopic finding associated with ischemic compromise of the distal esophagus. This finding can be seen in critically ill patients with COVID-19 infection. We present a case of a COVID-19-vaccinated elderly male with multiple comorbidities and active COVID-19 pneumonia admitted to the intensive care unit with septic shock and acute hypoxemic respiratory failure. The patient developed melena, and esophagogastroduodenoscopy (EGD) was performed, which showed necrosis of the lower esophagus suggestive of AEN. AEN has been associated with high mortality and should be considered when evaluating upper gastrointestinal bleed in a critically ill patient. This case describes the first report of isolated AEN in a patient fully vaccinated against COVID-19 presenting with a severe complicated COVID-19 infection.

Background: To describe the clinical presentation, treatment, and overall prognosis in eight patients with primary Ewing's sarcoma (ES) involving the orbit. Methods: A retrospective interventional study of all biopsy-proven cases of primary ES involving the orbit was done. Results: There were seven males and one female with a median age of 14 years. Imaging showed osseous involvement in all eight cases with extraorbital extension in four. Complete tumor resection was done in four, partial resection in three, and biopsy followed by sinus surgery in one. EWSR1 gene rearrangement analysis was done to confirm diagnosis. All patients received multidrug systemic chemotherapy and seven patients received adjuvant radiotherapy. Eye salvage was achieved in all patients. At a mean follow-up duration of 52.63 months, seven patients were doing well with no evidence of disease.Conclusions: ES involving the orbit is sensitive to chemotherapy and radiation. Aggressive multimodality treatment can help salvage the globe and improve overall survival.
