She presented with dysphagia. Upper gastrointestinal (GI) endoscopy showed a polypoid growth, and its biopsy confirmed the diagnosis. Meanwhile, she presented again with hematemesis. A repeat endoscopy showed that the previously seen lesion had likely broken off, leaving behind a residual stalk. This was snared and removed. The patient remained asymptomatic, and a follow-up upper GI endoscopy at six months did not show any recurrence.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Practical Implications<\/jats:title>\n                    <jats:p>To the best of our knowledge, this is the first case of ESP in a patient with two concurrent malignancies.
