A Case of Esophageal Squamous Papilloma, an Unusual Cause of Dysphagia and Hematemesis in a Patient with Concurrent Malignancies

Abstract

Introduction: The oesophageal squamous papilloma (ESP) is a rare cause of dysphagia and hematemesis. The malignant potential of this lesion is uncertain; however, the malignant transformation and concurrent malignancies have been reported in the literature. Case description: We report a case of oesophageal squamous papilloma in a 43-year-old female who had a background diagnosis of metastatic breast cancer and liposarcoma of the left knee. 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. Practical implications: To our knowledge, this is the first case of ESP in a patient with two concurrent malignancies. Moreover, the diagnosis of ESP should also be considered when presenting with dysphagia or hematemesis.
