Abstract:
Esophageal actinomycosis is a rare type of esophageal infection, with only approximately 24 cases previously reported in the United States. Most of these cases were described as erosions or ulcers when examined endoscopically. We present a 47-year-old woman who presented with dysphagia. Endoscopy showed a lower esophageal fungating mass, mimicking a malignant mass. Although there was a high suspicion of esophageal carcinoma, biopsy results showed esophageal actinomyces infection.
