Report of an esophageal pyogenic granuloma that grew rapidly in one year

A 73-year-old female patient underwent esophago-gastro-duodenoscopy (EGD) because of a sore throat. The EGD detected a prominent granulomatous lesion in the middle of the esophagus, a finding that had not appeared in an EGD performed one year earlier. The patient was referred to our hospital for detailed examination. We observed a soft, lobular, pedunculated lesion with a reddened color and white deposits. Narrow Band Imaging showed dilated blood vessels at the base of the lesion, and no malignant findings of intrapapillary capillary loop. We performed an en-bloc resection by endoscopic mucosal resection following snaring for 1 minutes to prevent bleeding. The histopathological diagnosis was an esophageal pyogenic granuloma with a covering of hyperplastic squamous epithelium, proliferation of capillaries showing a lobular structure, and infiltration of inflammatory cells. Though mostly found along the gastrointestinal tract, esophageal pyogenic granuloma is rarely reported in the literature, unlike lesions of the skin and oral cavity. In summary, we reported the case of a 73-year-old female patient with an esophageal pyogenic granuloma that grew rapidly in a short period.
