A 78-year-old Japanese man underwent routine esophagogastroduodenoscopy, during which a reddish, flat elevated lesion was observed in the middle third of the esophagus. A bright red area of protrusion appeared in the center of the elevated lesion three months later, and the protruded nodule grew to be a blood blister six months after the initial endoscopy examination. The morphology of the lesion changed from a protruded nodule to a mass with two humps that subsequently returned to a single hump during the three-year observation period. A histological diagnosis of pyogenic granuloma was made based on a biopsy performed at six months. This report illustrates a rare case of an esophageal pyogenic granuloma presenting with a unique endoscopic appearance and morphologic changes. Endoscopic ultrasonography images are also presented.
