ABSTRACT

This paper reports the case of a 41 year-old man presenting with retrosternal pain and submitted to endoscopic examination. The endoscopic procedure revealed a small polypoid mass in the lower esophageal mucosa which was partially resected. Histologic examination showed that it was composed by numerous capillaries embedded in a stroma with chronic inflammatory cells. At the surface there was regenerative atypia which initially led to differential diagnosis with a malignant neoplasm. Follow-up at two months proved the presence of a remaining small protrusion which showed loose connective tissue with branching capillaries. Review of the literature revealed 6 other cases of this peculiar lesion, two combining Barrett’s esophagus. Pyogenic granuloma of the esophagus is unusual. Careful clinico-pathologic correlation must be followed when interpreting regenerative atypia. There are no reported cases depicting the histologic maturation changes as seen in the present patient.
