Abstract

Pyogenic granuloma (PG) is one of the benign non-epithelial tumors derived from connective tissues on skin and mucosa. We had a case of PG, initially which was strongly suspected of malignant tumor. A 71 year-old male was referred to our clinic with chief complain of left upper gingival tumor, which had grown from the extraction socket of left upper third molar. The tumor rapidly grew again after CO₂ laser irradiation. However, the tumor disappeared spontaneously during the observation period, after the resection of a sigmoid colon cancer, which was found simultaneously with the imaging examination.
