Pyogenic granulomas are a benign vascular tumor of the skin and mucous membranes commonly affecting the oral cavity, and less commonly the nasal cavity. Their etiology is unknown, however, pyogenic granulomas have been closely related to pregnancy. We report herein on a 31-year-old pregnant woman with a rapidly growing hemorrhagic lesion within the nasal cavity, which required pre-operative embolization and subsequent endonasal excision under general anesthesia after delivery of a child. In this report, we discuss the clinical figures, radiological and histological characteristics of pyogenic granulomas, and their treatment strategy.
