Pyogenic granuloma is a benign tumor of the dermis and mucosa. This disease is often seen in the oral and nasal cavity, however, it is rare in the hypopharynx.We report a case of pyogenic granuloma in the hypopharynx.An 84-year-old male with pharyngeal pain and hemoptysis was referred to our hospital. Laryngoscopy showed a mass located at the left side of the hypopharynx. This mass was dark red and had a stem. It moved up and down in accordance with breathing. Tracheostomy was performed under local anesthesia and the mass was removed under general anesthesia with a YAG laser using a laryngomicrosurgery technique. The histological findings showed pyogenic granuloma. Ulcerous and erosive lesions were observed on the surface of the specimen and candida-like fungus and bacteria were recognized. We considered that infection played an important role in the presence of the pyogenic granuloma in the present case.The features of pyogenic granuloma were reviewed.
