Abstract

A 39-year-old man presented with chief complaints of epistaxis and pain on the right cheek that lasted for approximately 2 months. A very hard calcified black mass with a foreign body was found in the right inferior nasal meatus. The patient underwent endoscopic endonasal surgery and antimicrobial therapy, which included intravenous injection of Penicillin G 4 million units 6 times/day for 1 week and oral amoxicillin 1500 mg/day for 6 months. Actinomyces species was identified from the calcified foreign body that measured 5 mm in size. There was no recurrence for 1 year after the surgery. Surgical removal and long-term high-dose penicillin for 6 months or longer are necessary because death caused by poor compliance with antibiotics have been reported in previous studies.
