A man from Saudi Arabia who suffered from regular nosebleeds was recently found to have an extra tooth growing in his nose – a rare but not unheard of medical phenomenon.

The 22-year-old reportedly experienced nosebleeds multiple times a month for years before he went to doctors, according to a report published by the American Journal of Case Reports and the Blaze. After it was discovered, the man had the growth surgically removed.

Doctors discovered an “ivory white nasal mass” in the man’s left nasal cavity. According to the report, it was causing bleeding when it was examined.

“It’s an unusual case of an extra tooth – certainly, the most impressive intranasal photo I think I’ve ever seen of one. I’ve never seen the tooth actually in there,”  said Dr. John Hellstein, a dentist in Iowa, according to Live Science.

Other studies have also reported cases of teeth growing in people’s noses. More than a decade ago, the American Journal of Neuroradiology published a study that included reports on three cases where teeth had grown in noses.

The unusual growths affect less than 1 percent of the population, according to the report. The growths could be caused by “trauma, infection, anatomical malformations and genetic factors.”
