A 7-year-old Chinese boy who had been complaining about a mysterious bad smell for two years had a metal screw stuck in his left nostril.

The unnamed boy from Jiaozuo, China’s Henan Province, had been telling his parents that he smelled something bad for at least a couple of years, but they could never figure out what it was. They certainly couldn’t smell what it was, and the 7-year-old child couldn’t really describe the smell, so for a long time, they ignored his claims as make-believe. However, his complaints became more frequent in recent weeks, so they decided to take him to a doctor. An examination of the boy’s nostrils revealed a mysterious black mass in his nose, a find later confirmed by a CT scan of his head.
