The male patient, now 50 years old, reported that throughout his childhood, he regularly played with, and swallowed, Playmobil toy pieces. On his seventh birthday, back in 1974, he received a Playmobil set, and recalled swallowing the toy cone shortly afterward.

At 46 years old, the patient consulted a doctor about a chronic cough that was concerning him.
