A handyman was suspected to have cancer after doctors found a mass in his lungs - only to discover it was a toy cone he inhaled as a child.
The 47-year-old patient, whose name is unknown, complained of coughing up yellow mucus and feeling unwell for little over a year. He sought help from doctors.
Scans showed a mass in his lungs, which consultants assumed was a sign of cancer due to him having smoked for three decades. They urgently referred him to hospital.
During a procedure to inspect his airway, medics discovered the mass to be a traffic cone from a Playmobil set, which the British man ingested 40 years ago.
Doctors writing in BMJ Case Reports have dubbed him a medical mystery, due to the length of time that passed without him displaying any symptoms.

They wrote: 'To our knowledge this is the first reported case of a tracheobronchial foreign body that was overlooked for 40 years.'
The bronchoscopy was performed at the Royal Preston Hospital after the patient was referred due to concerns the lump was a sign of bronchogenic carcinoma.
Soon after having the procedure, the patient revealed he regularly played with and even swallowed pieces of Playmobil growing up.
