Unknown foreign body - Lung transplant - Granuloma
This foreign material came from a follow-up transbronchial biopsy of a lung transplant. It is located in the interstitium adjacent to the airway. It is an exogenous material with the capacity to induce a giant cell foreign body reaction. It has not been identified, but it has been suggested to be plant or synthetic material used in previous surgery, as well as hydrophilic polymeric material. Right image -polarized.
