ABSTRACT: Pulmonary hyalinising granuloma (PHG) is a rare fibrosclerosing inflammatory lung condition of unknown aetiology. It is characterised by solitary or multiple pulmonary nodules that are usually found incidentally while imaging the chest for other reasons. We report two cases of histologically proven PHG diagnosed at the Royal Hospital, Muscat, Oman. The first case was a 71-year-old male patient who presented in 2010 with a dry cough, weight loss and bilateral pulmonary nodules. The second case was a 58-year-old male patient who presented in 2012 and was found to have incidental bilateral pulmonary nodules on chest X-ray. Both patients were started on prednisolone and on follow-up the PHG nodules remained stable. Although there is no definitive treatment, PHG generally has an excellent prognosis.
