Abstract
Pulmonary hyalinising granuloma is a very rare disease often presenting as multiple smooth rounded nodules within the lung parenchyma and mimicking metastatic disease. Solitary pulmonary hyalinising granuloma is an even rarer subgroup, and to our knowledge, there have been no endoluminal pulmonary hyalinising granulomas reported. A 36-year-old female non-smoker with no significant past medical history presented with a persistent cough and was found to have a right lower lobe bronchial lesion causing lower lobe obstruction. After multiple failed attempts at tissue diagnosis from both percutaneous and endobronchial biopsies, and with worsening haemoptysis, the patient underwent a right thoracotomy and lower bilobectomy. The histopathology was reported as a solitary endobronchial pulmonary hyalinising granuloma. Although benign in nature, tissue diagnosis can be difficult in these lesions, especially when presenting as a solitary mass in a central location. This report demonstrates that these lesions can also be found endobronchially necessitating parenchymal resection for diagnosis and obstructive symptoms.
