Abstract
Carcinoid tumour is a well-known primary endobronchial lung neoplasm. Although calcifications may be seen in up to 30% of pulmonary carcinoid tumours, near complete ossification of these tumours is an unusual finding. Such lesions can prove diagnostically challenging at the time of intraoperative frozen section as the latter technique requires thin sectioning of the lesion for microscopic assessment. We present an unusual case of endobronchial carcinoid tumour with extensive ossification in a 45-year-old male. Preliminary intraoperative diagnosis was achieved through the alternative use of cytology scrape smears. The final diagnosis was confirmed after decalcification of the tumour. The prognostic implications of heavily ossified carcinoid tumours remain elusive. Long-term clinical follow-up of these patients is recommended.

Summary
Endobronchial Carcinoid Tumour with Extensive Ossification: An Unusual Case Presentation. Calcifications may be seen in up to 30% of pulmonary carcinoid tumours, near complete ossification of these tumours is an unusual finding Such lesions can prove diagnostically challenging at the time of intraoperative frozen section as the latter technique requires thin sectioning of the lesion for microscopic assessment. We present an unusual case of endobronchial carcinoid tumour with extensive ossification in a 45year-old male. The patient’s past medical history was unremarkable apart from a previous 20 pack-year smoking history He reported a single episode of hemoptysis 8 years priorly and was lost to follow-up after initial radiologic investigations identified a 3.1 cm mass. Intraoperative gross specimen assessment revealed a hard, well-circumscribed, ossified 5.0 cm mass (Figure 1(c)) encasing the bronchial resection margin. A shave section of the bronchial resection margin was negative for
