The majority of the tumours displayed a mixed pattern on microscopic examination, and cell-nest formation was a prominent feature in sixteen. The findings are at variance with the results of a similar series reported from Japan and suggest that there is regional variation in the tumour pattern of pulmonary carcinoids. Various aspects of the histopathology are discussed, and a causal relationship between ossification of bronchial cartilage in these tumours and locally produced calcitonin is postulated.}, issn = {0021-9746}, URL = {https://jcp.bmj.com/content/32/11/1100}, eprint = {https://jcp.bmj.com/content/32/11/1100.full.pdf}, journal = {Journal of Clinical Pathology} }
