A case of primary plasma cell tumour of the trachea is reported in a man with extensive bilateral bronchiectasis, chronic bronchitis and emphysema. The tracheal lesion was multiple, but there was no evidence either of metastatic spread to the regional lymphatic glands or of diffuse myeloma.
The literature on extra-medullary plasma cell tumours is briefly reviewed with special reference to tracheal involvement.
85· per cent. of 446 patients who had thoracoplasty are satisfactory 1 to 7 years later. Another 4·3 per cent., now lost sight of, were well when last seen.
Such good results are unlikely in the future, if thoracoplasty is to be used mainly in cases unsuitable for resection.
The average age of tuberculous patients is increasing. Chemotherapy is prone to fail in older people and, where long-term chemotherapy has not converted the sputum, thoracoplasty is only moderately successful: it is wrong to expect brilliant results among salvage cases.
These operations were carried out by Mr. M. Hickey, Mr. B. O'Neill, Mr. D. Kneafsey, Mr. H. Wingfield, Mr. K. Shaw.
The bronchial tree is, within the lung, an independent organ. It serves primarily to conduct and moisten air passing to the respiratory tissue. The folds of the bronchial mucous membrane are a normal feature; they improve the function of the mucous membrane.
A case of pulmonary embolism in a young man is described.
The high incidence of this condition in his family is discussed.
