Spontaneous Partial Expectoration of an Endobronchial Carcinoid

Spontaneous Expectoration of Tumor Tissue in a Patient With Adenocarcinoma of the Lung

“…9,16,17,21 As seen in our case, tumor expectoration might lead to pathological information and could relieve the respiratory symptoms. Histologically, adenocarcinoma accounts for a large proportion of cases in non-small-cell lung cancer worldwide; however, there has been no report of tumor expectoration in a patient with adenocarcinoma of the lung.…”

“…Kelly et al stated that physicians might ignore such specimens, presuming them to be phlegm or blood clots. 9 We should be aware that the expectorated tissue might lead to a pathological diagnosis, even in adenocarcinoma of the lung.…”

“…Endobronchial metastases from various organs are most common, although 9 primary lung cancer cases have been described, including 4 squamous cell carcinomas, 2 bronchogenic carcinoids, one small cell lung carcinoma, one large cell carcinoma, and one mixed type carcinoma. [1][2][3][4][5][6][7][8][9] Adenocarcinoma of the lung has never been reported. We describe a case of spontaneous expectoration of a piece of lung adenocarcinoma, which enabled a definitive diagnosis of a local recurrence, and led to substantial relief from dyspnea.…”

Spontaneous expectoration of lung tumour mass

“…3 Originally described by Mackenzie in 1886, 4 expectoration of large fragments of lung tumour is rare. 5 It has been described in cases of endobronchial primary lung cancer and metastases from renal cell and colon carcinomas, osteogenic sarcoma and malignant melanomas. 5 More recently in the era of AIDS, coughing up sections of tumour has been seen in patients with Kaposi's sarcoma and lymphoma.…”
