[Plasma cell granuloma. Report of a case].

The authors report a case of plasma cell granuloma of the lung, an inflammatory tumour occurring in a young Egyptian aged 23 without any history of chest diseases. The patient had had three weeks before his hospital admission light haemoptysis and associated with weight loss. The diagnosis was made on a bronchial biopsy. Thus a diagnosis could be made without recourse to surgery because of the occurrence of bronchial invasion. No aetiological factor was found to explain the pathogenesis of the granuloma.
