[Plasma cell granuloma of the lung]

Plasma cell granuloma is a rare, benign and usually solitary round tumour of the lung. Although uncommon, it is found relatively more frequently among children and adolescents. The lack of symptoms and absence of characteristic features make diagnosis difficult. In adults, the differentiation from bronchial carcinomas is particularly difficult because of their radiological similarity. Consequently, thoracotomy and excision of the tumour is the treatment of choice.
