[Extensive multiple hamartomas of the lung of the diffuse juvenile type].

The case report of a 12 year-old female patient suffering from extensive multiple hamartomas of the left lung (diffuse juvenile type) is presented. The clinical features were atypical due to the large size of the tumour. The entire left lung and parts of the pleura and pericardium were involved. The diagnosis was reached only after histological examination of the operation specimen, as is usual with intrapulmonary hamartomas of the lung.
