RESUMEN
Neuroblastoma (NB) is an embryonal tumor of the sympathetic nervous system. It represents the most common malignant extracerebral solid tumor, and the first solid tumor in children aged less than one year. Neuroblastoma is rare in adults. We report the case of a 21-year-old male patient. Diagnosis of neuroblastoma was confirmed by percutanous CT scanner biopsy. Radiological assessment of the extension concluded to a stage IV NB with multifocal bone disease. The patient received chemotherapy based on cisplatin-etoposide (6 cycles) and a mediastinal radiotherapy. The evolution was marked by the progression of bone metastasis and the emergence of a tissular process sheathing the left optic nerve and the terminal portion of the internal carotid artery. Second line chemotherapy was indicated. A thoracic localization of NB is rare. Treatment is not codified and the prognosis is variable.

Respiratory toxicity of cannabis is well-known today particularly with the new consumption patterns. We report the case of a 25-year-old man admitted for haemoptysis, with unfavourable outcome and acute respiratory failure. Various explorations concluded to acute respiratory distress syndrome secondary to diffuse alveolar haemorrhage. Etiological assessment was initially negative. Outcome was favourable during hospitalization, authorizing the discharge of our patient. Two days later, alveolar haemorrhage recur, with positive toxicological tests for cannabis and the patient admits smoking cannabis by plastic "bang". We illustrate, through this case, the severity of respiratory complications caused by new methods of using cannabis, particularly with plastic 'bang', hence the need to insist of the importance of supported withdrawal and to inform young people how these techniques are serious.ssss.

Congenital cystic adenomatoid malformation (CCAM) of the lung is a rare congenital developmental abnormality, representing about 25% of all congenital lung lesions. It is very rare that presentation is delayed until adulthood. We report a case of 63-year-old woman without notable pathological antecedents in whom a systematic chest X-ray revealed multiple bilateral pulmonary nodules. The patient was asymptomatic and her physical examination was normal. CT scan showed bilateral liquid rounded thin-walled densities of various size, with a homogeneous non calcified content. The diagnosis was based on radiological findings and surgery. The result of histopathological examination obtained by thoracic surgery confirmed CCAM without malignancy. The postoperative follow up showed an excellent recovery.

Histiocytic sarcoma, proliferation araising from immunoregulatory effector system cells, is a very rare and recently recognised tumor. Diagnosis is based on immunohistochemistry and molecular genetic techniques, which allow to distinguish histiocytic sarcoma from lymphocytic proliferation, such as non-Hodgkin's. We report this rare case of multivisceral histiocytic sarcoma revealed by lung localization and for which the evolution was fatal.

During the course of generalised amyloidosis, pulmonary diseases are mainly represented by tracheobronchial involvement and diffuse or nodular parenchymal localizations. The authors report the case of a 61-year-old woman presenting exudative pleural effusion. The diagnosis of generalised amyloidosis in association with multiple myeloma with cardiac and renal involvement was established. A thoracoscopy performed during the investigation of the pleural effusion and the biopsy revealed amyloid deposits in the pleura. The patient died although melphalan/prednisone treatment was initiated. Pleural involvement in amyloidosis is without doubt under-estimated and plays a central role in the creation and persistence of pleural effusion.
