[Benign schwannoma: a case report about a uncommon localization]

Schwannoma is a benign slow growing nerve sheath tumor which generally originates from cranial or spinal nerve roots. Peripheral nerve localisations are scarce. We report the case of a 76-year man who presented with a laterosternal chest wall mass located in the fourth intercostal space. Diagnosis of intercostal benign schwannoma was suggested by medical imaging and confirmed histologicolly upon surgical removal. Chest wall solitary schwannoma is exceptional. Our case is still more interesting by its peripheral localisation and late occurence following a chest trauma

[Reexpansion pulmonary edema a vacuo: a case report and literature review]

Reexpansion pulmonary edema is a rare and potentially lethal complication with a 15 to 20% mortality. We report one case of pulmonary edema after evacuation of spontaneous right pneumothorax The pathophysiology of reexpansion pulmonary edema remains obscure; mechanical and inflammatory processes [production of Inerleukin 8 - and Leukotrienne B4] seem incriminated. Duration and severity of lung collapse and the rate of reexpansion appear to be the main causes justifying preventive measures. Curative treatment is based on oxygenation and lower aspiration pressure

[Costal hydatid cyst[about 2 cases]]

Hydatidosis is an endemic affection in our country. Hepatic and pulmonary localisation is the most frequent. The other localisation especially in the bone, are exceptional. We report 2 cases of costal hydatid diagnosed on 17 and 33 yeas old male patients admissed for parietal tumor respectively localized in cervix and thorax. The diagnosis,suspected on chest tomography,is confirmed by histologic patterns of resected rib
