[Inflammatory pseudo-tumor of the chest]

The inflammatory pseudotumor are rare benign tumors that are the subject of a recent interest, motivated in part by the discovery of a chromosomal abnormality, and secondly, by the existence of rare malignant forms. We report a retrospective study spread over 8 years [1999- 2006] during which we have reported 6 cases of inflammatory pseudotumor. The diagnosis was based on clinical, radiological and histological findings. The incidence of ITP was 1.14% among tumors, patients' age ranged between 14 and 58 years and the sex ratio was 5 women for every man. One patient had a history of treated pulmonary tuberculosis and a history of sarcoma of the thigh treated was reported in one case. Clinical signs were dominated by hemoptysis, chest pain and cough with purulent sputum. The clinic and paraclinical objectified, a heterogeneous left process basal [one case], an excavated lesion of the right hemi thorax [two cases], right upper lobe mass [two cases] and endotracheal process [one case]. All patients underwent surgery for diagnostic and therapeutic reasons and confirmation was based on a pathological examination of surgical specimens. The immediate postoperative course was uneventful and no recurrence was noted. The etiology of these tumors is unclear, the clinical, radiological, and the preoperative cytohistologie can not put a definitive diagnosis, so that the surgery is performed for diagnostic and therapeutic reasons. Careful monitoring is necessary to prevent any recurrence or malignant transformation which is rare but certainly formidable. Through these observations and a literature review, the authors propose an update on the clinical, paraclinical and therapeutic aspects of these cases

[ fibrous osseous dysplasia]

The fibrous osseous dysplasia is a rare congenital condition characterised by the replacement of the medullary canal spongy os by a fibrous tissue proliferation. we reported a case of a young girl, 21 years old, who suffered from thoracic pain since more than one year, with apparation of the axillary arch which progressivaly increase in volume since six months. Examination revealed a fixed hard tumefaction, the thoracic radiography showed two souffle osteolytic images near the medium arc of the fifth left rib and fourth right rib. The osseous scintigraphy revealed an hyperfixation touching the right hemiface. The cranio-facial scan showed an interesting aspect of [frosted glass] of the clivus. The remodeling mark dosage of the osseous alkaline phosphatase was of 2321U/L. A mass biopsy was done which confirmed the diagnosis. the combination of costal and clivus fibrous dysplasia which had been never reported in literatures and the difficult therapeutic decision in front of this polystotic picture makes our case a particular case
