1/7. Inflammatory pseudotumor of the trachea.Primary tracheal tumors are extremely rare, and the majority of them are malignant. Inflammatory pseudotumor is a benign, tumorlike lesion, most likely of a reactive nature. Its basic morphologic characteristic is spindle cell (myoblasts and fibroblasts) proliferation with a variable number and type of inflammatory cells. A case of intratracheal inflammatory pseudotumor in a 14-year-old boy is presented together with a review of all similar lesions in the available literature. The discussion includes the presentation of tracheal tumors, their basic morphologic and immunohistochemical characteristics, and treatment modalities that are available. The surgeon must exercise caution not to perform radical surgery based on the initial pathologic diagnosis from the intraoperative frozen section, because the prognosis of these benign lesions generally is excellent. This is the second reported case of intratracheal inflammatory pseudotumor successfully endoscopically vaporized using a CO(2) laser, which is an excellent alternative in cases in which surgical treatment is feasible.

2/7. Inflammatory pseudotumor of the trachea."Inflammatory pseudotumor" is a broad descriptive term used to describe a localized collection of inflammatory and fibroblastic cells. It is an uncommon lesion that can mimic a tumor when it is located intraluminally in the trachea or bronchi. Because an inflammatory pseudotumor has an abundance of polyclonal plasma cells, its etiology (postinflammatory vs immunologic) is still being debated. We report a new case of inflammatory pseudotumor that arose in the trachea of a 20-year-old man. We also review the histologic and clinical characteristics of this lesion.- - - - - - - - - - ranking = 0.75keywords = trachea (Clic here for more details about this article) |
3/7. Inflammatory myofibroblastic tumor (inflammatory pseudotumor) of the neck infiltrating the trachea.Inflammatory myofibroblastic tumor (IMT), popularly known as inflammatory pseudotumor, is a slow growing quasi-neoplastic lesion with a distinct histologic appearance and benign clinical course. A case of a neck IMT with infiltration into the trachea causing asthmalike symptoms in a 12-year-old girl is described. Both tracheal and neck IMT have been described, but no other case has displayed this infiltration. A review of the pertinent literature and the etiology, diagnosis, treatment, and outcomes of this tumor are discussed. It is important to consider IMT in a differential diagnosis because it can be easily misdiagnosed as a malignancy. A surgeon must not perform radical surgery, radiation, or chemotherapy until a final pathologic diagnosis is made because of the nature of this lesion.- - - - - - - - - - ranking = 0.75keywords = trachea (Clic here for more details about this article) |
4/7. Calcifying fibrous pseudotumor of the myocardium.Calcifying fibrous pseudotumor is an uncommon tumor first described in 1988 as a childhood fibrous tumor with psammoma bodies. The typical pathological findings are those of a densely collagenized fibrous tumor with psammomatous and dystrophic calcification accompanied by a lymphoplasmacytic infiltrate. To date these tumors are reported in subcutaneous and deep soft tissues of the extremities and trunk, groin, scrotum, pleura, mediastinum, paratracheal region, peritoneum, neck, mesentery, omentum, serosa, lung, bone, and gallbladder. We describe a 17-year-old girl with a myocardial calcifying fibrous tumor, and we review the English literature.- - - - - - - - - - ranking = 0.125keywords = trachea (Clic here for more details about this article) |
5/7. Subglottic plasma cell granuloma: report of a case.A case of subglottic and tracheal plasma cell granuloma masquerading as tumor invasion by thyroid malignancy was successfully treated using CO2 laser. A 55-year-old woman with a history of inspiratory stridor of almost 10 months duration was admitted to our clinic, and examinations revealed a mass in the subglottic space and trachea obstructing the airway. CT scan findings was suggestive of tumor invasion from a thyroid gland malignancy, however, histopathological examination of a biopsy specimen showed it to be plasma cell granuloma. Cases of plasma cell granuloma of the larynx and trachea are reviewed and discussed.- - - - - - - - - - ranking = 0.375keywords = trachea (Clic here for more details about this article) |
6/7. Plasma-cell granuloma of the trachea.A case of intratracheal plasma-cell granuloma is presented together with a review of the literature. The discussion includes the presentations of tracheal tumours, the pathology of this lesion and its variants, the clinical course and the treatment modalities that are available, and emphasizes a more conservative approach.- - - - - - - - - - ranking = 0.75keywords = trachea (Clic here for more details about this article) |
7/7. Inflammatory pseudotumour of the trachea: report of a case in an eight-year-old child.A polypoid inflammatory pseudotumour was diagnosed in the trachea of an eight-year-old child who presented with asthmatic symptoms. The tumour showed 80 per cent blockage of the lower trachea and consisted of proliferating spindly fibroblastic cells admixed with a variable number of inflammatory cells. The literature on childhood inflammatory pseudotumours is reviewed together with the differential diagnosis of other polypoid mesenchymal tumours of the trachea.- - - - - - - - - - ranking = 0.875keywords = trachea (Clic here for more details about this article) |
