1/59. Tall cell variant of papillary carcinoma arising from ectopic thyroid tissue in the trachea.Ectopic thyroid tissue within the submucosa of the trachea is a rare cause of upper airway obstruction. Primary neoplasms arising from such thyroid nests are rare. This report describes a case of tall cell variant of papillary carcinoma arising from ectopic thyroid tissue in the trachea.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
2/59. Successful primary radiation therapy of adenoid cystic carcinoma of the lung.Adenoid cystic carcinoma is a distinctive malignant neoplasm generally arising from minor salivary glands, that arises infrequently as a primary tumor in the lung. Surgery has been considered the primary treatment, with radiotherapy generally utilized as adjuvant or palliative treatment. We report a patient in whom primary radiotherapy was sucessfully applied to treat adenoid cystic carcinoma involving the distal trachea, carina, and both main stem bronchi. A total dose of 66 Gy was delivered in 2-Gy fractions over a 7-week period. Clinically and histologically complete remission was achieved without evidence of disease during a 27-month follow up.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |

This paper described such a case in a young female in whom the mass that progressed to cause almost complete obstruction before it was diagnosed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
4/59. Granular-cell tumor of trachea masquerading as Hurthle-cell neoplasm on fine-needle aspirate: a case report.We report on a case of extraluminal tracheal granular-cell tumor which was interpreted as a Hurthle-cell neoplasm of the thyroid on fine-needle aspirate. review of the literature reveals only one other such case. The patient was a 35-yr-old female who presented with an enlarged thyroid. Aspiration cytology revealed a syncytium of cells with abundant granular cytoplasm interpreted as a thyroid follicular neoplasm with Hurthle-cell change. However, histology of the resection specimen with immunohistochemistry confirmed it as a granular-cell tumor. The cytologic differential diagnosis of neoplasms with oncocytoid cytoplasm in and around the thyroid should include granular-cell tumor of the trachea.- - - - - - - - - - ranking = 7keywords = neoplasm (Clic here for more details about this article) |
5/59. Tracheal lipoma: a rare intrathoracic neoplasm.Primary tracheal lipomas are extremely rare neoplasms. The typical patient is a middle-aged man with complaints of cough and shortness of breath. Often, the diagnosis is delayed, and patients are treated for asthma or bronchitis. The diagnosis of a tracheal lipoma is best approached by computed tomography (CT) and bronchofibroscopy. Tracheobronchial lipomas may be successfully excised endoscopically or by laser therapy. Open surgical resection is required when the lipoma extends extraluminally.- - - - - - - - - - ranking = 5keywords = neoplasm (Clic here for more details about this article) |
6/59. glomus tumor of the trachea.Extracutaneous glomus tumors are uncommon and rarely occur in the trachea. We describe a 73-year-old man with a glomus tumor of the trachea who presented with cough, dyspnea, chest pain, and hemoptysis. A curative segmental tracheal resection with primary reconstruction was performed with no recurrence at 6-year follow-up. The clinicopathologic features of this unusual neoplasm are discussed with a review of the literature.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
7/59. granular cell tumor of the trachea in a child.Granular cell tumors are benign neoplasms found most commonly in the head and neck, particularly the tongue. They have, however, been described in all areas of the body. Their presentation in the trachea is exceedingly rare, with their presence in the pediatric trachea being an even rarer occurrence. We describe a case of a granular cell tumor of the trachea in a 10-year-old boy with a dramatic, almost lethal, presentation. This is followed by a review of the literature, including pathology and treatment options.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
8/59. Tracheal reconstruction with free composite cartilage graft: a case report.Tracheal resection followed by an end-to-end anastomosis has been the method of choice for the treatment of tracheal neoplasms. We hereby report a 40-year-old female patient in whom we performed reconstruction with composite nasal septal cartilage graft following one-staged tracheal resection. Histopathologic diagnosis was well-differentiated adenoid cystic carcinoma. Fiberoptic and biopsy examinations made within the first postoperative month showed no residual or recurrent tumor at the resection site. The patient received radiotherapy postoperatively. She has been free of disease for 18 months. To our knowledge, the use of composite nasal septal cartilage graft in the reconstruction of tracheal tumors has not been previously reported.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
9/59. Inflammatory myofibroblastic tumor presenting with tracheal obstruction in a pregnant woman.Inflammatory myofibroblastic tumor (IMT), also known as inflammatory pseudotumor, is a benign lesion predominantly found in the lung and abdomen. Sporadic cases have been reported in the trunk, genitourinary tract, and extremities as well as in the head and neck. Of critical importance is this entity's correct histopathologic diagnosis that differentiate it from malignant neoplasms such as spindle cell carcinoma and fibrosarcoma, benign tumors such as neurofibroma, and other pseudoneoplastic lesions such as nodular fasciitis. Correct diagnosis is followed by wide local excision to prevent recurrence; however, treatment must be tailored to the location of tumor and the condition of the patient. We present a unique case of IMT of the trachea presenting with acute upper airway obstruction in a pregnant woman. Diagnostic considerations as well as the anesthetic and surgical approach are discussed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
10/59. Endotracheobronchial neurofibromas.Among benign tracheobronchial neoplasms, neurofibromas of neurogenic origin are exceedingly rare. In a search world literature, only 23 cases of endotracheobronchial neurofibromas in 21 series were found. We report another case of a 52-year-old man who presented to our hospital with the symptoms of intermittent productive cough and fever. bronchoscopy revealed a round tumor obstructing the lumen of the right main bronchus. Right sleeve pneumonectomy was performed, and neurofibroma was confirmed by pathologic examination. The literature is reviewed.- - - - - - - - - - ranking = 1keywords = neoplasm (Clic here for more details about this article) |
