Primary Tracheal Schwannoma Masquerading as Bronchial Asthma: A Case Report and Review of Literature

Primary Tracheal Schwannoma Masquerading as Bronchial Asthma: A Case Report and Review of Literature

Early stage of primary tracheal schwannoma mimicking a foreign body

: Primary tracheal schwannoma is an extremely rare clinical entity that accounts for less than 0.5% of primary tracheal tumors. It is usually diagnosed at an advanced stage of disease, when the tumor occupied more than 50% of tracheal lumen and obstructive symptoms were seen. Treatments ranged from surgery to endoscopic resections, and the choice was influenced by the characteristics of the tumor and patient’s clinical condition. Herein, we reported a clinical case of early stage primary tracheal schwannoma that was incidentally found on high resolution computed tomography scan in a patient with asthmatic symptoms. Based on patient’s past medical history (he referred accidental inhalation of a concrete fragment several months ago), lesion size (2 mm) and endoscopic findings (lesion covered by normal tracheal mucosa, not pulsatile or friable), the tumor was misdiagnosed as a foreign body and easily resected with standard bioptic forceps during fiber bronchoscopy. Pathological findings diagnosed the lesion to be a primary tracheal schwannoma. In this case, the early diagnosis of tracheal schwannoma and its resection prevented the tumor growing and the needing of more complex treatments.

The surgical management of recurrent tracheal schwannoma

A case of a primary tracheal schwannoma refractory to endoscopic treatment in a 54-year-old male is reported. Previous treatment was by endoscopic laser debulking. Computed tomography (CT) 2 months later demonstrated a recurrent tumour involving the anterior tracheal wall with intraluminal tracheal extension. Treatment was successful by limited tracheal resection with primary anastomosis performed 2 weeks following the scan. The histology confirmed a benign neurogenic tumour derived from Schwann cells and clear margins.

A Case of Primary Tracheal Schwannoma

Although benign nerve sheath tumors have been described, primary tracheal schwannomas are extremely rare. We report a case of primary tracheal schwannoma, a rare benign nerve sheath tumor in a 58-year-old man with atypical symptoms of chronic cough, sputum and dyspnea for 2 months. Chest computerized tomography showed a 1.7 cm polypoid lesion in posterior wall of mid trachea. The results of bronchoscopic biopsy and immuno-histo-chemical studies were consistent with schwannoma. A surgical treatment of tumor resection and tracheal reconstruction by end-to-end anastomosis was performed.

Primary tracheal schwannoma a review of a rare entity: current understanding of management and followup

BackgroundNeurogenic tumors of the tracheobronchial tree are extremely rare and include neurofibroma and schwannoma. We report a case of primary recurrent tracheal schwannoma causing obstructive airway symptoms.Case presentationA 60-year-old man presented with obstructive airway symptoms due to recurrent tracheal schwannoma. Due the recurrence, size of the tumor and low surgical risk, the patient was treated with tracheal resection.ConclusionPrimary endotracheal neurogenic tumors are extremely rare, but one should consider them in the differential diagnosis of persistent upper airway symptoms. While endoscopic therapies recur nearly a quarter of the time, surgical resections do not have any recorded recurrences.

Optimal treatment for primary benign intratracheal schwannoma: A case report and review of the literature

A 53-year-old male was admitted to Xinhua Hospital (Shanghai, China) due to coughing and dyspnea that had persisted for half a year, with aggravation of chest tightness and dyspnea for 1 week. Chest computed tomography (CT) revealed a mass within the distal third of the trachea. Flexible bronchoscopy confirmed an ~2.0 cm, smooth, tan-colored mass in the trachea, 2 cm above the carina. Endoscopic resection by argon plasma coagulation combined with electronic snaring was applied, however, recurrence was found 2 weeks later. Finally, the tumor was completely removed by surgery and the post-operative course was uneventful. Since schwannoma is rare in the intrapulmonary region and extremely rare in the trachea, a review of 51 cases of primary tracheal schwannoma previously reported in the English literature was performed. The majority of cases occurred in adults and were usually located in the distal third of the trachea. The predominant tumor size was 1-3 cm and airway obstruction symptoms were common. Half of the patients were misdiagnosed with asthma, and CT scan and bronchoscopy were contributory to the correct diagnosis. The treatment of choice depended on the patient's condition, however, surgery should be chosen in the event of local recurrence following endoscopic treatment.

Tracheal schwannoma: Completely resected with therapeutic bronchoscopic techniques.

Tracheal schwannomas are rare benign tumors of the trachea. There are only a few reported cases in the literature. Surgeons have generally resected these tumors, whereas bronchoscopists have attempted to remove them bronchoscopically. We report a case of tracheal schwannoma which was completely resected using bronchoscopic techniques.

Schwannome trachéal bénin traité par exérèse endoscopique et cryocoagulation

Tracheobronchial schwannoma is a rare benign airway tumour. There is no evidence to guide treatment for this condition. A 76-year-old woman with a history of ischemic cardiomyopathy was hospitalized for dyspnoea with bronchial symptoms. Incidentally, the CT scan of the chest identified a tracheal mass. The bronchoscopy revealed a multilobar and regular whitish tumour with moderate vascularisation that was not causing obstruction. The patient was treated by complete resection with a rigid bronchoscope followed by cryotherapy. The histopathologic diagnosis was of a benign schwannoma without malignant elements. There was no recurrence during the follow-up period. There is no consensus as to the optimal management of tracheal schwannoma because of the rarity of this tumour. Our observation supports the use of endoscopic resection with the additional of local cryotherapy which may reduce the risk of recurrence.

Surgery for Primary Tracheal Tumors: Experience on Four Cases

Primary tracheal tumors are rare occurrences. The most commonly seen type is the epidermoid carcinoma followed by adenoid cystic carcinoma. Despite being less frequent, schwannomas of primary tracheal origin can also be seen. Of such cases, we had four who had been operated: three for adenoid cystic carcinoma and one for tracheal schwannoma. We analyzed the experiences of our clinic besed on these cases and compared this to those of reported cases. All cases underwent tracheal resection with median sternotomy. One case required additional left hemi-clamshell incision. One case died due to a tracheavascular fistula that developed during the operation. Other cases are at second, third and seventh postoperative years and free of problems. Despite all known risks, the most appropriate type of treatment for primary tracheal tumors is surgery. Radiotherapy is administered as an adjunct treatment to such patients. The rate of fatal complications increases together with the increase in the size of the tracheal segment to be resected. doi:10.4021/jmc53w

Tracheal schwannoma: a rare tracheal tumour.

Primary tracheal tumours are histologically similar but 100 times less common than main stem tumours. We report a case of primary tracheal schwannoma in a middle aged man. He had chronic cough for 2 years, and developed hemoptysis and stridor in the days preceding to presentation. He was treated by resection of the tumour and primary anatomosis of the trachea. The patient recovered well after surgery and had a near normal PEFR after one and a half year of follow-up and bronchoscopic examination excluded any recurrence.

A Case of Intratracheal Schwannoma Presenting to the Emergency Department With a Diagnosis of Asthmatic Attack: A Clue to Suspect the Cause of Upper Airway Obstruction to Be Other Than Asthma

We have read with interest the article by Erol et al. reporting a case of tracheal schwannoma presenting as acute asthmatic attack ( 1 Erol M.M. Uzun H. Tekinbas C. Gunduz A. Turedi S. Kosucu P. A case of intratracheal schwannoma presenting at the emergency department with a diagnosis of asthmatic attack. J Emerg Med. 2008 April 23; ([Epub ahead of print]) PubMed Google Scholar ). Schwannoma is a rare cause of upper airway obstruction, often misdiagnosed as asthma, that does not respond to therapy and often presents late in its course, with iatrogenic manifestation of excessive steroid use, such as Cushing's syndrome. Schwannoma rarely presents as acute asthma. Recognition of the cause of the upper airway obstruction is essential to preclude affected patients being prescribed lengthy courses of systemic corticosteroids ( 2 Kenyon N.J. Jarjour N.N. Severe asthma. Clin Rev Allergy Immunol. 2003; 25: 131-149 Crossref PubMed Scopus (9) Google Scholar , 3 Tilles S.A. Differential diagnosis of adult asthma.

Therefore, relevant points regarding this case are presented to provide clues for when to search for alternate causes of obstruction other than asthma (i.e., asthma imitators).

A rare tumor simulating asthma: The tracheobronchial schwannoma

Summary Primary tracheal schwannoma is exceptional and may simulate asthma. We report a new case of tracheobronchial schwannoma mimicking severe asthma in a 37-year-old man. Histologic diagnosis is made by surgery after the failure of the endoscopic resection. This tumor, even rare, must be considered in the differential diagnosis of patients with obstructive airway symptoms, especially if unresponsive to conventional therapy.
