The case history is presented of a patient with a tracheal schwannoma who remains free of disease five and a half years after laser resection. This illustrates the potential of this approach in the management of tracheal schwannoma.

BACKGROUND Neurogenic 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 PRESENTATION A 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 ...

The co-existence of meningioma and schwannoma as 2 distinct histologic components within the same tumor has been described in neurofibromatosis 2 (NF2), but the co-existence of both tumors without evidence of NF2 is much rarer. Here, we are reporting a case of mixed schwannoma with meningioma without clinical evidence of NF2. In an adult Saudi lady with progressive left-sided hearing loss, left...

A rare case of duodenal schwannoma is reported. A 69-year-old man was admitted for evaluation of melena. Endoscopy and hypotonic duodenography showed a submucosal tumor in the third part of the duodenum. Biopsy findings were suggestive of leiomyosarcoma, therefore pancreatoduodenectomy was performed. Hematoxylin-eosin staining of the resected specimen showed interlacing bundles of spindle-shape...

Schwannomas, arising from nerve-sheath Schwann cells, rarely occur in the lip area. A Medline search in English literature from 1966 to 2002 revealed only 6 documented cases of schwannomas of the lip. We report the unusual case of a 22-year-old female patient who developed a schwannoma of the upper lip. Histopathological examination and immunohistochemical staining studies were performed, with ...

Schwannoma arising within breast parenchyma is very rare. This report describes such a case in a 58-year-old woman. The tumor, which measured 4.4 x 3.5 x 2.1 cm, was painless, mobile and elastic-soft. Mammography showed a well-circumscribed, oval-shaped nodule without microcalcifications. At ultrasonography it appeared as a hypoechoic solid mass. Fine-needle cytology revealed several clusters o...

Intrasellar location of schwannoma is extremely rare, although intracranial schwannomas account for up to 8% of all primary brain tumors. An unusual case of an intrasellar schwannoma radiographically and clinically simulating a pituitary adenoma is reported. A 39-yr-old man presented a 10-month history of visual disturbance and decreased libido. Neurological examination showed poor visual acuit...

A 56-year-old man was admitted to our hospital with a complaint of massive hemoptysis. Bronchoscopy revealed a tumor obstructed the orifice of the right lower lobe bronchus. The diagnosis of endobronchial schwannoma was made by broncho-fibroscopic biopsy. Schwannomas are benign tumors which originate from schwann cells. They rarely occur in the trachea or bronchus. On the other hand symptoms in...

394 Objective: To report a very unusual occurrence of obstructive external ear canal schwannoma. Study Design: Case report and review of relevant literature. Materials and Methods: Presentation of patient data, CT imaging, surgical therapy and histological findings. Results: A schwannoma completely obstructed the opening of the external ear canal without tympanic membrane involvement. CT scan s...
