Endolymphatic sac tumor is rare, locally aggressive hypervascular tumor of papillary structure, arising from the endolymphatic duct or sac in the posterior petrous bone. We present four cases with this tumor. Two patients were male and the other two were female. Age of each patient was 15, 52, 58, and 67 years. Three patients presented with progressive hearing loss and sustained vertigo for months to years and another one was referred for the tumor detected in routine medical check-up. Preoperative embolization was performed in 3 patients. Complete excision of the tumor was achieved in all patients using translabyrinthine or retrosigmoid approach. Herein, we describe the clinical and radiographic features, surgical treatment and pathologic findings with a review of the literature.

Adenoid cystic carcinoma is a rare primary tracheal tumor and this tumor behave slow growth, low-grade ma!ignancy, locally invasion and long-term host survival. Operation with the primary goal of complete excision is the treatment of choice but this tumor require excessive margins at surgical removal because of locally invasive cancer. A 45-years-old male patient had complained paroxysmal coughing from 1 year ago prior to admission and was diagnosed pre-operatively as endotracheal adenoma. He had been treated by operation, and combined with radiotherapy by 4 MeV. Lineal Accelerator. The tracheal mass was removed by tracheo-bronchotomy transpleurally and right total pneumonectomy was performed. There was post-operative course uneventfully and no post-operative complication. The patient Is free from cancer until post-operative 1 year clinically and alive with good healthy.

Castleman`s disease is a rare disease entity of unknown etiology, with the characteristics of large, well marginated benign lymph node hyperplastic mass. This disease occurs predominantly in the mediastinum but also occurred in other areas of the body usually where lymph nodes are normally found. They have been divided into two histologic types: the hyaline vascular lesion which comprises over 90% of the cases; the plasma cell lesions, which was characterized by large follicle with plasma cell and systemic manifestation, such as fever, anemia elevated ESR, hypergammaglobulinemia, hypoalbuminemia. This disease have behaved in a benign fashion and complete surgical excision is the choice of treatment. We experienced a case of Castleman`s disease which was treated by surgical resection through the thoracotomy, and has good postoperative and follow up result. We report a case of the Castleman`s disease with its review.

Branchiogenic carcinoma is extremely rare and is defined as a malignant degeneration within the confines of epithelial remnants derived from the embryonal branchial apparatus. Two major diagnostic criteria are histologic proof of transitional area from normal cyst epithelium to invasive squamous cell carcinoma and absence of an identifiable primary carcinoma elsewhere. A 62-year old woman visited our department complaining of a non-tender, movable mass in left upper lateral neck. After a complete mass excision, histopathologic diagnosis of the surgical specimen was branchiogenic squamous cell carcinoma. I report a case of branchiogenic carcinoma with literature review.

Desmoplastic fibroma is one of the uncommon osseous tumors that present in the skull. Although classified as benign tumor, desmoplastic fibroma exhibits local aggressiveness and has a high potential for recurrence. The most common sites include metaphysis of long bones and mandible. Only 15cases have been described in the skull. We report the 16th case of desmoplastic fibroma of the skull.

Giant spinal schwannoma of the cauda equine involving many nerve roots is rare, and ossification is usually not observed in the schwannoma. A 21-year-old man presented with a 12-month history of urinary dysfunction and numbness below the buttocks. Plain radiography showed scalloping of the posterior surface of the vertebral bodies from L4 to the sacrum, and magnetic resonance imaging and computed tomography revealed a giant cauda equina tumor with dystrophic calcification. The tumor was completely removed, with intraoperative neurophysiologic monitoring. Histopathologic examination showed that the tumor was a schwannoma. The patient's postoperative course was uneventful, with urinary function and numbness gradually improving. Although a giant schwannoma accompanied by dystrophic calcification is extremely rare, such a tumor can be removed safely and completely by meticulous dissection and careful neuromonitoring of the cauda equina spinal nerves involved in the tumor.

Hemangioblastomas in the pituitary stalk are especially rare. Most pituitary stalk hemangioblastomas reported in the literature were associated with von Hippel-Lindau (VHL) disease. Here, we report only the 3rd case of sporadic pituitary stalk hemangioblastoma diagnosed in a 60-year-old woman. Despite the danger of potential complications due to excessive vascularity or proximity to important neural structures, the tumor in our case was successfully removed while preserving pituitary function. In this case, complete surgical excision was shown to be an effective treatment option for symptomatic pituitary stalk hemangioblastoma, and we suggest careful evaluation of any highly enhancing mass with a signal void in the pituitary stalk preoperatively, even if no VHL disease is evident.

Epiglottic cysts cause stridor mimicking asthma and hinder intubation in surgery. A huge cyst can obstruct the airway, making laryngeal examinations impossible. Before surgery, complete visualization of the larynx is necessary for the successful excision of a cyst. If laryngeal examination fails, computed tomography (CT) scanning can provide detailed information. Virtual endoscopy based on CT data reconstruction can yield a detailed three-dimensional image of the larynx. Here, we report two cases of epiglottic cysts along with virtual endoscopic findings and surgical photographs.

From 1981 to 1990, we performed operation on 6 patients with cardiac myxomas, which were located in the left atrium in 5, in the biatrium in 1. There were 3 male and 3 female patients ranging in age from 13 years to 69 years. Symptoms included exertional dyspnea, palpitation and signs of systemic illness. Diagnosis was accomplished by angiography[3 patients] and echocardiography [3 patients]. In all cases, myxomas were excised successfully through incision of interatrial septum There were no operative deaths or intraoperative embolic episode. Follow-up has been 40.0\ulcorner40.6 months[ranging from 1 month to 9 years], results of each patient were excellent We suggested that excision of intracardiac myxomas is curative and follow-up results are excellent. The transseptal approach provides adequate exposure and allows complete removal of the tumor regardless of its location.
