Synchronous Contralateral Benign and Malignant Parotid Gland Tumors: Case Report

Multiple primary parotid gland tumors are rare, accounting for 1.7-5% of all parotid neoplasms, and the occurrence of bilateral parotid gland tumors is even lower (1.3-3.5%). These tumors can be synchronous or metachronous and the most common histologic type of bilateral parotid gland tumors is Warthin tumor (79.2-90%). Combined benign and malignant lesions and bilateral neoplasms of different histologic types are even less frequently found.

A Bulky Mass of the Infra-Temporal Fossa

Tumors located in the parapharyngeal space are rare. They account for 0.5% of the whole tumors of the head and neck. Benign neoplasms are the most common with a rate of 70 to 80%, 40 to 50% originate in the salivary glands ; half of them are represented by the pleomorphic adenoma. We report the case of 38 old-year woman with in which the diagnosis of parapharyngeal space was made. The patient underwent a complete removal of the mass. The histological exam revealed a pleomorphic adenoma. No postoperative complications.

Potentials, Limitations and Future Directions of MR Contrast Media in Ablation Therapies

ImagingIntroductionMR contrast media have become an indispensable part of magnetic resonance (MR) imaging, but their roles in ablation therapies are still controversial. The interactions between physical/biological properties of MR contrast media (Longitudinal=T1, transverse=T2 and susceptibility=T2* relaxation times) and diseased tissues (perfusion, edema, hemorrhage and coagulative necrosis) play important roles in differentiating pathologic and ablated tissues.

Effect of Neoadjuvant Chemoradiotherapy on Pathologic Stage and Survival in Patients with Locally Advanced Esophageal Cancer

The treatment of resectable stages of esophageal cancer often involves pre-operative concurrent chemoradiotherapy. This study aims to evaluate the effect of cisplatin/5-fluorouracil (5-FU)-based neoadjuvant chemoradiotherapy on pathologic stage and survival in patients with locally advanced esophageal cancer.

Sudden Death Due to Sarcoma: An Unusual Case and Literature Review

Sudden death has varied causes, and autopsy is usually required to determine cause of death. Sarcoma involvement is very infrequent, and detailed pathological evaluation is needed for correct diagnosis.

Schwannoma Palate in Children: Rare Case

Schwannoma is a benign tumor that originates from the presence of Schwann cells of the peripheral nerves. They are usually asymptomatic, do not recur, and malignant transformation is rare.

Hypoglossal Schwannoma: A Rare Case Report

Hypoglossal schwannomas are rare cranial base neoplasm arising from schwann cells of the XIIth cranial nerve. We report a case of 45 year old lady with history of headache for 2 years and difficulty in swallowing for 1 year. On evaluation, she was found to have left hypoglossal paresis, atrophy of tongue muscles on left side and a smooth oropharyngeal bulge on left side.

Profile of Cytokines (IL-1β, TNF- α and IL-10) in Eyelid Tumors

Tissue cytokine levels (IL-1β, TNF-α and IL-10) have been utilized for screening, diagnosis, prognostication and treatment of tumors. The current study, therefore, purports to measure the levels of common cancer associated cytokines in histopathologically confirmed tissue samples of eyelid tumors.

Persisting Cough as the Single Presenting Symptom of an Intrathoracic Tumor in a Nine-Month-Old Child with Adenovirus Airway Infection

We report on a nine-month-old girl who presented with persisting cough, and diminished ventilation of the left hemithorax. Viral pneumonia was suspected after Adenovirus detection by PCR, but chest X-rays showed a persistent shadowing of the left hemithorax and persistent coughing despite clinical improvement. Because of the discrepancy between clinical and radiological signs further investigations by ultrasound and CT scan were performed, which visualized an intrathroracic tumor. Histopathology confirmed diagnosis of a teratoma.

Development of Severe Hypophosphatemia from Acquired Fanconi Syndrome during Treatment with Abiraterone

The first patient was a 77 year old man who had been on abiraterone for 12 months before his phosphorous was checked. At that point, it was 0.6 mg/dl, which is severely decreased. A full work up for hypophosphatemia showed normal parathyroid hormone and 25-hydroxyvitamin D. A urine study showed inappropriate excretion of phosphorous along with aminoaciduria and normoglycemic glucosuria.

Unusual Large Ethmoidal Osteoma with Orbital Extension

Large osteomas of the fronto-ethmoidal cavities are very rare benign tumors. Headache and ocular signs are the most common symptoms. Imaging allows the diagnosis. Treatment of ethmoid sinus osteoma is surgical. One case with orbital extension is reported and discussed. A 30 years-old male; complaining of swelling of themedial angle of the right eye. Computed tomography showed a right ethmoidal process with orbital extension. The tumor was removed through an external ethmoidectomy.
