Extra-skeletal Ewing’s sarcoma is a rare soft tissue malignant neoplasm, morphologically indistinguishable from skeletal Ewing’s sarcoma. The usual sites of involvement are the soft tissues of para-vertebral region, chest wall, and lower extremity. Extra-skeletal Ewing’s sarcoma is rare in the head and neck region and very few cases are reported in the parotid gland. The cytological features...

Schwannomas may occur anywhere in the soft tissues or viscera, but do not commonly involve the pancreas and retroperitoneum. We present a case of benign pancreatic schwannoma which clinically simulated a malignant neoplastic process.

Introduction After the publication of Task Group number 43 dose calculation formalism by the American Association of Physicists in Medicine (AAPM), this method has been known as the most common dose calculation method in brachytherapy treatment planning. In this formalism, the water phantom is introduced as the reference dosimetry phantom, while the attenuation coefficient of the sources in the...

Metab. 39): E728–E738, 1999.—We evaluated the effects of 8 mo of calorie restriction [CR: 60% of ad libitum (AL) food intake] on glucose uptake by 14 tissues in unanesthetized, adult (12 mo) F3443BN ...

Metastatic tumors account for 1% of all oral malignancies. Metastasis to jaw bones is common, particularly in the mandible, rare in the oral soft tissues, and account for only 0.1% of oral malignancies. The majority of metastatic cases (70%) reported in the literature have primary tumors located in the lung, breast, kidney, and colon. Metastasis is a biological complex process that involves det...
