congenital epulis is a very rare benign soft-tissue tumor of uncertain histogenesis, which is also known as “gingival granular cell tumor of the newborn”. it occurs almost exclusively as a single tumor along the alveolar ridge of the maxilla in newborn females. although congenital epulis is strikingly similar to the more common adult granular cell tumor histologically, in contrast to the latter...

granular cell tumor (gct) was first described by abrikossoff in 1926. gct is a rarely seen soft tissue tumor and is generally benign. while the tumor can be seen in all parts of the body it is generally located on the head and neck region, and especially on the tongue. gct is rarely seen in the anal-perianal region. in accordance with literature this case was reported because it was thought to ...

intra-abdominal desmoplastic small round cell tumor is a rare entity with a few reports worldwide. this tumor commonly occurs in children and adolescent and occurrence in adult age group is very rare. here, we describe an adult male with symptoms of intestinal obstruction due to abdominal mass, located in splenic flexure. after resection, the diagnosis of intra-abdominal desmoplastic small roun...

background and objectives: giant cell tumor of bone (gct) is often regarded as a benign tumor, but its clinical course is unpredictable, has a high rate of recurrence, and even can metastases and transform to a malignant tumor. histological features of the tumor often could not predict its future biologic behavior, so it is just called ''giant cell tumor'' without indicating malignancy or benig...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 there are a few case series of giant cell tumor (gct) in the spine and sacrum. gct in the thoracic vertebrae is even more exceptional in the medical literature. in this article we report a gct in a 25-year-old male who presented with progressive back pain and dyspnea. on contrast-enhanced multidetector computer tomography,...

background: to determine which radiotherapy parameters are associated with the tumor response of locally advanced non-small cell lung cancer (nsclc) patients undergoing concurrent chemoradiotherapy. materials and methods: thirty one patients with iiia/iiib nsclc underwent chemoradiotherapy with a median dose of 63 gy. on our actual treatments, we made radiotherapy planning to cover the planning...

It was the aim of the present study to get insight into some of the intracellular mechanisms by which the vasoconstrictor hormones angiotensin II (ANG II), arginine vasopressin (AVP), and norepinephrine (NE) inhibit renin release from renal juxtaglomerular cells. To this end a primary cell culture from rat renal cortex was established that consisted of 50% juxtaglomerular cells. The cultured ju...
