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...

hepatoblastoma (hb) is a rare tumor of infancy and childhood manifesting with hepatomegaly and abdominal distention. it is seen with increased frequency in association with congenital hemihypertrophy and renal anomalies. metastases to other organs, including the lungs, lymph nodes and even ovaries is well known. but cerebral metastasis of this tumor, especially in the absence of metastasis to o...

Renal cell carcinoma comprises about 2% of adult tumors. The overall 10-year survival rate of patients with RCC after nephrectomy is about 18-27%. The incidence of metastasis of initial RCC is about 24-28%, but this rate after nephrectomy is as high as 51%. The most common site of recurrence is the lung, however liver and bone metastases are common.There are many reported cases with late metast...

conclusions liver metastasis of neuroendocrine tumors in iran presents in a very similar manner as that seen in western countries. in about 89% of cases with liver-net, complete imaging, clinical, and pathological studies can help to identify the primary origin of the liver-net, which is very important in the patient’s management. results the most common primary site of metastatic gi-net to the...

  Background and Objective: Oral cancer accounts for less than 3% of all cancers. Despite recent improvement in diagnostic and treatment methods, the overall survival of the disease is unfavorable. Several studies have been performed to assess factors influencing lymph node metastasis and prognosis. The aim of this study was to evaluate some clinical and pathological factors influencing lymph ...

introduction: thermal ablation by microwave (mwa) has proven efficacy in treatment of primary and metastatic cancers. soft tissue tumors could be ablated completely using mwa. however, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. case presentation: a 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of tum...

a multi‑parameter quantification method was implemented to quantify retinal vascular injuries in microscopic images of clinically relevant eye diseases. this method was applied to wholemount retinal trypsin digest images of diabetic akita/+, and bcl‑2 knocked out mice models. five unique features of retinal vasculature were extracted to monitor early structural changes and retinopathy, as well ...
