Background: Tumors involving the hand skeleton are rare. However, a basic knowledge of hand tumors is necessary for every clinician. This is due to the importance of distinguishing typical benign tumors from life or limb threatening malignant ones. Methods: This study is a review of 99 cases of osseous hand tumors presented to the department of orthopedic surgery, Imam Khomeini Hospital in Te...

background gastrointestinal stromal tumors (gists) are potentially malignant tumors; however their behavior and response to treatment is dependent on the type of mutation and immunohistochemical expression of antigens. it is recommended to perform routine molecular and immunohistochemical tests in kit and platelet derived growth factor receptor alpha (pdgfra) molecules for making decision regar...

conclusions unfortunately the tumor was unresectable and just an incisional biopsy was performed. she received chemotherapy as palliative care. case presentation we presented a 56-year-old woman admitted to our center with lung emboli symptoms. transthoracic and transesophageal echocardiography (tte and tee) demonstrated very large size (more than 10 cm diameter) multilobulated mass with mobile...

The oncogenic capacity of a myc-containing strain of feline leukemia virus (FeLV), termed LC-FeLV, has been examined after inoculation of the virus into neonatal kittens. Like other myc-containing strains of FeLV, LC-FeLV may induce with relatively short latency, but does not necessarily induce, thymic lymphosarcoma in viremic animals. Naturally occurring and experimentally induced tumors are T...

malakoplakia is a rare disease with undefined etiology that has been almost exclusively reported in urology and pathology journals. we are presenting a case of colonic malakoplakia in an i8-year old young man who was referred to us with a four-year history of intermittent rectorrhagia. the pathological examination of the endoscopically resected specimen revealed pathognomonic features of malako...

to investigate the effects of the two-pore-domain potassium (k2p) channel task-3 in a syngeneic murine model for malignant glioma. malignant or high-grade glioma (who grade iii and iv) are the most common and most aggressive primary brain tumors in adults. despite aggressive multimodal therapy, the outcome of patients with malignant glioma remains poor. however, recent phase i and ii trials hav...

Af-Hydroxy-2-naphthylamine produced bladder tumors in three of four dogs when administered over a period of 30 months (dogs were sacrificed 15 months later) in dimethyl sulfoxide solution by repeated instillation directly into the bladders. ./V-Hydroxy-1-naphthylamine was more carcinogenic than TV-hydroxy^-naphthylamine by administration to rats, but the reverse was observed in four experiments...

Congenital epulis, a rare benign neonatal tumor, is found more commonly in females and can be a cause of extreme anxiety in parents and health professionals. There is a potential of abnormal dentin development in surgically treated patients. These children should be followed by a pediatric dentist. A watchful approach rather than surgery is justified in small tumors because of the risk of abnor...

Portal biliopathy is the complex of abnormalities of extrahepatic and intrahepatic bile ducts, cystic duct, and gallbladder, arising as a result of extrahepatic portal vein obstruction and noncirrhotic portal fibrosis, which can be caused by coagulopathies, tumors, inflammation, postoperative complications, dehydration, and neonatal umbilical vein catheterization. We report a case of a 55-year-...
