Introduction: Few studies on benign soft tissue tumors of oral cavity have been conducted in an Iranian population. The purpose of this study was to evaluate the prevalence of the benign soft tissue tumors of the oral cavity in three central pathology centers of Rasht, Iran. Materials and Methods: In this retrospective study, all benign soft tissue tumors of the oral cavity, were retrieved fro...

Introduction: The global incidence of gastric cancer (GC) has been decreased dramatically in recent decades and characteristics of this cancer has been changed. Most of these changes can be resulted from changes in dietary and nutritional habits. This cancer is the most common cancer in north and northeast of Iran. In present report we will briefly summaries the gastric tumor location in a popu...

  Schwannoma(neurilemmoma) is a benign tumor originates from Schwann cells. Ancient (degenerated) schwannoma is a long-standing schwannoma with degenerative changes. Head and neck region is one of the most common sites for nerve sheath tumors but intraosseous schwannoma is rare. The mandible is the most common site of occurrence for this lesion. We report a rare case of intraosseous ancient sc...

Short-term tests to detect genetic, chromosomal, or DNA damage are now required by regulatory agencies for any new compound proposed for commercial production. Furthermore, full-scale carcinogenicity tests may be required for certain compounds. In this circumstance, the compound-related fac tors, including stability, purity, physical properties, and chem ical structure and reactivity must be co...

Introduction: Photothermal therapy (PTT) is a nanotechnology-assisted cancer hyperthermia approach in which the interaction between laser light and plasmonic nanoparticles generates a localized heating for thermoablation of the tumor. Recent efforts in the area of PTT follow two important aims: (i) exploitation of targeting strategies for preferential accumulation of plasmonic ...

background and aims. although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. this study aimed to evaluate the efficacy of magnetic resonance imaging (mri) and color doppler ultrasonography parameters in the diagnosis and differenti...

Metastasis from breast cancer to other parts of the body is very common, but the spread of the tumor to pituitary gland, especially to infandibulum, is a rare presentation. At the time of pituitary metastasis, a majority of the patients have clinical and radiological evidence of the disease. It seems that the posterior area of the gland is the most common site of metastasis, probably due to hig...

the brain is a rare site for metastasis in most extracranial pediatric solid tumors, including wilm’s tumor. outcome for these patients are generally dismal. very few cases have been reported to have good survival even after therapy. this paper reports a case of stage iv wilm’s tumor with lung metastases in a patient who developed a solitary brain metastasis five months after completion of chem...

inflammatory myofibroblastic tumor (imt) is a rare neoplastic lesion with tendency toward local aggressive behavior and recurrence. the tumor most commonly occurs in the pulmonary system of children and young adult, although it may rarely develop in older patients and other organs. symptoms are non-specific and depend on the location of the tumor. the gastrointestinal tract is rarely the primar...
