congenital granular cell tumor (gct) is a relatively rare intraoral benign tumor, approximately 200 cases of which have been reported in the neonatal period worldwide. the newborn infant may have feeding problems and respiratory difficulties due to airway obstruction. this lesion may be diagnosed by prenatal ultrasonography and simple resection is mostly required. we report a case of an adult t...

carcinoid tumor is a slow-growing type of neuroendocrine tumor, originating in the enterochromaffin cells and secreting mainly serotonin. the diagnosis is based on clinical symptoms, hormone levels, radiological and nuclear imaging, and histological confirmation. the clinical symptoms are characterized by flushing, diarrhea, abdominal pain, telangiectasia and/or bronchoconstriction. however, mo...

desmoid tumor of breast is a rare benign, locally aggressive tumor with a high recurrence rate. it has been associated with scar from previous breast surgery or trauma. especially in breast cancer patients with previous operation history, it may simulate recurrent breast cancer clinically and radiologically. we presented multimodality imaging findings (ultrasound, computed tomography, magnetic ...

Cells grow and then need a very neat method to create new cells that work properly to maintain the health of the body. When the ability to control the growth of the cells is lost, they are unconsidered and often divided without order. Exemplified cells form a tissue mass called the tumor.

salivary diagnostics has fascinated many researcheres and has been tested as a valuable tool in the diagnosis of many systemic conditions and for drug monitoring. advances in the field of molecular biology, salivary genomics and proteomics have led to the discovery of new molecular markers for oral cancer diagnosis, therapeutics and prognosis. oral cancer is a potentially fatal disease and the ...

 Leydig stromal cell tumor is a rare ovarian tumor that belongs to the group of sex-cord stromal tumors. They produce testosterone leading to hyperandrogenism. We present a 41yr old woman with symptoms of virilization and a mass of right adenex via ultra Sonography, and a rise of total and free serum testosterone.
