Background: Neurofollicular hamartoma (NFH) is characterized histopathologically by fascicles of spindle cells that laterally delimited by hyperplastic folliculosebaceous units. It usually appears on face, near the nose or nasolabial fold. It does not manifest true neural differentiation and recently the term spindle cell predominant trichodiscoma (SCPT) has been used instead. Case Presentatio...

Early and accurate diagnosis of brain tumors, a lethal disease caused by the abnormal growth cells in brain, is imperative to increase survival rates. A popular method for detection, diagnosis, treatment magnetic reasoning imaging (MRI) because it non-invasive provides high-quality visuals. Unfortunately, analyzing them manually can often be time-consuming requires medical expertise. Image clas...

primitive  neuroectodermal  tumor  (pnet)  of  kidney  is  an  extremely  rare  renal  neoplasm  with only about fifty reported cases in literature.  presumably,of neural crest origin, these tumors behave  aggressively  and  carry  a  poor prognosis.  we  report  a  case  of  22-year  old  female  patient complaining of left loin pain with recurrent hematuria for last 3 months. on clinical exam...

Primitive non-neural granular-cell tumor (PNGCT) is a rare tumor of uncertain lineage. It was first described by Le Boit et al. [1] as “primitive polypoid granular cell tumor” after analysis of four cases. Since then various other names have been proposed. Lazar et al. called it “primitive non-neural granular cell tumor” [2] and Chaudhry et al. coined the term “dermal non-neural granular cell t...

Osteoid osteoma is a small tumor of bone which affect spine in 10% of cases. The tumor has tendency to neural arc and the lumbar spine is most common site of presentation. Lesions of odontoid process are very rare. We present a 20-year-old man who had cervical pain for 8 month. The pain respond to medical therapy. After investigation there was a lytic lesion at the odontoid process with charact...

background : the aim of this study was to predict the survival rate of iranian gastric cancer patients using the cox proportional hazard and artificial neural network models as well as comparing the ability of these approaches in predicting the survival of these patients. methods: in this historical cohort study, the data gathered from 436 registered gastric cancer patients who have had surgery...
