Although brain tumors have been known tremendously over the past decade, there are still many problems to be solved. The etiology of brain tumors is not well understood and the treatment remains modest. There is in great need to develop a suitable brain tumor models that faithfully mirror the etiology of human brain neoplasm and subsequently get more efficient therapeutic approaches for these d...

Serous cystic neoplasms of the pancreas are rare exocrine pancreatic neoplasms, most of which are benign and do not communicate with the pancreatic duct. Pancreatic intraepithelial neoplasm (PanIN) is considered a precursor of ductal adenocarcinoma that is microscopically recognized in pancreatic ducts. A 67-year-old Japanese woman presented with a 10-mm multilocular cystic lesion at the pancre...

Most ovarian neoplasms are benign, epithelial types are commonest. There is no regular screening test for detecting malignant ovarian neoplasm, most patients remain asymptomatic until late stages. About 80% of malignant ovarian neoplasm present in stage 3 and 4 with 15% 5 year survival rate. To find out frequency of different types of ovarian neoplasm among women aged 15-60 years and correlates...

Introduction: Chronic sclerosing sialadenitis is a relatively uncommon disorder of the salivary gland. Because of its clinical similarity to a salivary gland neoplasm, this condition has been known as Kuttner tumor and is classified as a tumorlike lesion. Case Report: This is the first reported case of bilateral Kuttner tumor of the submandibular glands in Iran. It was initially diagnosed as...

BACKGROUND Ameloblastoma is a benign odontogenic tumour that may exhibit aggressive biological behaviour with local recurrence and metastasis following initial surgical resection. Surgery is the most acceptable modality of treatment, even if a biological approach is currently on study. We report a case of maxillary ameloblastoma with development of neck and brain metastases after repeated local...

Postmortem imaging notably CT, has been embraced in medicolegal death investigation. It allows for non-invasive interrogation of the skull and cranial contents prior to autopsy, forewarning likely findings excluding overt pathology such as fractures, haemorrhage, mass lesions. There are, however, deficiencies postmortem CT part due changes brain at or after death, inherent insensitivity subtle ...

background: improvements in imaging techniques has led to an increase in the number of diagnosed pancreatic cysts. although most of the detected cases are benign, a significant percentage of them are malignant or are potentially malignant. currently, endosonography, and analysis of cyst morphology, fine needle aspiration (fna) of the cyst contents, and measurement of the amylase and carcinoembr...

  Chloroma or granulocytic sarcoma (GS) is a malignant neoplasm of myeloid lineage that occur in a variety of anatomic sites other than the bone marrow including soft tissue, bone, lymph node, nasal fossa, skin and sometime in the orbit. In the subconjunctiva it is rarely reported. A 4-year-old girl with a history of treated acute myelogenous leukemia was referred to Farabi Eye Hospital, Tehra...

Mucin Hypersecreting Intraductal Papillary Neoplasm is a rare neoplasm that arises from ductal epithelial cells. This entity is distinct from the more commonly known Mucinous Cystadenoma or Mucinous Cystadenocarcinoma. Despite this distinction, it has been erroneously categorized with these more common cystic neoplasms. Characteristic clinical presentation, radiographic, and endoscopic findings...
