Ameloblastic fibroma (AF) is a benign tumor of mixed odontogenic origin, which affects predominantly young individuals. AF appearing as a mixed radiographic image is very rare. This report describes a case of AF in a 12-year-old male identified during a routine radiographic exam for orthodontic treatment planning. The panoramic radiography revealed a well-defined multilocular mixed image locate...

background: ovarian cancer comprises a heterogeneous group of neoplasms. the prognosis cannot be predicted by histopathologic examination alone. the aim of this study is to evaluate p53, pten, and β-catenin expressions in primary ovarian carcinomas in an attempt to find a possible relationship with morphologic parameters and clinical findings. methods: the study included 100 epithelial ovarian ...

objective her-2/neu gene is overexpressed in diverse human cancers and studies suggest a role of its product – p185 protein – in tumor progression by specifically promoting the invasive capacity of tumor cells. our aim was to evaluate her-2/neu content in resectable gastric cancer in this geographical region and assess the relationship between p185 expression and clinicopathologic tumor paramet...

A carcinosarcoma is a tumor composed of cells morphologically resembling both malignant epithelial and mesenchymal components. An 11-year-old, female, mixed-breed terrier was referred to the clinic with complaints anorexia, vomiting exercise intolerance. Clinically, tumoral masses were seen in mammary glands. During necropsy, multilobulated calcified observed several visceral organs (the liver,...

BACKGROUND Diffusion-weighted imaging (DWI) is a noninvasive method for investigation of tumor histological content. It has been applied for some musculoskeletal tumors and reported to be useful. OBJECTIVES The aim of the present study was to prospectively evaluate the apparent diffusion coefficient (ADC) values of benign and malignant soft tissue tumors and to determine if ADC can help diffe...

Renal mixed tumor characterized by the absence of nephrogenic blastema and the presence of predominant osteoid-producing osteoblast-like cells occurred in the kidney of a 6-month-old, hybrid, female pig. At the post-mortem examination, the tumor was found as a calcified grayish-white mass at the cranial end of the left kidney. Histologically the tumor consisted of 3 growth areas of poorly diffe...

Malignant glioma comprises glioblastoma [World Health Organization (WHO) grade IV], anaplastic astrocytoma (WHO grade III), mixed anaplastic oligoastrocytoma (WHO grade III) and anaplastic oligodendroglioma (WHO grade III). Diagnosis after biopsy or tumor resection is made according to the revised WHO classification. Prognosis depends on tumor grade and histology. Glioblastoma carries the worst...

We have developed a multiplex reporter system to monitor multiple biological variables in real-time. The secreted Gaussia luciferase was fused to ten different epitope tags (Gluc(tag)), each expressed in different tumor cells. By immunobinding of the tags followed by Gluc(tag) detection, this system allowed the independent and real-time monitoring of mixed cell cultures in vitro and of mixed su...
