Introduction: To explore diagnostic potential of computerize texture analysis methods in discrimination of the normal, benign and malignant ovarian lesions by CT scan imaging.   Materials and Methods: Ovarian CT image database consists of 10 normal, 10 benign and 3 malignant which were reported by radiologist and proven by clinical examinat...

Neuroendocrine tumours (NET) of the lung are divided in subtypes with different malignant potential. The first is the benign or low-grade malignant tumours, well-differentiated, called typical carcinoids (TC) and the second is the high-grade malignant tumours, poorly differentiated of small (SCLC) or large cell type (LCLC). Between these tumour types lies the well-differentiated carcinoma with ...

OBJECTIVE The incidence of gastric polyps (GPs) greatly differs according to study populations and was found to be 0.33%-6.7% in various studies. The majority of GPs are composed of hyperplastic polyps (HPs), fundic gland polyps (FGPs), and adenomatous polyps (APs). Although APs have a high risk of malignant potential, sporadic FGPs have no malignant potential. Conversely, HPs have a low risk o...

Dysembryoplastic neuroepithelial tumor is a relatively recently recognized neuropathological entity that was first proposed in 1988. It is typically considered either a quasi-hamartomatous lesion or a benign, low-grade mixed glioneuronal tumor, and is of World Health Organization grade I classification. Earlier studies suggested the clinical stability of this entity given the predominant lack o...

Brunner's gland hamartomas are rare tumours of the duodenum. These lesions have previously been described as being benign, with no malignant potential. A case report is presented of a Brunner's gland hamartoma, whose histology revealed a focus of well marked epithelial dysplasia. This case suggests a dysplastic stage in the natural history of Brunner's gland hamartoma, and questions the maligna...

We present the case of 10-year-old girl who have had from birth a plane tumor, of tan color, 3-4 mm of diameter, localized on the face on the cutaneous part of the superior lip. This tumor has been stabile until 8-year-old. Then, after repeated sunlight exposures, the lesion has become more stark, hemispheric in shape, has increased in size becoming about 5-6 mm, with irregular borders, and aft...

A 49-year-old female with history of uterine leiomyoma and intermittent shortness of breath presented to the emergency department with new onset of tachycardia and chest pain. Subsequent cardiac work up revealed hypoechoic mass compressing the right ventricle. Computer tomography guided biopsy for tissue characterization revealed a benign spindle cell tumor. Surgical resection of a large epicar...

BACKGROUND MicroRNA (miRNA) expression profiles have been described in pancreatic ductal adenocarcinoma (PDAC), but these have not been compared with pre-malignant pancreatic tumors. We wished to compare the miRNA expression signatures in pancreatic benign cystic tumors (BCT) of low and high malignant potential with PDAC, in order to identify miRNAs deregulated during PDAC development. The mech...

This paper presents an approach for automatically identifying high-level narrative structure information, particularly character roles, from unannotated folk tales. We introduce a new representation called action matrices to encode Propp’s narrative theory on character role and their “sphere of action.” We tested our approach in a fully automated system (Voz) using a corpus of 10 folk tales. Ou...
