Distinct Molecular Features of Different Macroscopic Subtypes of Colorectal Neoplasms
BACKGROUND Colorectal adenoma develops into cancer with the accumulation of genetic and epigenetic changes. We studied the underlying molecular and clinicopathological features to better understand the heterogeneity of colorectal neoplasms (CRNs). METHODS We evaluated both genetic (mutations of KRAS, BRAF, TP53, and PIK3CA, and microsatellite instability [MSI]) and epigenetic (methylation sta...
متن کاملPossible mechanism connected with the progression of submucosal invasion in colorectal neoplasias.
Previous studies in human and in experimentally-induced colorectal carcinomas showed that the material retained in dilated glands at the growing tumour edge was directly released into the peritumoral extracellular matrix (ECM) through glandular faults called glandular pores. In this work, the characteristics of the glands at the growing edge in adenomas with submucosal invasion were investigate...

متن کاملClinicopathological Features of Contagious Ecthyma-Like Lesions in a Dog
Background: Contagious ecthyma or orf is a poxviral disease of goat and sheep, with incidental infection appearing in humans, cows, camels, and many wild ruminants, and very rarely in dogs. Case description: In the present paper was described gross morphology and histopathology of contagious ecthyma in a dog with a large ulcerated cutaneous mass in the neck (under the collar) which was ma...
متن کاملSubmucosal pocket-assisted enucleation of gastric submucosal lesions
Identifying and resecting gastric submucosal lesions through submucosal tunneling is not always easy, because of difficulties in orientation or a lack of sufficient working space. This article presents the resection of two gastric lipomas with a modified pocket-creation method (Fig. 1), initially scheduled for endoscopic submucosal dissection (ESD) of epithelial lesions [1]. A 63-year-old male ...
