BACKGROUND Colorectal cancer (CRC) is a life-threatening complication of ulcerative colitis (UC), and patients are routinely screened for the development of precancerous lesions (dysplasia). However, rates of CRC development in patients with confirmed low-grade dysplasia vary widely between studies, suggesting a large degree of heterogeneity between these lesions that is not detectable macrosco...
Gastric epithelial dysplasia (GED) represents a recognized precursor lesion of gastric adenocarcinoma. GED types can be classified according to its morphology and patterns of mucin expression into adenomatous (intestinal), foveolar (gastric) and hybrid (mixed) types. We examined gastroscopic specimens with GED in 35 patients (21 men and 14 women, mean age 69.6 years). Adenomatous dysplasia was ...
Actinic cheilitis is an oral potentially malignant disorder caused by UV radiation leading to damage epithelial keratinocytes of the lips. It predominantly affects vermillion border lower lip. Due its association with chronic exposure, associated risk factors include geographic areas, outdoor occupations, and skin subtypes. A high proportion lip squamous cell carcinomas arise from actinic lesio...
A cutaneous horn is a hard cone-shaped protrusion consisting of dense keratin resembling animal horns, which occurs due to abnormalities in the spinous layer epidermis, causing excess accumulation. This disease can be found any body part, especially regions exposed lot sunlight, such as ears. Surgical excision treatment choice for this disease. One case was reported male patient aged 75 years w...
We have developed a new computer-aided diagnostic system for differentiating oral borderline malignancies in hematoxylin-eosin stained microscopic images. Epithelial dysplasia and carcinoma in-situ (CIS) of oral mucosa are two different borderline grades similar to each other, and it is difficult to distinguish between them. A new image processing and analysis method has been applied to a varie...
The bone morphogenetic proteins, (BMP)s are regulatory peptides that have significant effects on the growth and differentiation of gastrointestinal tissues. In addition, the BMPs have been shown to exert anti-inflammatory actions in the gut and to negatively regulate the growth of gastric neoplasms. The role of BMP signaling in the regulation of gastric metaplasia, dysplasia and neoplasia has b...
