Inverted hyperplastic polyps (IHPs) of the colon are unusual variant of exophytic hyperplastic polyps that are characterized by epithelial displacement or inversion of the epithelium into the submucosa. To date, only a few cases of IHPs associated with adenoma or adenocarcinoma have been reported. However, due to the rarity of these polyps, their malignant potential is poorly understood. A 56-y...
The patient, a 40-year-old male, was referred to our clinic with intermittent nausea, vomiting and symptomatic anemia for 4 months. Notable hematological indices were low hemoglobin levels of 9.6 g/dl and hematocrit levels of 35.8%, while after receiving two units of concentrated red blood cells, at discharge; they achieved levels of 15.2 g/dl and 42.3%, respectively. Esophagogastroduodenoscopy...
Background The serrated pathway to colorectal cancer is associated with a CpG-island methylator-phenotype (CIMP) and is distinct of the classical adenoma-to-carcinoma sequence. There is increasing evidence that a subset of hyperplastic polyps (HPs) serves as intermediates in an oncogenic sequence resulting in a CIMP colorectal cancer. This study analyzes molecular changes in large HPs to define...
Chronic hyperplastic pulpitis (pulp polyps) usually occurs in molar teeth of children and young adults and is characterized by an overgrowth of granulomatous tissue into the carious cavity. Here, we report a rare type of pulp polyp in lower third molar of a 27-year-old woman that not only grow into carious cavity but also extruded in very large size that interfered with occluding of the teeth.
