An 81-year-old woman presented for colonoscopy because of iron deficiency anemia. She had undergone colonoscopy 5 years previously during which a 2-cm prominent fold had been identified in the proximal ascending colon (●" Fig.1). A biopsy of this lesion was interpreted as being a hyperplastic polyp (●" Fig.2), although the polyp showed features of a serrated lesion. Because of clinical concern ...

 Gingiva is a common region of inflammatory and reactive lesions. Systemic conditions, including hormonal imbalance in pregnant women, may cause exaggerated response to irritations such as calculus or infection. Therefore, more accurate assessment is necessary to achieve the best decision making in the differential diagnosis and treatment of these patients. In this paper, we present a rea...

We present herein the occurrence of multifocal adenocarcinomas with a minute signet ring cell carcinoma that arose within a gastric inverted hyperplastic polyp (IHP) in a 40-year-old woman. Endoscopic ultrasonography demonstrated a heterogeneous hypoechoic mass in the third layer of the gastric wall. The endoscopic submucosal dissection specimen measuring 3.5×3.2×1.8 cm was a well-circumscribed...

Hyperplastic dental follicle is an odontogenic hamartomatous lesion associated with delayed or tooth eruption failure in young patients. The occurrence of this pericoronal dental lesion may be single or multiple and it seems to be more frequent than literature has reported. We present a literature review focusing on the etiopathogenesis and clinicopathological features of this hamartomatous les...

A pyogenic granuloma is a reactive hyperplastic inflammatory lesion that arises as result of various stimuli such low-grade local irritation, trauma, hormones, and certain medications. In the oral cavity, it relatively common gingival soft tissue lesion, which originates an expansile growth mucous membrane. It could exhibit aggressive behaviour mimicking malignant lesions with different present...

Gastric hyperplastic polyps are often asymptomatic and are found incidentally at upper endoscopy performed for unrelated reasons. Although they are considered a benign lesion, all symptomatic polyps should be removed for a more reliable histological diagnosis, resolution of symptoms and to prevent potential malignant transformation. In fact, there are no significant difference between pure gast...

Gastritis cystica polyposis (GCP) is a rare benign hyperplastic polypoid neoplasm that usually occurs on the gastric side of anastomoses in patients who have previously undergone gastroenterostomy surgery. Only few cases GCP been reported unoperated stomach. Here we present 73-year-old female investigation for altered bowel habits was found to polyp diagnosed as GCP. Both endoscopic and radiolo...

The study searched for epidermal growth factor receptor (EGFR) gene amplification in hyperplastic glottis lesions. After classical pathohistological findings of hematoxylin-eosin (HE) slides and quantitative immunohistochemical (IHC) analysis, fluorescent in situ hybridization (FISH) was used on tissue microarrays of laryngeal hyperplastic tissue ranging from normal mucosa to abnormal and atypi...
