AbstractIntroduction: Hyperplastic polyps of the esophago-gastric junction are seen during endoscopic evaluation of upper gastrointestinal tract. They are usually asymptomatic and discovered accidentally during endoscopic evaluation for other problems. These protrusions are mucosal regenerative response to surrounding mucosal injury. Case: Here we present a 9-year-old boy presenting with abdomi...

Oral papilloma is a benign tumourous lesion. Part of this lesion is associated with human papillomavirus (HPV) infection. We analysed the genetical and histopathological evidence for HPV type 2 infection in three oral papillomas. Southern blot hybridization showed HPV 2a sequence in one lesion. Cells of the positive specimen appeared to contain high copy numbers of the viral DNA in an episomal ...

Palisaded encapsulated neuroma (PEN; solitary circumscribed neuroma) is a benign and hyperplastic lesion consisting of Schwann cells. PEN of the lower lip was reported by Tomich and Moll [1] 35 years ago. However, the accumulation of the information about PEN which occurred in the oral mucosa was not enough. This article describes a case of a PEN on the upper lip of a 41-year-old woman. The les...

OBJECTIVE Vascular tumors of the conjunctiva in the horse are rare. We present a unique case of an intravascular papillary endothelial hyperplasia of the conjunctiva. ANIMAL STUDIED Horse. PROCEDURES Case report. A 6-year-old-mare presented with a red mass in the conjunctiva of the left eye. After complete ophthalmologic examination the lesion was excised. The tissue was processed for light...

The peripheral giant cell granuloma (PGCG) is a benign inflammatory hyperplastic type of lesion of unknown etiology occurring in gingiva or alveolar ridge. It normally presents as a soft tissue purplish-red nodule consisting of multinucleated giant cells in a background of mononuclear stromal cells and extravasated red blood cells. A 75 years old male patient reported with a chief complaint of ...

A 23-year-old Caucasian male with Neurofibromatosis Type I (NF-I) was found to have a submucosal nodule at the gastroesophageal junction (GEJ) and underwent endoscopic submucosal dissection. Histological examination revealed two different lesions within the nodule. The dominant lesion was inflammatory/hyperplastic (juvenile-like) polyp with obliterative vasculopathy while the smaller lesion was...

Acral lentiginous melanoma (ALM) is the most common type of cutaneous melanoma in Asians. The very early stage of ALM demonstrates only a proliferation of a few atypical melanocytes within the epidermis, and has been termed ALM in situ. A 74-year-old male patient presented with a pigmented lesion on the left great toe for 12 years, which had initially showed only a few scattered hyperplastic at...

Traditional serrated adenoma (TSA) is a type of serrated polyp of the colorectum and is thought to be a precancerous lesion. There are three types of serrated polyps, namely, hyperplastic polyps, sessile serrated adenomas/polyps, and TSAs. TSA is the least common of the three types and accounts for about 5% of serrated polyps. Here we report a pediatric case of TSA that was successfully resecte...

a 37-year-old woman underwent surgery to remove bilateral vulvar masses. the masses were firm, non-tender, and immobile. pathologic finding was a well-delineated creamy grayish mass with a homogenous grayish solid surface and mild edema, chronic inflammatory infiltration, and focal dilation of the ducts with squamous metaplasia. the diagnosis was hyperplastic and hypertrophied bartholin’s gland...

A 24-year-old woman presented with a history of chronic watery diarrhea associated to abdominal pain and weight loss. Her father had died of cirrhosis at the age of 47 and her grandmother had died from colorectal cancer at the age of 69. A colonoscopy revealed multiple sessile polyps scattered throughout the colon (ranging from 3 to 15mm), and a large, villous looking lesion located in the asce...
