The aim of the present study was to assess the clinico-histopathological picture and to examine the recurrence of various localized hyperplastic gingival growths after their surgical treatment. Twenty patients of localized hyperplastic gingival outgrowth were evaluated in the present clinico-histopathological study. The data regarding age, sex, location, size, and duration of lesion were summar...

The purpose of this study was to determine the prevalence of pancreatic nodular hyperplasia (NH) and its relation to age in the dog. A total of 101 dogs were enrolled. The pancreas was evaluated by histology and hyperplastic lesions were detected and scored. Age was recorded from the medical records. Correlation of age with inflammation and presence of hyperplastic lesions was evaluated. Of the...

Dermatofibroma (DF) is usually confined to the dermis and the overlying epidermis is usually hyperplastic. Although DF with deep subcutaneous extension is commonly encountered, purely subcutaneous DF is uncommon. In this review, we describe a case of a 41-year-old male patient who presented with a painless, subcutaneous, hard papule on the left thigh. After the skin had been incised the lesion ...

Background Hyperplastic polyps (HP) and sessile serrated adenomas (SSA) share morphological similarities. In this immunohistochemical study we chose a panel of potential relevant and promising biomarkers including α-methylacyl-coenzyme A racemase (AMACR;p504s) , which is involved in the degradation of branched chained fatty acids derivates, and analysed a cohort of HPs and SSAs in order to iden...

The morphology of hyperplastic pituitaries in seven human growth hormone-releasing factor (hGRF) transgenic mice were compared to those of two normal control mice. Under continuous stimulation by hGRF, both the total volume of the pituitary and the size of individual cells increased, and a nodular lesion, designated a "hypertrophic nodule", was identified. Immunohistochemically, the hyperplasti...

BACKGROUND Ecthyma gangrenosum is an infective lesion of the skin and mucosal membranes. It is most commonly caused by Pseudomonas aeruginosa, and the most important risk factors are malignancy and neutropenia. However, it has rarely been reported in children who were previously healthy. Persistent hyperplastic primary vitreous has been described as the persistence of the fetal hyaloid vascular...

Angiolymphoid hyperplasia with eosinophilia is a rare, benign vascular tumor affecting principally the head and neck region of young adult females. Microscopic analysis reveals hyperplastic blood vessels lined by a hypertrophic endothelium. An inflammatory infiltrate rich in eosinophils is also present. Etiology of the lesion is unknown. Various treatment modalities have been described. We pres...

Gastritis cystica profunda (GCP) is a rare hyperplastic lesion of unclear etiology. Clinical symptoms of GCP are variable and range from nonspeci ic abdominal pain to gastric outlet obstruction. Often the diagnosis of GCP has been dif icult to make as simple esophagogastroduodenoscopy (EGD) guided biopsy can fail to yield the diagnosis. Here, we report a case of GCP that presented in a challeng...

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...
