CONTEXT Localized reactive lymphoid hyperplasia is a rare condition characterized by the presence of lymphoid follicles. CASE REPORT We describe a case of a 60-year-old woman who presented with right upper quadrant pain and was found to have a reactive nodular hyperplasia of the pancreas involving the uncinate process, body and tail of the gland. Due to the multifocal distribution of these hy...

INTRODUCTION Reactive lymphoid hyperplasia is a benign nodular lesion characterized by marked proliferation of non-neoplastic, polyclonal lymphocytes forming follicles. The lesion is found in various organs such as skin, orbit, lung, gastrointestinal tract, and liver. However, reactive lymphoid hyperplasia in the thyroid gland is extremely rare. Here, we present an interesting case of reactive ...

Aim: To establish standard for diagnosis of reactive follicular hyperplasia of lymph node. Methods: This study was conducted at the Department of Pathology, Benazir Bhutto Shaheed College Mirpur, Govt of AJK. 50 cases of reactive follicular hyperplasia were included in the study. Five micron thick, paraffin embedded sections were stained with H & E and reticulin stain. Results: The median numbe...

Background: Gingival overgrowth is a common clinical finding that most often represents reactive hyperplasia as a result of inflammatory gingival disease related to dental plaque. Irritation fibroma (IF), pyogenic granuloma (PG), peripheral ossifying fibroma (POF), and peripheral giant cell granuloma (PGCG) are non-neoplastic enlargements of the gingiva that are categorized as reactive hyperpla...

mens from patients with Hodgkin's disease and five specimens from patients with reactive follicular hyperplasia. The use of chlorazol fast pink BK, a little known stain for eosinophil polymorphs, combined with image analysis facilitated rapid and reliable counting. Significant differences were found between the mean percentages of eosinophil polymorphs in the Rye subtypes of Hodgkin's disease. ...

Argyrophilic nucleolar organiser regions (AgNORs) in 28 follicular lymphomas and 30 lymph nodes showing reactive follicular hyperplasia were studied to see if they were helpful in distinguishing follicular lymphoma from follicular hyperplasia in paraffin wax tissue sections. Mean nuclear counts were greater in follicular hyperplasia (3.71 v 3.11). This difference was significant but counts over...

Subpontic osseous hyperplasia is a relatively uncommon benign submucosal mass of normal bone found beneath a pontic. Three cases of mandibular subpontic osseous hyperplasia are described, adding to the 40 existing cases in the English-language literature. Subpontic osseous hyperplasia may represent a unique reactive osseous metaplasia in the subpontic region, with chronic stimuli and functional...
