background and aims. reactive hyperplasias (rhs) are common oral mucosal lesions caused by irritation of the mu-cosa. the aim of this study was to evaluate the frequencies of various types of oral rhs in a university clinic. materials and methods. oral rh cases, undergone biopsy in a four-year period, were studied retrospectively. data including age and gender as well as the location and clinic...

purpose: to report five cases of benign reactive lymphoid hyperplasia of the caruncle and plica and describe their clinical course and pathology. case report: five patients with fish flesh pinkish masses in the caruncle and plica were referred to labbafinejad hospital from 1997 to 2006. the masses were excised. clinical appearance and course as well as pathology and immunohistochemistry confirm...

Background: Reactive lymph node hyperplasia can exhibit morphological patterns I to VI. This study was done evaluate hyperplasia, reactive patterns, metastasis and correlation with tumour stage, size. Methods: Total 454 nodes were reviewed for metastases reactivity VI as per the World Health Organization (WHO) protocol. Association between qualitative variables assessed by chi-square test Fishe...

background: the aim of this study was to quantify the number of mast cells in focal reactive hyperplastic lesions of the oral cavity and to compare these two number of mast cells in normal gingival tissues and to correlate their presence with the state of connective tissue changes in reactive lesions and probably suggest a role for mast cells in these lesions. materials and methods: patient rec...

background: reactive lesions of the oral cavity are non-neoplastic proliferations with very similar clinical appearance to benign neoplastic proliferation. this similarity is troublesome in the differential diagnosis. the aim of this study was to determine the frequency and distribution of oral cavity reactive lesions. materials and methods: the study was a retrospective archive review. the med...

OBJECTIVE To determine the seroprevalence of Toxoplasma gondii (T. gondii) in children with reactive hyperplasia of the cervical lymph nodes. METHODS This cross-sectional prospective study was conducted in Khartoum Children Emergency Hospital, Khartoum, Sudan between January 2010 and April 2011. Eighty children with cervical lymphadenopathy were selected using random sampling. Their lymph nod...

The sizes of follicle centre cells in 15 specimens of follicular (centroblastic-centrocytic) non-Hodgkin's lymphoma and 15 specimens of reactive follicular hyperplasia have been measured. The findings differ from previous studies, where nuclei of cells from follicle centres and interfollicular areas were measured and revealed no significant difference between follicular lymphoma and reactive fo...

Reactive lymphoid hyperplasia is a rare disease that forms a mass-like lesion and is characterized by the proliferation of non-neoplastic, polyclonal lymphocytes forming follicles. We recently encountered 2 cases of reactive lymphoid hyperplasia of liver, both of which were asymptomatic and mimicked hepatocellular carcinoma by various imaging modalities. Based on the clinical impression of hepa...
