Abstract Background Patients with COVID-19 (COVID) may develop acute respiratory distress syndrome or without sepsis, coagulopathy and visceral damage. While chest CT scans are routinely performed in the initial assessment of patients severe pulmonary forms, thymus involvement reactivation have not been investigated so far. Methods In this observational study, we systematically scored enlargeme...

Paraffin sections from a series of 50 lymph nodes affected by Hodgkin's disease were examined by means of the unlabelled primary antibody peroxidase-antiperoxidase method to detect those cells which contained S-100 protein. In addition, 15 lymph nodes showing reactive follicular hyperplasia were studied. A simple enumeration procedure (eyepiece graticule) was used to count the number of such ce...

PURPOSE To report the clinicopathologic features and management of patients with benign reactive lymphoid hyperplasia of the caruncle and plica semilunaris. METHODS This retrospective case series includes 5 patients with lesions in the caruncle or plica semilunaris who underwent surgical excision over a 10-year period. The clinicopathologic features and immunohistochemical studies are reporte...

a variety of verrucous and papillary lesions affect the oral mucosa. Those which are benign and reactive, for example squamous papilloma or verruciform xanthoma, usually present little diagnostic difficulty. However, dysplastic and malignant verrucous and papillary lesions are a much greater diagnostic challenge, not helped by confusing terminology. papillary hyperplasia is a reactive inflammat...

There are some reports, suggesting that infiltrating macrophages may promote tumour progression in non-Hodgkin's lymphoma (nHL). The aim of the study was an evaluation of macrophages, marked by antibody against CD68 in indolent and aggressive nHL. The study was performed in 65 patients: 50 with nHL and 15 with lymph nodes affected by reactive hyperplasia. Immunohistochemical analyses were perfo...

Isolated soft tissue enlargements seen in the oral cavity are generally a reactive hyperplasia and rarely neoplastic. Irritation fibroma is a benign tumor of fibrous connective tissue that can be considered a reactionary connective tissue hyperplasia in response to trauma and irritation. It is a gingival lesion of reactive nature with unknown etiology. As the lesion occurs due to continuous tra...

DIAGNOSIS AND STAGING – DOGS The typical dog with LSA will present with generalized (or less commonly regional) lymphadenopathy. Differential diagnoses for generalized adenopathy can include Ehrlichiosis or other immune-mediated diseases, systemic mycosis, severe pyoderma or other skin disease, and reactive hyperplasia. The most simple way do discern the cause for lymphadenopathy is via needle ...

Abstract: Hemangioma of the thyroid gland is a rare diagnosis and less than 35 cases have been previously published in literature. The pathogenesis unknown but it suggested to be developmental anomaly which associated with an incapability angioblastic mesenchyma form canals. On microscopic examination, should distinguished from reactive endothelial hyperplasia, angiosarcoma or hemangiosarcoma. ...

INTRODUCTION AND OBJECTIVES C-reactive protein (CRP) is an inflammatory marker that predicts cardiac events in patients with coronary syndromes. However, data on the relationship between the CRP level and in-stent restenosis are contradictory. The objective of this study was to investigate the relationship between the basal CRP level and the neointimal hyperplasia volume measured by intracorona...
