Background The influence of cutaneous cellular infiltration on the phenotype bullous pemphigoid (BP) remains to be established. Objectives To evaluate main histopathological characteristics patients with BP and assess association between composition lesional inflammatory infiltrate various clinical, immunological immunopathological aspects disease. Methods Retrospective study encompassing diagn...

Several immune-related markers have been implicated in basal cell carcinoma (BCC) pathogenesis. The BCC inflammatory infiltrate is dominated by Th2 cytokines, suggesting a specific state of immunosuppression. In contrast, regressing BCC are characterized by a Th1 immune response with IFN-γ promoting a tumor suppressive activity. IL-23/Th17-related cytokines, as interleukin (IL)-17, IL-23 and IL...

OBJECTIVE To describe a series of 41 patients with fresh lesions of Sweet syndrome in which the histopathologic study demonstrated an inflammatory infiltrate mostly composed of histiocytoid mononuclear cells. DESIGN Histopathologic, immunohistochemical, and cytogenetic studies of the inflammatory infiltrate in a case series of histiocytoid Sweet syndrome. SETTING University departments of d...

BACKGROUND The Calcium Hydroxide has been widely used as an intracanal dressing and in combination with restorative and endodontic materials and its main goal is the tissue reparation. However, when the patient has chronic stress, the immunological response and tissue repair decreases in both the epithelial and connective tissue. Therefore, the aim was to analyze the effect of chronic stress on...

The presence and distribution of lymphatic vessels and mast cells in the gingiva under normal and pathological conditions have been reported by several studies, but the relationship between them during inflammatory lymphangiogenesis is virtually unknown. The aim of the present study was to investigate the lymphatic microvessel density (LMVD) and mast cell density (MCD) in the gingiva of patient...

introduction: oral lichen planus (olp) and oral lichenoid lesions (olls) are clinically and histopathologically similar lesions but with different etiologies and treatment plan, thus differentiatingthese two has been the center of many researches. studies in different populations have beenperformed on clinical and histopathologic features of olp and olls. thus aim of the present studywas to eva...

AIM To characterise the number and nature of the inflammatory cells seen in cases of septic or aseptic loosening of hip arthroplasty, and to establish reliable histological criteria to distinguish between these two conditions. METHODS Histological examination of paraffin sections of periprosthetic tissues (pseudocapsule, femoral and acetabular pseudomembranes) of 523 cases of aseptic loosenin...
