BACKGROUND: Oral lichen planus is an inflammatory chronic disease with an autimmune pathogenesis and unknown etiology that affects oral mucosa, with or without the involvement of the skin and other mucous membranes. The principal histological characteristics are the degeneration of the basal cell layer and the abnormal infiltration of inflammatory cells into the subepithelial layer of connective tissue. OBJECTIVES: This study is aimed to appraise if lingual lichen planus (LLP) is sustained by alteration of the oral microcirculation and if this abnormal vascularisation increases the degeneration of basal keratinocytes and the disruption of the basement membrane...

Crosspresentation is a specialized function of myeloid dendritic cells (mDCs), allowing them to induce CD8+ T cell responses against exogenous antigens that are not directly produced in their cytotosol. Human plasmacytoid DCs (pDCs) are not considered so far as able to perform crosspresentation. We showed here that purified human pDCs crosspresented vaccinal lipopeptides and HIV-1 antigens from apoptotic cells to specific CD8+ T lymphocytes. Apoptotic debris were internalized by phagocytosis and the lipopeptide LPPol reached nonacidic endosomes...

INTRODUCTION: Neoplasms, autimmune disorders and infectious diseases as differential diagnoses of cervical lymphadenopathies also require the consideration of rare causes. CASE REPORT: A 25-year-old patient presented for further diagnosis and treatment of a colliquating, high febrile cervical lymphadenopathy. The patient from Thailand who had been living in Germany for 8 years reported she worked as rice farmer during the 1980s.

The hemophagocytosis or the process of ingestion of blood cells by phagocytes and macrophages of the mononuclear phagocytic system (MFS), is a phenomenon that rarely could be observed in the morphological examination of the bone marrow aspirate. Occasionally it is present in certain pathologic conditions such as, malignant histiocitosis, autimmune hemolytic anemia, or some chronic inflammatory diseases. The capacity of ingestion is not an exlusive property of the phagocytes and macrophages of the MFS, so that different neoplastic cells can show it too...
