Here, we present case xanthogranulomatous osteomyelitis tibia 43 years old patient, which rare pathological entity and possibly was reported first 1984. The histopathological sections revealed dense lympho-plasmacytic infiltrate the marrow s...

Upper palpebral conjunctival biopsy specimens obtained from eight patients with active trachoma were examined by routine histological and immunohistochemical methods. The epithelium expressed class I major histocompatibility complex (MHC) products throughout and class II MHC products in the superficial layers. The epithelial inflammatory infiltrate consisted of polymorphonuclear leucocytes, mac...

Chronic rhinosinusitis (CRS) is a heterogeneous disease. Possibilities for subclassification exist via the phenotype and by endotyping based on inflammatory infiltrate in local tissue. As an interesting component of innate immune defense, cytotoxic cytokine-producing natural killer cells (NK) as tissue-based can have direct influence pathogenesis. Thus, aim this work was precise characterizatio...

The aim of this study was to evaluate the prevalence of periapical cysts, identify their clinical and microscopic features and correlate their microscopic features with the inflammatory infiltrate present in the lesion site. A total of 214 cases were collected over a 10-year period. Clinical data, including gender, age, race, symptoms and location of the lesion, were recorded. Two independent e...

OBJECTIVE The objective of the present study was to verify the hypothesis that no difference in biocompatibility exists between different orthodontic adhesives.
