Descripción General

Definición

La linfadenopatía es el aumento de tamaño de los LOS Neisseria ganglios linfáticos, por lo general > 1 cm. Se considera localizada si el agrandamiento se limita a los LOS Neisseria ganglios linfáticos de 1 región anatómica y generalizada cuando hay afectación de ≥ 2 regiones.

Etiología

Muy a menudo, la linfadenopatía es una reacción a una infección local. Con menos frecuencia, puede deberse a un proceso maligno o a una enfermedad sistémica crónica. Las siguientes condiciones incluyen linfadenopatía en EN Erythema nodosum is an immune-mediated panniculitis (inflammation of the subcutaneous fat) caused by a type IV (delayed-type) hypersensitivity reaction.

  • Infecciosas:
    • Infecciones virales:
      • EBV EBV Epstein-barr virus (EBV) is a linear, double-stranded DNA virus belonging to the herpesviridae family. This highly prevalent virus is mostly transmitted through contact with oropharyngeal secretions from an infected individual. The virus can infect epithelial cells and B lymphocytes, where it can undergo lytic replication or latency. Epstein-Barr Virus ( Virus Virus Viruses are infectious, obligate intracellular parasites composed of a nucleic acid core surrounded by a protein capsid. Viruses can be either naked (non-enveloped) or enveloped.

Streptococci are identified as different species on blood agar on the basis of their hemolytic pattern and sensitivity to optochin and bacitracin. There are many pathogenic species of streptococci, including S. pyogenes, S. agalactiae, S. pneumoniae, and the viridans streptococci. Streptococcus pyogenes
