FIG. 11.55. Pharyngitis in infectious mononucleosis. This girl has inflamed, bilaterally swollen tonsils with a diffuse exudate, as is often seen with infectious mononucleosis.

Role of Epstein-Barr virus (EBV) in infectious mononucleosis, nasopharyngeal carcinoma, and Burkitt lymphoma. EBV invades and replicates within the salivary glands or pharyngeal epithelium, and is shed into the saliva and respiratory secretions. In some people, the virus transforms pharyngeal epithelial cells, leading to nasopharyngeal carcinoma. In people who are not immune from childhood exposure, EBV causes infectious mononucleosis. EBV infects B lymphocytes, which undergo polyclonal act...

FIG. 6.2. Eczema herpeticum. Ulcers and excoriations, as in these two cases [patient 1 (A, B), patient 2 (C)], usually characterize the eruption, although vesicles may be seen at times (D). More severe cases [patient 3 (E), patient 4 (F, G), patient 5 (H)], with generalized eruptions, require intravenous therapy with acyclovir.
