Early morphologic diagnosis of herpes simplex virus encephalitis: advantages of electron microscopy and immunoperoxidase staining. 1983

C L White, and J B Taxy

The authors compared three morphologic techniques that can be used in the diagnosis of herpes simplex virus encephalitis. The pathologic material was derived from brain biopsy, autopsy, or both in ten culture-proven cases. On conventional light microscopic examination, typical intranuclear Cowdry type A inclusions were recorded as absent (one case), rare (six cases), or numerous (three cases). Electron microscopic evaluation, performed in nine cases, revealed intranuclear viral particles in five biopsy and two autopsy cases, including four cases in which inclusions were rare or absent on light microscopy. In one biopsy specimen, unequivocal virus particles could not be identified ultrastructurally, although they were present in subsequent autopsy material. Immunoperoxidase staining using the peroxidase-antiperoxidase (PAP) method and type-specific anti-herpes simplex type 1 antiserum, performed on paraffin-embedded tissue, demonstrated strongly positive specific immunoreactivity in all ten cases. The potential for rapid specimen preparation, the relative sensitivity of electron microscopy, and the extreme sensitivity and specificity of the PAP-immunoperoxidase method offer obvious advantages in the early morphologic diagnosis of herpes simplex virus encephalitis.

D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D004660	Encephalitis	Inflammation of the BRAIN due to infection, autoimmune processes, toxins, and other conditions. Viral infections (see ENCEPHALITIS, VIRAL) are a relatively frequent cause of this condition.

D006561	Herpes Simplex	A group of acute infections caused by herpes simplex virus type 1 or type 2 that is characterized by the development of one or more small fluid-filled vesicles with a raised erythematous base on the skin or mucous membrane. It occurs as a primary infection or recurs due to a reactivation of a latent infection. (Dorland, 27th ed.)	Herpes Simplex Virus Infection
