Congenital CMV chorionitis
PCR diagnosis from FFPE
Because diagnosis of congenital CMV requires viral detection within an infant’s first 21 days of life, CMV polymerase chain reaction (PCR) on formalin-fixed, paraffin-embedded (FFPE) placental tissue provides a unique opportunity to identify congenital exposure in cases in which CMV is not initially suspected.
The confirmation of CMV exposure in utero by PCR of FFPE placental tissue provides a useful adjunct to histologic evaluation and may identify infants requiring close clinical follow-up.
