ABSTRACT
Urinalysis in a pediatric patient with oliguria and cervical lymphadenopathy: role of automated imageanalysis systems.
Automated urinalysis instruments image-based for cell analysis can identify non-squamousepithelial cells (NSE). Among these elements, expert pathologists can distinguish the so called Decoy Cells (DC),Polyomavirus BK (BKV)-infected elements primarily seen in immunocompromised patients. Epstein-Barr virus (EBV)infection can induce a transient immunosuppression in immunocompetent patients, and this could lead to areactivation of a latent BKV infection in urothelial cells: this is a rare event in pediatric patients. This study reports thecase of a 4 year-old child with lateral lymphadenopathy, fever and oliguria. Automated urinary sediment analysisevidenced the presence of many NSEs identifed as DC, generating a subsequent virological investigation with a finaldiagnosis of concomitant BKV and EBV infection. The combination of an automated technology, an efficientmiddleware and the expertise of the laboratory professionals , allowed the proper identification of these peculiarreactive elements, which could easily be mistaken for malignant atypical cells.
