“…This prospective analysis included 791 samples from PCPD using CD38, CD138, CD45, CD19, CD56, CD27, CD81, CD117, Cy-kappa, and Cy-lambda markers. The role played by these immunological markers in discriminating normal and aberrant plasma cells (NPC and APC, respectively) has been discussed, providing further insights into plasma cell characterization through the artificial eyes of flow cytometry (Das et al, 2022;Jevremovic & Olteanu, 2019;Mestrum et al, 2020;Oliveira et al, 2019;Zannetti et al, 2020;Zannetti et al, 2021). Based on these findings, authors have concluded that CD200 is commonly expressed on circulating Sezary cells, a feature that can potentially improve the diagnostic capacity of flow cytometry for the assessment of T-cell neoplasms (Guitart, 2020;Horna et al, 2020;Lyapichev et al, 2020;Shameli & Roshan, 2022).…”
