Adequacy score. (A): inadequate specimen (exclusively blood sample devoid of epithelial cellularity). (B): low cellularity (a small aggregate of epithelial cells in blood sample). (C): moderate cellularity (a clearly visible cellular cluster with preserved architecture, without atypia). (D): rich cellularity (cellular neoplastic clusters with atypical hyperchromic nuclei, punctiform necrosis, and apoptotic bodies).
