Cell population (2) – lymphoid cell Larger cell size (2-4 times) Irregular nuclear membrane Nuclear protrusion, cleaved Dense and multiple nucleoli Relatively scanty cytoplasm Hand mirror cells Karyorrhexis Abnormal mitoses
Inflammatory reaction ? Lymphocyte Small Mature Polyclonal “Nuclear protrusion” Never observed in normal lymphocytes “abnormal mitoses” Considered as a landmark of cancer
Diagnosis Atypical lymphoid cells, mixed with reactive histiocytes, suggesting lymphoproliferative and hematologic malignancy
Acute blastic leukemia Lymphoma Cell size Larger cell size 2-4 times Large cells with variable size Cytoplasm Thin rim Transparent Relatively scanty (Some may be abundant) Nuclei Nuclear protrusion (Hypersegmentation) Spherical, oval Irregular contour Nucleoli Large Pink nuclear inclusion (empty space) Large, multiple Hand mirror cell Present May be present Other Mitotic activity (abnormal mitoses) Karyorrhexis: particularly common in lymphoma
