[Immunological illustrations of the main B and T lymphomas (flow cytometry immunological profiles obtained from lymph node and splenic suspensions associated with characteristic morphological images)].

The diagnosis of B- and T-cell lymphomas relies on a multidisciplinary approach that combines morphological, immunological (via flow cytometry - FCM), and genetic analyses. The integration of cytological evaluation from tissue biopsy imprints with FCM enables rapid diagnostic orientation, which is valuable for guiding further complementary investigations. This atlas illustrates the main types of B- and T-cell lymphomas using cytology images, FCM data, and histological analyses derived from lymph node and splenic samples. The FCM profiles were established using routinely employed antibody panels. While results may show slight variations depending on the cytometer settings and fluorochromes used, they remain generally comparable across different instruments. An orientation panel consisting of 16 antibodies is used for the initial classification of lymphomas, with specific markers allowing for subsequent assessment of antigen expression according to cell type and pathological context. The combined study of cytological and histological features provides an integrated perspective of lymphoid pathology.
