Angioimmunoblastic T-cell lymphoma (AITL) is a rare subtype of malignant lymphoma (ML), accounting for only 1 to 2% of all non-Hodgkin's lymphoma (NHL). Although ML of the parotid gland is rare, the majority are B-cell types. The AITL occurring synchronously in the parotid gland and lateral neck has not been reported earlier. It is classified as a high-grade malignancy with aggressive clinical features, and the prognosis is worse than any other type of NHL. We recently encountered a 72-year-old man with multiple mass on the ipsilateral parotid tail and lateral neck, and he was finally diagnosed as AITL. We report the unique and rare disease entity with a brief literature review.

Recently, we experienced a case of Angioimmunoblastic T-cell lymphom (AITL) in a 60-year-old man presented with lymphadenopathy, which is first cytological report in Korea. The cytological features showed a heterogeneous population of small to medium-sized lymphocytes, immunoblasts, and plasma cells. Characteristically, there were also a distinct population of follicular dendritic cells admixed with lymphoid cells, forming the so-called dendritic cell-lymphocyte complexes. Histological features showed the classic morphologic features of AITL. Recognition of the characteristic cytological features can suggest the possibility of AITL.
