title: Primary lymph node presentation of angiocentric lymphoma associated with features of a hemophagocytic syndrome.
abstract: The spectrum of post-thymic T-cell neoplasia includes the angiocentric immunoproliferative lesions, a group of disorders histologically exhibiting vascular infiltration and destruction; included among these disorders is angiocentric lymphoma. In contrast to the typical extranodal presentation seen in the angiocentric immunoproliferative lesions, this report describes a case of angiocentric lymphoma presenting as primary lymph node disease with clinicopathologic findings mimicking a hemophagocytic syndrome. Rearrangement of the T-cell receptor beta chain documents this case to be a clonal T-cell neoplasm. The association of this distinct histologic type of T-cell malignancy with hemophagocytic syndromes is reviewed.
