Lymph node infarction in association with malignant lymphoma

Abstract

Spontaneous infarction of lymph node seldom occurs because of dual vascular connection and low oxygen consumption of activated lymphocytes. Infarction of lymph node with malignant lymphoma is also rare, probably cue to the same reason as that of normal nodes , We report three ,ases of lymph node infarctiolj Lymphomain malignant lymphoma: two cases of lymphomatous lymph node and one case of nonlymphomatous lymph node. Their ages were 24,46 and 50 years Locations were two cervical and one inguinal areas. All cases were confirmed to be malignant lymphoma at the margin of infarcted node, other lymph nodes or previous biopsy. Histologic types of the cases were diffuse histiocytic (Rappaport) and large cell noncleaved type (Lukes·Collins). Infarcted area showed coagulation necrosis and surrounding granulation tissue. Special stains showed neither microorganism nor evidences of infection.
