Abstract

Primary vascular tumors of lymph nodes are extremely rare with the exception of AlDS-related Kaposi's sarcoma. The diagnosis of epithelioid hemangio-endothelioma (EH) is difficult to make without ancillary studies, since it is devoid of morphological features indicating its vascular nature and it may be overlooked when it appears as a primary tumor of lymph nodes. Spindle and epithelioid hemangio-endothelioma (SEH) is considered to be a variant of EH, which has been reported to occur exclusively in lymph nodes and the spleen. We report a 70-year-old male with chronic lymphocytic leukemia (CLL) and left cervical lymphadenopathy. An excisional biopsy was performed, and microscopically the lymph node showed effacement of nodal architecture by a tumor composed of spindle cells disposed in intersecting fascicles, and characterized by abundant eosinophilic cytoplasm, elongated nuclei and conspicuous nucleoli. A second population of cells had an epithelioid appearance with intracyto-plasmic vacuoles containing red blood cells. lmmunohistochemically, the tumor cells were positive for CD31 and CD34. The final diagnosis was SEH of the lymph node.
