Surface Marker Studies of 3 Cases with Primary Lymphoma of the Bone

Abstract

We report surface marker studies for three cases with primary lymphoma of the bone. These cases were staged at IV, III, and I by the Murphy's classification, respectively. The following were histopathological features of these 3 cases : one case was classified as lymphoblastic type, and the other 2 cases were classified as diffuse medium cell type according to the LSG classification. All cases including lymphoblastic type were originated from non T cell, and two of these were shown to be positive for CD 10 (CALLA). Recently, primary lymphoblastic lymphoma of the bone has been increasingly shown to be positive for CD 10 (CALLA). Studies of surface markers are essential for the accurate diagnosis of cellular origin with primary lymphoma of the bone.
