However, CD30 expression has rarely been described in non-lymphoid tissues,[1,8] and few studies have examined its expression in non-lymphoid neoplasms, namely epithelial tumors,[9–13] sometimes with conflicting results.[1,9,11] Specifically, very little data exists about CD30 expression in breast carcinoma or about its association with tumor characteristics. Here, TNFRSF8 is linked to neoplasm.
