CD30 is a cytoplasmic- and cell surface-associated protein expressed by a significant subset of activated B cells and T cells. CD30 is expressed at variable levels by Reed-Sternberg cells and variants in the majority of cases of classical Hodgkin lymphoma. Among the non-Hodgkin lymphomas, CD30 is strongly and uniformly expressed in anaplastic large cell lymphoma, and at variable levels in a significant subset of other non-Hodgkin lymphomas, particularly those of large cell type. CD30 is also expressed by embryonal carcinomas. Subcellular Localization: Membranous and cytoplasmic
Disease State: Large Cell Undifferentiated Malignant Neoplams
