| lymphoma, large-cell, follicular | Malignant lymphoma in which the majority of neoplastic cells within the follicles are large cleaved or noncleaved cells. The degree to which the follicular centre cells retain their ability to form follicles varies with the state of B-cell transformation. (12 Dec 1998) |

| lymphoma, large-cell, immunoblastic | Malignant lymphoma characterised by the presence of immunoblasts with uniformly round-to-oval nuclei, one or more prominent nucleoli, and abundant cytoplasm. This class may be subdivided into plasmacytoid and clear-cell types based on cytoplasmic characteristics. A third category, pleomorphous, may be analogous to some of the peripheral T-cell lymphomas (lymphoma, T-cell, peripheral) recorded in both the united states and japan. (12 Dec 1998) |
| lymphoma, large-cell, ki-1 | A large-cell, non-hodgkin's, malignant lymphoma with pleomorphic appearance and reactivity with the monoclonal antibody ki-1. The lymphoma is most often found in the skin and lymph nodes and expresses the ki-1 (CD30) antigen (antigens, CD30) on its surface. It is often mistaken for metastatic carcinoma and malignant histiocytosis. (12 Dec 1998) |
