title: Malignant lymphomas of follicular centre cell origin in 14 pigs.
abstract: Malignant lymphomas of follicular centre cell (FCC) origin in 14 pigs are described. Seven cases were classified as abdominal type according to the distribution of the neoplastic lesions and the residual cases were of the general type. Most cases were composed of mixed populations of large and medium-sized neoplastic cells and the growing pattern varied from partially follicular to diffuse. The neoplastic cells often showed necrosis, to which macrophages reacted. A part of the neoplastic cells had cytoplasmic immunoglobulin M (CIgM) or cytoplasmic immunoglobulin G (CIgG). The histological features of swine FCC lymphomas are discussed.
