The development of malignant lymphoma in myoepithelial sialadenitis with and without Sjögren's syndrome was investigated. At first, prelymphomatous proliferation areas showing a polytypic immunoglobulin (Ig) pattern were seen. These transformed into malignant lymphoma with a monotypic Ig pattern, at first in small, circumscribed proliferation areas ("early lymphoma") and later in large, conflue...

Malignant lymphoma is classified roughly into Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL) according to the biological characteristics. Malignant lymphoma in Japan has such characteristics as low incidence of HD, which is usually favorable in prognosis, and high incidence of NHLs, which have further distinctive features of less incidence of favorable follicular B cell lymphoma and of...

BACKGROUND Lymphoid cells may express somatostatin receptors (SS-Rs) on their cell surface. Therefore radiolabeled somatostatin analogues may be used to visualize SS-R-positive lymphoid neoplasms in vivo. Exact staging is the basis for treatment decisions in cutaneous malignant lymphoma. We considered the possibility that SS-R scintigraphy might offer a clinically useful method of diagnostic im...
