The diagnosis of Hodgkin's disease is based on histopathologic examination and the demonstration of Reed-Sternberg cells. These cells express antigens (Ki-1/CD30 CD15) which are of diagnostic value. Two types of Hodgkin's disease are now identified: 1. the "classical Hodgkin's disease" which includes nodular sclerosis, mixed cellularity and some tumors rich in malignant cells formerly designated Hodgkin's disease with lymphocyte depletion; 2. the "lymphocyte predominance Hodgkin's disease" in particular the nodular form (paragranuloma). These lesions are now considered an indolent form of B-cell lymphoma with possible transformation into large B-cell lymphoma. Epstein-Barr virus is involved in the "Classical Hodgkin's disease" but not in the "Lymphocyte predominance Hodgkin's disease". However, the role of Epstein-Barr virus in the occurrence of the disease and the prognostic implications of its detection remain ro be elucidated.

Non-Hodgkin's lymphomas (NHL) were often erroneously diagnosed as other malignancies and treated accordingly. In this study cisplatin combined with vincristine, cyclophosphamide, and Adriamycin was used incidentally as a front-line treatment in seven children with NHL, because the initial histologic diagnosis was that of a sarcoma. After reevaluation three patients had Ki-1 anaplastic large cell lymphoma of T-cell origin, two abdominal B-cell diffuse high-grade NHL, one mediastinal diffuse large B-cell lymphoma, and one B-cell lymphoma in the stomach. They received at least two courses of cisplatin combined regimen and continued with other protocols for NHL. All patients showed an extremely good response from the first course of therapy and the masses vanished completely. They were followed up for a mean time of 29.5 months and are all in complete remission. The data indicate that cisplatin is active against NHL and might be a promising alternative front-line therapy.

Mucosa-associated lymphoid tissue (MALT) lymphoma is listed in the new World Health Organization classification as extranodal marginal zone B-cell lymphoma of MALT. Most cases occur predominantly in adults and are rare in children or adolescents. We report, with a review of earlier literature, a MALT lymphoma of the lower lip in a 7-year-old immunocompetent child. The patient had a sessile, indurated, and firm mass on the lower lip without regional lymphadenopathy. Microscopically, dense lymphoid cell infiltrates composed of small- to medium-sized centrocyte-like cells and plasmacytoid cells infiltrating around scattered reactive germinal centers were observed, with formation of typical lymphoepithelial lesions. Immunohistochemical staining demonstrated positivity of atypical lymphoid cells for CD20, CD43, CD79a, and Bcl-2 and negativity for CD3, CD5, CD10, CD23, Ki-1, Bcl-10, and ALK. Cytoplasmic kappa light chain restriction was demonstrated. We conclude that this case represents the youngest patient with a MALT lymphoma of the lip.

The aim of this study was to report a single center experience of primary pancreatic lymphoma (PPL) in Korea. We analyzed the clinicopathological data from four PPL patients (three male, median age 36 yr) diagnosed from 1997 to 2007 at Seoul National University Hospital. The diagnoses were: diffuse large B cell lymphoma (n=2), Ki-1 (+) anaplastic large cell lymphoma (n=1), and Burkitt lymphoma (n=1). Presenting symptoms and signs were: abdominal pain (n=4), pancreatitis (n=2), weight loss (n=2) and abdominal mass (n=1). No patient underwent surgery. The Ann Arbor stages of the patients were: IEA (n=1), IIEA (n=1), and IVEB (n=2). Two patients underwent treatment. The stage IEA patient underwent chemotherapy and radiation therapy that resulted in a complete remission. The stage IVEB patient who underwent chemotherapy relapsed. This patient underwent subsequent peripheral blood stem cell transplantation and is alive at 30 months. Two patients (stages IVEB and IIEA) without treatment died at 0.8 and 7.0 months, respectively. For PPL patients, chemotherapy-based treatment, and addition of radiation therapy, if possible, may offer good prognosis.
