Methotrexate is now used widely for the treatment of acute leukemia, non-Hodgkin's lymphoma, osteogenic sarcoma, choriocarcinoma, breast carcinoma, pulmonary and epidermoid carcinoma, and intrathecal chemotherapy. It is also useful in bone marrow transplantation, severe psoriasis, rheumatoid arthritis, dermatomyositis, Wegener's granulomatosis and sarcoidosis. The recent dramatic intensification of methotrexate therapy can be attributed in part to advances in our understanding of the clinical pharmacology of the folate antagonists, as well as to the combination of positive results and their effective dissemination to medical oncologists. The review summarizes the pharmacologic findings and illustrates how they are currently being applied to the treatment of malignant disease.

Five patients suffering from non-Hodgkin's lymphoma associated with an intense infiltration of epithelioid histiocytes and even sarcoid-type granulomas in the involved tissue are described. A similar tissue reaction, at both involved and uninvolved sites, has been described in patients with Hodgkin's disease. The cause of this reaction may be immunological; its prognostic significance still awaits elucidation. In the case of non-Hodgkin's lymphomas, it may cause difficulty in diagnosis of lymphoma and hence may result in unnecessary delay in the initiation of therapy.

In an attempt to further define the nature, occurrence, and relative incidence of splenic sarcoid-like granulomas, 412 splenectomy specimens were studied. In addition to their occurrence in sarcoidosis, granulomas were found in patients with Hodgkin's disease, chronic uremia, non-Hodgkin's lymphoma, and selective IgA deficiency. The inability to demonstrate a specific responsible organism suggests that the lesion is not of infectious cause. The location of the lesions in the areas of antigen-trapping in the spleen, and their occurrence in both neoplastic and nonneoplastic diseases associated with abnormal or defective immunity suggests that they represent morphologic evidence of a nonspecific defect in antigen processing.

A-31-year-old man with right cervical and supraclavicular lymphadenopathy was admitted in March, 1991. He was diagnosed as having muscular sarcoidosis at the age 8 year, and was treated with corticosteroids. Since age 18, his skin was erythematous and ulcerous, and later his skin became gradually atrophic. Lymph node biopsy revealed diffused large cell non-Hodgkin's lymphoma. Lymphoma cells showed TCR-beta gene rearrangement by Southern blot hybridization. His lymphoma was refractory to CHOP and CHOP-Bleo regimens. Complete remission was achieved with cisplatin and etoposide. However, early relapse occurred, and he died of pulmonary hemorrhage 4 months after the diagnosis of non-Hodgkin's T-cell lymphoma. The so called "sarcoidosis-lymphoma syndrome" is uncommon in Japan. In 9 of 10 cases previously reported, malignant lymphoma occurred during the course of sarcoidosis. Most of the sarcoidosis cases were chronic active type, and required systemic administration of corticosteroids. Hodgkin's disease coexistent with sarcoidosis as reported in other countries, was not found in Japan. These findings suggest that the low incidence of sarcoidosis-lymphoma syndrome in our country is due to the relative rareness of Hodgkin's disease. The sarcoidosis-lymphoma syndrome possibly appears as a consequence of immunological abnormalities observed in sarcoidosis.

The authors analysed 116 hospitalized patients who, in their routine cytologic examination of the sputum, had also a cytomorphologic finding of lymphocytes. The greatest majority of these patients, 63 of them or 54.3% suffered from malignant neoplasm. Out of these 63 patients, 53 of them or 45.7% suffered from primary bronchial carcinoma, whereas 10 patients or 8.6% had non-Hodgkin's lymphoma, metastatic lung cancer of extrathoracic primary localization, Hodgkin's lymphoma, while two patients were supposed to have lung neoplasm. Our study also revealed that 14 patients (out of 116 hospitalized patients) or 12.0% suffered from broncho-pleuropneumonia, 13 or 11.2% from an active pulmonary tuberculosis, 7 or 6.0% from a chronic obstructive bronchitis, 5.1% from sarcoidosis, 3.4% from post tuberculosis pulmonary changes while 2.5% of the patients were found to have a pleural empyema. One case of bronchial asthma, tuberculous pleurisy, bronchiectasis, hamartoma, hemoptysis and a pulmonary infarction were found as well. Due to their own experience the authors conclude that the lymphocytes in the sputum were found to be the most frequent in patients suffering from primary bronchial carcinoma, broncho-pleuropneumonia and pulmonary tuberculosis but that they could also be found in many others pathologic changes of pulmonary parenchyma.

We describe two patients with diffuse non-Hodgkin's lymphoma, hypercalcemia, and increased activity of serum angiotensin-converting enzyme. A mechanism similar to that operative in sarcoidosis is speculated to have caused the hypercalcemia. A lymphokine elaborated by the malignant lymphoma may cause activated macrophages to produce 1,25-dihydroxyvitamin D3.

Focal changes in the spleen were rare findings in a large clinical material (less than 1% of cases). In a prospective study, which included 580 patients, lesions in the spleen were found in 40. Four focal lesions were due to infiltrates from non-Hodgkin's lymphoma. Twenty-one lesions with low echoes consisted of twelve infiltrates from Hodgkin's disease (six patients) or non-Hodgkin's lymphoma (six patients), five were due to fresh splenic infarcts and one each to an abscess, a metastasis from a carcinoma of the stomach, sarcoid and a haemorrhage. In only three of ten highly echogenic foci was a diagnosis possible (one leukaemic infiltrate and two scars following splenic infarcts). The significance of the sonographic demonstration of focal splenic lesions for diagnosis and treatment is discussed. The advantages of a sector scanner for evaluation of the spleen and splenic size are mentioned.

The current literature contains reports of sarcoidosis with polyclonal increases in immunoglobulins. There are also reports of lymphoma in patients with pre-existing sarcoidosis. This is believed to be the first report of a patient in whom a monoclonal IgM kappa paraproteinemia developed after the diagnosis of sarcoidosis. This paraproteinemia was linked with a histologically proved non-Hodgkin's lymphoma. The possible relationships between the two disease entities are discussed.

Five rat monoclonal antibodies (McAbs) to human macrophages are described: YTH 8.18, YTH 25.7, YTH 51.1, YTH 85.12.1, and YHB 65.5. These McAbs are divided into three groups, since YTH 8.18, YTH 51.1, and YHB 65.5 are thought to identify the same antigen. These McAbs react with some bone marrow blast cells, granulocytes, and different percentages of peripheral blood monocytes. When studied on different body tissues, they were found to identify all members of the mononuclear phagocyte system (MPS), except Langerhans cells of skin and epithelium and in the case of one group (YTH 8.18/YTH 51.1/YHB 65.5) osteoclasts. In nine reactive lymph nodes the anti macrophage McAbs identified germinal centre macrophages, sinus macrophages, and interdigitating cells, but not dendritic reticulum cells. They also identified epithelioid macrophages and Langhans-type multi-nucleated giant cells in lymph nodes involved in granulomatous lesions (sarcoidosis and toxoplasmosis). In 24 cases of non-Hodgkin's lymphoma, the antimacrophage McAbs identified reactive macrophages in cases of B- or T-lymphocyte origin, whereas in three selected cases of true histiocytic lymphoma all the McAbs were found to be reactive with the vast majority of neoplastic macrophages as they were with the cells of a neoplastic macrophage line (U937). The possible use of these McAbs in the identification of benign and malignant macrophages in different systems is discussed.

A 70 year old woman had a [99mTc]sulfur colloid liver/spleen scan that showed splenomegaly and multiple intrasplenic defects. The lesions failed to concentrate radiogallium. Thirteen days later, after being on steroid therapy, the spleen had decreased in size and the lesions were only barely apparent. The intrasplenic process, due to non-Hodgkin's lymphoma, was thus markedly sensitive to steroids. It is uncertain if such rapid regression can be employed as a prognostic indicator in non-Hodgkin's lymphoma and suggests the need for further monitoring. The differential diagnosis of the rapid response of intrasplenic lesions to steroids is a limited one, and likely includes sarcoidosis.
