[Non-malignant lymphoid changes in the lung].

The authors diagnosed 5 cases of lymphoid interstitial lymphomas (LIP) and 2 pseudolymphomas among their patient material. 2 of the 5 LIP patients were men, whereas 3 were women. One of the patients was a 9-year old girl at the time of diagnosis.

[Simultaneous occurrence of lupus erythematosus and desquamative interstitial alveolitis].

Several subtypes can be distinguished within the disease lupus erythematosus according to the clinical appearance, serological and histological findings. With their case reports the authors wish to present that there is no definitive dividing line among them in practice, but transitional appearances and forms also exist.

[Hematologic changes in sarcoidosis].

On the basis of the literature authors analyse the importance of the involvement of spleen in sarcoidosis and the haematological changes that follow from this. In a group of patients with sarcoidosis of their own department (more than 1200 patients) they observed 2 women with thrombocytopenic purpura, one woman with thrombo- and leukocytopenia, and one woman with agranulocytosis. They shortly reviewed the previous history of their patients, the disease process, and the results of the treatment.

[Primary malignant fibrous histiocytoma of the lung].

The authors interpret a case-report on malignant fibrotic lung histiocytoma diagnosed in a 69 year old female. The patient was admitted for examination because of suspicion of tumor. None of the usual pulmonology tests (sputum cytology, fiberoscopy, bronchus-brush-cytology) could reveal the origin of the change.

Transfer factor therapy of thoracic sarcoidosis.

The authors repeatedly treated 59 patients with thoracic sarcoidosis with transfer factor (TF) since 1976. They utilized this therapy with TF from human tonsil lymphocytes (TFh) on account of the ineffectiveness of the corticosteroid treatment, because of the side effects of the corticosteroids, and as primary TF therapy, and to test an animal TF preparation from pig tonsil lymphocytes (TFp). In their observations only fraction II of the dialysable leukocyte extract was sufficient.
