We report on a 72 years old man showing a strikingly fast spreading malignant melanoma developing on a lupus vulgaris which had existed since childhood. The coincidence of both diseases is obviously extremely rare. A pathogenetic relationship between melanoma and lupus vulgaris, such as claimed for carcinoma in lupo, especially after X-ray irradiation, is not inferable.

Human endothelial cells (EC) cultured from umbilical cord veins were reacted with sera from patients with systemic lupus erythematous (SLE), rheumatoid arthritis (RA) and normal persons. Immunofluorescent staining for IgG, IgM and IgA was then performed. Two types of control cells were also used, human foreskin fibroblasts and KB cells (a human carcinoma cell line). Sera from 9 of the 18 (50%) SLE patients showed cytoplasmic staining of EC for IgG. KB cells and fibroblasts did not stain. None of the RA or normal sera showed positive staining. In the 9 instances in which there was positive staining, 4 had evidence of cutaneous vasculitis. In contrast, none of the 9 patients without EC cytoplasmic staining had clinical evidence of cutaneous vasculitis. This data suggests that some SLE patients have an IgG antibody that reacts with EC cytoplasm which may be related to cutaneous vasculitis.

Two cases of systemic lupus erythematosus in association with primary gastric adenocarcinoma are presented. A pathological analysis of the two cases of gastric cancer does not support the hypothesis that lupus and its associated vasculitis is involved in the pathogenesis of gastric carcinoma. A critical review of the literature reveals numerous case reports suggesting the association of systemic lupus erythematosus with various malignancies; however, there is no definitive study which substantiates the association of gastric or other cancers with lupus. Future studies will be required to assess appropriately the possibility of an association between lupus and cancer.

A modification of the microcytotoxicity assay of Terasaki & McClelland was used to screen for serum inhibitors of myeloid progenitor cells (CFU-C). Sera from 104 patients with neutropenia or bone marrow failure and from 104 controls, including 30 normal subjects and 74 patients with various disorders or multiple transfusions, were studied. Inhibitors of CFU-C were found in 19 of the 104 patients with neutropenia or marrow failure: three with acquited neutropenia and 16 with aplastic anaemia. In 17 of the 19 patients the inhibitor was either complement dependent or chavincingly associated with clinical remission of disease in one patient. In another patient, the inhibitor was an IgG antibody directed against non-HL1 antigens present on CFU-C of all 50 normal target marrows tested; however, it was not clearly autoreactive. Inhibitors were also found in one of nine patients with lupus erythematosus, one with breast carcinoma, one patient with renal transplant rejection, and six of 46 multiply transfused patients without marrow failure. Our findings indicate that most serum inhibitors are associated with multiple transfusion: convincing evidence of pathogenetically important autoreactive antibody was present in only one of 19 patients with inhibitors.

Department of molecular basis of semiotics was organized in 1986. The main task of the department was to work out new approaches in estimation of the state of immune and blood system at the tissue, cell and molecular levels, using biochemical, biophysical and molecular biology techniques. There are several main directions of scientific investigations at the department. Most informational methods were collected in "immunological portrait" for differential diagnostic and complex investigation of the immune system of autoimmune patients. This group of techniques was used to study changes in the immune system of Kievites after the Chernobyl disaster. A decrease of complement and thymic serum activity was detected. Antibodies against nuclear components appeared in 20% of donors. And a higher of circulating immune complex of low molecular weight was observed. Low level of thymic serum activity in blood of autoimmune patients with rheumatoid arthritis, lupus erythematosus, diabetes, herpes and other depends on the appearance of zinc-independent timuline inhibitor less then 2000 D. Another kind of thymic hormone inhibitors was detected in thymectomized adult mice. Its effect disappears when zinc added in blood rather due to competition for lymphocyte surface receptors timuline and its inactive analogue than other mechanism. Therapeutic effect of UV irradiation of patients' blood was shown to be closely connected with the changes in thymic serum activity in respect to stabilization of thymic hormone/inhibitor ratio. The immunochemical techniques were used to detect and investigate tumor-associated chromatin antigens in human and animal tumor cells. Antigens not found in normal tissues were detected when using rabbit antibodies against chromatin of rat hepatocarcinoma and human colon and carcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)

214 skin lesions have been analyzed in the paper and 158 cases of Carcinoma basocellulare, 22 cases of Carcinoma planocellulare and 11 cases of melanoma were registered. Concerning localization it has been established that skin of the face is mostly endangered both for malignant and benign lesions. In 10 cases Keratosis senilis, a benign kind of lesion, was diagnosed, Dermatitis post irradiationem was diagnosed in 8 cases and Lupus erythematodus in 5 cases. By histologic analysis the following can be stated: if the degree of degradation and damage of collagen fibers is high, the intensity of lymphoplasm infiltrate density and intensity of mastocyte cells density is reduced. If the degree of decomposition of collagen fibers is lower, the lymphoplasmocyte infiltrates are denser as in the stroma of the lesion as well in edges and in the surrounding dermis. Changes were primarily found in malignant skin lesions, but they are identical in cases of keratosis senilis as a premalignant lesion. However, concerning nonmalignant lesions, depending on exterior factors, long time influence of noxa, collagen fibers and their degree of degradation have an important role in the cell interaction, and more attention should be paid to exploring decomposition of collagen fibers as components of the local immunobiologic reaction of the organism to lesion formation.

The association of systemic lupus erythematosus (SLE) and malignancy has been reported previously and suggests an increased risk of cancer in this disease. Lymphomas are the most frequent neoplasias reported in these patients and carcinoma of the cervix and breast are also seen. Several factors probably play a role in the aetiology of malignancies associated with SLE including intrinsic disturbances of immunity and concomitant immunosuppressive therapy. We report five solid tumors (one breast carcinoma, one squamous cell carcinoma of the anus, one adenocarcinoma of the rectum, one carcinoma of the cervix and one carcinoma of the gallbladder) among 96 patients with SLE. The most striking finding in this study was the absence of haematological malignancies. The incidence of malignancy in the series, the age of diagnosis of SLE and neoplasia and the time delay between SLE and malignancy diagnosis was similar to other series. We did not find any clinical or immunological feature that predicted the development of neoplasia. In conclusion, patients with SLE may have the same malignancies as the general population after adjustment for age and sex. There are no predictive indicators for malignancy and immunosuppressive therapy may be a contributing factor.

We describe a patient with systemic lupus erythematosus (SLE) who presented with severe refractory pannicular lesions diffusely involving the buttocks and lower extremities. Due to the severity of these lesions, a biopsy was performed, which implicated panniculitis associated with pancreatic disease, rather than lupus panniculitis. Serum amylase was normal, but the serum lipase was markedly elevated. An abdominal computerized tomographic scan demonstrated a pancreatic mass, which upon laparotomy was found to be an acinar cell carcinoma. After resection of the mass, her symptoms improved, where they had not responded to prior immunosuppressive therapy. She has subsequently remained well without recurrence of the disease. This case illustrates that an uncharacteristic presentation of panniculitis in a patient with lupus does not necessarily imply lupus panniculitis, and a biopsy is imperative to distinguish other sometimes life threatening etiologies.

Two cases of diabetic mastopathy are reported. The patients presented with a rapidly increasing mammary mass. The pathologic findings of diabetic mastopathy usually consist of a lymphocytic lobulitis, a dense stromal fibrosis and prominent epithelioid fibroblasts. In our two cases, the latter findings were initially misinterpreted as malignant cells of an invasive lobular carcinoma. These lesions were first described in longstanding insulin dependent diabetics but recent reports showed that they could also occur in patients with other auto-immune disorders (systemic lupus erythematous, hypothyroidism). Diabetic mastopathy may reoccur locally and the treatment remains to be determined.
