The clinical and pathological findings in a patient with monocytic aleukemic leukemia presenting initially as multiple monoblastic tumors of the skin is described. The patient was a 35-year-old Japanese woman, who had first noticed multiple, asymptomatic, reddish-brown papules on her trunk. Asymptomatic enlargements of several lymph nodes were present in the bilateral cervical and axillary areas. There was no hepatosplenomegaly, sternal tenderness, bruising, or bleeding. The skin and lymph node biopsies were originally interpreted as malignant lymphoma. The diagnosis of acute monocytic leukemia was established when bone marrow involvement was detected. Immunohistochemical observation of the skin eruptions revealed the following: Positive staining with lysozyme was noted in almost half of the infiltrating atypical cells. Most of the infiltrating cells reacted positively with antisera to Leu-M5 and some of them reacted to Leu-M1. The helper T cell antibody, Leu-3a+3b, showed weak positive staining of most infiltrating cells. However, there were no reactions with antisera to Leu-6, Leu-7, Leu-14, CALLA, OKT 6, OKT 8, OKT 16, OKB 19, OKM 14, beta F1, or delta TCS1. OKM 5-positive keratinocytes were observed in some parts of the upper epidermis, although no OKM 5 expression could be detected on any tumor cells. Cytochemistry, immunohistochemistry, and electron microscopy can aid in the diagnosis of monocytic leukemia. This case illustrates the importance of using an expanded panel of monoclonal antisera in certain hematopoietic tumors.

A firm, dark reddish, smooth surfaced nodule on the forearm of a 16-year-old boy was diagnosed as a Spitz nevus with the aid of a strong positive reactivity to S-100 protein. Histological examination revealed an intradermal epithelioid cell tumor with prominent multinucleated giant cells, suggesting the diagnosis of reticulohistiocytic granuloma. However, immunoperoxidase staining of the tumor cells showed strong positive reactivity to S-100 protein and vimentin; it was negative for lysozyme and alpha-1 antitrypsin. Although a few melanosomes in the tumor cells seen in electron microscopic examination provided crucial proof for the diagnosis of Spitz nevus, the positive reactivity to S-100 protein in ordinary formalin-fixed, paraffin-embedded tissues proved to be very useful in the differentiation of Spitz nevus from tumors of histiocytic origin, especially those of the mononuclear phagocytic system.

The authors analyze the immunity-correcting effect of antibiotic and enzyme therapy in 32 patients with gonorrheal orchidoepididymitis and 31 with gonorrhea relapses and compare it to the results of routine therapy in 60 patients with chronic and complicated gonorrhea. They come to a conclusion that combined administration of proteolytic enzymes and antibiotics more effectively corrects a number of disordered immunity nonspecific defense parameters (blood serum levels of circulating immune complexes and lysozyme).

The localization of lysozyme in human apocrine glands was studied by adopting the avidin-biotin-peroxidase complex method. The results showed that the glands were enriched with lysozyme. The apical portion of secretory cells was most heavily stained. Eccrine glands did not stain for lysozyme. Although apocrine glands have been regarded as having no apparent function in man, it is suggested in the present report that they may have an excretory bactericidal role.

Lysozyme was administered to 57 patients with lupus erythematosus (LE) for 10 days according to 4 schemes: Group 1 (n = 10)--30 mg of lysozyme 3 times a day sublingually; Group 2 (n = 10)--100 mg daily i.m.; Group 3 (n = 10)--100 mg twice a day i.m.; Group 4 (n = 27)--100 mg 3 times a day i.m. After a course of lysozyme therapy patients with discoid and disseminated LE were prescribed delagil, those with systemic LE were administered corticosteroid hormones in moderate doses or presocyl. The treatment was well tolerated, only 2 (3.5%) patients developed toxicoderma. The results evidence that lysozyme efficacy is not inferior to that of levamisole but this agent is better tolerated. Clinical and paraclinical efficacy was higher in Groups 1 and 4; cellular, humoral, and local immunity parameters, as well as the characteristics reflecting the inflammatory processes evidence positive changes developing as a result of lysozyme therapy, these changes persisting in the majority of cases during further combined treatment. Therapy with low doses of lysozyme is indicated for patients with the immune status disorders mainly. If changes in the nonspecific resistance predominate, the scheme used in Group 4 is advisable.

The clinical association of lymphomatoid papulosis and Hodgkin's disease and the striking morphologic similarity of atypical cells in lymphomatoid papulosis to Reed-Sternberg cells in Hodgkin's disease suggest that lymphomatoid papulosis and Hodgkin's disease are related. To test this possibility we studied the antigenic profile of Reed-Sternberg cells in the lymph nodes and of atypical cells in cutaneous lesions of lymphomatoid papulosis in two patients with Hodgkin's disease and lymphomatoid papulosis. In paraffin sections both cell types expressed CD30, CD45 T cell-restricted antigens, and occasionally CD15 antigens. They were negative for CD45 B cell-restricted antigens and for lysozyme. In cutaneous lymphomatoid papulosis lesions a similar immunologic profile of the atypical cells was found; that is, they were positive for CD30, CD2, CD3, and CD25 but negative for B cell and macrophage antigens. The similarity of the immunophenotype of Reed-Sternberg cells in lymph nodes affected by Hodgkin's disease and the immunophenotype of atypical cells of lymphomatoid papulosis lesions in the same patients suggests that the malignant cells in both conditions are derived from activated T cells and that they are closely related if not identical.

Twenty undifferentiated skin tumors were examined by immunostaining in an attempt to achieve more precise identification. Light microscopy yielded only a differential diagnosis, whereas immunostaining of formalin-fixed, paraffin-embedded tissue sections with a panel of antibodies to intermediate filaments and other cell components led to a definitive diagnosis. Four cytokeratin-positive epithelial tumors were subtyped into squamous cell carcinomas and adenocarcinomas with the use of antibodies to different cytokeratin polypeptides. Fifteen vimentin-positive tumors were subdivided into malignant melanomas with the use of antibody to S-100 protein, lymphomas with the use of antibody to immunoglobulin, and mesenchymal tumors (angiosarcomas, atypical fibroxanthomas, dermatofibrosarcoma protuberans, and meningiomas) with the use of antibody to S-100 protein, factor VIII, and lysozyme. One desmin-positive tumor was diagnosed as a leiomyosarcoma of the skin. A scheme is presented for using immunohistochemistry to facilitate the diagnosis of undifferentiated tumors involving the skin.

Examinations of 46 patients with gonorrheal orchiepididymitis have revealed reduced IgA, IgG and IgM levels, a rise of circulating immune complexes level, and depressed lysozyme activity. Addition of proteolytic enzymes to combined therapy has improved the treatment efficacy and normalized the humoral immunity and nonspecific defense parameters.

The determinations of the activity of lysozyme in the serum, lysosomes and lysosomal supernatant of neutrophil granulocytes were done in 33 patients with generalized psoriasis and in 19 healthy controls. A decrease of lysozyme activity was demonstrated in the serum, lysosomes and lysosomal supernatant in the patients. During treatment by the PUVA method this activity rose gradually above the values in the control group. Systematic determination of lysozyme activity may help in monitoring of treatment progress.

The authors analyze the efficacy of treatment of 162 patients suffering from psoriatic arthritis in Evpatoria health resort. The treatment modalities included brine baths, mud applications, climatotherapy, etc. Clinical cure or considerable improvement has been achieved in 21.8% of patients, improvement in 74.3%, no therapeutic effect in 3.9%. Along with alleviation of the clinical manifestations of psoriatic arthritis, a number of immunological and biochemical parameters (albumin, lysozyme, IgM levels) have shown a tendency to normalization. The combined health resort therapy is an effective means of the after-care of psoriatic arthritis.
