The quantification and significance of mast cells in lesions of Behçet's disease.
Mast cells in the upper dermis and mucosal subepithelial layer were counted in thirty consecutive light microscopy oil-immersion fields of the following: thirty-four skin and oral specimens from lesions in patients with active Behçet's disease, eight specimens of apparently uninvolved skin of the same patients, and 102 lesions of a variety of other skin diseases. The results revealed a significant increase in the number of mast cells in Behçet's lesions. Furthermore, the histamine content of five reactive lesions showed a two-fold increase compared with that in apparently uninvolved skin of patients with active Behçet's disease. It is suggested that mechanisms similar to cutaneous basophil hypersensitivity may be involved in the production of Behçet's lesions.

HLA-DRw4 in pemphigus vulgaris patients in Israel.
Pemphigus vulgaris (PV) is relatively common in Jews. Three HLA antigens were significantly more frequent in 39 Israeli Jewish PV patients than in controls A26 - 59% vs 20%; Bw38 - 61% vs 20%; and DRw4 - 90% vs 38%. The joint occurrence of A26-Bw38-DRw4 was observed in 46% of PV patients and in 10% of controls. Similar results were recently reported for Jews in the Los Angeles area. Yet, when our patient sample was grouped into Ashkenazi and non-Ashkenazi Jews, it was evident that each of the three antigens had a higher frequency both in Ashkenazi patients and controls as compared to non-Ashkenzai. The relative risk for DRw-4 in Ashkenzim was 33.8 as compared to 14.4 in the total sample of Israeli PV patients. The phenotype A26-Bw38-DRw4 was present in 57% of Ashkenazi patients and in 13% of controls. Ashkenazi Jews have the highest prevalence of PV, and HLA associations were strongest with Ashkenazi PV patients. These associations were with three antigens, all of high frequency in that group.
Generalized familial benign chronic pemphigus.
This is a report of generalized familial benign chronic pemphigus in a Negro male. The rich staphylococcal and streptococcal flora detected on the skin of this patient may have been a factor in the generalization of the process.
Cutaneous pigmentation: a probable sign of spontaneous bacterial peritonitis.
A cirrhotic patient with ascites was apparently well managed with diuretics and salt and water restriction for 9 months. A spontaneous bacterial peritonitis (SBP) developed and the patient finally died following septic shock. There were enough findings indicating that SBP in this case had been existing silently for some time. During this period the only apparent manifestation of this complication was a cutaneous pigmentation on the abdomen. It is suggested that pigmentation may be incuded among other presentations of this frequently silent process.

Chronic pyoderma in splenectomized patient.
This is a report of a case with a chronic peculiar intractable pyoderma. The process started a year after splenectomy because of trauma. In the absence of an apparent other reason, we assume that a relationship exists between the operation and the skin disease.
Leucocyte migration inhibition in Behçet's disease.
The leucocyte migration inhibition (LIF) was investigated in 16 patients with Behçet's disease, 5 while in the active stage of the process, 3 both during relapse and remission, and 8 during remission of symptoms. In all patients skin tests with various antigens and with a needle prick and physiological saline were simultaneously performed. The results indicate a strong correlation between the activity of the disease, skin reactivity and the reactivity of LIF.
Cutaneous sclerosis in eosinophilic fasciitis.
Eosinophilic fasciitis is an additional clinical entity to many others manifested by sclerodermic changes in the skin. A case with this process is reported. It presents vast cutaneous sclerodermic changes associated with eosinophilia, signs of muscular exertion, and a massive inflammatory infiltrate involving the lower part of the dermis, subcutaneous tissue and the muscle fascia. Prednisone therapy was followed by rapid and marked improvement.
Vitiligo associated with BCG-methanol extraction residue in malignant melanoma. Report of a case.
A pronounced vitiliginous reaction developed at the sites of MER/BCG injections given as an adjuvant immunotherapy to a patient with malignant melanoma. To our knowledge, this is the third report on patients exhibiting vitiligo apparently induced by immunotherapy and the first in association with MER. This association may be a sign for an antimelanocytic effect and may offer a further confirmation for the autoimmune nature of vitiligo.
