RESUMO
Candida granuloma is a variant of chronic mucocutaneous candidasis associated with chronic infection mainly by Candida albicans in which the skin lesions are rather granulomatous and hyperkeratotic. To date a variety of defects of cell mediated immunity have been shown to be important. We describe a 2-year-old boy with cutaneous candida granuloma and immunologic dysfunction.

Crohns disease is a granulomatous isease of the gastrointetin 1 tract, especially terminal ileum, but may involve the lip, mouth, anus, skin, liver and bone. The skin is a common site of extraintestinal involvement in Crohns disease, with the perianil, perineal, and peristomal areas most frequently affected. Vulvar involvement, however, is an uncommon extraintestinal manifestantion of Crohns disease. We report a case of a 16-year-old girl with Crohns disease of the vulva and perianal region. A histopathologic study of the descending colon and vulvar skin showed noncaseating granulomatous reactions composed of lymphocytes, epithelioidell and giant cells. We were able to make the diagnosis of Crohns disease of the vulvar and the patient was treated with prednisolone and metronidazole.

The epidermal cell-derived thymocyte activating factor (ETAF) produced by keratinocytes and endowed with IL-1 like activities, can potentiate or stimulate a variety of immune reactionsl. In addition to stimulating thymocyte proliferation, it enhanced IL-2 production by mitogen-stimulated lymphocytes. In this study, IL-2 activity stimulated by ETAF was investigated by using peripheral lymphocytes (PBL)and LBRM33 1A5 cell lines. The expression of HLA-DR antigen and the effect of r-IFN-gamma on IL-1 production by keratinocytes were also evaluated : 1. The HLA-DR positive cultured keratinocytes were obser ved in interferon (IFN), interferon-phorbol myristic acid (IFN-PMA) and interferon-lipopolysaccharide (IFN-LPS) groups. There was no HLA-DR expression in the control. PMA. and LPS group. 2. Il-1alpha from supernatants of cultured keratinocytes were produced by all groups including control group. The amounts of IL-1alpha produced by IFN, IFN-PMA and IFN-LPS groups were higher than the other groups. 3. There were no statistical differences between total IL-1alpha from cultured keratinocytes and control or other experimental groups. 4. In experiment for positivie control, the anrounts of IL-2 production by PBL and LBRM33 1A5 cell line were increased proportional to the concentration of added rIL-1. But there was no difference between groups above 1.0 U/ml and 0.5 fmol in LBRM33 1A5 cell line. 5. the production of IL-2 by PBL were increased by phytohemagglutinin (PHA), PHAPMA and PHA-LPS groups. There were no production of IL-2 in control, IFN, LPS, only LPS added group, and IL-1alpha. The IL-2 induced by PHA-PMA group was much higher than the other groups. The production of IL-2 was stimulated by IL-1 of supernatarnts and cell lysates from the cultured keratinocytes, but here was no correlation between IL-2 production and added IL-1. 6. The production of IL-2 by LBRM33 IA5 were increased by PHA, PHA-PMA and PHA-LPS groups. There were no production of IL-2 in the other groups. In summary, the results suggest that supernatants and cell lysates from cultured keratinocytes can stimulate the IL-2 production by human PBL and LBRM33 1A5 cell line. Therefore the ETAF can potentiate or stimulate the immune reactions and enhance IL-2 production by mitogen-stimulated lymphocytes.

A 38-year-old man presented with a 2-year history of recurreit irticaria, abdominal pain and arthralgia of his finger joints. These symptoms were not con rolled in spite of taking medication and had a tendence to be aggravated in the winter. Laboratory findings revealed hvpocomlementemia, hypergammaglobulinemia and a positive rect on with an ice cube test. Skin biopsy specimen taken from the urticarial lesion of the left upper arm showed leukocytoclastic vasculitis with perivascular neutrophilic infiltrition, nuclear dusts, and extravasation of red blood cells. We thus made the diagnosis of hypocomplementemic urtirarial vasculitis syndrome with cold urticaria. The patient was treatcd ith systemic corticosteroids and antihistamines.
