ABSTRACT
We compared the sensitivity and practicability for the direct examination of fungal hypae between the specimens treated with mixed Chlorazol black E solution and simple KOH(potassium hydroxide) solution in 118 cases of superficial myosis. The results were as follows: Higher positivity of fungal hypae in the specimens treated with mixed Chlorazol black E solution(99. 2%) than simple KOH solutiion(87. 3%.). 2, It was time-saving and easy to detect fungal hypae in the specimens treated with mixed Chlorazol black E solution than simple K(3H solution.

We reported a case of cutaneous focal mucinosis in a 19 year-old male, which occured by multiple nodules on the both dorsa of hands, extensor surface of elbows, intergluteal folds and shins, and responded well to intralesional injection of triamcinolon acetonide. Histopathologically, most of the collagen in the dermis is replaced to homogeneous mucinous material which was confirmed as hyaluronic acid.

To characterize the immunopathologic phenotype of the cells in the lesional ti.:sue and to further examine the mechanism of the development of the annular lesions in leprosy, we have studied immune cells (T lymphocyte and its subsets, Langerhans cells, and HLA-DR antigen expressing cells) at different anatomical sites inside, active border, and outside normal skin in the annular lesions of leprosy. We took biopsy specimens from 4 patients of BT type, then processed the specimens by the staining methods eif indirect immunoperoxidase with monoclonal antibodies. In the active border the number of T cell was over 50g of the total cells infiltrated in the dermis. Helper T cells were dominant in number, and about three fourths of the cells were positive for HLA-DR staining. In two patients they had expression of DR antigen on the surfaces of the keratinocytes in the epidermis, in contrast to that of the inside, even the intensities were not. strong. At the inside of the annular lesions T cells were about 40% and the ratio of helper/suppressor T cell was approxiinately 1: 1, However, HLA-DR positive immune cells were not more than 10g among the total infiltrates. Langerha,ns cells were increased in number and in size either in the border or at the inside of the annular lesions. With these results we presume that the T cell mediated imrnune responses against Mycobacterium leprae may play an important role in the formation and extension of the annular lesions in leprosy.

We experienced a case of childhood derrnatomyositis associated with calcinosis universalis in a 3-year-old boy. The skin lesion showed generalized, hard nodules and ulcers, 0, 3-1 cm in cliameter, or the trunk and buttock. The hitopathologic findings revealed patch fat necrosis and calcium deposits in the subcutis.
