BACKGROUND: Primary targit injured from the immunologic mechanism of alopecia areata is not definitely confirmed although alopecia areata is regarded as a disease occuring from certain im munologic process. Recently, par ticular interest has been focused on the follicular keratinocytes which show morphologic and anigenic alterations in active lesions. Another important point is the subclinical state hypothesi. It is based upon the observation that the patterns of T lymphocytes infiltration and ultrastructural changes of dermal papilla cells are nearly identical in active lesions and in non-lesional areas of alopecia areata. OBJECTIVE: The purpose of this study is to determine and to compare the aberrant expression of HLA-DR, CD1 and ICAM-1 on the follicular keratinocytes from the active alopecia areata lesion, stationary lesion and non-lesional scalp. METHODS: We performed a n immunohistochemical study, using the streptavidin system to compare the patterns of HLA-DR, CD1 and ICAM-1 immunoreactivity in the follicular keratinocytes in five active alopecia lesions two stationary lesions and non-lesional scalp specimens among four active and two stationary patients, and two normal control scalp specimens. RESULTS: In the active aloecia lesions, the HLA-DR and ICAM-1 immunoreactivity was observed in some patients while CD1 immunoreactivity was observed in all the patients. In the sta tionary alopecia lesions, none of the HLA-DR or CD1 or ICAM-1 immunoreactivity was observed as was the case in the norrial control scalp specimens. In the non-lesional normal scalp specimens, the HLA-DR, CD1 and ICAM-1 immunoreactivity showed nearly the same patterns as those in the acute alopecia leions. CONCLUSION: The aberrant antigenic alterations, especially CD1 expression of follicular keratinocytes are likely to be asociated with the active progress of alopecia areata lesions. These antigenic alterations were also observed in non-lesional scalp as well as alopecia areata lesions in the very similar patterns.

BACKGROUND: Interferon alpha-2a has already been shown to be effective in clinical use of virus-originated diseases such as hairy cell leukemia, condyloma acuminatum, and AIDS-related Kaposi's sarcoma. The use of recombinant alpha-interferon may allow common warts to be treated relatively atraumatically and with less incidence of recurrence. OBJECTIVE: We tried to determine the safety and effectiveness of intralesional injections of recombinant alpha-2a interferon in the treatment of patients with common warts. METHODS: A single wart on each patient was weekly injected with 0.75 to 1.5×10(5) IU/25mm2 of interferon for 8 weeks, and the response to treatment was followed up-to 6 months. RESULTS: Clearing of the treated wart at the end of treatment occurred in 5(71%) out of 7 patients and the rest showed no improvement. With evaluation for relapses up-to 6 months after treatment, warts relapsed in 2(40%) out of 5 patients. Therefore, 3(43%) out of 7 patients were completely free of warts 6 months after treatment. CONCLUSION: Intralesional recombinant interferon alpha-2a has a limited therapeutic effect, but may be considered as a therapeutic modality of recalcitrant verruca or when it can be anticipated that destructive techniques or blistering agents will not be tolerated.

Chondroblastoma is a rare primary bone tumor which originates from cartilage, and represents approximate 1% af all bone tumor. The chondroblastoma arises most frequently from the epiphysis of the long bones with the humerus being the commonest site. It afflicts usually the young under 25 years with greater incidence in male. As there is no cartilage cell on craniofacial bone which is mainly fromed by intramembranous ossification, the chondroblastoma on the craniofacial bone is extremely rare. But the chondroblastoma recurred frequently in craniofacial bone when the mass is excised incompletely or curretted and, as the tumor has the outstanding ability of local invasiveness, it destructs the adjacent bone. In addition, it is difficult to diagnose differentially from sarcoma or giant cell tumor histopathologically. Due to the entities described above, it is necessary to remove the entire tumor mass as complete as possible, to treat with radiation pre or postoperatively for preventing from recurrence, and to observe for a long time. The chondroblastoma on temporal bone is rare and is difficult to diagnose and treat successfully. So we'd like to present a case of chondroblastoma which was originated from temporal side of TMJ with literatural review.

We reviewed 50 skin biopsies obtained from 40 patients with cutaneous leiomyoma during a 10 year period from January 1980 to December 1989. The result.s were summarized as follows: 1) Sex distribution showed a female preponderance with male.female ratio of 1: 1.9. 2) The age distribution was relatively even from childhood to old age. The mean age was 47,8 years, 3) The most common site of lesion was lower leg(34%) followed by hand(24%), foot(12% ), anterior chest(8% ), face(6% ), neck(4%), upper arm(4% ), labia major(2 %) and nipple(2%). 4) The lesions were relatively well circumscribed subcutaneous nodule, papule, plaque and nodule which measured between 0.3cm to 5cm in size and their colors were erythematous to light brown. 5) The most common clinical and histopathologic type was angioleiomyoma(75%) followed by solitary piloleiomyoma(12.5%), multiple piloleiomyoma(7,5%) and solitary genital leiomyoma(5% ). Angioleiomyomas were clincally associated with cavernous hemangioma, myoma of uterus and systemic lupus erythematosus. 7) The clinical diagnoses were mass(30% ), epidermal cyst(20%), dermatofibroma (12.5% ), leiomyoma(12,5%), neurilemmoma(5%), lipoma(5%), calcifying epithelioma(2.5%), metastatic carcinoma(2.5%), morphea(2.5% ), fibrocystic disease(2.5%), glomus tumor(2.5 % ) and Dupuytrens contracuture(2..5%).

It is well-known that the infection of bone and joints could produce the shortening by destroying the articuiar cartilage and growth plate, or the lengthening hy increased hlood circulation to the epiphyseal and metaphyseal regions of long bone. Since 1985, we have treated total l7 cases of children s pyogenic or tuberculous children s knee with early arthrotomy and continuous irrigation etc. and followed their long hone growth for average 53 months after surgical intervention. Five patients (group I ) were early treated within 2 weeks and twelve patients(group 3 ) were delayed to treat their knees for more than 2 weeks of symptom development. Total 11 patients out of 17 cases(64.7%) (2 cases of group 1 pyogenic arthritis, and 1 case of group l and 8 cases of group II tuberculous arthritis) revealed growth acceleration. Femoral lengthening was much more greater than that of tibial growth, and the size of patella, distal femoral and proximal tibial epiphysis which were measured by computerized digitizer were also significantly larger than that of opposite knee. The total limb length was increased hy average 7mm in 6 months, l4mm in 1 year and 3mm in 2 years after operation. These results suggest the pyogenic and tuberculous arthritis in children s knee should he treated as early as possible after symptoms developed, and followed them to trace their limh inequality for at least 2 years after surgery. That means the early arthrotomy for tuberculous knee or even in pyogenic arthritis can preserve normal articular cartilage and can also prevent the early epiphyseal closure hy infection. and can get the limh lengthening by increased blood circulation around the knee joint.

In a previous communication, we described a relatively simpli. method for assaying quantities of sweat using the skin surface hydrometer. In order to evaluate the pharmacologic response of weat glands in psoriasis, vitiligo and loalized scleroderma, we measured the basal skin conductance and the quantity of sweat induced by intradermal injections of pilocarpine nitrate in the lesional and per ilesional skin. The results were as follows : 1. In psoriatic plaques, based skin surface hydration and the sweat response to pilocarpine was markedly reduced (p<0.05), but there were no significant differences in normal perilesional skin. 2. In generalized vitiligo, basal skin surface hydration and the sweat gland response was normal. In the case of the segmental type, there was a slightly decreased sweat response in the lesion but, not significant statistically. 3. In the morphea plaque, basal skin surface hydration and the sw.at response to pilocarpine was markedly reduced but was normal in perilesional skin. This study presents evidence of the functional changes in the development of sweat secretion and surface hydration in the lesions of psoriasis, morphec and segmental type of vitiligo. The demonstration of ahnormalities in the pharmacolopic response to pilocarpine induction led us to suggest the possibility that some degree of sweat gland involvement is induced by the pathogenetic mechanisms of these diseases.

Lymphangioleiomyomatosis(LAM) is a rare disease of women of child-bearing age in which there is progressive hyperplasia of atypical smooth mucle along lymphatics in the lung, and/or axial lymphatics in the thorax and abdomen, resulting in honeycombing of lung. Interestingly there has been a speculation that it represents a forme furste or incomplete expression of tuberous sclerosis complex. This is based on the observation that patients with tuberous sclerosis can manifest pulmonary lesions indistinguishable from LAM. We report a case of LAM occuring in a 39-year-old female, who complained of recurrent pneumothorax, chest pain and shortness of breath. Three years ago, the patient had right nephrectomy under the diagnosis of ruptured angiomyolipoma. A X-ray film of the chest showed honeycombing with a diffusely reticulonodular pattern and cyst-like spaces. She had a characteristic facial appearance of adenoma sebaceum, which her father and uncle had. Microscopically, the lung showed a marked smooth muscle proliferation around the slit-like lymphatic spaces and also some respiratory bronchioles.

We present a case of venous hemangioma which is seen beneath a clavus (corn) developed in the interdigital area of the foot. Clinically, a violaceous papule was located on the third and fourth interdigital spaces under an overlying corn. Histopathologic examination showed a non-encapsulated dermal mass composed of thick-walled and thin walled vessels lined by a single layer of endothelial cells. Some thick-walled vessels had protruding endothelial cells into the lumen and through Verhoeff-van Gieson and Masson-trichrome stain of the tissue section, we found that the vascular mass was composed of vein.
