Sarcoidosis is a rare d:sease in Korea and its association with erythema nodosurn is even rarer. Recently we saw a patient of bihilar adenopathy, who had arthralgia and erythematous nodules of both lower legs. A skin biopsy obtained from the erythematous nodule of the lower leg showed septal panniculitis, consitent with erythema nodosum, and a biopsy from the mediastinal lymph node revealed a pathology consistent with sarcoidosis. This is the first case of Lofgrens syndrome confirmed by histology ir, Korea.

Sjogren's syndrome is a chronic autoimmune disorder characterized by lymphocytic infiltration of the lacrimal and salivary glands, leading to dryness of eyes (kerato-conjunctivitis sicca) and mouth (xerostomia). The skin lesions in Sjogren's syndrome are usually manifested as xeroderma, but sometimes appear as annular erythema or vasculitis. Central nervous system symptoms may be presented as one of extraglandular manifestations, though rare in incidence, and need differential diagnosis from multiple sclerosis. We report a case of a 45-year-old woman diagnosed as multiple sclerosis at first but later as neurologic manifestation of primary Sjogren's syndrome, showing signs of multiple sclerosis and cutaneous erythematous lesions.

Idiopathic atrophoderma of Pasini and Pierini is a form of dermal atrophy of unknown etiology, usually affecting women during their adolescence and young adulthood. A 2-yr-old girl was presented with erythematous atrophic lesion on the right shoulder, which appeared from birth. The histologic findings were consistent with atrophoderma. This patient, to the best of our knowledge, is the first case of atrophoderma with an onset since birth.

Leprosy is a chronic granulomatous infection caused by Mycobacterium leprae, which primarily affects the skin and peripheral nerves. In this article, we present a 45-year-old man and a 39-year-old women who suffered from asymptomatic irregular erythemas on their trunk and extremities. Since both patients denied the history of exposure to leprosy patients and were absent clinical signs of superficial sensation dysfunction and enlarged peripheral nerves, they were diagnosed of mycosis fungoides and livedo reticularis clinically. Nevertheless the biopsies of erythemas showed perineural and periadnexal foamy-cell granulomas in the dermis and Fite staining revealed a large number of acid-fast bacilli. A diagnosis of multibacillary leprosy was made finally. These cases revealed that since leprosy is still epidemic in some remote area in China and in other developing countries and its clinical manifestations may be very weird sometimes, the dermatologists should be alert of it and skin biopsy could confirm the diagnosis.

Lyme disease is a vector-borne infection, primarily transmitted by Ixodes ticks, and caused by Borrelia burgdorferi. It has a wide distribution in the northern hemisphere. In Korea, however, only one human case has been reported, although B. burgdorferi was isolated from the vector tick I. persulcatus in the region. A 60-year-old male and a 45-year-old female developed the clinical sign of erythema migrans. Each patients were bitten by a tick four weeks and five weeks, respectively, before entering the hospital. On serologic examination, significantly increased IgM and IgG antibody titers to B. burgdorferi were observed in consecutive tests performed at an interval of two weeks. They responded well to treatment with tetracycline.

BACKGROUND: Cutaneous manifestations of vasculitis can be seen as pleomorphic lesions; purpura, erythema, nodule, bulla, ulcer and so on. In cases of polyarteritis nodosa (PAN), cutaneous presentations of small artery pathology may be seen in about one fourth among those patients with systemic form of PAN, and in all cases of cutaneous form subset. OBJECTIVE: To examine the pattern or morphology of cutaneous lesions found in the skin (especially on the lower legs) among Korean patients with cutaneous form of PAN. Patients AND METHODS: Eight patients with diagnosis-confirmed cases of cutaneous PAN were examined regarding the patterns of cutaneous lesions, as well as possible local symptoms, distributions, duration, and any positive findings in laboratory examinations and systemic review. RESULTS: Clinical patterns of cutaneous lesions observed in the lesional areas among those 8 patients were mottled or atypical reticular erythema (5 cases), subcutaneous nodules (3 cases), scattered erythematous patch (3 cases), ecchymotic erythematous patch (3 cases) and superficial ulcer (1 case). Tenderness was detected at the nodular lesions; predilection site were shin and calf areas; a few laboratory abnormalities and systemic symptoms were found regardless of the duration of skin lesions. CONCLUSION: Common clinical patterns of cutaneous lesion recognized with 8 patients of cutaneous PAN were mottled/atypical reticular erythemas, subcutaneous nodules, erythematous/ecchymotic patches, and these in all cases were seen at the lower legs. In patients with each different clinical presentation, there were no relevancies between the duration and severity of the disease.

A 42-year-old woman with systemic lupus erythematosus (SLE) has had wide-spread erythemas with some purpuric patches on her trunk and upper extremities during exacerbation of her disease. Biopsy findings from erythematous lesions and purpuric areas revealed the pathology of lupus erythematosus and leukocytoclastic vasculitis (LCV) with immune deposits, respectively. A feature of wide-spread symmetrical erythemas with foci of LCV occurring in this patient is considered to be an unusual presentation.

Acute gastric mucosal lesions (AGM lesions) is a general term applied to conditions characterized by the acute development of mucosal lesions in the form of erythema, mucosal hemorrhage, erosions and ulcerations in the mucosa of the stomach and duodenum. Although the pathopphysiological events leading to the formation of these lesions remain unknown, we do know that they are after preceded by one of many situations. It has become traditional to use the term stress ulcer to describe AGM lesions proceded by a major stress such as that of an operation or of severe thermal burns or hemorrhagic shock. The silent clinical manifestation of acute gastric mucosal lesions, regardless of their cause, is bleeding. AGM lesions were experimentally produced by brain injury and administration of steroid. This experimental study was conducted in order to study the so called AGM lesions, especially on production and pathology of them. This experimental animals, normal adult rate, were divided into 4 groups the first group of brain injury, the second group of brain injury and administration of steroid, the third group of administration of steroid only, and the fourth group of normal control with administration of normal saline and normal rats. The frequency of AGM lesions was studied in relation to each experimental group, experimental period and grade of lesions. The AGM lesions were divided into 3 grades depending on the macroscopic and microscopic findings. 1. AGM lesions were observed in 34 out of 63 all experimental animals except for control group of animal. Majority of the lesions were found in the glandular portion of the stomach. 2. In the brain injured group, the lesions that was erythematous and superficial mucosal erosion were found in 3 out of 21(14.3%), which were observed only in experimental period of 3-5 days. 3. In the group with brain injury and steroid administration, the lesions were found in 16 out of 21 animals(76.2%) among them grade 1 was in 2 out of 16, grade 2 in 10 and grade 3 in 4, which observed in the period of 2-7 days. 4. In the group with administration of steroid, the lesions were found in 15 out of 21 animals(71.4%), among them grade 1 was 2 out of 15, grade 2 in 11 and grade 3 in 2, which started to be observed form 2nd day through out the experimental period. 5. No lesions were investigated in the control group. No correlation between the variety of brain injury and production of AGM lesion was studied.
