BACKGROUND: Hydrofluoric acid burns are occuring with ever-increiisir g frequency due to the wide use of this acid in industrial fields, such as electronics and semiconductor i idustries. OBJECTIVE: The purpose of thie study was to evaluate the clinical charateristics of hydrofluoric acid burn. This study will give basic information of hydrofluoric acid burn to the dermatologists who are not familiar with hydrofluoric acid. METHOD: Twenty-two patient who were diagnosed as having hydroiluiiric acid burns at koryo General Hospital(1986-1993) were irraluated clinical)y. Forteen were malc ar d eight were female, most of them were in their third decade. RESULTS: The results are sumrnurised as follows 1. Latent periods were variabie from 30 min. to 3 days. Most patients recognized their chemical burn several hours after exposure. 2. Foot & sole (9 cases) and fingers (7 cases) were most frequently in olved. In 7 cases, nails were also involved. 3. Pain was the most. commori iuobjective symptom. 4. Skin lesions showed erytherna, erythematous swelling, erosion, bulla., necrosis, pigmentation and crust, formation, progressii ely. 5. Treatment Wet dressing with Hyami-solution and topical application of ai tibiotics or steroidointment were sufficient in mild case. In severe cases, intralesional injection of calcium glucoante was perfirmed. Debridement was also performed after the progn ssion of tissue damage stopped. Nails were extracted in cases involving nails. CONCLUSION: Hydrofluoric acid burn is characterized clinically by severc progessive tissue destruction and excruciating pain. Dermatologists need to be aware of the clinical features of hydroclucric acid burn and its proper treatment.

We report a case of anosacral cutaneous amyloidosis in a 74 year-old-man. The skin finding is a patch of the size of a childs palm on the sacral area, consisting of brownish macular lines that radiate frorn the anus. Histopathology revealed defiosits of homogenous eosinophilic mateial s in the papillary dermis. Congo red staining and dylon staining was positive. Immuohistochemical staining using anti SAP antibodies and anti-keratin antibodies showed positive reactions.

Calciphylaxsis is a rare and life-threatening condition of progressive cutaneous necrosis secondary to calcification of small and medium-sized blood vessels. It is seen almost exclusively in patients with end-stage renal disease, in a setting of secondary hyperparathyroidism and hypercalcemia resulting in metastatic vascular calcification, We experienced a case of calciphylaxsis manifested with chara- cteristic cutaneous lesions that began as tender violaceous livedoid discolorations and subsequent ulceration on the proximal aspect of the extremities and on the lower part of the abdomen. Histologically, calcification is found in small and medium-sized blood vessels in the deep dermis and subcutaneous tissue. The patient had been treated for hypercalcemia, not complicating renal failure, but the cause of hypercalcemia was not found. However, the hypercalcemia was contolled and the skin lesions also improved after oral prednisolone therapy. Our case is a rare presentation of calciphylaxsis in the absence of renal failure, reversibly improved.

The recent introduction of chemotherapy in the treatment of gynecological malignancies has gained wide acceptance along with prstoperative and prostperative adjuvant therapy and with preradiation and concurrent chemoradiation therapy. But, the side effects of chemotherapy including bleeding and infection due to, bone marrow suppression have reaulted in delayed treatment and a reduction in the chemotherspeutic agent used. Recent efforts overcome this bone marrow suppression have led to development of the various human colony-stimulating factor indluding recombinant granulocyte colony-stimulating factor. The author investigated the clinical benefita and toxicity of G-CSF used during chemotherapy of various gynecological malignancies at the Departent of Obstetrics & Gynecology at Hanyang University between August, 1991 and July, 1992. The results were as follows ; 1. An increase in the number of neutrophils following a single injection of G-CSF was noted in 19 out of 21 cases(600~1,000/mm3 before injection, 4,500~12,000/mm3 after injection). The remaining 2 cases showed an increase after 3~5 continuous injections. 2. To assess the increase in neutrophils according to the dosage of G-CSF given, 100 and 300microgram/m* of G-CSF were injected in each trial of chemotherapy in a single case of ovarian cancer. The results were a 1.5 time increase when injected when injected with 300microgram/m*. 3. After injecting into a patient with recurrent endometrial cancer who was managed with 15gm of ifosfamide, 50gm of cis-platinum, 50gm of adriamycin and 3gm of mesna following surgery, no evidence of neutropenia could be found after 4days of prophylactic G-CSF injections. 4. Patients with cervix cancer with metastasis to the lung were first treated with GM-CSF in one trial and G-CSF in the nest. Patients treated with Gm-CSF for a period of 7 days showed leukocytosis(3,600/mm3) but the number was reduced to 1,400/mm3 after 7 days. On the other hand, patients treated with G-CSF showed an increase of 5,700/mm3 within one day and this figure did not decrease until 20 days later. 5. The toxic effects of G-CSF included on case of severe back pain was easily managed by administration acetaminophen. Others were headache, chills, general weakness and redness of the oral mucosa and injection area. Most of these symptoms disappeared within 2 days. The G-CSF is effective in neutropenia during chemotherapy thereby decreasing the incidence of treatment delay or dose reduction. It also increases the amount of chemotherapeutic agent administered and its toxicity is more tolerable making a rigid systemic chemotherapeutic regime possible.

We reviewed the 43 medical records of patients with cellulitis or erysipelas who had been admitted at the depar1ment of dermatology of Seoul National University Hospital and followed them up for mean 21.6 months. The results were as follows. 1. The sex ratio of patients with cellulitis was 1:1.4 and the average age was 49 years. 2. The lower extremity as the most frequently invloved site of cellulitis with the frequency of 58.1% (25 cases), with the head and neck being involved in 16 cases(37.2%) and trunk and upper extremity in 1 case each(2.3% ). 3. The portals of infecticin were suspected in 33 cases(76% ), where tinea pedis was detect,ed in 18 cases(41.9%), previous skin infeection 10 cases(23.3%) and trauma in 9 cases(20.9%). 4. Initial systemic symptoms were fever(76.7%), chill(65.1%) and headache(37.2%). Erythema(100%), local heating(90,7%), tenderness(88.4%), swelling(86.0%), ulcer(16.3%), bulla(14.0%), lymphangitis(9.2%) and lymphadenit,is(9.2%) were found in the skin lesions. 5. The laboratory findings revealed leukocytosis in 35.7%, elevaed ESR in 86.8% positive 6. ASO titer in 63.0% and positive CRP in 80%, Microorganism. were detected in only 1 of 15 blood cultures, in 2 of 4 bulla fluid cultures and in 7 of 9 bus cultures. There was no growth of causative microorganisms in 3 tissue cultures and 9 saline needle aspiration cultures. Penicillin was used as primary antibiotics in 19 cases, which changed to another antibiotics due to lack of improvement in 3 cases and cefazolin was used in 21 cases, which changed in 2 cases due to the same reason. 7. Average admission priod was 11 days(range from 3 to 20 days) and 30.2% of patients wit.h cellulitis experienced recurrence, but 48% on low extrernity in contrast with 6.7% on head and neck.

S-100 protein is a mixture of three proteins, that is, S-100 ao(aa), S-100 a(ab) and, S- 100 b(bb). Twenty-two case, of sweat gland tumors were stained with immunoperoxidase technique (ABC method) for the presence of S-100a and b-subunit. Four syringomas, four eccrine poromas, two eccrine porocarcinomas, two ecerine spirdeiomas, one papillary eccrine adenoma, three clear cell hidradenomas, three mixed tumr rs of the skin, two papillary syringocystadenomas, and one cylindroma were included. All specimens were formalin-fixed and paraffin-embedded. The results were as follows : 1) The staining patterns of anti-S-100a and b-protein antibodies we e simillar to those of anti-S-100 protein antibody except in eccrine poroma and porocare nomal. 2) In eccrine poroma and porocarcinoma, scattered S-100-positive dendritic cells within tumor cell nests were stained by S-100-protein antibody (3/6), but not by anti-S-100a protein antibody. S-100p is present in normal Langerhans cells. Therefore this finding suggests that these cells niay be Langerhans cells
