From January 1984 to June 1991, we studied testicular relapsed patients among 105 cases of acute lymphocytic leukemia in children who were admitted to the Department of Pediatrics and Yonsei Cancer Center, Yonsei University Severance Hospital. The results were as follows: 1) 15 out of 105 (14.4%) cases of acute lymphocytic leukemia were diagnosed as testicular relapse. According to the prevalence by the age groups, there were no patient under 2 years old, 14 out of 73 (19.4%) in 2~9 years old and 1 out of 26 (3.8%) over 10 years old groups. 2) At initial diagnosis of acute lymphocytic leukemia there were significant correlation between testicular relapse and initial lymphadenopathy (p=0.09), but not with WBC count, hemoglobin level, platelet count, hepatomegaly and splenomegaly. 3) Mean duration to testicular relapse from initial diagnosis of acute lymphocytic leukemia was 3.1+/-1.7 years. 4) Among 15 patients, 7 cases combined with bone marrow or central nervous system relapse. Their survival rate was lower than isolated testicular relapse groups. 5) The 5 years survival rate of testicular relapsed patients was 67% after the combinations of chemotherapy, radiotherapy and orchiectomy.

BACKGROUND: Hemorrhagic fever with renal syndrome is a serious health problem in Korea. Formalin inactivated mouse brain-derived Hantaan virus vaccine (HantavaxR) has been available since 1990 and recom-mended in national immunization programs for children and adults by the health authority. However, Hantavax has not been evaluated for efficacy in a randomized, placebo-controlled clinical trial and data on neutralizing antibody responses in human trials are limited. To investigate humoral immune responses to Hantavax, we studied volunteers immunized according to the recom-mended two dose schedule. METHODS: With informed consent, 30 healthy adults were immunized with two doses of Hantavax (Lot No. 6001, 2360002) 0.5ml given intramuscularly on deltoid muscle 4 weeks apart. The monovalent vaccine, pro-duced from the ROK 84-105 strain, is inactivated with 0.05% formalin and has an ELISA antigen titer of 4096. Sera were collected before vaccination and 4 weeks after each dose for a total of 90 serum samples from 30 vaccinees. Neutralizing antibodies were measured at Unit-ed States Army Medical Research Institute of Infectious Disease (Ft. Detrick, MD) in plaque reduction neutrali-zation tests. Antibody titers were expressed as the highest serum dilution that reduced the standard viral dose (45 ~ 58 plaque forming units of Hantaan virus strain 76-118 by 50 percent. Serum binding antibodies also were mea-sured in a high density particle agglutination test (Hanta-dia R) at Yonsei University. RESULTS: Neutralizing antibodies were detected in only 5 of 30 vaccinees given two doses of Hantavax, yielding seroconversion rate of 16.7%. The endpoint titers of reactive sera were 1:320, 1:10, 1:10, 1:10, and 1:40 respectively. The seroconversion rate measured by high density particle agglutination test was 80.0% (24/30). CONCLUSION: These results indicated that the poor neutralizing antibody response observed in this study suggests that further evaluations of the protective effi-cacy of inactivated mouse brain-derived Hantaan virus vaccine against HFRS.

A 37-year-old man presented with a 1-year history of asymptomatic ill-defined subcutaneous thickening with overlying whitish hairs on right occipital scalp. Histopathologic examination from this subcutaneous mass revealed neurofibromatous tissue with a diffuse infiltrative growth. S-100 protein staining showed decreased melanocytes and melanin in hair follicles. He was diagnosed as a diffuse neurofibroma associated with poliosis. To our knowledge, only two cases of poliosis associated with neurofibroma have ever been reported in English.

We report a case of a 67-year-old man presenting with a 2-week history of erythematous zosteriform indurated confluent nodules and plaques on the right chest which was affected by a herpes zoster infection one month ago. The previous history revealed an adenocarcinoma with malignant pleural effusion on the right lung (stage IV, T4N1M1) 3 months ago. Histopathologic findings showed tumor cells infiltrated throughout the dermis, forming focal glandular structures. We think that the case was the isotopic response in the form of an occurrence of a new skin disorder at the site of another unrelated and already healed skin disease. Many cases of isotopic response have been reported in Korean literature such as lichen planus, granuloma annulare, benign fibrous histiocytoma and reactive perforating collagenosis occurring on the healed site of herpes zoster infection. This is the first report of cutaneous metastatic carcinoma as an isotopic response in Korea.

Bullous pemphigoid (BP) is an acquired autoimmune disease that's characterized by subepidermal vesicles and bullae. The etiology for BP is mostly idiopathic, but numerous observations have suggested the role of certain drugs in the occurrence of bullous pemphigoid. Drugs such as penicillamine, furosemide, captopril, enalapril, sulfasalazine and ampicilline have been reported to be associated with bullous pemphigoid. We report here on a new case of bullous pemphigoid that was probably induced by ticlopidine (thienopyridine, adenosine diphosphate receptor inhibitor) in a 78 year old female patient.

BACKGROUND: Cheilitis is a common problem, the cause of which is often obscure. OBJECTIVE: We evaluated the frequency of allergic contact cheilitis and irritant contact cheilitis among 23 eczematous cheilitis patients via patch testing and assessment of past medical history. METHODS: This study consisted of 23 patients with eczematous cheilitis who had visited the Department of Dermatology, two University Hospital in Incheon, between January 2005 and August 2006. Of the 23 patients, 20 were female, and the age range was 15 to 70 years. We analyzed the clinical characteristics (age, gender, duration, atopic or allergic disease, lip licking) of the patients. All patients were patch-tested with the Korean standard series, 9 patients with the Cosmetic series and 5 patients with as is test. We then analyzed the results of the patch tests and evaluated the relevance of any positive results. RESULTS: Of the cases, 34.78% were identified as irritant contact dermatitis (ICD), and 30.43% as allergic contact dermatitis (ACD). Furthermore, of the 23 patients, 11 were positive to one or more antigen and 7 of these had a clinical relevance for positive antigen. The substances causing a positive reaction, triggering ACD were identified as medicaments applied to the lip, lipstick ingredients and toothpaste. CONCLUSION: The most common cause of cheilitis was irritation, frequently caused by lip licking. But, almost one third was caused by ACD. Patients with chronic eczematous cheilitis should be patch-tested to identify the materials causing ACD.

Acrokeratosis paraneoplastica, or Bazex syndrome, is one of the paraneoplastic syndromes. The characteristic skin lesions include palmoplantar keratoderma, psoriasiform skin lesions, hyperpigmentation, and nail dystrophy. The most common associated neoplasms are squamous cell carcinoma of the upper respiratory tract and other kinds of tumors with cervical lymph node metastasis. A 63-year-old woman presented with an 11 month history of hyperkeratotic lesions on the palms and soles. Ten months before she had been diagnosed with adenocarcinoma of the colon and undergone a left hemicolectomy. We report a case of acrokeratosis paraneoplastica associated with colon cancer which persisted after removal of the primary cancer, but resolved with topical tretinoin treatment.

Corals are the marine organism that belongs to the phylum Cnidaria, and are one of the common causes of superficial injury in the marine environment. In addition to acute reactions such as burning or stinging pain and erythema, coral injuries may present with complications such as foreign body reactions, bacterial infections, and/or localized eczematous reactions. A 23-year-old male presented with an erythematous edematous tender patch with centrally grouped vesicles on the left ankle; the injury had occurred during skin-scuba diving 2 days before. A biopsy of the lesion treated with hematoxylin-eosin stain showed epidermal necrosis with subepidermal blisters and neutrophilic panniculitis. Herein we report a case of cellulitis caused by the nematocyst stings of corals.
