Aquagenic urticaria is a rare form of physical urticaria in which wheal is produced by contact with water. A 21-year-old woman was referred to our department because of itching wheal after contact with water for 1 month. Match-head-sized wheal surrounded by bean sized erythema was provoked with water on her face regardless of its tempera ture, osmolarity and quality. Passive transfer test was negative. Result of pro vocation test with normal saline and NaHCO solution, which was reported to be therapeutically effective, was similar to those with pure water.

Kimura's disease is a chronic inflammatory condition of unknown cause. It usually appears as a painless nodule in the head and neck region often associated with regional lymphadenopathy, but there have rarely been reports of penile involvement or clinical presentation as an ulcerative plaque. We present a case of Kimura's disease occurring on the penile shaft as an ulcerative plaque in a 44-year-old man. A vesicular eruption had occurred on his penile shaft followed by an ulcerative plaque for 2 months. He had suffered from recurrent regional lymphadenopathy for 15 years and he had also exhibited intermittent eosinophilia. Histopathologic findings revealed diffuse eosinophilic infiltration in the dermis of the skin and eosmophilic abscesses in the lymphoid follicles of the mguinal lymph node. After short-term systemic steroid therapy and local injection of triamcinolone acetonide, the ulcerative plaque was healed.

Benzene and toluene, which are widely used aromatic hydrocarbons in workplace, are recently proved to cause health hazards due to their toxic effects. This study investigated the influence of toluene on the urinary excretion of benzene metabolite by administering short term exposure limit(STEL) of these compounds(i.e., 13.8mg/kg of benzene and 108.8mg/kg of toluene) intraperitoneally into Sprague-Dawley rats. After administration, urinary phenol concentration of rat was measured by gas chromatography for every three hours. Data were analyzed by non-parametric statistical methods using Kruskal-Wallis multi-sample test and Mann-Whitney U test. The following results were obtained: 1. Administration of STFL-benzene increased urinary phenol concentration in rats. 2. Urinary phenol concentration was increased logarithmically according to the dosage of benzene. 3. Excretion of phenol in urine was decreased when benzene and toluene were administered simultaneously compared with administering benzene alone. In Summary, these results reveal that administration of STEL of toluene has antagonistic effect of urinary excretion of benzene metabolite in rats.

BACKGROUND: Quinidine appeared to increase serum digoxin levels when given with quinidine. Therefore elevated serum digoxin concentrations and clinical toxicity have been reported in patient receiving quinidine. Currently, Bayesian method which estimates the most probable parameters of the drug for each patient from population parameters data is useful approach for adjusting digoxin dosage. To increase the accuracy of Bayesian method, it is desirable to use population parameters of Korean. Therefore we evaluated the effect of quinidine on digoxin clearance in Korea. METHOD: Patient's records from 19 adult cardiac disease without CHF having normal renal and liver function from Seoul National University of Hospital respectively wre evaluated. Digoxin pharmacokinetic parameters, CL and Vd, were obtained from serum concentration of digoxin of single and combined therapy at each steady-state by using bayesian method. RESULTS: This study show that quinidine reduced the total body clearance of digoxin from 2.39+/-0.17 to 1.51+/-0.08ml/min/kg(p<0.05) and reduced the digoxin volume of distribution from 8.57+/-0.29 to 4.98+/-0.19L/kg(p<0.05). This results show that digoxin dosage reduced to 40-50% in Korean, if quinidine therapy is initiated.

Squamous cell carcinoma of the skin arises mostly in the head and neck regions, less frequently in the rest of the body, and rarely in the palms and soles. We report a case of a 6S-year-old man who had had time-sequential development of multiple squamous cell carcinomas on his palms and soles for the past 12 years. These lesions were, in order of time, ulcerative nodules, ulcerative hyperkeratotic papules, hyperkeratotic plaques, maceratied plaques, dark discolored patchs, and hyperkeratotic papules. They were treated by total excision and cryotherpy apart from the last squatnous cell carcinoma in 1994.

Pearly penile papules are small, smooth, dome-shaped, grayish to skin-colored papules, that are arranged in one or several rows. These are commonly located circumferentially on the corona and sulcus of the glans penis. A 36-year-old male patient had had asymptomatic numerous pearly smooth 1 * 1mm -sized dome-shaped papules for several months. A Histopathological examination revealed an increased number of fibroblasts on the papillary dermis, vascular proliferation and a mild lymphocytic infiltration. We diagnosed the condition as pearly penile papules. No treatment other than reassurance was given. We report, herein, a case of pearly penile papules.

We reported a case of nevus sebaceus associated with trichilemmoma in a 19-year- old female patient. The lesion was a 2 x 2 cm sized yellowish verrucous plaque with two 0.3 x 0.3 cm sized dome-shaped papules. Histopathological examinat,ion revealed hyperkeratosis, papillomatosis and acanthosis, proliferation of sebaceus glands, presence of apocrine gland and mild inflammatory cellular infiltration around superficial vessels. In the epidermis of the lesion, there were two foci of lobulated mass consisted of clear cells with columnar basal cells and thick basement membrane.

BACKGROUND: The pathogenesis of pilomatricoma is unknown. Several reports have suggested that apoptosis may play a role in the pathogenesis of pilomatricoma. As the bcl-2 and p53 are well-known regulators of apoptosis, a disturbance in either bcl-2 or p53 could compromise a proper apoptotic response and relate to the development of the tumor. OBJECTIVE: The purpose of this study was to evaluate the expression of bcl-2 and p53 proteins in pilomatricoma. METHODS: Paraffin blocks of 14 cases of pilomatricoma were stained immunohistochemically by using anti-bcl-2 and anti-p53 antibodies. RESULTS: 1. Histologically, SCs were found in all 14 pilomatricomas, while BCs and TCs were found each in 9 tumors. 2. All the SCs found in 14 tumors and all the TCs found in 9 tumors were unstained for both bcl-2 and p53. 3. The expression of bcl-2 in 9 tumors was variable. Basal BCs showed reactivity from negativity(-) to strong positivity(+++) and suprabasal BCs showed reativity from negativity(-) to moderately strong(++) positivity. Both basal BCs and suprabasal BCs showed negativity for bcl-2 in 3 tumors and similar positive staining in 1 tumor, while basal BCs showed stonger positivity than suprabasal BCs in 5 tumors. 4. The expression of p53 in 9 tumors was also variable. Both basal BCs and suprabasal BCs showed reactivity from negativity(-) to moderately strong positivity(++). Both basal BCs and suprabasal BCs showed negativity for p53 in 1 tumor and similar positive staining in 6 tumors, while suprabasal BCs showed stronger positivity than basal BCs in 2 tumors. CONCLUSION: The above immunohistochemical findings showed that the expression of bcl-2 and p53 was variable and suggest that both bcl-2 and p53 have a limited role in the control of apoptosis in pilomatricoma.

We report a case of clear cell acanthoma occurred in a 61 year old man. He developed a brownish bean sized nodule on the left chest 3 years ago. The skin lesion has slowly increased in size without any subjective symptoms. Histopathologic examination revealed proliferation of clear cells within a sharply demarcated area of the epidermis. The presence of numerous neutrophils throughout the epidermis were also noted.
