Subcorneal pustular dermatosis is a chronic, benign, relapsing pustular eruptions characterized histologically by subcorneal pustules which contain abundant neutrophils. We report a case of subcorneal pustular dermatosis occured in a 71-year-old male with typical climcal lesions. Biopsy of a pustule showed a subcorneal cavity with numerous neutrophils, which were also scattered throughout the Malpighian layer below. The result of imrnunofluorescent studies was negative. His eruption is controlled by DDS (25-100mg daily) but the eruptions recur quickly on sessation of the drug.

Verrucous carcinoma, a distinct variant of well differentiated squamous cell carcinoma, was originally described as an entity by Ackerman. This histologically benign lesion features relentless local growth and little tendency to metastasize. The commonest location of verrucous carcinoma is the oral cavity. Less frequently, the tumor originates in the squarnous mucosa, skin of the genitalia(glans penis, vulava, vagina, scroturn and perineum), nasal fossa, the larynx or the sole. Now we report a case of verrucous carcinoma developed on the retroauricular area in a 49-year-old man. He was treated by surgical excision followed by skin graft. This appears to be the first reported case arising on the retroauricular area.

Studies on epidemiological aspects of contact dermatitis have been published in recent years since the introduction of standardized method of patch test.However, most previous epidemiologic reports studied patients with allergic contact dermatitis in hospitals with patcb testing. Such data are not directly applicable to the population at large. Very recentiy there are a few reports ahout rates of exposure and patch test reactivity to certain antigens in a general population. which is difficult to be applicable in a developing country at present. With regard to this, we have tried to analyze the contact dermatitis questionaire containing various items of common causative agents producting contact dermatitis (for example, metals, cosmetics, plants, medicaments and rubber etc.) for the detection of past contact dermatitis histories in a total new dermatologic outpatients. A11 2258 dermatologic outpatients entered this study including 303 contact dermatitis patients (allergic contact dermatitis, primary irritant dermatitis and housewife eczema). We also analyzed the patch test results of 107 patients with suggesting contact dermatitis who visited our hospital at the same period of collecting questionaires. The study results were as follows. 1. Positive rate of each item of the questionaire (No. of said Yes/ No. of responders) was metals, 10.4% cosmetics, 31.8%, plants, 18.2%; medicaments, 12.4%; rubber, 5.8%; and others, 11.7%. 2. The most common all regens of the patch test positive reactions were nickel sulfate (9.3%), fragrance mix(9.3%), formaldehyde(6.5%), potassium dichromate (5.6%), neomycin sulfate (5.6%), balsam of Peru (4.7%), cobalt chloride(3.7%), wood tar(3.7%) and paraphenylene diamine (2.8%) in order of frequency. And the patch test positive rate of commercial cosmetic products was 10.3%. In conclusion, cosmetics, medicaments, metals, plants and rarely rubber are found the most common etiologic agents of contact dermatitis in this study. The reasons and back-ground of the results were also discussed in various aspects.

OBJECTIVE: To investigate the relationship between respiratory muscle strength and cardiac function in patients with Duchenne muscular dystrophy (DMD). METHOD: This study included 37 patients with DMD. Cardiac function of patients was evaluated by thoracic echocardiography, which recorded left ventricular ejection fraction (LVEF). Maximal expiratory pressure (MEP) and maximal inspiratory pressure (MIP) representing respiratory muscle strength and blood sampling for brain natriuretic peptide (BNP) were performed. RESULTS: LVEF did not show significant correlation with MIP, MEP or age. However, LVEF was negatively correlated with BNP level. CONCLUSION: Cardiac dysfunction of patients with DMD didn't correlate with age or respiratory muscle strength. Therefore, investigation of cardiac function itself is needed for patients with DMD irrespective of respiratory compromises.

Background/Aims: Owing to the low prevalence of small-bowel adenocarcinoma (SBA), data on the impact of Crohn’s disease (CD) on the survival of patients with SBA are lacking. Therefore, we investigated this issue in this study. Methods: In this bicenter cohort study, patients with histologically confirmed SBA were retrospectively enrolled and classified into two groups: sporadic SBA and CD-associated SBA. Patients with duodenal SBA were excluded. Overall survival, disease-free survival, and factors associated with survival were analyzed. Results: Of 128 patients with SBA, 115 had sporadic SBA and 13 had CD-associated SBA. Ileal involvement and poorly differentiated tumors were more common in the CD-associated SBA group than in the sporadic SBA group (ileal involvement, 53.8% vs 22.6%; poor differentiation, 46.2% vs 14.8%; both p<0.05). In survival analysis, overall survival showed no statistical difference between the sporadic SBA and CD-associated SBA groups (p=0.370). However, when stratified by stage, the adjusted overall survival of the CD-associated SBA group was lower in patients with an advanced disease stage (p=0.029). Disease-free survival showed the same tendency, albeit without clinical significance (p=0.097). CD (hazard ratio [HR], 2.308; p=0.047), older age (≥65 yr) at SBA diagnosis (HR, 2.766; p=0.001), and stage III/IV disease (HR, 3.151; p<0.001) were factors associated with mortality. Conclusions The overall survival of patients with CD-associated SBA did not differ from that of patients with sporadic SBA. However, as CD is an independent risk factor for mortality, vigilant surveillance in high-risk patients may be crucial.

Background/Aims: We aimed to evaluate the clinical characteristics and long-term prognosis of elderly-onset ulcerative colitis (EOUC) in Korean patients over a 30-year period using a wellestablished population-based cohort in the Songpa-Kangdong district of Seoul, Korea. Methods: Clinical characteristics and prognosis were compared between two groups: EOUC,defined as UC diagnosed in individuals aged ≥60 years and non-EOUC (N-EOUC), defined asUC diagnosed in individuals aged 18 to 59 years. Results: We identified 99 patients with EOUC (10.3%) and 866 patients with N-EOUC (89.7%) between 1986 and 2015. During the median follow-up of 104.5 months, the overall exposure tomedications was comparable between patients with EOUC and N-EOUC (p=0.091 for corticosteroids, p=0.794 for thiopurines, and p=0.095 for anti-tumor necrosis factor agents). The cumula-tive risks of disease outcomes were also comparable between patients with EOUC and N-EOUC (22.4% vs 30.4% for proximal disease extension [p=0.351], 11.9% vs 18.1% for hospitalization [p=0.240], and 2.3% vs 1.8% for colectomy [p=0.977]) at 10 years after diagnosis. Multivariate Cox regression analysis revealed that corticosteroid use at diagnosis was an independent predic-tor of proximal disease extension (hazard ratio [HR], 6.216; 95% confidence interval [CI], 1.314 to 28.826) and hospitalization (HR, 11.241; 95% CI, 3.027 to 41.742) in patients with EOUC. Conclusions In this population-based study from Korea, the pattern of medication use seemed comparable between the EOUC and N-EOUC groups. Moreover, patients with EOUC and those with N-EOUC have a similar disease course in terms of proximal disease extension, hospitaliza-tion, and colectomy.

Gastrointestinal involvement has been reported to occur in about 10 to 20% of patients with malignant lymphoma. The most common gastrointestinal site for the lymphoma is the stomach, followed by the small intestine, the ileocecal region and the colon. The esophagus is the least commonly involved gastrointestinal organ, accounting for less than 1% of patients with malignant lymphoma. We describe a case of primary esophageal and small bowel lymphoma presenting with bilateral main bronchial obstruction. The patient was treated with radiation therapy, small bowel segmental resection and combination chemotherapy. We report a case with a review of the relevant literature.
