Pterygium inversum unguis (PIU) is a rare nail abnormality in which the distal nail bed adheres to the ventral surface of the nail plate, with obliteration of the distal groove. Because of the rarity of this condition, its exact origin is unknown. This disorder can be either congenital or acquired, with or without a family history. The acquired forms may be idiopathic or secondary to systemic connective tissue diseases or other causes such as stroke, neurofibromatosis, leprosy, or the use of nail fortifiers. We present an unusual case of acquired idiopathic PIU of the 10 fingernails in a 22-year-old man.

PURPOSE: This study was to identify the effect of the experience of diabetes education on knowledge, self-care behavior and glycosylated hemoglobin (HbA1C). Further, this study was held to examine about patient's preferred methods of education and re-education frequency. METHODS: 166 type 2 diabetes patients from two hospitals in Incheon participated in this study. Data were analyzed by using descriptive analysis, t-test, ANOVA, Scheffe's test and multiple regression analysis. RESULTS: 72.3% patients needed re-education and the average interval of re-education was 8.53 months. Patients preferred education methods were lectures, practical training, and studying from pamphlet. Depending on the frequency of diabetes education, there were significant differences in the level of diabetes knowledge (F=10.88, p<.001) and self-care behaviors (F=4.59, p=.012), but there was not significant difference with HbA1C (F=1.53, p=.220). As to how much the diabetes education helped managing diabetes, there was a significant difference in the level of self-care behaviors (t=2.01, p=.049), but there were not significant differences in level of knowledge (t=1.10, p=.275) and HbA1C (t=-.33, p=.746). The experience of diabetes education was a significant factor which influenced patient's knowledge (t=3.93, p<.001) and self-care behaviors (t=2.21, p<.001). But HbA1C was not influenced by the experience of diabetes education (t=-1.68, p=.096). CONCLUSION: It is necessary to provide diabetes education with appropriate interval and methods and subjects that reflect the needs of patient through the study results.

Leukemia cutis (LC) is defined as a neoplastic leukocytic infiltration of the skin. Few clinical studies are available on recent trends of LC in Korea. The purpose of this study was to analyze the clinical features and prognosis of LC in Korea and to compare findings with previous studies. We performed a retrospective study of 75 patients with LC and evaluated the patients' age and sex, clinical features and skin lesion distribution according to the type of leukemia, interval between the diagnosis of leukemia and the development of LC, and prognosis. The male to female ratio was 2:1, and the mean age at diagnosis was 37.6 yr. The most common cutaneous lesions were nodules. The most commonly affected site was the extremities in acute myelocytic leukemia and chronic myelocytic leukemia except for acute lymphocytic leukemia. Compared with previous studies, there was an increasing tendency in the proportion of males and nodular lesions, and LC most often occurred in the extremities. The prognosis of LC was still poor within 1 yr, which was similar to the results of previous studies. These results suggest that there is a difference in the clinical characteristics and predilection sites according to type of leukemia.

The incidence of overall cancer has increased over time. The incidence of top-ranking cancers has changed in the 1990s and the 2000s. However, few studies have evaluated the trends in metastatic skin cancers during this period. We evaluated the recent trends in incidence, peak age and location of metastatic skin cancers from 1991 to 2010. This 20-yr survey was divided into two decades to determine the trends by comparing the statistics. Out of 694,466 outpatients (1991-2010), 174 (0.025%) were diagnosed with metastatic skin cancer. The incidence of metastatic skin cancer increased significantly from 20.64 per 100,000 outpatients in the 1990s to 28.70 per 100,000 outpatients in the 2000s (P = 0.030). The peak age of skin metastasis shifted from the 40s to the 50s in women, and from the 50s to the 60s in men. The percentage of metastatic skin cancers originating from intra-abdominal organs increased from 10% in the 1990s to 23.1% in the 2000s (P = 0.027). The percentage of metastatic skin cancers located on the abdomen increased from 7.1% in the 1990s to 15.4% in the 2000s (P = 0.011). The higher proportion of metastatic skin cancers located on the abdomen may be related to the increase in skin metastases from intra-abdominal organs.

BACKGROUND: Many pigmentary disorders can be manifested as linear streaks of hyperpigmentation, along the Blaschko's line. These include progressive cribriform and zosteriform hyperpigmentation (PCZH) and linear and whorled nevoid hyperpigmentation (LWNH). There have been debates on the universally accepted diagnostic criteria differentiating these disease entities. OBJECTIVE: To determine the clinicopathologic characteristics of hyperpigmentation along the line of Blaschko and to examine the acceptability of PCZH or LWNH criteria as a diagnostic tool for differentiating these diseases. METHODS: A retrospective study was conducted on 13 patients who presented with linear hyperpigmentation along the Blaschko's line. The patients' clinicopathologic characteristics were analyzed and matched with the PCZH/LWNH diagnostic criteria. RESULTS: Age of onset widely ranged from birth to 61 years, but predominantly before the age of 4 years. The male-female ratio was 1:1.2. Trunk was the most common site of involvement. Histologic examination commonly showed a basal layer hyperpigmentation in all patients and pigmentary incontinence was observed in 2 patients. Four patients who satisfied all the diagnostic criteria for PCZH also fulfilled the diagnostic criteria for LWNH, except for the timing of onset. An additional 4 patients satisfied all the diagnostic criteria for LWNH and also fulfilled the diagnostic criteria for PCZH, except for the timing of onset. Excluding the age of onset criteria, the other 3 patients fulfilled both diagnostic criteria for PCZH and LWNH. CONCLUSION: These results demonstrate that PCZH and LWNH should not be considered as a different disease entity and that supports the idea that these are part of the same disease spectrum.
