The authors reviewed 250 cases of tumors in the eye and its adnexa diagnosed histopathologirally at the Department of Ophthalmology, Seoul National University Hospital during the last 10 years (Jan. 1976 - Dec. 1985). The results were summarized as follows: 1. The sex distribution revealed 130 males (52%) and 120 females (48%). 2. The tumors of the eye and its adnexa involved the lid 73 cases (29.2%), epibulbar tissue 72 cases (28.8%), the orbit 56 cases (22.4%), and intraocula. tissue 49 cases (19.6%) in decreasing order. 3. There were 159 cases (63.6%) of benign tumors and 91 cases (36.4%) of malignant tumors. 4. The most frequent malignant tumor of the eye and its adnexa was retinoblastoma, and the most frequent benign tumor was nevus. 5. Of the intraocular malignant tumors, the incidence of retinoblastoma was impressively higher than that of malignant melanoma in Koreans. 6. Of the primary malignant lid tumors, the relative incidence of squamous cellcarcinoma and sebaceous gland carcinoma to basal cell carcinoma in Koreanswas high in comparison with that of Caucasians.

BACKGROUND: The epidemiology of pediatric dermatoses shows a tendency to change as social development and the environment improve. OBJECTIVE: The purpose of this study was to investigate the distribution of pediatric dermatoses in Gwangju, Jeonnam province, and to compare the results with previous reports from the same area (1990~1994). METHODS: New patients under 15 years of age, who visited the Department of Dermatology, Chonnam University Hospital from 2000 to 2004, were reviewed through the clinical records. The results were compared with the previous reports from the same area (1990~1994). RESULTS: Of 25,428 new patients, 4,156 (16.3%) were pediatric patients. There was a male to female ratio of 1.12:1. The ten most common dermatoses were atopic dermatitis (13.0%), verruca (12.2%), vitiligo (7.2%), urticaria (6.2%), epidermal nevus (3.7%), fungal infection (3.5%), eczematoid dermatitis (3.5%), alopecia (2.9%), melanocytic nevus (2.6%) and contact dermatitis (2.6%). In the annual distribution, dermatoses showing an increasing tendency were identified as verruca, alopecia, epidermal nevus and melanocytic nevus. CONCLUSION: The proportion of pediatric dermatoses with viral diseases and cosmetic problems such as alopecia and pigmented nevi appeared to be higher in comparison to the previous report. This might be largely due to the increase of cosmetic interest with accompanying emotional stress at school.

BACKGROUND: There has been no statistical study of dermatoses in the Suwon area and southern area of Kyonggi province which has been rapidly developing in the last 7 years. OBJECTIVE AND METHODS: We evaluated the recent distributions of dermatoses in the Suwon area and southern area of Kyonggi and compared them with the previous reports of other provinces of Korea. Fifty two thousand, one hundred fifty three new outpatients who visited the Ajou University Hospital from 1995 to 2001 were analysed statistically. RESULTS: The study results are summarized as follows: Among the 52, 153 outpatients, the total number of male patients were 24, 005(46.0%) and female patients were 28, 148(54.0%). The frequency of age groups are as follows; the age groups were the 3rd decade(22.0%), 4th decade(20.4%), 1st decade(18.7%), 5th decade(11.5%), 2nd decade(11.1%), 6th(8.5%), 7th(5.4%), 8th and above(2.4%). The distributions of dermatoses as disease groups were eczema(28.6%), dermatophytosis(8.7%), erythema urticaria and drug eruption(8.1%), disease of skin appendages(7.9%), viral infection(7.3%), etc. Those dermatoses which demonstrated a tendency to increase annually were seborrheic dermatitis, hyperpigmentary disorders, verruca, and alopecia areata. The incidence of dermatophytosis, in particular, decreased during the study period. Seasonal distribution showed that those diseases occurring the most frequently during the summer were dermatophytosis, allergic contact dermatitis, urticaria, verruca, and vitiligo. The incidence of atopic dermatitis and nevocellular nevi increased during the winter season. Acne vulgaris was the disease occurring frequently during summer and winter. Sexual distribution of dermatoses showed that hyperpigmentary disorder, nevocellular nevi, benign epidermal tumor, acne, allergic contact dermatitis, and irritant contact dermatitis were more frequent in females, and dermatophytosis, seborrheic dermatitis, alopecia were more frequent in males. Age distribution was as follows; atopic dermatitis, vitiligo and verruca was the most frequent in the 1st decade. Acne vulgaria was the most frequent in the 2nd decade and 3rd decade. Hyperpigmentary disorder and seborrheic dermatitis were the most frequent in the 4th decade. Hyperpigmentary disorder was the most frequent in the 5th decade and herpes zoster in 6th, 7th and 8th decade and above. CONCLUSION: In contrast to an earlier published report from Seoul, the infectious dermatoses, especially parasitic infestation, showed a tendency to decrease and nevocellular nevi, hyperpigmentary disorder and alopecia showed a tendency to increase. The distribution pattern of the skin disease did not differ from other provinces of Korea in general.

BACKGROUND: Pediatric dermatoses can be regarded as a different disease because a child's skin differs from an adult's skin in many aspects. OBJECTIVE: The purpose of this study was to evaluate the distribution of pediatric dermatoses in the Kyonggi-do Ansan area and to compare the results with previous reports. METHODS: New patients under 15 years of age who visited Korea University Ansan hospital from 1998 to 2002 were reviewed using their clinical records. RESULTS: The study results are summarized as follows; Among the 25, 839 new patients, 7, 255 (28.1%) were pediatric patients with a male to female ratio of 1: 1.12. In the age distribution, the number of patients decreased with increasing age. The Peak incidence occurred in August, July and January in decreasing order. The incidence was more prominent in summer and winter. The ten most common dermatoses were atopic dermatitis, viral wart, contact dermatitis, urticaria, molluscum contagiosum, dermatophytosis, vitiligo, hemangioma, nevocellular nevus, and acne in decreasing order. In the annual distribution, dermatoses showing an increasing tendency were identified as atopic dermatitis, viral wart and acne, whereas dermatophytosis showed a decreasing tendency. CONCLUSION: Compared to previously published reports, the distribution of dermatoses was different and the proportion of pediatric patients had decreased according to the reduction of the pediatric population.

BACKGROUND: Eyelid tumors are common neoplasms encountered in daily dermatology practices and encompass a wide variety of benign and malignant tumors, since the eyelid has many tissue types. These tumors sometimes mimic common inflammatory conditions. Nonetheless, clinical investigation of these conditions remains limited. OBJECTIVE: To investigate the clinical and histopathological characteristics of eyelid skin tumors. METHODS: We retrospectively reviewed the medical records and clinical photographs of 148 patients with eyelid skin tumors confirmed by skin biopsy examination between January 2009 and May 2016. RESULTS: The mean patient age was 50.0 years, and the male-to-female ratio was 1:1.11. Malignant eyelid skin tumors accounted for 17.3% of the total number, and older patients were more likely to be affected by malignant tumors than benign tumors (66.2 years vs. 46.4 years). Epidermal cysts (15.5%), seborrheic keratosis (14.9%), and melanocytic nevus (14.2%) were the most common benign eyelid skin tumors. Basal cell carcinoma was the most common malignant tumor (69.2%), followed by squamous cell carcinoma (11.5%). Malignant skin tumors, especially basal cell carcinoma, predominantly involved the lower eyelid. No patient showed metastasis from the malignant skin tumors, and no case of recurrence was observed after wide excision of the tumors. CONCLUSION: Our findings suggest that various tumors, including malignant ones, can affect the eyelid area. This study provides useful data on the incidence and characteristics of eyelid skin tumors. Further investigation with a large group of patients is necessary to better understand the epidemiology of eyelid skin tumors.

BACKGROUND: The incidence of skin diseases in the university hospital may not truely indicate their province in the population, nevertheless it offers the only available source of information.Objective and Method: To study the prevalence of common dermatoses and compare this with previous reports, we reviewed 20, 000 new outpatients who visited the Department of Dermatology at Wonju Christian Hospital from 2000 to 2004, and have statistically analyzed the findings. RESULTS: The study results are summarized as follows: 1. Of the 20, 000 outpatients, the total number of male patients was 9, 871 (49.4%), and the numbers of female patients was 10, 129 (50.6%). 2. As for age distribution, the most frequent age group was the first decade (15.3%), fifth decade (15.1%), fourth decade (13.9%) and sixth decade (13.7%), comprising 58% of the total outpatients. 3. The 19 most common dermatoses were found to be dermatophytosis, atopic dermatitis, allergic contact dermatitis, other eczema, urticaria, alopecia, herpes zoster, seborrheic dermatitis, psoriasis, bacterial infection, pruritus, drug eruption, vitiligo, acne, verruca, irritant contact dermatitis, benign epidermal tumors, nevocellular nevus and hyperpigmentary disorders. 4. Those dermatoses which showed a decreasing tendency to be treated by medicine included allergic contact dermatitis, other eczema, bacterial infections, acne, and irritant contact dermatitis. An increasing tendency was noted in dermatophytosis, urticaria, alopecia, herpes zoster, seborrheic dermatitis, psoriasis, pruritus, drug eruption, vitiligo, verruca, benign epidermal tumors and nevocellular nevus. There was no significant annual difference in incidences of hyperpigmentory disorders compared to atopic dermatitis. 5. Diseases with high seasonal distribution in summer were dermatophytosis and verruca. However, atopic dermatitis, alopecia, herpes zoster and pruritus showed high incidence in the winter period. Acne showed a peak incidence in both summer and winter. 6. As for gender distribution, dermatophytosis, alopecia, seborrheic dermatitis, bacterial infection and vitiligo showed a high frequency in males, whereas allergic contact dermatitis, urticaria, herpes zoster, psoriasis, pruritus, drug eruption, acne, epidermal benign tumors, nevocellular nevus and hyperpigmentary disorders showed a high freguency in female. 7. In age distribution, atopic dermatitis, bacterial infection, vitiligo, verruca and nevocellular nevus were found to be the most frequent in the first decade, and acne and alopecia in the second decade. Urticaria and psoriasis were most frequent in the third decade; dermatophytoses, allergic contact dermatitis, irritant contact dermatitis and hyperpigmentary disorders in the fifth decade; other eczema, seborrheic dermatitis and pruritus in the sixth decade; herpes zoster and drug eruption in the seventh decade; and epidermal benign tumors in the eighth decade. 8. In the distribution of dermatoses as disease groups, eczema (25.5%), diseases of the skin appendages (10.8%), dermatophytosis (10.0%), erythema, urticaria and drug eruption(10.2%), viral infections (8.4%), papulosquamous disease (4.1%), and pruritus and neurocutaneous disease (3.9%) constituted 72.5% of the total. CONCLUSION: The distribution of skin disease in our hospital was similar to studies wnducted in other provinces. Comparing the alone results with earlier studies carried out in the same area by Lee (3), Won (2) and Song (1), there was a relatively low incidence of dermatoses caused by animal parasites. However, a predominently high incidence of age related dermatoses was found.
