We report a case of a tick bite by Ixodes nipponensis found on the neck of a 75-year-old female. The tick was thought to be in the lesion for 10 days. Till now 31 cases of tick bites were reported in Korea including the present case. The review of the Korean cases revealed that the ratio of female/male was 1.3: 1, its age distribution was from 1st to 8th decade, sites of the invasion were trunk, head and neck, extremities, and anogenital area in order of frequency. Its prevalent season was spring and summer and the most common species(17/31) was Ixodes nipponensis. (Korean J Dermatol 2001;39(8): 891-895)

Background : It has been known that androgenetic alopecia in both male and female is due to the role of the androgen hormone in the hair follicle, but the level of the androgen hormone in the plasma is controversial in relation with the development of the alopecia. Objective : We have tried the clarify if there is any or no difference in the plasma levels of the hormones between the normal female and the patient with alopecia, because the range of the plasma DHEA-S and total testosterone in the normal female is very wide. Methods : Plasma levels if the hormones were examined in 22 patients with female androgenetic alopecia and 20 normal females. Results : 1. In DHEA-S, 21(95.5%) aut of 22 female androgenetic alopecia patients were in the normal range while 20(100%) of the 20 normal females were all within the normal range. However the mean value of the hormone(88.89+101.41 g/dl) in the patient group was significantly higher than that(82.18+44.03 g/dl) of the normal group(p<0.05). 2. In total testosterone, 17(94.4%) out of the 18 patents were in the normal range while 20 (100%) of 20 normal females were all within the normal range. However the mean value of the hormone(0.22+0.20ng/ml) in the patient group was significantly higher than that(0.08+0.09ng/ml) of the normal group(p<0.05). 3. As for distribution of DIEA S according to the age, the value of the patient group was higher than that of the normal group in all age groups studied. In the distribution of total testosterone according to age, there was no difference between the normal and the patient in the twenties. After the twenties, the testosterone levels were higher in the patients than the normal females. Conclusion : There were significant differences in mean values of plasma DHEA-S and total testosterone between the patients and the normal females although individuals in both groups were largely wit,hin normal range of the hormones.

A 19 year old female patient presented with diffuse alopecia as her chief medical complaint. A clinical examination revealed hirsutism limited only to the on midline lower abdomen with e~levated DHEA-S(dehydroepiandrosterone sulfate) and total testosterone levels. Polycystic ovarian disease (PCOD) was diagnosed during the treatment with dexamethasone and spironolactone, which was effective to improve her alopecia. We believe that, with increasiny, concerns about hair conditions of teen-age girls there should be increasing chances for dermatologists to care for patients of PCOD first before other specialities in medicine (Kor J Dermatol 1996;34(6): 1021-1025)

Background: Dermatitis occurring after ingestion of the urushiol chicken is quite common in Korea. Although many cases of the systemic contact dermatitis due to urushiol chicken have already been reported, systemic study on its epidemiology is not done yet. Objective .To elucidate the demography of the eaters of the urushiol chicken with its general understandings in society and the incidence of the resultant systemic dermatitis. Methods: By the help of the patients who developed the dermatitis, all the persons who ate it together with the patients were interviewed. Results & Conclusion : l. 171 eaters of the urushiol chicken(125 male and 46 female) were enrolled in this study(M:F= 3.1:1). The age group in 4th decade was the most common in male, the 5th decade in female. The age prevalence of the systemic contact dermatitis corresponded to the age prevalence of the eater. 2. Incidence rate of systemic contact dermatitis among the eaters was 32.2% (55/171). Incidence rate according to each age group were as follows : 0% in 2nd decade, 33.3% in the 3rd decade, 32.4% in 4th decade, 32.8% in 5th decade, 33.3% in 6th decade, 25% in the 7th decade. 3. One third (57/171) of the eaters ate the urushiol chicken to strengthen their internal organs, especially stomach, which they believed to be weak 70 persons (40.9%) ate it at home, 101 persons (59.1%) ate it at a restaurant. 4. Out of 67 persons having past history of allergic contact dermatitis to Rhus tree, 28 persons (41.8%) showed systemic contact dermatitis. Out of 104 persons without past history of allergy to Rhus, 27 persons (26.0%) showed systemic contact dermatitis. (Korean J Dermatol 2002;40(3): 253-257)

We report a case of pancreatic panniculitis associated with acute pancreatitis. The patient was a 63-year-old woman who presented with multiple painful erythematous nodules on both shins and had a mild fever and chill. Histopathologic findings showed fat necrosis with anucleate “ghost-like” fat cells with a thick shadowy wall. Laboratory evaluation revealed an increase in serum blood amylase and lipase. We diagnosed as pancreatic panniculitis associated with acute pancreatitis. Past medical history included rheumatoid arthritis and chronic renal failure treated with hemodialysis. She was taking several medicines due to rheumatoid arthritis and was newly prescribed the mizoribine (Bredinin(R)), 50 mg twice daily for 50 days. We therefore considered the possibility of drug induced pancreatitis due to mizoribine. (Korean J Dermatol 2008;46(5):674∼677)

Neuromas are hyperplasia of axons and associated nerve sheath cells. Cutaneous neuromas are uncommon. Three kinds of true neuromas exist in the skin and mucous membranes: traumatic neuromas, solitary palisaded encapsulated neuromas, and multiple mucosal neuromas. Traumatic neuromas are usually solitary, skin-colored or pink, firm papules or nodules at the sites of scars following local trauma. A 2-year-old male patient presented a solitary rice grain sized, skin-colored painful and tender polypoid papule on the left 2nd finger. The lesion was superimposed on a small linear scar. The patient had taken a trauma by a broken piece of glass about one month before the development of the neuroma. We report a case of traumatic neuroma with a review of the literature.

Sebaceous trichofolliculoma is a rare benign tumor and represents a variant of trichofolliculoma. It presents as a centrally depressed solitary tumor and occurs in areas rich in sebaceous lobules. Microscopically, it shows keratin-filled cystic cavities and sebaceous lobules. The lobules are connected to the cystic wall. Herein we report a case of sebaceous trichofolliculoma on the right cheek in a 64-year-old man. (Korean J Dermatol 2009;47(7):835~837)

Background: Burow`s graft is a useful full-thickness skin graft that employs the adjacent lax skin as a donor site and this is especially suitable for the facial region. When reconstructing a facial cutaneous surgical defect, we have to consider the facial cosmetic unit together with various other factors. Objective: The aim of this study was to assess the feasibility of using a Burow`s graft by dermatologists and the cosmetic outcomes of Burow`s graft for reconstructing facial defects, based on different facial cosmetic units. Methods: From August 2005 to February 2007, 26 patients were treated with the Burow`s graft technique for the reconstruction of facial cutaneous defects following Mohs micrographic surgery. According to the facial cosmetic unit, we divided the face into the forehead, periorbital area, nose, cheek and chin, and we redistributed the cases by the cosmetic units. The post-operative result of each case was rated with using serial clinical photographs that were taken at 1, 6 and 12 months, and the patient`s charts were reviewed by two independent physicians. Results: The cosmetic results of facial reconstructions by using Burow`s graft were satisfactory, regardless of the cosmetic unit. 21 cases out of the 26 cases (81%) showed good to excellent results after 6 months. The early cosmetic consequence of the periorbital region was better than those of the other facial cosmetic units. No side effects were reported other than a trapdoor deformity in three cases. Conclusion: Burow`s graft can be a good choice for reconstruction of facial cutaneous defects after skin cancer surgery in all the facial cosmetic units. (Korean J Dermatol 2008;46(10):1328∼1336)
