Endometriosis is a condition in which endometrial glands and mucosa exist outside of the uterus. It affects approximately 15% of menstruating women and the most frequent site involved is the pelvic cavity. Extrapelvic endometriosis is uncommon. Cutaneous endometriosis is commonly associated with previous surgical scars, but in rare cases, it can occur spontaneously. We report a case of a 42-year-old Korean woman who presented with a skin-colored nodule on the left inguinal area. The patient had no history of previous surgery. Tenderness was the only symptom associated with the lesion and there was no cyclic pain or swelling aggravating during menstrual periods. Histopathology revealed endometrial stroma surrounding the glandular structures and hemosiderin-laden macrophages compatible with the diagnosis. This case demonstrates that primary inguinal endometriosis can present with different clinical features and calls for awareness of the possibility of inguinal endometriosis in patients with tender nodules of the inguinal area.

Angiosarcoma is a rare malignant vascular tumor of endothelial origin. It can involve any organ, including the skin, soft tissue, liver, bone, spleen, and orbit. Skin is the most frequent site of primary angiosarcoma, however, metastatic skin involvement of angiosarcoma is exceptional. Wolf`s isotopic response implies that the new disease appeared at the site of an already healed skin disease. Several types of cutaneous lesions have been described, occurring within cleared cutaneous herpes zoster, or herpes simplex lesions. These lesions include comedones, granulomatous diseases, tinea, furunculosis, wart, psoriasis, pseudolymphoma, leukemia, lymphoma, basal cell carcinoma, squamous cell carcinoma and cutaneous metastases, from internal carcinoma. Herein, we report a case of cutaneous angiosarcoma of unknown origin that has developed at the site of a scar, after herpes zoster in a 79-year-old man as isotopic response.

Background: Physiological parameters of the skin measured by non-invasive methods have been considerably developed. It is known that there are some differences in physiologic parameters between different races. Objective: The purpose of this study is to understand the differences between the races. Methods: A total of 757 Mongolian participated in this study. All subjects had no major history of skin diseases requiring medical treatment. Several instruments were used such as Sebumeter, Corneometer, Mexameter for measuring sebum excretion rate, values of capacitance, melanin index and erythema index respectively. These were measured on various areas of the skin such as cheek, forehead, palm, outer arm, inner arm, back and buttock. Results: The sebum excretion rates showed higher in males than in females on the cheek and forehead in Mongolian. However, they showed higher in the females on the palm. There were good correlation between the skin sebum level and the capacitance in males and females. The melanin index and erythema index showed higher in males than in females at all sites. When we compared this with the data published in other countries, many data were similar to Korean rather than a western country`s. However, the capacitance data were lower than those of Korean. Conclusion: Although, this study has some limit for direct comparison between each race, our results can be used as basic data for the comparison between Mongolian and other races in the future.

Porokeratosis of Mibelli, a chronic heritable disorder of the skin, presents with characteristic histopathological features including cornoid lamella as a result of faulty keratinization. Amyloid deposits are characterized by the accumulation of ultrastructually fibrillar material and have been observed in inflammatory and tumoral skin diseases. Some cases of amyloid deposits in the upper dermis in various subtypes of porokeratosis have been reported, but no porokeratosis of Mibelli reports are available in Korea. We report a case of a 26-year-old woman with three verrucous hyperkeratotic plaque lesions on her right popliteal fossa with histological feature of hyperkeratosis, cornoid lamella, and dermal amyloid deposits.

Background: Telemedicine is broadly defined as using telecommunication technology to transfer medical information. Teledermatology is defined as using telemedicine in the field of dermatology, and this can be divided into a storage-and-forward system and a live interactive system. The latter uses video-conferencing equipment and it is known to be more useful than the former. However, there have been few studies on live interactive teledermatologic consultation in Korea. Objective: We wanted to describe and quantify teledematologic consultation and to assess patients` satisfaction with the live interactive consultation by using a questionnaire. Methods: We retrospectively reviewed the records of the patients who were consulted through the teledermatologic system. To assess patients` satisfaction with the live interactive teledermatologic consultation, we asked the patients to complete a questionnaire after the consultation. Results: A total of 98 patients were consulted for 112 skin problems. The most frequent skin problem was eczematous diseases (33.9%), followed by infectious diseases (25.0%). Concerning the treatment efficacy, 90.7% of the patients experienced improvement of their initial symptom. Only one main diagnosis was recorded for 64.3% of the cases, and one main diagnosis with one other possible diagnosis to be differentiated was recorded for 30.4% of the cases. For the aspect of the technical quality, 66.1% of the patients were satisfied or very satisfied with the erformance of the instruments for live interactive communication. In addition, half of the patients were satisfied or very satisfied with the teledermatologic consultation, and 59.7% of the patients answered that they would use teledermatologic consultation system again if another skin problem develops. Conclusion: With its good performance, teledermatologic consultation seems to be helpful and satisfactory for the patients who are unable to visit the dermatologic out-patients clinic.
