Background and Objective : Bowen's disease is a type of an in situ squamous cell carcinoma. Typical type of Bowen's disease present as a gradually growing well-dermarcated erythematous plaque with an irregular border and surface crusting or scaling. This case demonstrates that Bowen's disease which had a relapse during applying the topical imiquimod can be treated by herbal medicine. Methods : A 72-year-old man patient presented with a erythematous plaque on his right medial malleolar area. The diagnosis of Bowen's disease was based on the clinical features. The chief complaints were scales, fissures, crusts and dryness of skin, erythema plaque, hyperpigmentation, bleeding, tenderness on the lesion. He was treated with Mahaengeuigam-Tang for 77 days. The severity of Bowen's disease was evaluated by visible assessment to determine the end-point of clearance. Results : After the treatment, fissures, crusts and dryness of skin and bleeding, tenderness on the lesion were vanished. Scales and erythema plaque, hyperpigmentation of the lesion little remained. Conclusions : Mahaengeuigam-Tang can be used on the treatment of skin disease which has characteristics plaques and crusts of skin.

Purpose: The objective of this study is to present a reliable method of scrotal reconstruction. Methods: 75 year - old - man visited the out patient department of urology for chronic itching sensation in his scrotal area, diagnosed as Bowen's disease. After the wide resection of scrotal lesion, reconstruction was carried with pedicled anterolateral thigh perforator flap. All operation procedure was done with an usual manner, previously reported. Donor site was closed primarily. Results: In 6th month follow - up period, there was no event, such as flap necrosis, wound dehiscence, tumor recurrence. And tactile sensation was recovered. Conclusion: In the Korean literature, there have not been the report that describes the reconstruction of scrotal defect using pedicled anterolateral thigh perforator flap. Pedicled anterolateral thigh perforator flap is reliable and robust flap for scrotal reconstruction.

Disseminated superficial actinic porokeratosis (DSAP) is a rare keratinization disorder. It is histopathologically characterized by the presence of coronoid lamellae and clinically by lesions showing central atrophy with elevated borders. Squamous cell carcinoma originating in the classical Mibelli subtype of porokeratosis is well-documented; however, few reports have described squamous cell carcinoma in DSAP lesions. We report the case of a 76-year-old woman with DSAP who developed Bowen's disease, actinic keratosis, and keratoacanthoma on her face.

Incidence of basal and squamous cell carcinoma is increasing among Korean. With increasing this incidence we need to attend the management and prevention of these cutaneous malignancies. Basal cell carcinoma (BCC) is the most common skin malignancy. Sun exposure is the most important environmental cause of BCC. Daily sun protection especially avoiding sun exposure between 10 a.m. and 4 p.m. provides most effective prevention against chronic ultraviolet-induced skin damage. Hedgehog pathway inhibitors are used locally advanced and metastatic BCC lesions in Korea. Until recently, there are no reports whether it developed resistance of Hedgehog pathway inhibitors with advanced BCC in Korean patients. Among malignant skin tumors, 19.1% were squamous cell carcinoma (SCC). The incidence of SCC was rapidly increased over the past years. However, the incidence rate of SCC in Japan has not been changed from the period 1976-1980 to 1986-1990. Sentinel lymph node biopsy for SCC did not provide diagnostic value. Bowen's disease and Erythroplasia of Queyrat are considered as carcinoma in situ of the skin. Erythroplasia of Queyrat have worse prognosis with a higher rate of malignant degeneration. Dermoscopy may helpful tool in assisting the noninvasive diagnosis of carcinoma in situ of the skin.

Background After skin tumor excision on the face, extremities, or trunk, the choice of treatment for a skin defect is highly variable. Many surgeons prefer to use a local flap rather than a skin graft or free flap for small- or moderately-sized circular defects. We have used unilateral or bilateral V-Y advancement flaps, especially on the face. Here we evaluated the functional and aesthetic results of this technique. Methods All of the patients were pathologically diagnosed with squamous cell carcinoma (SCC), basal cell carcinoma (BCC), or malignant melanoma or premalignant lesion (Bowen's disease). Thirty-two patients underwent V-Y advancement flap repair (11 unilateral and 21 bilateral) from January 2007 to June 2011. We analyzed the patients' age and satisfaction, and location and size of defect. The patients were followed up for 6 months or more. Results There were 22 women and 10 men. The ages ranged from 47 to 93 years with a mean age of 66 years. The causes were SCC in 15 cases, BCC in 13 cases, malignant melanoma in 1 case, Bowen's disease in 2 cases, and another cause in 1 case. The tumor locations were the face in 28 patients, and the scalp, upper limb, and flank each in one patient. All of the flaps survived and the aesthetic results were good. Postoperative recovery was usually rapid, and no complication or tumor recurrence was observed. Conclusions The V-Y advancement flap is often used not only for facial circular defects but also for defects of the trunk and extremities. Its advantages are less scarring and superior aesthetic results as compared with other local flap methods, because of less scarification of adjacent tissue and because it is an easy surgical technique.

Background: It is well known that skin cancer and precancerous disease develop more frequently in patients undergoing solid organ transplantation than normal populations in the normal population in Western countries. However, to date, the clinical and demographic features of skin cancer and precancerous disease after solid organ transplantation are not established in Asian countries. We evaluated the clinical and demographic features of primary skin cancer and precancerous lesions after solid organ transplantation and compared these with the trends observed in Western countries. Methods: We retrospectively reviewed the medical records of patients who underwent kidney, liver, heart, and lung transplantation between January 1995 and April 2017 and who developed skin cancer or precancerous lesions after transplantation. The various lesions observed were squamous and basal cell carcinoma, malignant melanoma, Kaposi sarcoma, Bowen's disease, and actinic keratosis. Results: We identified 4604 patients who received organ transplant. The mean age of patients was 44.8 years (male, 64.6%; female, 35.4%), and the sum of the person-year of observation time was 31,024 person-years. The incidence rate per 100,000 person-years was 29.01 for squamous cell carcinoma, 19.34 for basal cell carcinoma, 6.45 for malignant melanoma 3.22 for Kaposi sarcoma, and 74.17 for Bowen's disease and actinic keratosis. The incidence rate per 100,000 person-years was the highest in patients undergoing heart transplantation (610.50), followed by those who underwent kidney transplantation (136.54) and liver transplantation (90.15). Koreans showed lower incidence rates than those observed in Westerners. Conclusion: The incidence of primary skin cancer and precancerous lesions after solid organ transplantation in Koreans was lower than that in Westerners. Squamous cell carcinoma was the most common skin cancer in patients undergoing solid organ transplantation and the incidence rate of skin cancer and precancerous lesions was the highest in patients undergoing heart transplantation.

Sunlight causes various types of adverse skin changes on the sun-exposed areas of the skin, in which the most hazardous one is the induction of malignant skin tumours. FT -IR spectra were obtained from specimens excised from normal skin, BCCs, SCCs, MMs, nevi, lesions of solar keratosis and Bowen's disease. Tissue samples from freshly frozen specimens were cut into 2 sections in strictly sequential order to be stained with H & E for histopathological analysis, and then to be air-dried on CaF$_2$ slide glasses for further spectral data acquisition from defined area of interest. Intra- and inter-sample variations were estimated within grouped lesion categories according to each skin component. Mean spectra for each type of tissue pathology in the 800-1800 $cm^{-1}$ / region was interpreted using the classical group frequency approach that showed the most visible differences in spectra of benign, premalignant and malignant changes directly related to protein conformation and nucleic acid bases. The relative intensity of the nucleic acid peak was increased with progression to malignancy. In addition, PCA was able to evaluate and maximise the differences in the spectra by reducing the number of variables characterizing each patient and pathology category. This type of approach to non-destructively estimate the complexity of IR-spectra of inhomogeneous samples such as skin demonstrates the advantage of FT -IR microspectroscopy to be able to observe diseased states (benign, premalignant, malignant) and distinguish them from normal against a huge background of inter- and intra-subject variability.

Introduction: The aim of the study was to explore the distribution of eyelid tumors in Ankara, the capital city of Turkey, from a histopathological point of view. Materials and Methods: Medical records of 1,502 patients who had eyelid surgery because of tumoral lesions were retrospectively reviewed after obtaining institutional review board approval. A total of 1,541 lesions with histopathologic diagnosis were included. Inflammatory tumoral lesions were excluded. The lesions were categorized into three groups according to the origin: epidermal, adnexal tumors and 'others', including melanocytic, neural and vascular lesions. Results: Of the total of 1,541, 908 lesions were epidermal in origin. Only 22 (1.5%) were malignant, and 6.0% was premalignant lesions such as actinic keratosis and Bowen's disease. Twenty-one of 22 malignant lesions were basal cell carcinoma. There was only one patient with squamous cell carcinoma and no sebaceous cell carcinoma. Among the benign tumors (92.5%), squamous papilloma was the most frequent (21.8% of all lesions). The other frequent lesions were nevus (17.6%), seborrheic keratosis (17.3%), hydrocystomas (10.6%), xanthelasma (7.6%) and epidermal cysts (7.2%). Conclusions: The results of this study are in accordance with published literature. The absence of sebaceous cell carcinomas needs to be stressed.

암조직에 대한 면역반응은 종양의 성장을 억제하거나 유도한다. Foxp3 양성 T 림프구는 종양에 대한 면역억제 반응을 유도하여 종양의 성장을 유도하는 반면 CD8 양성 T 림프구는 종양의 성장을 억제한다. 본 연구에서는 피부에서 발생한 편평세포암종, 편평세포 암종의 전암병변인 광선각화증과 보웬병 그리고 기저세포암종 조직에 면역조직화학염색을 시행하여 CD8 양성 T 림프구 및 Foxp3 양성 T 림프구의 분포 그리고 두 종류의 림프구의 비(CD8/Foxp3)를 조사하여 다음과 같은 결과를 얻었다. CD8 양성 T 림프구와 Foxp3 양성 T 림프구는 보웬병과 평평세포암종의 침습부위에서 광선각화증과 기저세포암종의 침습부위에 비하여 더 많이 침윤하였으며 CD8/Foxp3는 보웬병에서 광선각화증과 기저세포암종의 침습부위에 비하여 낮았다. CD8 양성 T 림프구와 Foxp3 양성 T 림프구의 침윤 정도 및 CD8/Foxp3는 보웬병과 편평세포암종의 침습부위에서 유의한 차이가 없었다. 기저세포암종과 편평세포암종에서 CD8 양성 T 림프구와 Foxp3 양성 T 림프구는 침습부위에서 종양의 중심부위에 비하여 더 많이 침윤하였다. 이러한 결과로 보아 편평세포종양과 기저세포암종은 서로 다른 면역반응을 보이며 종양내에서도 부위에 따라 상이한 면역반응을 보인다고 생각된다.
