We report herein a case of lymphomatoid papulosis showing atypical clinical manifestations. A 54- year-old man had had recurrent erythematous necrotic papules and nodues, numbering more than 200 lesions at the most aggravated time, on the trunk, extremities, buttok, and face for the last twenty years. Recently, he complained of tender swelling on the neck, axillae, and inguinal lymph nodes accompanied by mild fever and gerneral weakness. We had performed thorough examinations including biopsy from the skin lesions, lymph node, and bone marrow to detect some evidences of transforming to malignant lymphoma, but found no evidence of malignant lymphoma except aneuploidy on DNA histogram. The patients showed proinpt response to methotrexate 10-30mg par week wit,hout showing distinct side reactions to the accurvulated dose of 780mg for the last 16 months.

The purpose of this study was to investigate the antibacterial effect of the low temperature atmospheric plasma device with needle tip designed for easy approach to the oral cavity and root canal against Streptococcus mutans, Enterococcus faecalis and Candida albicans. The antibacterial activities evaluated by measuring clear zone of agar plate smeared with each bacteria after plasma treatment. To quantify antibacterial effects, dilution plate method was used. In addition, scanning electron microscope (SEM) was used for observation of changes in bacterial morphology. As treatment time of plasma increased, the clear zone was enlarged. The death rate was more than 99%. The SEM results showed that the globular shape of bacteria was distorted. These results suggest that needle tip plasma could be an innovative device for prevention of dental caries, and treatment of apical infection and soft tissue diseases.

Lower midface concavity due to depressed nasal base and pyriform aperture may be aesthetically displeasing. A relative deficiency in lower midface projection may be congenital or acquired, particularly after cleft surgery and trauma. People with normal occlusion associated with lower midface concavity due to depressed nasal base and pyriform aperture can be corrected with an autologous bone graft or artificial implants. The authors performed paranasal augmentation with an alloplastic implants using a porous polyethylene implants(Medpor(R)) on 430 patients who had visited authors' hospital for aesthetic correction of lower midface contour from January 2000 to June 2009. 425 patients were satisfied with the outcome, which gave them a natural contour. Complications such as dislocation, displacement, infection and extrusion were not observed. Only five patients had their implants removed due to displeasing and foreign body sensations. Alloplastic augmentation in the paranasal area is a very easy procedure and can simulate the visual effect as that of maxillary advancement osteotomy. Paranasal augmentation using a porous polyethylene implants(Medpor(R)) in patients having lower midface concavity with normal occlusion can contribute to the enhancement of the lower midface contour.

Granuloma annulare (GA) is a common non-infectious granulomatous disease. Generalized GA is the second most common variant of GA. It is often associated with recalcitrant disease progression despite treatment. The lesion of generalized GA typically presents widespread papules that coalesce to form annular plaques over the whole body.We report a case of a patient with disseminated papules and coalescing annular plaques, primarily involving the intertriginous area and mimicking tinea corporis or cruris. Histopathological findings confirmed the lesion as GA. This case underscored the unusual clinical presentation of generalized GA. A case of GA localized to the intertriginous area has rarely been reported. Given the recalcitrant nature of the disease, dermatologists should consider generalized GA as a differential diagnosis in patients with an annular lesion involving the intertriginous area. Thus, we report this as an atypical case of generalized GA localized to the intertriginous area.

Background: Cosmetic units are designated based on their similarity in topographic anatomy, texture and color, solar exposure, hair density, and sebaceous features. The difference of such features in facial port-wine stain (PWS) cases can affect the response to pulsed dye laser (PDL) treatment. Objective: To evaluate the response of facial PWS to PDL treatment based on the underlying cosmetic units. Methods: A retrospective study was conducted on 18 patients with facial PWS who received PDL treatment. For clinical assessment, three dermatologists evaluated the photographs taken before each treatment session. The response grade was assigned according to the quartile grading scale. The lesion was classified based on the underlying cosmetic units. Results: The cheek was the most (50%) commonly involved area. All PWS (6/6) confined to one cosmetic unit showed a marked improvement compared with 16% PWS (2/12) affecting two or more units (p＜0.05). Patients with PWS within one cosmetic unit required fewer treatment sessions to achieve marked improvement. Conclusion PWS confined to a single cosmetic unit than that located in two or more units responded better to PDL treatment. Before PDL treatment for facial PWS, age, initial lesion size, as well as the number of cosmetic units affected by the lesion should be considered.

Sebaceous hyperplasia (SH) is a benign proliferation of the sebaceous glands. Ultraviolet radiation is known to be the cofactor for the pathogenesis of SH. Frequently reported adverse events of 308-nm excimer laser are erythema, burning or pain, and itching sensation.However, the role of excimer laser as an aetiological factor of SH is rarely reported in the literature. A 59-year-old female presented with several elevated, umbilicated papules on the face. Papular eruption appeared abruptly after 11 weeks of treatment for vitiligo which includes 308-nm excimer laser therapy. The distribution of lesion was associated with the treated area. Total cumulative dose was 3,300 mJ/cm 2 over 16 sessions. Histopathologic findings showed enlarged sebaceous glands composed of numerous lobules around a centrally located, widened sebaceous duct. Chronic sun exposure clinically causes SH was proved in the previous animal studies. Thus, we introduce a rare case of eruptive SH in the patient treated with 308-nm excimer laser.

Extramammary Paget disease (EMPD) is a rare adenocarcinoma that usually occurs in areas of the body that are rich in apocrine sweat glands. Great depth of tumor invasion is a well-known risk factor for worse prognosis. Paget cells usually are limited to the epidermis, whereas invasive EMPD, which infiltrates the dermis, is relatively rare. It is even rarer for the tumor to spread beyond the dermis. Only 3.1% of patients with EMPD of the penis and scrotum have exhibited infiltration of the subcutaneous fat layer. We report a case of a 62-year-old male with EMPD that invaded the subcutaneous fat layer. He presented with a several-year history of a slowly expanding erythematous plaque with the hypopigmented area on the left penoscrotum. One month before presentation, the patient had undergone punch biopsy at another hospital and diagnosed with EMPD. He had no personal history of urogenital cancers. The patient was treated with Mohs micrographic surgery, and negative margins were achieved after four stages. The histopathologic findings revealed Paget cells scattered throughout the epidermis. At the hypopigmented area, Paget cells extended to the subcutaneous fat layer with lymphovascular invasion. There was no evidence of recurrence at seven months postoperatively. Herein, we describe a case of hypopigmented EMPD that infiltrated the subcutaneous layer, which rarely has been reported in Korea.
