We report the case of a 23-year-old woman who developed bowenoid papulosis of the vulva and subsequent periungual Bowen's disease. She had a history of a long standing periungual wart on her right thumb before the outbreak of periungual Bowen's disease. By HPV DNA chip, human papillomavirus (HPV) 11, 18 and 31 were identified from the periungual lesions, and HPV 11, 18 and 33 from the vulvar lesion. This case supports the theory of anogenital-digital spread of HPV, and proposes that the periungual wart may change into Bowen's disease by mucosal HPVs. To the best of our knowledge, this case is important as the first Korean case of periungual Bowen's disease concurrent with bowenoid papulosis of the vulva.

Mycobacterium chelonae is a rapidly growing atypical mycobacterium found in soil and water. In a healthy person, it causes cutaneous infection after an invasive procedure or surgery. Herein, we present a case of a 52-year-old man with multiple erythematous plaques and nodules on the back and left arm, and these occurred at the site of bee sting therapy by a herbal medical doctor. The histologic findings showed a granulomatous infiltration composed of numerous neutrophils, lymphocytes, eosinophils, histiocytes and multinucleated giant cells. Acid fast bacilli were detected by Ziehl-Neelsen stain and Mycobacterium chelonae infection was confirmed by an INNO-LiPA mycobacteria kit. The patient was treated with 1 g of clarithromycin and 200 mg of doxycycline for 6 months and his condition improved considerably.

Oral hairy leukoplakia (OHL) is caused by the reactivation of a previous Epstein-Barr virus (EBV) infection in the epithelium of the tongue. Most lesions are characterized by corrugated whitish patches on the lateral border of the tongue. It is frequently associated with AIDS, but cases in patients with other immunosuppressed states have also been reported. In leukemia patients, OHL is rarely encountered, and appears only after chemotherapy. We report a case of OHL which occurred as a presenting sign of acute myeloid leukemia (AML) in a previously healthy 15-year-old child. A 15-year-old boy presented with a whitish patch on the left lateral border of the tongue. The biopsy specimen revealed papillomatosis, hyperkeratosis, acanthosis and ballooning degeneration in the stratum spinosum. The patient was EBV seropositive, and PCR analysis of EBV DNA in the lesional tissue was positive. After the diagnosis of OHL in dermatologic department, the patient was referred to pediatrics due to the abnormal peripheral blood smear, and was diagnosed with AML.

BACKGROUND: Sarcoidosis is a chronic idiopathic disorder characterized by the formation of noncaseating granulomas. Multiple organs may be involved, including the skin, lung, lymphatic systems, liver, spleen and eyes. On average, 25% of sarcoidosis cases have cutaneous involvement. OBJECTIVE: The purpose of this study was to investigate the clinical characteristics of cutaneous sarcoidosis and the involvement of systemic organs according to clinical types of skin lesions. METHODS: A total of 32 patients diagnosed by histologic examination at Hospital from 2001 to 2009 with cutaneous sarcoidosis were enrolled in this study. The clinical features were obtained by reviewing medical records, clinical photographs and radiological images. RESULTS: The male to female ratio was 1 : 3 and 78.2% of patients were in their fifth to seventh decades. The most common cutaenous lesions were nodules (56.3%), especially the subcutaneous type (21.9%). The most frequently involved organ type was intrathoracic (71.9%), followed by the peripheral lymph nodes (25%), spleen (6.3%), and eyes (6.3%). Most patients with subcutaneous nodules, erythema nodosa, lupus pernio and discoid lupus-like plaques showed systemic involvement, whereas most patients with nodules or papules did not show systemic involvement. Of particular note, patients with subcutaneous nodules and lupus pernio showed more frequent involvement of the peripheral lymph nodes, spleen and intrathoracic region. CONCLUSION: In this study, patients with subcutaneous nodules and plaques showed more frequent systemic involvement, while most patients with nodules or papules showed no systemic involvement.

BACKGROUND: Hand eczema is a common skin disease in the general population. The etiology of hand eczema is obscure and many causative factors have been proposed. However, there are only a few reported studies of the relevance of contact allergy in hand eczema. Objective: The purpose of this study was to evaluate the diagnostic value of the patch test for patients with hand eczema. METHODS: We analyzed the clinical characteristics and the results of the patch tests of the 37 patients with hand eczema and we then compared these with the clinical subtypes. RESULTS: 26 patients (70.3%) showed a positive test to one or more allergens. The common allergens were nickel sulfate (35.1%), mercury ammonium chloride (21.6%), and cobalt chloride (18.9%). The positive rates for a patch test were 82.4% for the vesicular form, 77.8% for the fissured form, 20.0% for the hyperkeratotic form and 66.7% for pompholyx, respectively. We found more significant improvement of the clinical symptoms in the vesicular group (57.1%) than that in the non-vesicular group (9.3%) after avoiding the verified allergens. CONCLUSION: This study shows that the patch test is a useful tool for the detection of contact allergens and it must be performed for the patients with hand eczema, and especially for those patients with the vesicular type.

Granuloma annulare (GA) is a benign granulomatous disease. Although its etiology is not well understood, there are some reports about GA occurring after specific conditions such as sunburn, a tuberculin test, insect bites, viral diseases and trauma. Especially, in case of the auricular region which is vulnerable to trauma, it seems that GA has some relation with trauma. In 1992, Mills and Chetty proposed that repetitive minor trauma may be an important cause of auricular GA. Among the 5 cases of auricular GA that have been reported in the English literatures, 3 cases are assumed to be associated with repetitive minor trauma. Herein, we report on two cases of auricular GA that were thought to be associated with repetitive minor trauma.

Lipoma is the most common neoplasm of mesenchyme, and several subtypes have been described that vary according to their location and the presence of other tissue elements. Angiomyxolipoma is a very rare variant that consists of an admixture of adipose and myxoid elements with numerous vascular structures. It should be differentiated from other subtypes of benign and malignant lipomas. Here the case of a 69-year-old male is described who presented with a solitary asymptomatic mass on the left iliac crest. The histopathologic findings showed alternating nests of myxoid and adipose tissue containing dilated blood vessels, which was consistent with angiomyxolipoma.

Granulomatous mycosis fungoides is a rare type of cutaneous T-cell lymphoma. The patients with this illness do not present with distinct clinical findings, so the diagnosis depends on the demonstration of a malignant lymphoid infiltration in combination with a granulomatous tissue reaction. A 38-year-old woman presented with erythematous to purple-colored, focally atrophic, scaly plaques on the right inguinal area and diffuse erythematous scaly patches and multiple erythematous papules on the trunk. The histopathological findings showed non-necrotizing granulomatous infiltrates admixed with an atypical lymphocytic component and epidermotropism. Herein, we report a case of granulomatous mycosis fungoides.

OBJECTIVE: The purpose of this study was to determine any differences in outcome and patient satisfaction between endoscopic release (ECTR) and open carpal tunnel release (OCTR) in patients with bilateral carpal tunnel syndrome who underwent both techniques. METHODS: Seven patients with confirmed bilateral idiopathic carpal tunnel syndrome were randomized to undergo endoscopic release using a single portal Agee technique to one hand and a minimal open release to the other. Subsequent assessments were made at 0, 3, and 12 months after operation using a modified Levin scale. We also analyzed subjective and objective outcomes retrospectively, including the time to return to full activity, patient preference, cosmetic satisfaction, scar tenderness, and pillar pain. The pain was assessed using a visual analogue scale from 1 to 10. RESULTS: Based on the Levin scale, there were no significant differences between hands at any follow-up interval. At the three-month follow up, mean scale scores were lower in the ECTR group; however, the differences did not reach statistical significance. Cosmetically, all patients were satisfied with their scar irrespective of the technique. There were no statistical differences in terms of scar tenderness and pillar pain. CONCLUSION:ECTR did not show any significant advantage over short-incision OCTR. Therefore, the operator's experience and skill in using a certain method is important, regardless of which technique is used.
