ABSTRACT
BACKGROUND: Impetigo is a common bacterial infection caused by Staphylococcus aureus, and group A beta-hemolytic Streptococcus or both. Recently, S. aureus has been reported as the most frequently isolated pathogen of impetigo and the incidence of methicillin-resistant S. aureus (MRSA) among patients with impetigo has increased. OBJECTIVE: To investigate the predominant microorganism and the antibiotic susceptibility of the impetigo causative pathogen. METHODS: Bacterial culture and antimicrobial susceptibility testing were performed in patients with impetigo from June 2006 to May 2012. RESULTS: Of 164 patients, bacteria were cultured from 139 patients. Among them, S. aureus was isolated from 114 (82%) patients. The others were Acinetobacter baumannii, Enterobactercloacae, Enterococcus species, Enterococcus faecium, Enterococcus faecalis, Klebsiella oxytoca, and Candida albicans. The resistance rates of S. aureus against antibiotics were as follows: penicillin, 95.6%; erythromycin, 43.9%; fusidicacid, 38.1%; clindamycin, 24.5%; gentamycin, 21%; tetracycline, 12.3%; trimethoprim-sulfamethoxazole, 0.9%; ciprofloxacin, 0%; habekacin, 0%; linezolid, 0%; teicoplanin, 0%; and vancomycin, 0%. Thirty-four (29.8%) S. aureus isolates were MRSA, and the prevalence of MRSA increased during the 6-year period. CONCLUSION: The most predominant pathogen in impetigo was S. aureus, which was sensitive to ciprofloxacin, habekacin, linezolid, trimethoprim-sulfamethoxazole, teicoplanin, and vancomycin. An increase in the prevalence of MRSA was observed during the 6-year period, and the effective antibiotics for MRSA were trimethoprim-sulfamethoxazole, teicoplanin and vancomycin.

A 29-year-old man presented with well-demarcated brown-to-erythematous patches with scales on the perioral and periocular areas. We could not find any other systemic signs and symptoms, except for the cutaneous findings and no abnormal results were found on laboratory tests. Histologic examination showed upper dermal granulomatous infiltrate and led us consider the diagnosis of granulomatous periorificial dermatitis. After daily taking oral minocycline 200 mg with application of topical tacrolimus ointment for 8 weeks, combined with the application of topical tacrolimus ointment, the lesion showed a marked improvement without scarring.

BACKGROUND: Bowen's disease is a challenging condition to treat because lesions often affect the elderly who are usually intolerable to invasive treatment modalities and lesions are often located at sites that heal poorly. OBJECTIVE: The aim of this study was to evaluate the effectiveness and the safety of 5% imiquimod cream for the treatment of Bowen's disease. METHODS: Eleven patients with biopsy-proven Bowen's disease were treated with once-daily or twice-daily self- application of 5% imiquimod cream for a maximum of 16 weeks. RESULTS: Nine of ten (90%) patients who completed the treatment schedule showed complete clinicopathologic regression. One (11%) patient showed recurrence of Bowen's disease on the treated site. 5% imiquimod cream was generally well-tolerated and no serious side effects were observed. CONCLUSION: 5% imiquimod cream appears to be an effective modality for treatment of Bowen's disease and might represent a valuable alternative to surgery or other invasive treatment methods.

Cutaneous horn is a clinical description for a protruding mass of keratin, which may arise from benign and malignant lesions. There have been 21 cases of cutaneous horns reported in Korea: 19 cases in adults, 2 cases in children, and no case in infants. We report the case of an 8-month-old girl who presented with a pea-sized, hyperkeratotic nodule on the dorsum of the right foot. Histopathologic examination confirmed the nodule to be a cutaneous horn arising from an angiokeratoma.

Semicircular lipoatrophy is a rare entity characterized by atrophic cutaneous indentation, typically involving the anterolateral thigh of young women. Although many previous reports have failed to reveal underlying trauma histories, repeated external microtraumas seem to be the most plausible causal factor at present. We report a case of semicircular lipoatrophy which occurred on both thighs of a 23-year-old woman after she started a new job as a waitress in fast-food restaurant.

Immunosuppressive therapy has been reported to exacerbate or initiate the development of porokeratosis. We report a patient who noted a dramatic worsening of previously unrecognized lesions of porokeratosis accompanied by malaise and fatigue. He was subsequently found to have myelodysplastic syndrome. On the basis of this case, the sudden appearance or exacerbation of disseminated porokeratosis without immunosuppressive therapy may justify the search for underlying immunodepressive conditions.
