OBJECTIVES: Verrucous epidermal nevus (VEN), seborrheic keratosis (SK), verruca plana (VP), verruca vulgaris (VV), and nevus sebaceous (NS) are common verrucous proliferative skin diseases with similar clinical appearances, often posing diagnostic challenges. Dermoscopy and reflectance confocal microscopy (RCM) can aid in their differentiation, yet their specific features under these tools have not been systematically described. This study aims to summarize and analyze the dermoscopic and RCM features of VEN, SK, VP, VV, and NS. METHODS: A total of 121 patients with histopathologically confirmed verrucous proliferative skin diseases were enrolled. Dermoscopy and RCM imaging was used to observe and analyze the microscopic features of these conditions. RESULTS: Under dermoscopy, the 5 diseases displayed distinct characteristics: VEN typically showed gyriform structures; SK was characterized by gyriform structures, comedo-like openings, and milia-like cysts; VP and VV featured dotted vessels and frogspawn-like structures; NS presented as brownish-yellow globules. RCM revealed shared features such as hyperkeratosis and acanthosis across all 5 diseases. Specific features included gyriform structures and elongated rete ridges in VEN; pseudocysts and gyriform structures in SK; evenly distributed ring-like structures in VP; vacuolated cells and papillomatous proliferation in VV; and frogspawn-like structures in NS. CONCLUSIONS These 5 verrucous proliferative skin conditions exhibit distinguishable features under both dermoscopy and RCM. The combination of these 2 noninvasive imaging modalities holds significant clinical value for the differential diagnosis of verrucous proliferative skin diseases.

OBJECTIVE: To compare the clinical therapeutic effect of fire needling stripping after local anesthesia, simple fire needling and liquid nitrogen cryotherapy on verruca vulgaris. METHODS: A total of 900 patients with verruca vulgaris were randomized into a fire needling stripping group (300 cases, 2 cases dropped off), a fire needling group (300 cases, 4 cases dropped off) and a liquid nitrogen cryotherapy group (300 cases, 5 cases dropped off). After local anesthesia of compound lidocaine cream, fire needling therapy was adopted, and the necrotic tissue of verruca was stripped in the fire needling stripping group. Simple fire needling therapy was adopted in the fire needling group, without local anesthesia and stripping. Liquid nitrogen cryotherapy was adopted in the liquid nitrogen cryotherapy group. The treatment was given once a week, and totally 3 weeks were required in the 3 groups. The skin lesion scores of number, area, thickness, color, pruritus, isomorphism and the level of T lymphocyte (CD RESULTS: Compared before treatment, the skin lesion scores were decreased ( CONCLUSION Fire needling stripping after local anesthesia can effectively treat the verruca vulgaris, improve the skin lesion and immunity, its therapeutic effect is superior to simple fire needling and liquid nitrogen cryotherapy.

BACKGROUND: Warts, caused by the human papilloma virus (HPV), are mucocutaneous proliferations controlled by cell-mediated immunity. Intralesional immunotherapy with measles, mumps, and rubella (MMR) vaccine, is postulated to induce a higher immune response for clearance of lesions.
OBJECTIVE: To assess the efficacy, safety and effect on recurrence of intralesional MMR vaccine for the treatment of warts.
METHODS: We searched online databases for randomized controlled trials on intralesional MMR vaccine for warts. Effects measured were the complete clearance of target and distant warts, adverse events noted and recurrence after treatment duration.
RESULTS: Four RCTs comparing intralesional MMR vaccine and placebo were assessed. Meta-analysis showed a risk ratio of 0.24 [95% CI: 0.18, 0.34] favoring intralesional MMR vaccine and a highly significant difference in completely clearing target warts (P-value <0.00001) versus placebo. Three of the 4 trials assessed response of distant warts showing a risk ratio of 0.28 [95% CI: 0.08, 0.96] and a significant difference (P=0.04) versus placebo. Pain and flu-like symptoms were the most common side effects with no recurrence seen after 3-6 months.
CONCLUSIONS: Intralesional MMR vaccine significantly reduces and clears target and distant warts as compared to placebo. It is a generally safe intervention with lasting effect assessed up to 6 months follow-up.

Introduction: Intralesional purified protein derivative (PPD) is an affordable therapeutic option that has been studied for cutaneous warts. However, the lack of good evidence precludes its widespread use. Objective: To determine the efficacy and safety of intralesional PPD in the treatment of cutaneous warts. Methods: A systematic search for controlled clinical trials comparing intralesional PPD and placebo or any conventional therapy was conducted using electronic databases. The included studies were assessed for risk of bias, and data such as clearance rate of target and distant lesions, recurrence rate, and adverse events were extracted. Analysis was done through RevMan v5.3. Results: Four controlled clinical trials composed of 205 patients were included. All of the studies compared intralesional PPD to placebo as comparator. Intralesional PPD had a significantly higher clearance rate of target wart (RR=0.43[0.22,0.84], P=0.01) and a significantly higher clearance rate of distant lesions (RR=0.59[0.41,0.85], P=0.005) as compared to placebo. However, there was no significant difference in the recurrence rate (RR=0 [-0.07,0.07], P=0.98). Adverse events reported were only considered minor. Conclusion Intralesional PPD is an effective and safe treatment option for cutaneous warts. However, more well-structured RCTs with longer follow-up period and those comparing it with conventional treatment are needed to further support its use.

BACKGROUND: In Korea, new human immunodeficiency virus (HIV) patients continue to be diagnosed. Due to the development of highly active anti-retroviral therapy (HAART) and lengthening of survival period of infected person, the aspect of skin diseases of HIV-infected patients is also changing. OBJECTIVE: To determine skin diseases of HIV-infected patients according to immune status and the relationship between folliculitis and HAART drug. METHODS: Subjects were HIV-infected patients who were treated in the department of dermatology from September 1, 2008 to August 31, 2018. Medical records of 376 subjects were retrospectively analyzed. RESULTS: Of 376 patients were studied, tinea infection, folliculitis, and seborrheic dermatitis were the most common regardless of their CD4 T cell counts or treatment group (initial treatment or retreatment). Seborrheic dermatitis, irritant contact dermatitis, and pruritic papular eruption were significantly more common in patients with CD4+T cells less than 200×106 cells/L while warts were significantly more frequent in patients with CD4+T cells greater than 200×106 cells/L. Most HAART agents were found to be helpful in reducing the incidence of folliculitis. CONCLUSION: There were many skin diseases in HIV patients, different from previous studies. In our study, the top three diagnoses were tinea infection, folliculitis, and seborrheic dermatitis. HAART medication was helpful in reducing folliculitis. These changes will require different treatments for skin diseases in HIV patients.

PURPOSE: The aim of this study was to evaluate the diagnostic performance of a computer-aided detection (CAD) system used with automated breast ultrasonography (ABUS) for suspicious lesions detected on breast MRI, and CAD-false lesions. MATERIALS AND METHODS: We included a total of 40 patients diagnosed with breast cancer who underwent ABUS (ACUSON S2000) to evaluate multiple suspicious lesions found on MRI. We used CAD (QVCAD™) in all the ABUS examinations. We evaluated the diagnostic accuracy of CAD and analyzed the characteristics of CAD-detected lesions and the factors underlying false-positive and false-negative cases. We also analyzed false-positive lesions with CAD on ABUS. RESULTS: Of a total of 122 suspicious lesions detected on MRI in 40 patients, we excluded 51 daughter nodules near the main breast cancer within the same quadrant and included 71 lesions. We also analyzed 23 false-positive lesions using CAD with ABUS. The sensitivity, specificity, positive predictive value, and negative predictive value of CAD (for 94 lesions) with ABUS were 75.5%, 44.4%, 59.7%, and 62.5%, respectively. CAD facilitated the detection of 81.4% (35/43) of the invasive ductal cancer and 84.9% (28/33) of the invasive ductal cancer that showed a mass (excluding non-mass). CAD also revealed 90.3% (28/31) of the invasive ductal cancers measuring larger than 1 cm (excluding non-mass and those less than 1 cm). The mean sizes of the true-positive versus false-negative mass lesions were 2.08 ± 0.85 cm versus 1.6 ± 1.28 cm (P < 0.05). False-positive lesions included sclerosing adenosis and usual ductal hyperplasia. In a total of 23 false cases of CAD, the most common (18/23) cause was marginal or subareolar shadowing, followed by three simple cysts, a hematoma, and a skin wart. CONCLUSION: CAD with ABUS showed promising sensitivity for the detection of invasive ductal cancer showing masses larger than 1 cm on MRI.
