Atypical Fibroxanthoma.

Atypical fibroxanthoma (AFX) is a dermal spindle-cell sarcoma that is considered a superficial and clinically benign presentation of pleomorphic dermal sarcoma, malignant fibrous histiocytoma, and undifferentiated pleomorphic sarcoma. AFX appears clinically as a discrete red or pink nodule or papule, most commonly on the head and neck region of sun-damaged elderly patients. Histologic findings on routine hematoxylin and eosin staining reveal spindle-shaped, large, and pleomorphic tumor cells throughout the dermis. Immunohistochemistry is not specific for AFX, and the diagnosis is generally one of exclusion. AFX is best treated by complete surgical excision, with Mohs micrographic surgery considered the treatment of choice. Metastasis rarely occurs, but there is a high rate of local recurrence, especially in patients who are immunosuppressed.

A Clinical Review of Common Medications Used in Emergency Dermatological Situations.

BACKGROUND: Medical emergencies can occur in any environment, including dermatologic and procedural surgical settings. There are many options available to dermatologic surgeons, which they should consider having easily accessible in the office in case an emergency arises. OBJECTIVE: To summarize the current understanding about major medications that should be on-hand during dermatological surgeries. To review their mechanism of action, examine their general use, and dermatological use during surgical emergencies. METHODS AND MATERIALS: A comprehensive review using PubMed was performed, searching for studies using these various medications in relation to cutaneous surgeries. RESULTS: Distinct items such as hyaluronidase, nitroglycerin paste, aspirin, injectable epinephrine, and defibrillators are potential options to address various emergencies and should be readily accessible to dermatologic surgeons. CONCLUSION: Dermatologic surgeons' knowledge of key medications and options to have in the office allow for a proper response in the event an emergency arises.

The efficacy and use of finasteride in women: a systematic review.

BACKGROUND: Physicians are beginning to use finasteride as treatment for hair loss, hirsutism, and various other dermatologic conditions in women. However, the reported efficacy and use of finasteride in the female population varies widely. The purpose of this study is therefore to better define the efficacy and use of finasteride in women and identify research gaps that require further investigation. METHODS: A systematic review of the current literature describing finasteride use in women. RESULTS: A total of 2,683 patients participated in 65 studies involving finasteride use in women published between January 1997 and July 2017. Most randomized controlled trials (RCTs) evaluated finasteride use in women with hirsutism (48.7%) or female pattern hair loss (34.7%). RCTs recommend finasteride treatment for women with hirsutism or polycystic ovarian syndrome. Meanwhile, other forms of hair loss were studied such as alopecia, lichen planopilaris, and frontal fibrosing alopecia, but no RCTs evaluating finasteride therapy were identified. Other prospective and retrospective studies report that finasteride may improve hair loss in women with female pattern hair loss or frontal fibrosing alopecia. Overall, doses of oral finasteride ranged from 0.5 to 5 mg/day, in females aged 6-88, over a duration of 6-12 months (57.6%), as monotherapy (88.9%), and for continuous use (96.4%). CONCLUSION: The studies reviewed highlight the finasteride dosage, length of treatment, and candidate conditions that can benefit from finasteride therapy. Future long-term studies are necessary to fully assess the therapeutic mechanisms and potential consequences of finasteride use and to optimize treatment protocols.

Trichoscopic features of tinea capitis in a straight-haired Hispanic woman.

Comma and corkscrew hairs are trichoscopic markers of tinea capitis. Although comma hairs have been reported in both black and white patients with tinea capitis, corkscrew hairs were previously hypothesized to manifest exclusively in patients with curly or African hair types. However, we report a significant number of comma and corkscrew hairs in a Hispanic female patient with naturally straight hair and Trichophyton tonsurans tinea capitis. Thus, dermoscopy is a rapid, noninvasive, and cost-effective tool for evaluating tinea capitis and should be used in combination with culture in all patients regardless of hair texture or race.

Laser treatment of cutaneous angiokeratomas: A systematic review.

Angiokeratomas can present therapeutic challenges, especially in cases of extensive lesions, where traditional surgical methods carry high risks of scarring and hemorrhage. Argon, pulsed dye (PDL), neodymium-doped yttrium aluminum garnet (Nd:YAG), copper vapor, potassium titanyl phosphate, carbon dioxide, and erbium-doped yttrium aluminum garnet (Er:YAG) lasers have emerged as alternative options. To review the use and efficacy of lasers in treating angiokeratomas. A PubMed search identified randomized clinical trials, cohort studies, case series, and case reports involving laser treatment of cutaneous angiokeratomas. Twenty-five studies were included. Quality ratings were assigned using the Oxford Centre for Evidence-Based Medicine scheme. Several laser modalities are effective in treating multiple variants of angiokeratomas. Vascular lasers like PDL, Nd:YAG, and argon are the most studied and of these, PDL offers the safest side effect profile. Nd:YAG may be more effective for hyperkeratotic angiokeratomas. Combination treatment with multiple laser modalities has also demonstrated some success. Lasers are a promising treatment option for angiokeratomas, but current use is limited by the lack of treatment guidelines. There are limited high quality studies comparing laser treatments to each other and to non-laser options. Additional studies are needed to establish guidelines and to optimize laser parameters.

Melanoma arising in an ovarian cystic teratoma: a systematic review of presentation, treatment, and outcomes.

PURPOSE: To assess the clinical presentation, treatment modalities, and outcome of primary melanomas arising in ovarian cystic teratomas (OCT). METHODS: A systematic review on PubMed/MEDLINE was performed on June 5, 2017, to gather data on patients with primary melanomas arising in OCTs. No systematic reviews were identified. Consequently, only case reports and case series of individuals were analyzed. A total of 37 articles met our inclusion criteria, totaling 41 unique patients. RESULTS: The average age of diagnosis was 51.5 years. In total, 24% of patients were found to have metastatic disease. In total, 56.7% of patients eventually died of their disease, with an average time from diagnosis to death of 9.3 months. Disease recurrence was common, occurring in 65% of patients. The mainstay of treatment was surgical in 100% of the cases. Adjuvant chemotherapy, immunotherapy, and radiation were also used with varying degrees of efficacy. CONCLUSIONS: Malignant melanoma arising in OCT is a rare disease with poor prognosis. The current mainstay treatment is surgical. Potential benefits of targeted therapy, immunotherapy, and chemotherapy remain to be determined. A limitation of this study is that these melanomas have only been published in case reports.

Review of treatment for alopecia totalis and alopecia universalis.

Alopecia areata (AA) is an autoimmune disease directed at the hair follicle. Although usually limited to patchy hair loss over the scalp (focalis), AA can present as total loss of scalp hair (totalis; AT) or as total loss of both scalp and body hair (universalis; AU). Management of AT and AU can be challenging, and although multiple treatment modalities have been explored, no therapy is currently FDA-approved. This review focuses on the evidence for current treatment options for AT and AU. The PubMed database was searched from January 1, 2000, to September 1, 2016, for clinical trials, retrospective studies, and case reports of treatments for AT and AU. A total of 40 studies were retrieved and analyzed. Therapies studied for AT/AU included: topical immunotherapy, steroids, photodynamic therapy, immunosuppressive agents, TNFα inhibitors, and other therapies, such as sulfasalazine, bexarotene, JAK inhibitors, and simvastatin/ezetimibe. Although certain treatments showed significant hair regrowth, no treatment was completely effective. The most promising therapies with the highest quality data include diphenylcyclopropenone, squaric acid dibutylester, photodynamic therapy, steroids, and cyclosporine in combination with methylprednisolone. High-quality randomized-controlled trials with large sample sizes are lacking. Unified outcome guidelines are encouraged to facilitate the comparison of future studies.

Scrotal Melanoma: A Systematic Review of Presentation, Treatment, and Outcomes.

BACKGROUND: Primary male genital melanomas are rare. Of these, scrotal melanoma is the least common, and is unfortunately often detected late in the disease course. OBJECTIVE: To assess the clinical presentation, treatment modalities, and outcome of scrotal melanoma to aid clinician management. METHODS: Systematic literature review of PubMed, yielding 23 cases, of which 20 met the inclusion criteria. RESULTS: Although previously thought to have the best outcome of genitourinary melanomas, scrotal melanomas are associated with high mortality and late presentation. Scrotal melanoma presented as Stage I/II disease 18.75% of the time, Stage III 56.3% of the time, and Stage IV 25% of the time, whereas typical cutaneous melanoma presents as Stage I/II disease 84% of the time, Stage III 8% of the time, and Stage IV 4% of the time. Half of patients experienced recurrence of their disease. All patients who presented with metastases to distant organs died. LIMITATIONS: Small sample size. Few cases described a Breslow's depth making it difficult to draw conclusions on tumor thickness and survival outcome. CONCLUSION: Scrotal melanoma is rare, aggressive, and is often caught late in the disease course. The authors encourage dermatologists to educate patients and destigmatize genital lesions to increase the likelihood of earlier detection and better patient outcomes.

Splash Safety During Dermatologic Procedures Among US Dermatology Residents.

BACKGROUND: Dermatologists are at potential risk of acquiring infections from contamination of the mucous membranes by blood and body fluids. However, there are little data on splash safety during procedural dermatology. OBJECTIVE: To determine dermatology resident perceptions about splash risk during dermatologic procedures and to quantify the rate of protective equipment use. METHODS: An anonymous on-line survey was sent to 108 United States ACGME-approved dermatology residency programs assessing frequency of facial protection during dermatologic procedures, personal history of splash injury, and, if applicable, reasons for not always wearing facial protection. RESULTS: A total of 153 dermatology residents responded. Rates of facial protection varied by procedure, with the highest rates during surgery and the lowest during local anesthetic injection. Over 54% of respondents reported suffering facial splash while not wearing facial protection during a procedure. In contrast, 88.9% of respondents correctly answered that there is a small risk of acquiring infection from mucosal splash. Residency program recommendations for facial protection seem to vary by procedure. CONCLUSION: The authors' results demonstrate that although facial splash is a common injury, facial protection rates and protective recommendations vary significantly by procedure. These data support the recommendation for enhanced facial protection guidelines during procedural dermatology.

Challenges to smartphone applications for melanoma detection.

This commentary addresses the emerging market forhealth-related smartphone applications. Specific todermatology, there has been a significant increasenot only in applications that promote skin cancerawareness and education but also in those meantfor detection. With evidence showing that 365dermatology-related applications were available in2014--up from 230 in 2012--and that 1 in 5 patientsunder the age of 50 have used a smartphone tohelp diagnose a skin problem, there is clearly a largesubset of patients participating in this growing trend.Therefore, we are obligated to take a closer lookinto this phenomenon. Studies have shown thatapplications are inferior to in-person consultationswith one study showing that 3 out of 4 applicationsincorrectly classified 30% or more melanomas aslow-risk lesions. Although the FDA gained regulatoryoversight over mobile health applications in 2012and recently released their statement in 2015, theirreach only extends to cover a selected portion ofthese applications, leaving many unregulated asthey continue to be marketed toward our patients.Dermatologists should be updated on our currentsituation in order to properly counsel patients on therisks and benefits of these applications and whetherthey are acceptable for use.

Genital melanoma: are we adequately screening our patients?

Full-body skin exams (FBSE) play an integral role inearly detection and treatment of skin cancer. Promptdetection of melanoma is especially importantas survival outcomes decrease significantly withpresentation of advanced disease. Given thatmelanoma may grow in areas of skin with little to nosun exposure, genital melanomas are a recognizedentity in cutaneous oncology.

Quality of life outcomes associated with treatment of human immunodeficiency virus (HIV) facial lipoatrophy.

Facial lipoatrophy (FLA), characterized by a decrease in facial volume, has a high prevalence in patients with human immunodeficiency virus (HIV) infection treated with long-term highly active antiretroviral therapy (HAART). The social stigmatization that results from such changes in facial appearance has led some HIV patients to discontinue HAART. The use of fillers is one method of restoring facial volume. A critical outcome of treatment concerns the patient's quality of life (QoL). Although many studies have assessed patient satisfaction, as well as the social and psychological outcomes associated with the correction of HIV FLA, fewer studies have assessed QoL. We reviewed treatment options for HIV FLA with a specific focus on QoL outcomes. Our analysis revealed that the following treatments were associated with improvements in QoL: poly-l-lactic acid; calcium hydroxylapatite; hyaluronic acid; polyacrylamide gel; polyalkylamide gel; polymethylmethacrylate; silicone oil; and autologous fat transfer. The treatment of HIV FLA with these agents appears to improve QoL as assessed by various QoL instruments. Additional studies are required to identify a unifying QoL instrument to effectively assess longitudinal QoL outcomes and to compare treatment modalities.

Laser Treatment of Nongenital Verrucae: A Systematic Review.

IMPORTANCE: Although cutaneous warts are common lesions, full remission is not always achieved with conventional therapies. Laser modalities including carbon dioxide (CO2), erbium:yttrium-aluminum-garnet (Er:YAG), pulsed dye (PDL), and Nd:YAG have been investigated as alternative treatments for warts. OBJECTIVE: To review the use and efficacy of lasers for treating nongenital cutaneous warts. EVIDENCE REVIEW: Published randomized clinical trials (RCTs), cohort studies, case series, and case reports involving laser treatment of nongenital warts were retrieved by searching PubMed with no date limits. Quality ratings of studies were based on a modified version of the Oxford Centre for Evidence-Based Medicine scheme for rating individual studies. A higher emphasis was placed on RCTs and prospective cohort studies with large sample sizes and detailed methodology. FINDINGS: There were 35 studies published between 1989 and 2015 that comprised an aggregate of 2149 patients. Simple and recalcitrant nongenital warts treated with lasers show variable response rates (CO2 laser, 50%-100%; Er:YAG laser, 72%-100%; PDL, 47%-100%; and Nd:YAG laser, 46%-100%). Current RCTs suggest that PDL is equivalent to conventional therapies such as cryotherapy and cantharidin. Combination therapies with lasers and other agents including bleomycin, salicylic acid, and light-emitting diode have shown some success. CONCLUSIONS AND RELEVANCE: Lasers can be an effective treatment option for both simple and recalcitrant warts. The lasers most studied for this purpose are CO2, PDL, and Nd:YAG, and of these, PDL has the fewest adverse effects. Currently, use of lasers for wart treatment is limited by lack of established treatment guidelines. Future studies are needed to compare laser modalities with each other and with nonlaser treatment options, and to establish optimal treatment protocols.

Dermatologic health literacy in underserved communities: a case report of south Los Angeles middle schools.

BACKGROUND: The incidence of melanoma and other skin cancers has risen drastically in the United States.  As with most types of cancer, the prognosis and survival rates are significantly improved with early diagnosis, but dismal for patients who present with advanced disease.  It remains a fact that although melanoma is most common in Caucasian populations, ethnic minorities have a worse prognosis. Our hypothesis in this dermatologic health literacy study was that before necessary education, the required fund of knowledge with respect to skin cancer risk is lacking in several ethnic communities, but that intended compliance occurs when educational intervention occurs. METHODS: Three middle schools in South Los Angeles with predominantly Latino and African American youth were surveyed. Permission was obtained from the principals of the middle schools for the multi-day educational initiative. A total of 150 students were ultimately recruited and a pre-intervention survey administered. After preliminary review of the pre-intervention dermatologic health literacy results, a set of "core" learning concepts about sun safety were summarized and solidified for incorporation into the adolescent-appropriate sun safety protection pamphlet that was designed by designers at UCLA/Johnson & Johnson Health Care Institute. A full day of education on skin disease and the importance of sun protection from an early age was executed, followed three months later by a post-intervention visit that assessed compliance with the sun protection products and intended future use. RESULTS:   Results from the pre- and post-intervention surveys/questionnaires were analyzed and interpreted. Of 150 pre-intervention surveys that were distributed, 54 identified as African American and 96 of whom identified as Latino. Of these, 75% of Latino students reported having a sunburn in the last year, whereas only 38.9% of African American students reported a sunburn.  A total of 80% of the students reported as least some use of sunscreen in the 3 months prior to the post-intervention survey.  Only 8% of African American students reported "everyday" use, whereas 24% of Latino students reported "everyday" use (P < 0.05).  A total of 94% of the students intend to wear sunscreen in the future (89% of African American students and 97% of Latino students, with a P < 0.05 calculated using a two-sample t test).  However, it should be noted that more than half (54%) of the total students reported that although they planned to apply the sunscreen daily, they deemed it too expensive, which might prevent consistent future use. CONCLUSIONS: Our hypothesis in this dermatologic health literacy study was that before necessary education, the required fund of knowledge with respect to skin cancer risk is lacking in several ethnic communities, but that intended compliance occurs when educational intervention occurs.  The data, both quantitative and qualitative, demonstrate that our hypothesis is substantiated.
