RESUMEN
BACKGROUND: Current treatments for chronic lichen planus (LP) are often ineffective and may have significant adverse side effects. An alternative safe and effective treatment for recalcitrant LP is needed. OBJECTIVES: We sought to study the safety and efficacy of apremilast in the treatment of moderate to severe LP. METHODS: Ten patients with biopsy-proven LP received 20 mg of apremilast orally twice daily for 12 weeks with 4 weeks of treatment-free follow-up. The primary efficacy end point was the proportion of patients achieving a 2-grade or more improvement in the Physician Global Assessment (PGA) after 12 weeks of treatment. RESULTS: Three (30%) of the 10 patients achieved a 2-grade or more improvement in the PGA after 12 weeks of treatment; however, all patients demonstrated statistically significant clinical improvement with respect to secondary parameters between baseline and the end of treatment. LIMITATIONS: It may be difficult to generalize the results of this study to a larger patient population with LP because of our small sample size and lack of a control group. In addition, a longer treatment period or higher dose may have been needed for therapeutic efficacy. The safety and efficacy of long-term apremilast therapy is currently unknown. CONCLUSION: Apremilast may be efficacious in the treatment of LP, but double-blinded, controlled trials are necessary to thoroughly evaluate its safety and efficacy.

OBJECTIVES: To investigate possible changes in the demographics of patients with melanoma during a period of 22 years in one dermatopathology practice. METHODS: We performed a retrospective review of 1835 cases of in situ and invasive melanomas histologically diagnosed between 1989 and 2010 in a private dermatopathology laboratory in Norfolk, Virginia. The age and sex of patients with in situ and invasive melanomas were recorded and compared with similar data for patients from whom any histopathologic specimen was received during the same interval. These data were then compared with those in the national Surveillance, Epidemiology, and End Results (SEER) registry between 1989 and 2009. RESULTS: The number of melanomas diagnosed in the laboratory increased during the 22 study years, but the proportion of submitted specimens diagnosed as melanoma remained somewhat stable. Patient ages ranged from the teens to the ninth decade of life. The proportion of melanomas in the in situ stage gradually increased. Mean patient age rose from 52.4 years in 1989 to 60.7 years in 2010. Men and women aged 60 years and older made up an increasing proportion of melanoma cases. There also was a relative increase in the proportion of women in the 40- to 50-year-old age group and a slight increase among those aged 20 to 30 years, particularly for invasive lesions. In general, the trends were similar for in situ and invasive melanomas. Our data were consistent with the SEER data in showing a trend for decreasing proportion of melanomas in younger individuals, with a corresponding increase in the middle-age and older adult populations. Some differences between the two datasets emerged for men aged 70 to 80, women aged 60 to 70, and all patients aged 70 to 80. CONCLUSIONS: An increasing proportion of melanomas were diagnosed in older individuals. There also was a relative increase in women aged 40 to 50 years and a lesser increase in those aged 20 to 30 years. Our findings were consistent with the national trends observed in the SEER dataset.

To review the literature on atopic dermatitis (AD) clinical trials published in the United States between 2000 and 2009 to examine the representation of racial and ethnic minorities in those trials and determine the extent to which investigators reported on demographic variables and performed a subanalysis. A PubMed search was performed including all clinical trials for management of AD published between 2000 and 2009. Three reviewers analyzed articles matching the search criteria. Data recorded included incorporation of demographic data at baseline and in the analysis and result interpretations. Of 645 PubMed search results, only 78 articles originated in the United States and fit the search criteria; 59.5% of these included reports of race or ethnicity. Of the studies reporting race or ethnicity, the subject population mainly included 62.1% white, 18.0% black, 6.9% Asian, and 2.0% Hispanic. Despite increasing awareness in the United States of the importance of reporting demographic data in clinical trials, there has been no significant improvement in reporting in AD clinical trials over the past 10 years. When reporting occurs, the categorization of ethnicities, methods of reporting data, and incorporation of the data into the results are lacking or flawed. In addition, aside from blacks, U.S. minorities appear to be underrepresented in AD clinical trials.

The objective of the study was to catalog hair shaft abnormalities in individuals with ectodermal dysplasia (ED) syndromes using light microscopy and to compare findings with those in unaffected controls. Light microscopy was performed in a nonblinded manner on hair shafts from 65 participants with seven types of ED (hypohidrotic ED, ED-ectrodactyly-cleft lip or palate, ankyloblepharon-ectodermal defects-cleft lip and palate, Clouston syndrome, Goltz syndrome, Schopf-Schulz Passarge syndrome, and oculodentodigital dysplasia) and 41 unaffected controls. Hair donations were collected at the 28th Annual National Family Conference held by the National Foundation for Ectodermal Dysplasia. Control participants were recruited from a private dermatology practice and an academic children's hospital outpatient dermatology clinic. Sixty-five affected participants and 41 unaffected controls were included in the analysis. We assessed the hair shafts of ED and control participants for abnormalities visible using LM. Light microscopy identified various pathologic hair shaft abnormalities in each type of ED, although none of the findings were statistically significantly different from those of the control group. Light microscopy is a poor adjuvant tool in the diagnosis of ED syndromes. Most findings are nonspecific and not sufficiently sensitive.

Dermatofibrosarcoma protuberans (DFSP) is a rare soft tissue tumor arising in the dermis. It is notorious for high rates of local recurrence despite its low metastatic potential. Although the etiology is unknown, DFSP often is considered to arise within scars and at sites of prior vaccination or trauma. Clinically, DFSP can be highly variable and mimic other soft tissue proliferations. We present a case of recurrent DFSP arising at the site of a Rho(D) immune globulin (Rhlg) injection that was administered 7 years prior. We also discuss the diagnostic challenges of DFSP as well as the indolent and locally recurrent nature of the tumor. This case serves to remind dermatologists of the highly variable clinical appearance of DFSP as well as to warn against presumptive diagnoses of lesions that mimic keloids and hypertrophic scars.

Scurvy, or hypovitaminosis C, is an uncommon condition that exists today primarily within certain unique populations-particularly the elderly subjects, patients with neurodevelopmental disabilities or psychiatric illnesses, or others with unusual dietary habits. Vitamin C is an essential nutrient in the human body, and is important in synthesizing collagen factor whose faulty production is responsible for most of the clinical manifestations of scurvy. These clinical manifestations can include dystrophic or corkscrew hairs, gingival hyperplasia, and weakened blood vessel walls, causing bleeding in the skin, joints, and other organs. Although rare in the Unites States, the presence of scurvy should not be forgotten because of its presence among susceptible populations. Moreover, with its diagnosis, treatment and cure is one of the simplest in modern medicine. We report a case of scurvy in a 10-year-old autistic child.
