Lichen sclerosus among women in the United States.

Int J Womens Dermatol 2020 Sep 8;6(4):260-262. Epub 2020 May 8.

The Ronald O. Perelman Department of Dermatology, New York University School of Medicine, New York, NY, United States.

Background: Vulvar lichen sclerosus (LS) is a chronic dermatosis for which the true prevalence is not well established. LS remains an underrecognized and undertreated disease, and treatment patterns and differences among various specialties that care for patients with LS are largely unknown.

Objective: This study sought to determine the prevalence of diagnosed vulvar LS, demographic characteristics, and diagnostic and treatment patterns in the United States.

Methods: A database comprising >21.7 million women with commercial insurance in the United States was analyzed, and the largest cohort of patients with LS in the United States to date was identified.

Results: We found that obstetricians/gynecologists are diagnosing and managing approximately half of women with LS, and regardless of specialty, the majority of providers are appropriately prescribing high-potency topical steroids.

Conclusion: Our results suggest that LS may truly be underrecognized and underdiagnosed, especially in younger women.

Camouflaging vitiligo using a spray tan.

Dermatol Online J 2020 Jul 15;26(7). Epub 2020 Jul 15.

The Ronald O. Perelman Department of Dermatology, New York University School of Medicine, New York, NY.

Vitiligo is a depigmenting skin disorder that can cause significant patient distress. Treatment of vitiligo is challenging and should address patient's concern for cosmetic treatment. Herein, we report the case of a 60-year-old patient who achieved temporary improvement in pigmentation using a spray tan. Camouflaging vitiligo using a spray-tan is a reasonable, safe, and effective mechanism for management of vitiligo.

Comparison between organismal staining on histology and tissue culture in the diagnosis of cutaneous infection: A retrospective study.

J Am Acad Dermatol 2020 Jun 28;82(6):1400-1408. Epub 2020 Jan 28.

Ronald O. Perelman Department of Dermatology, New York University School of Medicine, New York, New York. Electronic address:

Background: In instances of suspected cutaneous infection, the standard of care includes obtaining skin biopsy specimens for histology and tissue culture. Few studies have compared the clinical utility of each test.

Objective: To assess the concordance of results between tissue culture and histology, as well as the clinicopathologic features that may influence the diagnostic yield of each test.

Methods: A retrospective review of all patients who underwent skin biopsy for histology and tissue culture at New York University from 2013 through 2018.

Results: Of 179 patients, 10% had positive concordance, 21% had positive tissue culture only, and 7% had positive histology only. We calculated a kappa correlation coefficient of 0.25 between histology and tissue culture (reference, 0.21-0.39 indicates minimal agreement). Histology exhibited higher sensitivity in detecting fungi, whereas tissue culture was more sensitive in identifying Gram-negative bacteria. Antimicrobial use before biopsy led to significantly fewer positive cultures (37.5% vs 71%; P = .023) in patients ultimately diagnosed with infection.

Limitations: This study was conducted at a single institution, thereby restricting its broad applicability. The lack of a validated criterion standard to diagnose infection also limits interpretation of the results.

Conclusion: Tissue culture and histopathology often yield discordant results. Dermatologists should recognize specific limitations, yet high clinical utility in special circumstances, of tests when approaching cases of suspected infection.

The color of skin: purple diseases of the skin, nails, and mucosa.

Clin Dermatol 2019 Sep - Oct;37(5):528-547. Epub 2019 Jul 17.

The Ronald O. Perelman Department of Dermatology, New York University School of Medicine, New York, New York, USA. Electronic address:

The color purple can be seen in several types of eruptions including inflammatory dermatoses like lichen planus, infectious dermatoses like ecthyma gangrenosum, neoplasms like Kaposi sarcoma, and vasculitis and vasculopathy. The current review focuses on the clinical appearance, pathophysiology, and treatment of several vasculitides and vasculopathies including capillaritis, cutaneous small-vessel vasculitis, immunoglobulin A (IgA) vasculitis, cryoglobulinemia, granulomatosis with polyangiitis, eosinophilic granulomatosis with polyangiitis, microscopic polyangiitis, polyarteritis nodosum, warfarin-induced skin necrosis, heparin-induced thrombocytopenia, purpura fulminans, antiphospholipid antibody syndrome, calciphylaxis, levamisole-induced vasculopathy, and thrombotic thrombocytopenic purpura. Dermatologists play a central role in treating patients with cutaneous vasculitis and vasculopathy and may have the opportunity to facilitate identification of systemic disease by diagnosing cutaneous vasculitis and vasculopathy.

The Ronald O. Perelman Department of Dermatology, New York University Langone Health, New York, New York.

The pathophysiology of generalized essential telangiectasia is not well understood. Generalized essential telangiectasia is an uncommon disorder in which widespread telangiectasias of unknown cause develop without associated systemic or antecedent dermatologic disease. We report a case of generalized essential telangiectasia in an otherwise healthy 49-year-old man.

Autoimmune Progesterone Dermatitis: A Diagnosis to Consider in a Patient With Cyclical Cutaneous Eruptions.

J Drugs Dermatol 2017 Oct;16(10):1040-1042

Autoimmune progesterone dermatitis (APD) is a cyclical cutaneous reaction to progesterone, with symptoms that typically begin 3-10 days before the onset of menstrual flow and end 1-2 days into menses. The symptoms vary in severity from barely visible to anaphylaxis, but most often include an eczematous eruption, erythema multiforme, urticaria, folliculitis, and angioedema. This is a rare disorder with only a handful of documented cases. The pathogenesis of this condition remains unknown and significant variations in the presentation and severity of symptoms complicates its diagnosis. Treatment seeks to inhibit progesterone secretion through suppression of ovulation, but it may be unsuccessful. We present a case of autoimmune progesterone dermatitis that eluded diagnosis for several years, and subsequently the patient was completely controlled with oral contraceptive pills.

Teens and tanning knowledge and attitudes.

J Clin Aesthet Dermatol 2009 Feb;2(2):48-50

Background: The incidence of skin cancer, including melanoma, continues to increase. Teenagers are especially vulnerable, as are young females. The incidence of melanoma among young women in their twenties and thirties has begun to increase again. These young people are also the population that frequent tanning salons.

Objective: This voluntary, anonymous, New York University, Institutional Review Board-approved survey was given to students in grades 9 through 12 to ascertain their understanding of what causes skin cancers and the dangers of excessive sun exposure and tanning salons.

Methods And Materials: An Institutional Review Board-approved, 22-question survey was administered anonymously to more than 450 students with 368 returned responses. The survey was administered to students in grades 9 through 12 at two high schools in New York and New Jersey.

Results: More than 80 percent of students view movie stars as tan and almost 60 percent see "tan" people as better looking. In addition, more than 90 percent believe that a tan does not prevent further damage to the skin (as opposed to the customary belief that a "base" tan can protect against extreme sun exposures, such as when on a tropical vacation). There appears to be a disconnect between knowledge and sun tanning behaviors. Most teenagers still believe that tans are attractive and teenage girls continue to use tanning salons and tan naturally. We need to address the connection between sun tanning in youth and skin cancers years later. Legislation to limit access of tanning salons to teenagers needs to be enacted.
