Verrucous and macular sarcoidosis
Defelice, Taylor; Fischer, Max; Kamino, Hideko; Cohen, David; Latkowski, Jo-Ann
We present a case of cutaneous sarcoidosis in a 77-year-old woman without systemic disease, who presented with two subtypes of lesions: erythematous and hyperpigmented macules on the arms and anterior upper legs and erythematous, hyperkeratotic nodules, some crateriform, on the lower legs and feet. Whereas cutaneous sarcoidosis is present in up to one-third of cases and may present with a wide variety of lesions, verrucous sarcoidosis is uncommon. Diagnosis is by clinical and histopathologic exclusion of other entities, which include other causes of granulomatous inflammation such as infections and foreign-body reactions. Management options include topical, intralesional, or systemic glucocorticoids, antimalarials, tetracycline derivatives, and methotrexate.

Morbihan disease
Hu, Stephanie W; Robinson, Maria; Meehan, Shane A; Cohen, David E
Morbihan disease, which consists of solid facial edema, is a rare complication of rosacea, a common cutaneous disorder in middle-aged individuals. The characteristic features of Morbihan disease are its chronic course, typical clinical picture, lack of specific laboratory and histopathologic findings, and refractoriness to therapeutic measures. Since its initial description in 1957, only a small number of cases have been reported in the dermatologic literature. We report a 54-year-old man who developed a two-year duration of erythema and edema that affects the upper and mid face, with accentuation in the periorbital region. Patch tests excluded an allergic contact dermatitis and histopathologic investigation showed small, nodular clusters of epithelioid cells in the dermis that were consistent with sarcoidal granulomata. A diagnosis of Morbihan disease was made owing to the combination of clinical and histopathologic findings. Therapeutic options for the disease remain unsatisfactory and treatments reported in the literature include systemic glucocorticoids, oral tetracyclines, thalidomide, isotretinoin, ketotifen, and clofazimine. Our patient failed a six-to-seven months course of minocycline prior to presentation and has since experienced improvement on gradually-increasing doses of isotretinoin.

Normal minimal erythema dose responses in patients with suspected photosensitivity disorders
Que, Syril Keena T; Brauer, Jeremy A; Soter, Nicholas A; Cohen, David E
PURPOSE: Our study identified the most common diagnoses in patients with a history of photosensitivity or with a photodistributed eruption and normal minimal erythema dose (MED) responses. METHODS: We retrospectively reviewed the diagnoses and phototest results of 319 patients who were phototested at the New York University Photomedicine Section of the Charles C. Harris Skin and Cancer Pavilion from 1993 to 2009. Patients were phototested if they had a history of photosensitivity or had an eruption with a distribution that suggested photosensitivity. RESULTS: The majority of patients with normal MEDs were diagnosed with polymorphous light eruption, followed by contact or photocontact dermatitis, photodistributed dermatitis not otherwise specified (idiopathic), solar urticaria and photoexacerbated atopic dermatitis. DISCUSSION: The clinical history of photosensitivity and physical findings remain as important metrics in the diagnosis of patients with photodistributed dermatoses and normal MEDs.

Why is rosacea considered to be an inflammatory disorder? The primary role, clinical relevance, and therapeutic correlations of abnormal innate immune response in rosacea-prone skin
Del Rosso, James Q; Gallo, Richard L; Kircik, Leon; Thiboutot, Diane; Baldwin, Hilary E; Cohen, David
The pathophysiology of rosacea has undergone renewed interest over the past decade, with a large body of evidence supporting the role of an abnormal innate immune response in rosacea. Many mechanisms interact with the cutaneous innate immune system that may be operative. A variety of potential triggers stimulate this immune detection system which is upregulated and hyper-responsive in facial skin of patients with rosacea as compared to normal skin. Based on the most current data, two conclusions have been reached. First, the major presentations of rosacea appear to be inflammatory dermatoses. Second, the presence of a microbial organism is not a primary or mandatory component of the pathogenesis of rosacea. Available therapies for rosacea exhibit reported modes of action that appear to correlate with the inhibition of inflammatory processes involved in the pathophysiology of at least some presentations of rosacea.

Hypersensitivity reactions to vaccine constituents: a case series and review of the literature
Leventhal, Jonathan S; Berger, Emily M; Brauer, Jeremy A; Cohen, David E
: Vaccines are composed of immunogens, preservatives, adjuvants, antibiotics, and manufacturing by-products. Components of vaccines may rarely elicit adverse reactions in susceptible individuals, thus raising concerns regarding vaccine safety. In this report, we add to the medical literature 3 cases of cutaneous delayed-type hypersensitivity to the vaccine preservative aluminum. We provide a review of major constituents in vaccines that have elicited immediate-type or delayed-type hypersensitivity reactions and describe their clinical manifestations. We include a table of the Food and Drug Administration-approved vaccines, which lists the quantities of major components including ovalbumin (egg protein), gelatin, aluminum, neomycin, 2-phenoxyethanol, thimerosal, and formaldehyde. Our goals were to inform physicians on the variety of hypersensitivity reactions to common vaccines and to provide information on the choice of vaccines in patients with suspected hypersensitivity.

The identification of a sensitizing component used in the manufacturing of an ink ribbon
Anderson, Stacey E; Tapp, Loren; Durgam, Srinivas; Meade, B Jean; Jackson, Laurel G; Cohen, David E
Skin diseases including dermatitis constitute approximately 30% of all occupational illnesses, with a high incidence in the printing industry. An outbreak of contact dermatitis among employees at an ink ribbon manufacturing plant was investigated by scientists from the National Institute for Occupational Safety and Health (NIOSH). Employees in the process areas of the plant were exposed to numerous chemicals and many had experienced skin rashes, especially after the introduction of a new ink ribbon product. To identify the causative agent(s) of the occupational dermatitis, the murine local lymph node assay (LLNA) was used to identify the potential of the chemicals used in the manufacture of the ink ribbon to induce allergic contact dermatitis. Follow-up patch testing with the suspected allergens was conducted on exposed employees. Polyvinyl butyral, a chemical component used in the manufacture of the ink ribbon in question and other products, tested positive in the LLNA, with an EC3 of 3.6%, which identifies it as a potential sensitizer; however, no employees tested positive to this chemical during skin patch testing. This finding has implications beyond those described in this report because of occupational exposure to polyvinyl butyral outside of the printing industry.

Self-reported skin rash or irritation symptoms among world trade center health registry participants
Huang, Monica J; Li, Jiehui; Liff, Jonathan M; Cohen, David E; Cone, James
OBJECTIVES: : We described self-reported skin rash 2 to 3 and 5 to 6 years after 9/11 and examined its association with exposures to 9/11 dust/debris. METHODS: : We analyzed a longitudinal study of New York City World Trade Center Health Registry participants who resided or worked in Lower Manhattan or worked in rescue/recovery in two surveys (W1 and W2). RESULTS: : Among 42,025 participants, 12% reported post-9/11 skin rash at W1, 6% both times, 16% at W2. Among participants without posttraumatic stress disorder or psychological distress, W1 self-reported post-9/11 skin rash was associated with intense dust cloud exposure (adjusted odds ratio [OR] = 1.6; 95% confidence interval [CI] = 1.3 to 1.9), home/workplace damage (adjusted OR = 1.8; 95% CI, 1.4 to 2.3), and working more than 90 days (adjusted OR = 1.7; 95% CI, 1.3 to 2.2) or 31 to 90 days (adjusted OR = 1.6; 95% CI, 1.3 to 2.1) at the World Trade Center site. CONCLUSIONS: : Post-9/11 skin rash may be related to acute and long-term exposure to dust, though subjectivity of skin symptoms may bias findings.

The changing roles of industry and academia
Bauer, Eugene A; Cohen, David E
Over the past 25 years both the quality and quantity of pharmaceutical and biopharmaceutical research has changed. Formerly rigidly separated research efforts in academic institutions and the biopharmaceutical industry have become increasingly transparent to one another. Industry has in some cases scaled down its internal research efforts, while enhancing its outreach to basic research in academic institutions. In parallel, research at academic institutions has-in some cases-added a focus on application of discoveries to patient needs. This porosity between industry and academia has created opportunities for more rapid translation of basic discoveries to patient needs. Additionally, both physicians and fundamental scientists have broadened their career opportunities, and movement between industry and academia-almost unheard of two decades ago-now occurs regularly. At the same time, numerous examples exist of how these translational efforts have benefited not only patients but also investigators and academic institutions as well. Despite many potential advantages of closer interactions between industry and academia, other issues, such as conflicts of interest (both real and perceived), continue to pose challenges.

The management of EGFR inhibitor adverse events: a case series and treatment paradigm
Wnorowski, Amelia M; de Souza, Aieska; Chachoua, Abraham; Cohen, David E
Background Epidermal growth factor receptor (EGFR) inhibitors are widely used medications in the treatment of cancers. Objective To review the cutaneous adverse events related to EGFR inhibitors. Methods A retrospective chart review of all cases referred for the management of cutaneous adverse events after the initiation of EGFR inhibitor therapy between the years of 2006 and 2009 was performed. The study was approved by the institutional review board. Results Four men and 11 women had cutaneous adverse events while receiving erlotinib (mean dose: 112.5 mg) for lung and pancreatic cancer. The most common cutaneous adverse reaction observed was a papulopustular rash in 12 cases (80%). Eczema and xerosis were the only findings in three patients, alopecia in one case, and nail changes in three cases. The treatment modalities prescribed were doxycycline and topical antibiotics for the papulopustular rash; topical high potency steroids, tacrolimus, pimecrolimus, and moisturizers for xerosis and eczema; and cetirizine for the pruritus. The paronychia was treated with warm soaks, topical steroids, and podiatry referral. The majority of patients improved with symptomatic therapy, with the exception of one patient who experienced herpes zoster super infection and Stevens-Johnson syndrome. The patient was hospitalized and required discontinuation of the erlotinib therapy. Conclusion The most common cutaneous adverse event in our cohort was papulopustular rash, followed by eczema and xerosis. Patients were managed with symptom target therapy, and suspension of the EGFR inhibitor was rarely required. As the use of EGFR inhibitors increases, it is important to promptly identify and treat adverse events. Further studies are necessary to develop targeted therapeutic and preventative measures
