Interstitial granulomatous dermatitis.

A 59-year-old woman with arthritis presented to the Skin Institute of New York with a 2-month history of asymptomatic, small, skin-colored papules that erupted symmetrically on the chest, back, and proximal extremities. Histopathologic examination of a biopsy specimen showed findings of interstitial granulomatous dermatitis. Clinical correlation suggested a diagnosis of interstitial granulomatous dermatitis with arthritis.

Use of the North American Contact Dermatitis Group Standard 65-allergen series alone in the evaluation of allergic contact dermatitis: a series of 794 patients.

Background: The "gold standard" for diagnosing allergic contact dermatitis is patch testing. Previous studies have not adequately addressed the validity and usefulness of the North American Contact Dermatitis Group (NACDG) Standard 65-allergen series alone as a screening tool in the evaluation of contact dermatitis.

Objective: The purpose of this study is to examine the usefulness of the NACDG series of 65 allergens as an exclusive screening method in the diagnosis of contact allergy.

Contact allergy to food.

Contact allergies to foods, spices, and food additives can occur to individuals in the workplace or at home. Seven different reaction types have been described. These include irritant contact dermatitis, allergic contact dermatitis, contact urticaria, protein contact dermatitis, phototoxic contact dermatitis, photo-allergic contact dermatitis, and systemic contact dermatitis.

Photocontact allergy to diallyl disulfide.

Although phototoxic reactions to plants are common, photoallergic contact dermatitis to plants and plant products rarely occurs. Our objective was to review the importance of including diallyl disulfide in the evaluation of patients with suspected photosensitivity. Phototests for ultraviolet B, ultraviolet A, and visible light as well as patch tests and photopatch tests for 49 allergens from the New York University Skin and Cancer Unit Photopatch Test Series were performed.

Systemic contact dermatitis to doxepin.

Although allergic contact dermatitis to topical preparations of doxepin has been published, systemic contact dermatitis from oral doxepin is more of a theoretical consideration and is rarely reported. We report a case of a patient with contact allergy to doxepin hydrochloride 5% cream who developed a systemic contact dermatitis to oral doxepin.

Identification and quantification of para-phenylenediamine in a temporary black henna tattoo.

Background: Temporary black henna tattoos are very popular as body adornment. Although contact allergy to natural henna is unusual, the inclusion of hair dye, p-phenylenediamine (PPD), increases the risk of contact sensitization.

Objective: This study was performed to identify the presence and concentration of PPD in a black henna tattoo mixture to which our patient developed contact allergy.
