Contact dermatitis due to printer's ink in a milk industry employee: case report and review of the allergen paraphenylenediamine.

Paraphenylenediamine is a common cause of occupational dermatoses in hairdressers, metallurgy workers, and others. Hand dermatitis developed in an employee of a milk packaging facility. The employee's hands were exposed to milk cartons embossed with wet printer's ink on a daily basis for 2 years. The worker was evaluated through a history, physical examination, and patch testing with 50 standard allergens. Patch testing revealed a positive reaction to paraphenylenediamine. The hand dermatitis resolved once the patient instituted protective measures. The worker's reaction might represent a delayed-type hypersensitivity reaction to printer's ink that contained this agent. More likely, the inciting agent was some other ingredient of the printer's ink that cross-reacts with paraphenylenediamine.

Contact urticaria from xylene.

Xylene is widely used in medical technology, but there are many concerns about its safety. A 52-year-old woman, employed as a histotechnician, presented with burning, swollen hands. Patch testing and a visit to her place of work confirmed exposure and sensitivity, in the form of contact urticaria, to xylene. The use of xylene-resistant gloves resulted in clearing of the dermatitis. Establishing the diagnosis of contact urticaria from xylene allowed the patient to be cured of her dermatitis and continue working.

Chloroxylenol causing hand dermatitis in a plumber.

Chloroxylenol use has increased and is found in many over-the-counter preparations. Although not a common sensitizer, chloroxylenol's role as a contact allergen and relevance, when positive patch tests are found, is often high. Pre-patch test assessment generally does not identify chloroxylenol as a causative agent. It is increasingly found in liquid soaps particularly in industry and specifically in the health care environment. Even as a wash-off product, this allergen can be a hidden cause of allergic contact dermatitis.

Contact dermatitis to foods and spices.

Cutaneous reactions to foods and spices occur in both the workplace and at home in those who grow, handle, prepare, or cook food. As spices are also used in cosmetics and perfumes other exposures are found. Several patterns have been described upon contact with food including irritant contact dermatitis, allergic contact dermatitis, contact urticaria, phototoxic contact dermatitis, and protein contact dermatitis. The purpose of this article is to review the approach to a patient suspected of having a cutaneous reaction to food or spices, as well as discuss these reactions and the allergens that cause them.

Elephantiasis nostras of the lips: a case report.

Elephantiasis nostras (EN) is a clinical entity that usually presents as a persistent swelling of the lower extremities. It has been related to recurrent lymphangitis of bacterial origin that causes a fibrosis and thickening of both epidermal and connective tissue. Although very rare, EN has been previously reported in the lips. This is the first case reported in the oral medicine literature that describes EN involving the lips. We describe the clinical features and a differential diagnosis of the lip lesions and a treatment protocol to which this patient has responded. A diagnosis of EN should be entertained in patients with chronically edematous, scaling lip lesions.
