1/41. Allergic contact dermatitis from propellants in deodorant sprays in combination with allergy to ethyl chloride.

    Allergic contact eczema from the use of deodorant sprays is sometimes caused by sensitization to the propellants. Positive reactions were seen in three patients when patch testing to Freon 11 (trichloromonofluoromethane). One patient also reacted to Freon 12 (dichlorofluoromethane). Another patient had an eczematous eruption after ethyl chloride was sprayed on the skin prior to taking biopsy. The two other patients showed strongly positive patch tests with this compound. Further investigations of the sensitizing capacity propellants with chemical resemblance have to be carried out to solve the problem of cross-sensitization.

2/41. dermatitis causada por Hylesia metabus (lepidoptera: Hemileucidae) en la region costera del Estado del Delta del Amacuro, venezuela [dermatitis caused by Hylesia metabus (lepidoptera: Hemileucidae) in the costal region of the state of Delta Amacuro, venezuela]

    2 cases of acute dermatitis caused by butterfly Hylesia metabus in an area that so far has not been considered as endemic for this species were presented. The dermatitis observed in these individuals may be described as very circumscribed, pruriginous, erythematous generalized protruding papules that may be compared with urticaria, and with a variable degree oedema. Monomorphic eruption consisting in small hard papules crowned by a little vesicle was also present. The lesions of these 2 patients evolved with intensely pruriginous papules for a week and after that they healed without dermatological sequelae.

3/41. The diagnosis of lichen-planus-like contact dermatitis to chlorpheniramine maleate.

    In spite of the common use of the diagnostic category of lichen-planus-like contact dermatitis, we were unable to find established criteria for such a condition. An atypical distribution of otherwise typical lichen planus lesions is usually considered as a feature of a lichenoid eruption. When facing unusual or unexpected clinical features, it is always advisable to consider an adverse reaction to a medical intervention as a potential option. We report a lichen-planus-like eruption occurring after contact with a topical agent containing chlorpheniramine maleate. To our knowledge, this is the first reported case of lichen-planus-like contact dermatitis associated with chlorpheniramine maleate.

4/41. chlorpromazine photoallergy. Coexistence of immediate and delayed type.

    A 54-year-old woman had a recurrent pruritic eruption in light-exposed areas. She had a combination of three types of hypersensitivity to chlorpromazine, ie, allergic contact dermatitis, photocontact dermatitis, and immediate allergic photosensitivity. Immediate wheal reactions were found after long-wave ultraviolet light irradiation at photopatch test and intradermal injection sites with chlorpromazine. These responses were differentiated from phototoxic reactions. A positive passive transfer reaction was also observed. To my knowledge, chlorpromazine photosensitivity of the immediate type has not been previously described.

5/41. Long-standing dermatological manifestations in a patient with chronic heavy metal intoxication.

    A patient with chronic metal intoxication is described, presenting during four years after the cessation of her exposure to industrial substances, maculo-papular eruptions with several ulcerated lesions and excoriations on her abdomen and buttocks. She also had pallor of her face, greyish-dark discoloration of the hair, while the fingernails were brittle and sensitive. Scrupulous physical examination excluded further cutaneous involvement. The immunological workup revealed both phenotypic and functional defects in cellular immunity.

6/41. Lamotrigine-induced erythema multiforme mimicking contact dermatitis.

    erythema multiforme is an acute, hypersensitivity reaction of the skin often secondary to medications. Lamotrigine is a relatively new anticonvulsant medication approved for seizure and psychiatric disorders. Although the overall incidence of cutaneous reactions to lamotrigine is high, the incidence of serious eruptions such as erythema multiforme, stevens-johnson syndrome, and toxic epidermal necrolysis is low. Vigilant surveillance for any cutaneous eruption in patients on lamotrigine is important, particularly in the first 8 weeks, as prompt discontinuation of the medication can prevent progression. We report a case of erythema multiforme secondary to lamotrigine, which clinically resembled a contact dermatitis, and review the management of lamotrigine associated cutaneous eruptions.

7/41. A case of prurigo pigmentosa considered to be contact allergy to chromium in an acupuncture needle.

    A 53-year-old male developed prurigo pigmentosa on his back, after undergoing acupuncture for 3 years. The eruptions were ceased on discontinuing the therapy but recurred with its resumption. The acupuncture needle contained 18.12% chromium. Erythema was induced by patch testing with potassium dichromate, and a flare-up was observed in the area of the patch test on resumption of acupuncture. We consider that the eruptions were induced by contact allergy to the chromium component of the acupuncture needles.

8/41. Systemic allergic contact dermatitis from intravesical instillation of the antitumor antibiotic mitomycin C.

    6 cases of contact allergy to the antitumor antibiotic mitomycin C from intravesical instillation are described. Reports suggest that up to 9% of patients treated with mitomycin C for chemoresection/prevention of superficial bladder cancer will develop cutaneous side-effects. patients may present either with vesicular dermatitis of the hands and feet and/or dermatitis of the genitals, or with more widespread eruptions. Probably most, if not all, skin reactions are caused by contact allergy. The distribution is suggestive of systemic contact dermatitis from mitomycin C absorbed from the vesical mucosa.

9/41. Gypsy moth caterpillar dermatitis--revisited.

    Gypsy moth caterpillar dermatitis is a pruritic, papular, urticarial eruption on exposed skin that occurs most commonly after direct contact with the first instar larva of the gypsy moth (Lymantria dispar). We present two case reports to illustrate its clinical and histopathologic features. Both cases occurred during the spring of 1990 and coincided with the greatest infestation of L. dispar in the Northeast to date. The pathogenesis of this distinctive gypsy moth dermatitis most likely involves histamine release by the caterpillar and a delayed hypersensitivity reaction in its host.

10/41. Allergy and toxicodermia from shiitake mushrooms.

    skin and respiratory symptoms developed within 2 months of exposure in a patient involved in the commercial production of shiitake mushrooms. A diagnosis of contact urticaria and allergic contact dermatitis from shiitake mushrooms was confirmed by prick and patch tests. The respiratory symptoms, their timing, the presence of precipitating IgG antibodies to shiitake spores and increased amounts of inflammatory cells and T lymphocytes in bronchoalveolar lavage indicated allergic alveolitis (mushroom worker's disease). A generalized exanthem developed in a second patient after eating raw shiitake mushrooms. Reactions to prick and patch tests with shiitake mushrooms were negative. The skin eruption in this patient corresponded to the previously reported shiitake-induced toxicodermia.
