1/46. Photosensitivity due to alprazolam with positive oral photochallenge test after 17 days administration.

    We describe a 65-year-old male patient with photosensitivity due to alprazolam. A photopatch test was negative. An oral photochallenge test after taking alprazolam for 17 days with UVA irradiation was positive. alprazolam, a lipid-soluble drug, may require long duration of administration to cause photosensitivity.

2/46. Urticarial eruption associated with rheumatic fever in a child.

    The classic description of erythema marginatum is of a few asymptomatic erythematous patches or plaques with a characteristic central clearing which may coalesce and develop a polycyclic configuration. We report a boy with a urticarial eruption without the classic lesions of erythema marginatum in whom the diagnosis of rheumatic fever was subsequently made. histology of the urticarial lesions revealed a mixed, superficial, perivascular infiltrate with prominent eosinophils. rheumatic fever should be considered in children with fever and urticaria-like eruptions even in the absence of the classically described erythema marginatum.

3/46. Prolonged erythema after facial laser resurfacing or phenol peel secondary to corticosteroid addiction.

    BACKGROUND: Prolonged persistent erythema postprocedure using phenol or carbon dioxide (CO2) lasers occurs frequently and the reasons have not been fully ascertained. OBJECTIVE: To describe patients whose postoperative care consisted of prolonged use of topical corticosteroids and to assess the outcome of cessation of this medicine. methods: Twelve patients who underwent CO2 laser resurfacing or phenol peels to their face are presented. All patients were seen between 3 and 30 months after the procedures were performed. All dressings, wound care, and other medicaments had been stopped prior to being seen. Most were patch tested to a wide variety of chemicals including corticosteroids, topical medications, and preservatives. They were observed during the poststeroid cessation period and the clinical response is described. RESULTS: All patch testing showed insignificant results. All postpeel patients cleared within 6 months of steroid cessation, experiencing several flares of erythema before the end result. Three of the six laser resurfacing patients cleared fully within 12 months and three are still being followed. The erythema and severe burning in the patients that cleared stayed clear during long-term follow-up. No scars or atrophy were seen. CONCLUSION: The use of topical corticosteroid preparations postoperatively in peel and resurfacing patients is believed to be a major cause of prolonged erythema, dermatitis, burning, and telangiectasias in these patients. The mechanism is believed to be one of vasoconstriction/vasodilatation secondary to the corticosteroids through a nonintact barrier.

4/46. Ectopic erythema migrans in an adolescent with a skin disorder.

    Red and white circular lesions of the buccal and labial mucosa were observed in an adolescent. Periodically, these nontender patches would resolve and move to other oral sites. Detection of ectopic erythema migrans aided in the diagnosis of a bothersome skin condition.

5/46. A case of erythrokeratoderma variabilis without mutations in connexin 31.

    Erythrokeratoderma (EK) variabilis is a heterogeneous group of diseases characterized by migratory erythematous patches and hyperkeratotic plaques. Mutations in connexin 31 have recently been found to underlie several cases of EK variabilis. We describe a Japanese girl with extensive lesions that appeared to be a form of EK variabilis, clinically resembling genodermatose en cocardes (Degos). Our patient had characteristic migratory rosette or target-like erythematous keratotic plaques with peripheral scaling in addition to relatively fixed keratotic plaques. Sequencing of the connexin 31 gene did not detect mutations. Skin biopsy showed parakeratotic hyperkeratosis with hypergranulosis. Immunohistochemically, suprabasal keratins, involucrin and profilaggrin were unequivocally expressed, while loricrin expression was greatly diminished and deiminated K1 was undetectable. Our results confirm aetiological heterogeneity in EK. The histological features suggest disruption of keratinocyte terminal differentiation at a very late stage.

6/46. Erythema dyschromicum perstans: a case report and review.

    Erythema dyschromicum perstans (EDP) is an acquired ashy dermatosis characterized by patches of blue-gray pigmentation over the trunk, extremities, and neck. These pigmentary changes may become chronic and disfiguring. At present, the etiology of EDP remains unclear, and there is no single established therapy. We describe a 21-year-old Hispanic man with extensive patches of EDP who improved with oral corticosteroid therapy.

7/46. Flexural erythematous eruption following autologous peripheral blood stem cell transplantation: a study of four cases.

    Autologous bone marrow transplantation and autologous peripheral blood stem cell transplantation (APBSCT) are alternative therapeutic options in the treatment of various malignancies. We describe four patients undergoing APBSCT for malignancies; they developed a cutaneous eruption characterized by confluent erythematous and hyperpigmented patches within the flexural areas during the first month after transplantation. The lesions were poorly circumscribed without epidermal changes such as scaling, xerosis, erosions or atrophy. The skin patches were treated with topical corticosteroids and resolved within a few days with discoloration. Histopathological findings were characterized by focal vacuolar degeneration of the basal layer with epidermal dysmaturation. We believe that these cutaneous eruptions are consistent with an interplay of high-dose chemotherapy and local factors such as friction, local skin temperature and eccrine gland distribution, which could explain the constant location of this eruption in the axillae and genital area.

8/46. Graham Little-Piccardi-Lassueur syndrome: effective treatment with cyclosporin A.

    Graham Little-Piccardi-Lassueur syndrome (GLPLS) is a rare lichenoid dermatosis defined by scarring alopecia, loss of pubic and axillary hairs and progressive development of horny follicular papules variously located. Topical or systemic corticosteroids, retinoids or puva therapy are the treatments usually proposed and these have partial and temporary benefits. We describe the effectiveness of cyclosporin A in a case of GLPLS at the dosage of 4 mg/kg/day. At the end of treatment, substantial reduction of both perifollicular erythema and follicular hyperkeratotic papules was observed. After 3 months of follow-up, besides the results already obtained, a few areas of hair regrowth in the scarring patches and a more consistent improvement of the follicular papules were detected. We believe that cyclosporin A could be effective mainly in the initial phases of this rare variant of lichen planopilaris, before the development of severe follicle damage, either by interfering with the acute inflammatory processes or by limiting the progression of the disease. To the best of our knowledge, this is the first report showing a good and persistent therapeutic effect of cyclosporin A in GLPLS.

9/46. Erythema gyratum atrophicans transiens neonatale.

    An unknown dermatosis was observed in an infant girl. During the newborn period, she had a generalized, patchy, erythematous eruption of about 60 round erythematous patches on the trunk, thighs, head, labial mucosa, and palate. After a few weeks, the lesions became whitish, atrophic, and depressed, and they were surrounded by an erythematous and slightly infiltrated border, which was occasionally lobulated. Histologically, the lesions demonstrated a thin epidermis overlying an edematous dermis. Around the border of the lesions the collagen bundles were infiltrated with mononuclear cells. Granular deposits of IgG, C'3, and C'4 were found at the dermoepidermal junction and around the superficial capillaries. The lesions healed completely and spontaneously within a year.

10/46. EMLA cream-induced irritant contact dermatitis.

    BACKGROUND: The Eutectic Mixture of Local anesthetics (EMLA cream) is a topical anesthetic used for providing pain relief in patients undergoing superficial surgical procedures. Cutaneous side-effects have been reported rarely. CASE REPORT: We present a case of irritant contact dermatitis induced by EMLA cream in a 6-year-old boy with wiskott-aldrich syndrome. Our patient showed clinically a well circumscribed patch corresponding to the site of application of the topical anesthetic. Histopathology showed confluent necrosis of keratinocytes in the upper epidermis, a mixed inflammatory infiltrate with priminent neutrophils in the upper dermis, and focal signs of interface changes including basal cell vacuolization and subepidermal cleft formation. CONCLUSIONS: Graft-vs.-host-disease (GVHD), necrolytic migratory erythema, dermatitis enteropathica and pellagra should be considered in the histopathologic differential diagnosis of acute contact dermatitis caused by EMLA.
