[Keratosis lichenoides chronica and prolonged exposure to infrared radiation].

Background: We report a case of keratosis lichenoides chronica and prolonged exposure to a source of heat (infrared radiation).

Case Report: A 35 year-old man was examined for a symmetric and reticulate dermatosis on the abdomen, the interior of arms and lower extremities. The lesions had progressed over several months.

[Contact dermatitis from polyacrylate in TENS electrode].

Introduction: Transcutaneous electric nerve stimulation (TENS) is useful for many chronic pains. It induces few serious side effects, but skin reactions are not rare. We report on two cases of contact dermatitis due to TENS electrodes by sensitization to the acrylate in TENS conductive gel.

Epidemiology of dermatophytoses in children living in northeast France: a 5-year study.

Dermatologic fungal infections are thought to occur less frequently in children than in adults. This study, performed over a 5-year period, emphasizes the interregional variability of dermatophytes that cause skin and cutaneous apprendageal diseases in children. In northeast France, two-thirds of dermatophytoses are due to zoophilic fungi, while they are most commonly caused by anthropophilic agents in the Paris region and in other countries.

Relevance of skin tests with drugs in investigating cutaneous adverse drug reactions.

Skin tests with drugs can be of value in investigating patients who have developed cutaneous adverse drug reactions (CADR), but their specificity and relevance remain to be determined. A false-positive result on skin testing can happen if it is not compared to results in control subjects. When performing intradermal tests (IDT), we have determined the lowest concentrations that induce false-positive results for many drugs, including betalactam antibiotics, cephalosporins, other antibiotics or non-steroidal anti-inflammatory drugs.

[Sensitization to resorcinol in a prescription verrucide preparation: unusual systemic clinical features and prevalence].

Background: Resorcinol is a rare sensitizer. In Lorraine, where it is used in high concentrations in an anti-wart ointment, this molecule has induced many cases of allergy. The purpose of this study was to describe clinical features in patients sensitized to resorcinol, to determine the incidence of sensitization in Lorraine and ascertain the occurrence of cross reactions with other phenolic pro-haptens.

[Cutaneous delayed hypersensitivity reactions to heparins and heparinoids].

Introduction: Due to cross-reactions between unfractionated heparins, low-molecular-weight heparins and sometimes heparinoids, cutaneous delayed hypersensitivity reactions might be a problem for the choice of therapeutic alternative. We report on two cases of sensitization to heparins and heparinoids.

Observations: One woman developed localized skin reaction to a low-molecular-weight heparin, then a generalized maculopapular rash when an intravenous injection of unfractionated heparins was performed.

[Lymphoma presenting as Sister Mary-Joseph's nodule].

Background: Cutaneous metastasis of the umbilicus is generally associated with intra-abdominal adenocarcinoma, rarely with a malignant hemopathy.

Case Report: We report a case of lymphoma presenting as Sister Mary-Joseph's nodule, in a 79-year-old man. Histology evidenced small-cell lymphoma.

An unusual form of Stevens-Johnson syndrome with subcorneal pustules associated with Mycoplasma pneumoniae infection.

We report a 10-year-old girl in whom Stevens-Johnson syndrome (SJS) (with acute gingivostomatitis and conjunctivitis) was associated with a pustular eruption clinically and histologically similar to Sneddon-Wilkinson subcorneal pustulosis. This is a very rare form of SJS, the true incidence of which is probably underestimated.

[Contact dermatitis due to ethyl alcohol: how to perform patch tests?].

Introduction: Ethyl alcohol sensitization is rare and can induce immediate contact urticaria or delayed eczema. Patch tests performed with ethanol can provoke an irritative reaction and are not well codified.

Case-reports: We report on 4 cases of contact dermatitis due to alcohol in 4 women.

[Ultra-late metastasis of melanoma with secondary dissemination along the venous stripping line].

Background: A woman was cured of a melanoma of the leg. She presented an ultra late recurrence 17 years later, then rapid and extensive recurrence immediately after venous stripping.

Case Report: In 1977, a 38-year-old woman was operated for a SSM melanoma of the calf.

[Radiodermatitis afer heart catheterization].

INCREASING INCIDENCE: The development of new interventional techniques in radiology, particularly angioplasty of the coronary arteries, has lead to a rise in the incidence of radioderimitis. Clinical presentations vary from skin rash to necrosis and chronic ulceration. Telangiectasic atrophy and poikilodermitis are also observed.

[Leg ulcers. Allergologic studies of 359 cases].

Introduction: Leg ulcers are a common disease in dermatology. Their social and economic implications are important, especially when contact dermatitis complicates these wounds.

Patients And Methods: In this study a total of 359 patients had contact dermatitis investigations over a period of 5 years.

The use of skin testing in the investigation of cutaneous adverse drug reactions.

Skin testing with the suspected compound has been reported to be helpful in determining the cause of cutaneous adverse drug reactions (ADRs), but the value and specificity of these tests need to be determined. In this study, 72 patients with presumed drug eruptions (27 maculopapular, 18 urticarial, seven erythrodermic, nine eczematous, four photosensitivity, three fixed drug eruptions, three with pruritus and one with acute generalized exanthematous pustulosis) were assessed. All had drug patch tests; 46 also had prick tests and 30 had intradermal tests (performed on hospitalized patients using a sterile solution of the suspected drug, diluted sequentially) with immediate and delayed readings.

Pemphigus vulgaris on an old surgical scar: Koebner's phenomenon?

Pemphigus is an autoimmune bullous skin disorder. Several cases have been reported to originate in traumatized areas or on a scar, suggesting Koebner's phenomenon. Pemphigus can either remain localized or subsequently extend.
