RESUMEN
BACKGROUND: Pain is the main adverse effect of photodynamic therapy (PDT) and few effective analgesic methods are currently available. Our aim was to evaluate the efficacy of hypnoanalgesia with the use of PDT. PATIENTS AND METHODS: Between August 2011 and February 2013, a hypnoanalgesia session was proposed to patients requiring PTD for the treatment of (pre)carcinomatous lesions. At the end of the hypnosis session, patients evaluated their pain on a numeric pain scale (NPS) of 0 to 10. RESULTS: Twelve patients of average age 74.6 years were included. The indication for PDT was actinic keratosis (AK) in 9 patients, 1 Bowen's disease of the penis, 1 mammary Paget's disease and 1 bowenoid papulosis of the penis. Hypnoanalgesia was effective in 8 patients with a mean pain evaluation score of 2.9/10 on the NPS. Six of these 8 patients had previously undergone treatment by PDT without hypnosis and with an average pain score of 8.3/10. DISCUSSION: Hypnoanalgesia appears to be of value for pain management with PTD. This method is simple, inexpensive and devoid of side effects, and it is active on both pain and anxiety. To improve the use of hypnoanalgesia in PDT, it would be necessary to have better knowledge of the predictive factors for pain in PDT, to determine how to best select patients "sensitive" to hypnosis, and to encourage the training of nurses and doctors in this method.

BACKGROUND: Arndt-Gottron scleromyxedema is characterized by cutaneous mucinosis occasionally associated with systemic disorders, and it has a chronic and unpredictable course. The lesions are due to abnormal fibroblastic activity leading to acid mucopolysaccharide deposits in tissue. We report the case of a 50-year-old woman treated with intravenous immunoglobulin (IVIG), with excellent results in terms of her cutaneous lesions. CASE REPORT: A 50-year-old woman presented with multifocal micropapular lesions and cutaneous sclerosis that progressively limited joint movement and mouth opening and which were associated with a circulating monoclonal IgG Kappa. Previous treatments, including steroids, PUVA therapy, interferon, acitretin, methotrexate, melphalan and D-penicillamin were either ineffective or were stopped because of adverse effects. IVIG resulted in a remarkable and durable response at decreased dosage (0.5 g/kg per day for 3 days) with a 2-month treatment interval. DISCUSSION: IVIG at a dose of 2g/kg for 5 days constitutes a valuable alternative treatment because of its immunomodulatory effect. In scleromyxedema without systemic lesions, we propose a maintenance regimen at lower dosage, i.e. 0.5 g/kg per day for 3 days. CONCLUSION: Since Arndt-Gottron scleromyxedema is a rare disease, no standardized treatment has been yet established. The combination of minimal adverse effects and real efficacy makes IVIG an interesting alternative treatment for this disease.

INTRODUCTION: Mycosis fungoides is a lymphoma, the classical clinical form of which involves erythematosquamous lesions. However, it can present various atypical aspects: hyper pigmentation or hypo pigmentation, suggestive of pyoderma gangrenosum or ichtyosis. We report a case of mycosis fungoides, unusual in its presentation in the form of centrifugal annular erythema. OBSERVATION: A 78 year-old man had developed a parapsoriasis in plaques for more than 20 years. In May 2002 he consulted because of the recent infiltration of one of the plaques, without concomitant pruritus. The clinical examination revealed 3 lesions of the popliteal groove of the right groin and the left cheek suggestive of centrifugal annular erythema. Histology, revealing Pautrier microabscesses, was compatible with the diagnosis of mycosis fungoides. Evolution was marked by the spontaneous regression of the plaque on the face and remission of the other two plaques after local treatment with chloromethin and topical corticosteroids. Nevertheless, new plaques appeared despite continued treatment, combined with PUVA therapy sessions. DISCUSSION: When searching the literature, we only found one other case of mycosis fungoides, the clinical aspect of which was a centrifugal annular erythema, but in which the histological examination confirmed the diagnosis of mycosis fungoides. Our case report is also unusual in the clinical regression of the lesion on the face, without treatment; this has only been reported in two cases. Mycosis fungoides can appear in various clinical forms. The centrifugal annular erythema form is rare, but this diagnosis should be evoked.

A five month old child with atopic dermatitis developed contact dermatitis to almond with positive patch test, positive prick test, and class 4 anti-almond IgE. Focal lesions of persistent eczema were correlated with application of almond oil for 2 month on cheeks and buttocks. The child had not ingested almond and her mother did not report almond intake during her breast-feeding. This observation points to the problems of possible percutaneous sensitisation to food proteins. The study of skin ointments containing components of food origin in 27 food sensitized atopic patients confirm that the choice of an ointment for lesional skin is of importance.

The prescription of methotrexate (MTX) in dermatology is nowadays restricted for two main reasons: the toxicity of the drug and the availability of less toxic treatments (phototherapy and etretinate) in its main indication: psoriasis. However, MTX remains very useful in severe psoriasis, to some extent, in various dermatological diseases, such as dermatomyositis. A perfect knowledge of its adverse effects (slight on the gastrointestinal tract and bone marrow, much more serious on the liver and lung) allows a reasonable use of the drug but cannot avoid the unpredictable hypersensitivity pneumopathy.

We report T6 antigen expression on keratinocytes in 11 cutaneous T lymphomas treated by PUVA therapy. This staining was absent before treatment. T6 reactivity was strictly limited to cell membrane. The nature of this expression is discussed, and it is suggested that it could be attributed to a passive diffusion from Langerhans's cells.

Contact dermatitis form Hippomane mancinella L. (manchineel) is commonly observed in Caribbean and Central American Coast land. Its sap from leaf exudate and from the fruit induce severe dermatitis that may involve oral, ocular, genital mucous membranes and skin, depending on the mediate or direct type of contact. Intense itching or burning sensation occurs within an hour and is followed by painful erythema, vesicles, bullae or pustulae, the latter being highly suggestive of mancheneel. Oropharyngeal and ocular lesions may by very severe. The brief delay and the burnlike appearance of the lesions suggest an orthoergic mechanism due to a caustic that could be similar to the substance identified in an other species of Euphorbiacae as phorbol esters. Traditional and native remedies are presented herein.
