Abstract
Drug reaction with eosinophilia and systemic symptoms (DRESS) is a severe, drug-induced reaction that involves both the skin and the viscera. Evidence for reactivation of herpes family viruses has been seen in some DRESS patients. To understand the immunological components of DRESS and their relationship to viral reactivation, we prospectively assessed 40 patients exhibiting DRESS in response to carbamazepine, allopurinol, or sulfamethoxazole. Peripheral blood T lymphocytes from the patients were evaluated for phenotype, cytokine secretion, and repertoire of CD4+ and CD8+ and for viral reactivation. We found Epstein-Barr virus (EBV), human herpes virus 6 (HHV-6), or HHV-7 reactivation in 76% of the patients. In all patients, circulating CD8+ T lymphocytes were activated, exhibited increased cutaneous homing markers, and secreted large amounts of tumor necrosis factor-alpha and interferon-gamma. The production of these cytokines was particularly high in patients with the most severe visceral involvement. In addition, expanded populations of CD8+ T lymphocytes sharing the same T cell receptor repertoire were detected in the blood, skin, liver, and lungs of patients. Nearly half of these expanded blood CD8+ T lymphocytes specifically recognized one of several EBV epitopes. Finally, we found that the culprit drugs triggered the production of EBV in patients' EBV-transformed B lymphocytes. Thus, cutaneous and visceral symptoms of DRESS are mediated by activated CD8+ T lymphocytes, which are largely directed against herpes viruses such as EBV.

Abstract
AIMS The treatment of dermatofibrosarcoma protuberans (DFSP) involves wide local excision with frequent need for reconstructive surgery. A t(17;22) translocation resulting in COL1A1-PDGFB fusion is present in >95% of cases. Certain patient observations and a report on nine patients suggest that imatinib mesylate, targeting platelet-derived growth factor receptor beta, has clinical potential in DFSP. The primary aim of this phase II multicenter study was to define the percentage of clinical responders (Response Evaluation Criteria in Solid Tumors) to a 2-month preoperative daily administration of 600 mg of imatinib mesylate before wide local excision. The secondary aims were to determine tolerance, objective response from imaging results (ultrasound and magnetic resonance imaging), and pathologic responses observed in sequential tissue specimens. PATIENTS AND METHODS A two-stage flexible design was used with interim analysis after the recruitment of six patients. Twenty-five adults suffering from primary or recurrent DFSP were included from July 2004 to May 2006. RESULTS The COL1A1-PDGFB fusion gene was detected in 21 out of 25 patients following fluorescence in situ hybridization analysis (two cases were noninformative). A clinical response was achieved in nine (36%) patients (95% confidence interval, 18.9-57.5). The median relative tumoral decrease was 20.0% (range, -12.5 to 100). Apart from expected grade 1 or 2 side effects, we observed one grade 3 neutropenia, one grade 3 maculopapular rash, and one grade 4 transient transaminitis. CONCLUSION Our results support the use of imatinib in a neoadjuvant setting in nonresectable DFSP, or when surgery is difficult or mutilating. These results will be useful for setting hypotheses in the evaluation of new drugs to treat primary or secondary resistance to imatinib.

Abstract
BACKGROUND The LRINEC score was developed in a retrospective study in order to distinguish necrotizing fasciitis from severe soft tissue infections using laboratory data. AIM To evaluate the prognostic value of the LRINEC score in infectious cellulitis. PATIENTS AND METHODS A prospective study was performed at the departments of infectious diseases and dermatology of the Clermont-Ferrand University Hospital. The three evaluation criteria were: time from initiation of antibiotics to regression of erythema, duration of fever and occurrence of complications (abscess, surgery, septic shock, necrotizing fasciitis, death, transfer to intensive care). Potential predictive variables were: LRINEC score>6 at admission, comorbidities, local appearance, clinical presentation and soft tissue ultrasound results. RESULTS Fifty patients were included. The rate of complications was higher for patients with a LRINEC score>6 (54%) than for patients with a score<6 (12%, P=0.008). However, a LRINEC score>6 on admission was not significantly associated with increased duration of erythema or of fever. Prior lymphoedema was associated with a better prognosis. DISCUSSION The LRINEC score may be a useful tool for the detection of complicated forms of soft tissue infections. Patients with a LRINEC score>6 on admission should be carefully evaluated (hospitalization, surgical assessment, close monitoring).

Abstract
BACKGROUND In a previous phase I clinical trial of dietary methionine (MET) restriction with cystemustine treatment for melanoma or glioma, we determined the optimal MET-free diet duration to be 1 day. On this basis, a phase II clinical trial was initiated to evaluate safety and efficacy of this combination. PATIENTS AND METHODS Twenty-two patients (20 with metastatic melanoma and 2 with recurrent gloma) received a median of 4 cycles of the association of a 1-day MET-free diet with cystemustine (60 mg/m(2)) every two weeks. RESULTS This association was well tolerated (toxicity and nutritional status). Toxicity remained mainly hematological and consisted of WHO grade 3-4 thrombocytopenia, leucopenia and neutropenia in 36, 27 and 27% of patients respectively. The median disease-free survival was 1.8 months and the median survival was 4.6 months, with 2 long-duration stabilizations. The plasmatic MET depletion obtained was of 40 + or - 31%.

Abstract
To identify proteins involved in melanoma metastasis mechanisms, comparative proteomic studies were undertaken on B16F10 and B16Bl6 melanoma cell lines and their subsequent syngenic primary tumours as pulmonary metastases were present only in the mice bearing a B16Bl6 tumour. 2DE analyses followed by MALDI-TOF identification showed variations of 6 proteins in vitro and 13 proteins in vivo. Differential expressed proteins in tumours were related to energy production and storage. Two differentially expressed proteins which had not been previously associated to melanoma progression, annexin A1 (ANXA1) and creatine kinase B (CKB), were found both in cells and in tumours. To characterize ANXA1 involvement in melanoma B16 dissemination, we reduced ANXA1 protein level by siRNA and observed a significant decrease of B16Bl6 cell invasion through Matrigel coated chambers. We further demonstrated that the presence of several formyl peptide receptors (FPR1, FPRrs1 and 2) revealed by qRT-PCR, played a role in B16 invasion: incubation of B16Bl6 cells with the FPR agonist (fMLP) or antagonist (tBOC) enhanced or decreased Matrigel coated chamber invasion respectively, with a correlation of ANXA1 levels in both treatments. As ANXA1 could bind to FPRs, this should amplify invasion and enhance melanoma dissemination.

Abstract
BACKGROUND In the last two decades, there has been an increasing use of isotretinoin (13-cis-retinoic acid or 13-CRA) for treatment of severe, and recently mild and moderate, acne in Westernized populations. Recent human and animal studies emphasized alterations caused by 13-CRA administration on folate-dependent, one-carbon metabolism. Folate deficiency and subsequent hyperhomocysteinemia increase the risk of degenerative diseases. OBJECTIVES We determine whether a short-term supplementation with 13-CRA alters folate status and homocysteinemia in young and elderly healthy human subjects. METHODS Twenty young and 20 elderly (age mean, 26.1 and 65.4 years, respectively) healthy male volunteers were supplemented with approximately 0.5 mg/kg/day of 13-CRA for 28 days. Fasting plasma concentrations of 13-CRA, 5-methyltetrahydrofolate (5-mTHF) as the main circulating form of folate, and homocysteine (Hcy), as well as haematologic parameters and biochemical markers of liver and renal function, were measured at baseline and at the end of supplementation. Statistical analyses were carried out using two-way anova and standard tests. RESULTS In both groups, isotretinoin supplementation caused a dramatic increase in the circulating concentration of 13-CRA and its derivatives. It also led to significant increases in serum triglyceride (P < 0.0001) and creatinine (P = 0.002) concentrations and gamma-glutamyltranspeptidase activity (P = 0.0001) and decrease in serum level of urea (P = 0.027). However, the latter four parameters remained within normal ranges. These changes were accompanied by a 17.7% and 13.5% decrease in the plasma level of 5-mTHF (P = 0.001) in the young and elderly volunteers, respectively. Supplementation with 13-CRA did not cause significant variations in their plasma Hcy concentration. However, the latter parameter seemed to respond differently in each group of age (P = 0.046). CONCLUSIONS Our data indicate that a 28-day supplementation with isotretinoin alters the plasma folate in young and old healthy individuals. This stresses the necessity of studying the long-term effects of retinoid therapy on folate status and homocysteinemia in acne patients, given that alteration in the latter parameters is known to increase the risk of degenerative diseases.

Abstract
BACKGROUND The immunomodulatory effect of extracorporeal photochemotherapy (photopheresis) coupled with its efficacy in lymphocytic skin diseases provides a rationale for its use for erosive lichen planus. We report two cases of chronic oral erosive and corticoresistant lichen planus successfully treated with photopheresis. PATIENTS AND METHODS Case 1. A 61-years-old man had erosive oral lichen planus for four years. Oral steroids were contra-indicated due to iatrogenic pancreatitis. After nine photopheresis sessions, subjective improvement occurred and the oral lesions were stabilized. Case 2. A 17-years-old woman presented corticodependent oral and genital erosive lichen planus and cutaneous lesions. After seven sessions of photopheresis, the patient was able to eat again and the pain decreased. After 20 sessions, the cutaneous lichen planus disappeared and complete remission of the mucous lesions was obtained without corticotherapy. DISCUSSION These two cases, together with 23 other cases reported elsewhere, strongly suggested the value of photopheresis in the treatment of erosive lichen planus. However, relapses after treatment withdrawal appear extremely frequent.

Abstract
BACKGROUND Extracorporeal photochemotherapy (ECP) gives positive results in the management of graft-versus-host disease (GVHD), but in children, specific difficulties can outweigh this benefit. These difficulties must be taken into consideration when establishing a standardized reproducible procedure for implementation under a quality management plan. STUDY DESIGN AND METHODS Twenty-seven children underwent ECP for severe acute GVHD (aGVHD) or chronic GVHD (cGVHD) after allogeneic marrow transplantation. Data were collected prospectively, with particular emphasis placed on technical, biologic, immunologic, clinical, and long-term follow-up issues. RESULTS The 27 children underwent a total of 750 sessions. Mononuclear cells were collected on a commercially available apheresis system (COBE Spectra, Gambro BCT). Overall survival was 73 percent, and ECP led to significant improvement in 21 of the 27 patients (11 with complete response and 10 with partial response, i.e., >50% of organ involvement). Tolerance was good overall, the main limiting factors being vascular access and the psychological impact of repeated apheresis procedures. Children weighing less than 25 kg were not more susceptible to side effects. CONCLUSION A specifically pediatric-dedicated and -experienced team faces only limited difficulties when treating children with GVHD by ECP. Overall, ECP is efficient and well tolerated. Our experience was therefore pooled together with available pediatric data to establish clinical practice guidelines. These guidelines consider ECP as a first-line therapy in Grade IV aGVHD (in association with conventional pharmacologic approaches) and limited cGVHD and as a second-line therapy in steroid-resistant Grades II to III aGVHD and extensive cGVHD.

Abstract
BACKGROUND Unexpected cases of bullous pemphigoid (BP) have been reported in adult patients with various neurological disorders suggesting a possible relationship between these diseases. OBJECTIVES (1) To determine the prevalence and types of neurological disorders in patients with BP, (2) to assess patients' functional impairment, and (3) to compare the clinical and biological findings as well as prognosis of BP patients presenting with or without neurological disorders. METHODS BP patients with neurological disorders were selected in a series of 341 consecutive BP patients treated in 20 French Dermatology Departments. Functional impairment was prospectively assessed using the Karnofsky score which is a measure of patients' general condition. RESULTS At least one neurological disorder was present in 123 of the 341 BP patients (36%). They primarily consisted of dementia (n = 68; 20%; 95% CI: 16-25%), cerebral stroke (n = 52; 15%; 95% CI: 4-19%), and/or Parkinson's disease or parkinsonism (n = 32; 9%; 95% CI: 7-13%). BP patients with neurological disease were older than patients without neurological disease (83.8 +/- 7.5 years vs. 79.3 +/- 10.3 years, p < 10(-4)). They also had a lower Karnofsky score (47 +/- 19% vs. 74 +/- 20%, p < 10(-4)). One-year overall survival rates of the two groups were 50.8% (95% CI: 41.8-59.7) and 78.7% (95% CI: 73.0-84.2), respectively (p < 10(-4)). In contrast, the number of bullae and main biological features at baseline were not different between the two groups of patients. CONCLUSION This study demonstrated a high frequency of neurological disorders, particularly dementia, in BP patients. Most of these patients had a severe functional impairment and a poor prognosis.

Abstract
BACKGROUND The combination of multiple cycles of rituximab and intravenous immune globulins has been reported to be effective in patients with severe pemphigus. The aim of this study was to assess the efficacy of a single cycle of rituximab in severe types of pemphigus. METHODS We studied 21 patients with pemphigus whose disease had not responded to an 8-week course of 1.5 mg of prednisone per kilogram of body weight per day (corticosteroid-refractory disease), who had had at least two relapses despite doses of prednisone higher than 20 mg per day (corticosteroid-dependent disease), or who had severe contraindications to corticosteroids. The patients were treated with four weekly infusions of 375 mg of rituximab per square meter of body-surface area. The primary end point was complete remission 3 months after the end of rituximab treatment; complete remission was defined as epithelialization of all skin and mucosal lesions. RESULTS Eighteen of 21 patients (86%; 95% confidence interval, 64 to 97%) had a complete remission at 3 months. The disease relapsed in nine patients after a mean of 18.9+/-7.9 months. After a median follow-up of 34 months, 18 patients (86%) were free of disease, including 8 who were not receiving corticosteroids; the mean prednisone dose decreased from 94.0+/-10.2 to 12.0+/-7.5 mg per day (P=0.04) in patients with corticosteroid-refractory disease and from 29.1+/-12.4 to 10.9+/-16.5 mg per day (P=0.007) in patients with corticosteroid-dependent disease. Pyelonephritis developed in one patient 12 months after rituximab treatment, and one patient died of septicemia 18 months after rituximab treatment. These patients had a profound decrease in the number of circulating B lymphocytes but normal serum levels of IgG. CONCLUSIONS A single cycle of rituximab is an effective treatment for pemphigus. Because of its potentially severe side effects, its use should be limited to the most severe types of the disease. (ClinicalTrials.gov number, NCT00213512 [ClinicalTrials.gov].).

Abstract
BACKGROUND Methionine (MET) depletion used in association with chemotherapy improves the therapeutic index in animal models. This potentiating effect may be due to tumor cell sensitization to chloroethylnitrosoureas through their MET dependency and the down-regulation of O6- methylguanine-DNA methyltransferase (MGMT). Our purpose was to evaluate the impact of the association of a dietary MET restriction with nitrosourea treatment on MGMT activity in peripheral blood mononuclear cells (PBMCs). PATIENTS AND METHODS Six patients with metastatic cancer (melanoma and glioma) received 4 cycles of a MET-free diet with cystemustine (60 mg/m2). RESULTS MGMT activity in PBMCs decreased by an average of 13% from 553+/-90 fnol/mg before the diet to 413+/-59 fmol/mg after the diet + chemotherapy period (p=0.029). The decrease of MGMT activity was not affected by the duration of the MET-free diet period but seems to be correlated to the plasma MET depletion induced by the MET-free diet.

Abstract
BACKGROUND Erosive pustular dermatosis of the legs is a rare and recently described condition seen in elderly subjects. It is characterised by symmetric erosions of the legs resulting from a confluence of sterile pustules, usually following minor trauma. Treatment with dermal corticosteroids is rapidly effective but is not codified and relapse is common. CASE-REPORTS Three patients aged respectively 74, 84 and 92 years presented ulcers of the legs and ankles associated with peripheral pustules following minor injury. These pustules were sterile and exhibited a spongiform appearance on histological examination. None of these patients had a prior history of psoriasis. However, all presented zinc deficiency. Treatment with dermal corticosteroids combined with oral zinc gluconate resulted in complete resolution in two of the patients after several days of therapy and proved effective during relapse in the third patient. DISCUSSION Erosive pustular dermatosis of the legs is a benign dermatosis that is probably under-reported that should be included in the category of inflammatory neutrophilic dermatoses. The cases we present suggest a triggering or enhancing role of zinc deficiency.

Abstract
Several reviews and guidelines on the management of mycosis fungoides and Sézary syndrome (MF/SS) have been published; however, treatment strategies for patients with MF/SS vary from institution to institution and no European consensus has yet been established. There are few phase III trials to support treatment decisions for MF/SS and treatment is often determined by institutional experience. In order to summarise the available evidence and review 'best practices' from each national group, the European Organisation for Research and Treatment of Cancer (EORTC) Cutaneous Lymphoma Task Force met in September 2004 to establish European guidelines for the treatment of MF/SS. This article reviews the treatment regimens selected for inclusion in the guidelines and summarises the clinical data for treatments appropriate for each stage of MF/SS. Guideline recommendations are presented according to the quality of supporting data, as defined by the Oxford Centre for Evidence-Based Medicine. Skin-directed therapies are the most appropriate option for early-stage MF/SS and most patients can look forward to a normal life expectancy. Patients with advanced disease should be encouraged to participate in clinical trials and maintenance of quality of life should be paramount.

Abstract
BACKGROUND Necrobiotic xanthogranuloma is an extremely rare form of histiocytosis that presents clinically as yellowish infiltrated plaques or nodules. Ocular involvement is seen in over 80% of cases. Histopathology reveals numerous xanthomous histiocytes and collagen necrobiosis. Benign monoclonal gammopathy associated with myeloma is found in 80% of patients, but the course is normally long, with 100% survival at 10 years. CASE REPORT A 76-year-old man presented skin lesions that subsequently became ulcerated. The clinical appearance and histopathological examination resulted in diagnosis of necrobiotic xanthogranuloma. No monoclonal gammopathy or myeloma was seen. The disease was marked by sensitivity to corticosteroids with failure of other therapies (cyclophosphamide, alpha interferon), onset ofcorticosteroid dependency, iatrogenic Cushing's syndrome and diabetes, which were in part responsible for the infectious complications and subsequent death of the patient. DISCUSSION Necrobiotic xanthogranuloma is difficult to treat, even in the absence of myeloma or monoclonal gammopathy. Corticosteroids are probably the most efficacious treatment, but can give rise to multiple complications, resulting in this particular case in death of the patient.

Abstract
Background Median survival of metastatic malignant melanoma is 6.0 to 7.5 months, with a 5-year survival of ~6.0%. Although long-term complete remissions are rare, few reports describe cases after chemotherapy. Fifty-three patients with metastatic melanoma were treated with Cystemustine, a chloroethyl nitrosourea (CENU) (60 or 90 mg/m2). Case presentation We describe 5 cases, presenting with complete response with long-term disease-free survival of long-term remission of 14, 12, 9, 7 and 6 years after Cystemustine therapy alone. Conclusion Long-term survival has already been described in literature, but in all cases they have been obtained after chemotherapy associated with or followed by surgery. But despite these noteworthy and encouraging but also rare results, it appears essential to increase cystemustine efficiency.

Abstract
Nitrosoureas possess some anti-tumor activity as a single agent in metastatic melanoma (MM). In a phase II trial, we evaluated the anti-tumor effects of cystemustine chemotherapy, a new nitrosourea, as a second-line treatment. Patients were required to have histologic evidence of disseminated MM and had failed in first-line chemotherapy. Treatment comprised cystemustine given at a dose of 60 mg/m every 2 weeks by a 15-min infusion. From February 1997 to September 1999, 22 patients (median age 66 years) were enrolled and were assessable. Two complete responses, one partial response, three stable diseases and 16 progressions were observed, giving an overall response rate of 13.6%. Median duration of response was 10 months (range 4-63). Median survival of responders and non-responders was 11 and 4 months, respectively. However, hematological toxicity, particularly thrombopenia, was a limiting factor for one-third of patients. We conclude that cystemustine at 60 mg/m is active in patients who progressed after one line of chemotherapy in advanced disease, and offers the possibility of complete responses and long durations of these responses.
