[Vaccination status in psoriasis patients on immunosuppressant therapy (including biologics)]. / Couverture vaccinale avant et après instauration d'un traitement immunosuppresseur (y compris biothérapie) pour psoriasis.

OBJECTIVES: To evaluate the vaccine coverage of psoriasis patients prior to initiating or changing immunosuppressant therapy, and to verify that the prescribed vaccines have been administered. PATIENTS AND METHODS: We conducted a bi-centre, observational, cross-sectional study over 9 months. Psoriasis patients in whom immunosuppressant therapy (comprising cyclosporine, methotrexate, etanercept, infliximab, adalimumab or ustekinumab) was indicated were included. Medical history, previous treatments, vaccination status, viral serology results (for hepatitis B, measles, and chickenpox), and reasons for non-vaccination were assessed via questionnaire. RESULTS: Sixty-eight patients were included. One third brought their immunization records. Overall, 54.4% had already received immunosuppressant therapy; of these, 9 were up to date for influenza and 3 were up to date for pneumococcus. Only one patient was up to date for all of the recommended vaccinations. A total of 61% of patients were seronegative for hepatitis B. The following vaccines were updated: DTP (in 2 patients), DTP-pertussis (12), influenza (22), pneumococcus (45), and hepatitis B (6). None of the three patients with plans to travel to yellow fever-endemic countries had been vaccinated. In all, 53 (78%) stated that they had already had chickenpox and 43 (63.2%) stated that they had had one of the following three diseases: measles, rubella, or mumps. Fifty-two patients were serologically tested for chickenpox, and 98% were immunized. The most common reasons for not updating the immunization schedule were the absence of any notification or proposal by the patient's doctor and oversight. CONCLUSION: This study should help raise awareness among patients and health professionals concerning the new vaccination recommendations for a population particularly at risk of infection.

Efficacy of neoadjuvant cetuximab alone or with platinum salt for the treatment of unresectable advanced nonmetastatic cutaneous squamous cell carcinomas.

BACKGROUND: Refractory locally advanced or metastatic nonmelanoma skin cancer (NMSC) is a frequent therapeutic impasse. OBJECTIVES: To address the question of the efficacy of induction therapy with cetuximab as neoadjuvant treatment for locally advanced NMSC. METHODS: From 2008 to 2013, all patients with a diagnosis of unresectable locally advanced skin squamous cell carcinoma were treated with neoadjuvant cetuximab alone (CM) or combined with a platinum salt and 5-fluorouracil (CC). Resectability, and clinical and pathological response, as well as relapse-free and overall survival were evaluated. RESULTS: Thirty-four patients, with a median age of 74·5 years, were evaluated. Twenty-five patients received CC. After three cycles of CC, 23 of 25 patients whose tumours were initially unresectable became amenable to surgery (92%). A complete histological response was observed in 15 (65%) patients. The mean progression-free and mean overall survival in operated patients were 8·5 and 26·0 months, respectively. CONCLUSIONS: There was a good response in terms of resectability and tumour control in the majority of patients, with few relapses, despite the initially poor prognosis of these tumours in this elderly group of patients. However, this therapeutic strategy needs to be validated in a prospective, randomized study.

[Linear tuberculoid leprosy along the lines of Blaschko: a very rare presentation]. / Lèpre tuberculoïde de disposition linéaire blaschkoïde: une présentation exceptionnelle.

BACKGROUND: Leprosy continues to be present in certain regions throughout the world, and the dermatologist plays a central role in its diagnosis. Herein we report a case of tuberculoid leprosy that is atypical in terms of its linear presentation which appears to follow the lines of Blaschko. PATIENTS AND METHODS: A patient from Mayotte was referred to the neurological department for suspected tuberculoid leprosy. He was presenting a deficiency of the ulnar nerve together with neuronal hypertrophy and cutaneous involvement. Dermatological examination revealed linear hypo-aesthetic hypopigmented lesions on the arm and forearm. The atypical clinical presentation also suggested to us pigmented mosaicism or post-inflammatory pigmentation. The biopsy showed granulomatous epithelial dermatitis with perinervous involvement. Imaging examinations confirmed the presence of neuronal hypertrophy. A diagnosis of linear tuberculoid leprosy was made. DISCUSSION: This case illustrates the need to bear in mind a diagnosis of leprosy in the event of hypopigmented lesions, even where they are linear and of Blaschkoid appearance. Several potential hypotheses may account for this particular topographical pattern.

[Case report of EPPER Syndrome (eosinophilic polymorphic pruritic eruption associated with radiotherapy) in a patient treated against endometrial cancer]. / À propos d'un syndrome EPPER (eosinophilic polymorphic pruritic eruption associated with radiotherapy) survenu chez une patiente après traitement d'un cancer de l'endomètre.

Acute and mainly late toxicity is a major concern for radiotherapists. Here, we describe a case of a generalized acute eruption due to radiation, having a superficial and deep perivascular lymphocytic infiltrate with numerous eosinophils found in skin biopsy: the EPPER syndrome (eosinophilic polymorphic pruritic eruption associated with radiotherapy). A patient who had endometrial cancer was treated first by surgery, then radiotherapy developed the day following the end of irradiation a generalized erythematous, pruriginous eruption (pelvis, trunk, lower and upper limbs, neck, face, ears). Different tests with a skin biopsy found a superficial and deep perivascular lymphohistiocytic infiltrate with many eosinophils, confirming an EPPER syndrome. The description of the syndrome was first published in 1999 by Rueda et al. (1999) [1]. Later on, there have only been a few case reports on this subject. This syndrome can be encountered in many cancers, but more frequently in cervix and breast carcinomas and can occur up to nine and a half months after radiotherapy. The pathogenic mechanism is unknown. Antihistamines, topical corticosteroids or oral corticosteroids as well as ultraviolet B therapy have been used successfully to treat EPPER syndrome. Some cases of spontaneous resolution are also described. EPPER syndrome is probably largely underestimated due to its polymorphic characteristics, its occurrence sometimes late after radiotherapy. Its knowledge is essential to inform and treat patients correctly.
