[Borrelia strains that cause erythema migrans in Alsace, France].

INTRODUCTION: In Europe, Borrelia burgdorferi sensu stricto, Borrelia afzelii and Borrelia garinii are known as pathogens among the Borrelia burgdorferi sensu lato group. Since it is not yet known which Borrelia are responsible for Lyme borreliosis in France, the objective of this study was to identify the species of Borrelia responsible for erythema migrans in the region of Alsace, France. PATIENTS AND METHODS: Eighteen patients with erythema migrans (EM) of more than 5 cm of diameter were included in this prospective study. All patients were investigated at the Strasbourg University Hospital. Patients were biopsied on the active border of their lesion. Cutaneous biopsies of the active border of the lesion were cultivated in BSK-H medium (Sigma) and analysed in vitro by PCR after 8 weeks of culture, using flagellin consensus sequences which are present in all species of Borrelia burgdorferi sensu lato group as primers. Species-specific oligotyping was used for species identification. RESULTS: Among the 18 patients biopsied, 7 had evidence of borrelia infection revealed by culture and/or PCR. Borrelia afzelii was detected in 4 patients and Borrelia garinii in three. CONCLUSION: These preliminary results appear to confirm that Borrelia afzelii and Borrelia garinii are the predominant borrelial species in EM lesions in our geographic area, as in other European countries.

[Rhabdomyolysis induced by pentamidine (Pentacarinat) during treatment of cutaneous leishmaniasis: 2 cases].

INTRODUCTION: We report 2 patients who developed pentamidine-induced rhabdomyolysis during treatment of leishmaniasis. This potentially harmful side effect of pentamidine has only been reported exceptionally until now. CASE REPORTS: In January 2001, we treated 2 patients, aged 31 and 38 years, with 600 mg pentamidine administered intramuscularly twice in 48 hours. The two patients developed rhabdomyolysis with elevated CPK (respectively 30-70-x normal) and myoglobinemia (respectively 20-28-x normal) levels. Outcome was good under hyperhydratation and alkaline diuresis. DISCUSSION: This underestimated side effect of pentamidine treatment is not mentioned in recent articles on the topic. In case of such treatment however, these biological parameters should be monitored in order to establish the real frequency of this side-effect.

[Symetric lipomatosis of the hands].

INTRODUCTION: We report a case of symmetric lipomatosis in an unusual palmary topography. CASE REPORT: A 56 year-old woman was referred for evaluation of scleroderma. The diagnosis was made 10 years earlier because of acrosclerosis of the distal phalanges of both hands. The disease began 2 months after administration of systemic steroids for severe asthma. Since then, she was followed up for her scleroderma every 2 years without any evidence of systematization of the disease. On examination, the first phalanges appeared protruding and podgy on the palms of both hands. On palpation, the consistence was suggestive of lipomas. Similar nodules were present on the back of both hands at the proximal part of the interdigital spaces. Tomodensitometry confirmed the lipomatous nature of nodules. DISCUSSION: This patient presented with a symmetric lipomatosis of a very unusual distal localization on both hands. This unusual aspect mimicked acrosclerosis. In this case report, chronology suggests that systemic steroids might have induced this lipohypertrophy.

Disease expression of Lyme borreliosis in northeastern France.

Since very little is known about the clinical expression of Lyme borreliosis in Western Europe, a 3-year prospective study was conducted that included all patients seen for suspected Lyme borreliosis at the Strasbourg University Hospital in northeastern France. The diagnosis of Lyme borreliosis was made on the basis of the presence of erythema migrans or on the basis of another suggestive clinical manifestation and laboratory confirmation. A total of 132 patients, 70 women and 62 men, mean age 54 years, had Lyme borreliosis according to these criteria. Within this study group, 77% of the patients were regularly exposed to tick bites and 64% could remember one. Erythema migrans, the most frequent clinical manifestation, occurred in 60% of the patients and was the only sign of Lyme borreliosis in 40%. Lymphocytoma and acrodermatitis chronica atrophicans were rare (1 and 3 patients, respectively). Nervous system involvement (mainly radiculoneuropathy), the second most common clinical manifestation, was found in 40% of the patients and was the only sign of Lyme borreliosis in 22%. Musculoskeletal involvement was present in 26% of the patients and was an isolated finding in 14%. During the study period, no patient was diagnosed with Lyme carditis. There was serological evidence of Lyme borreliosis in 75% of the cases and direct evidence of borrelial infection in 10 (7.5%). The results show that the clinical expression of Lyme borreliosis in northeastern France is similar to that in other European countries but different from that in North America.

CD1a molecules traffic through the early recycling endosomal pathway in human Langerhans cells.

In this work, we studied the localization and traffic of CD1a molecules in human epidermal Langerhans cells and the ability of these cells to stimulate CD1a-restricted T cell clones. We found that CD1a was spontaneously internalized into freshly isolated Langerhans cells, where it was rapidly distributed to the early/sorting endosomes and then to the early/recycling endosomes. In the latter compartments, CD1a colocalized with Rab11, a small GTPase known to be involved in the recycling of transmembrane proteins from early endosomes to the cell surface. In the steady state, intracellular CD1a was mainly located in Rab11+ recycling endosomal compartments. When endocytosis was blocked, intracellular CD1a moved rapidly from the early/recycling endosomes to the cell surface where it accumulated. The resultant increase in the cell surface expression of CD1a enhanced the capacity of Langerhans cells to stimulate a CD1a-restricted T cell clone. These findings are consistent with a dynamic exchange of CD1a between recycling compartments and the plasma membrane and suggest that the antigen-presenting function of CD1a depends on its traffic through the early/recycling endosomal pathway.

The Schnitzler syndrome. Four new cases and review of the literature.

The Schnitzler syndrome is characterized by a chronic urticarial eruption with a monoclonal IgM gammopathy. The other signs of the syndrome include intermittent elevated fever, joint and/or bone pain with radiologic evidence of osteosclerosis, palpable lymph nodes, enlarged liver and/or spleen, elevated erythrocyte sedimentation rate, and leukocytosis. The mean delay to diagnosis is more than 5 years, and this syndrome is of concern to internists and many medical specialists. Patients with this syndrome are often initially considered to have lymphoma or adult-onset Still disease, which are the main differential diagnoses. However, hypocomplementic urticarial vasculitis, systemic lupus erythematosus, cryoglobulinemia, acquired C1 inhibitor deficiency, hyper IgD syndrome, chronic infantile neurologic cutaneous and articular (CINCA) syndrome, and Muckle-Wells syndrome should also be excluded, because diagnosis relies on a combination of clinical and biologic signs and there is no specific marker of the disease. The disease pursues a chronic course, and no remissions have yet been reported. Disabling skin rash, fever, and musculoskeletal involvement are the most frequent complications. Severe anemia of chronic disease is another serious complication. The most harmful complication, however, is evolution to an authentic lymphoplasmacytic malignancy, which occurs in at least 15% of patients. This hematologic transformation can occur more than 20 years after the first signs of the disease, thus patients deserve long-term follow-up. Treatment is symptomatic and unsatisfactory. The skin rash is unresponsive to treatment, and nonsteroidal antiinflammatory drugs, antihistamines, dapsone, colchicine, and psoralens and ultraviolet A (PUVA) therapy give inconstant results. Fever, arthralgia, and bone pain often respond to nonsteroidal antiinflammatory drugs. In some patients, these symptoms and/or the presence of severe inflammatory anemia require steroids and/or immunosuppressive treatment, which ameliorate inflammatory symptoms but do not change the course of the skin rash.

[Does subcutaneous cellular tissue exist?].

BACKGROUND: The definition of the "subcutaneous cellular tissue" is still debated. METHODS: In order to establish the localisation and composition of this tissue, or, merely its existence, we interviewed French dermatologists and conducted a bibliographic study on the historical definitions of the so-called "subcutaneous cellular tissue". A questionnaire was sent to French professors of dermatology to assess their definition of the "subcutaneous cellular tissue". They were also asked to make a simple cartoon showing the anatomy of the skin and "subcutaneous cellular tissue". RESULTS: We obtained 37 answers which could be classified in three main categories: 1) "subcutaneous cellular tissue" and hypodermis are synonymous, 2) "subcutaneous cellular tissue" is an autonomous tissue which separates the hypodermis from the tissues below and 3) "subcutaneous cellular tissue" designates all structures located below the hypodermis. In an historic perspective, the "cellular system" was a macroscopic concept described in the eighteenth century as whitish fibrils delimitating "cells". It was renamed loose connective tissue in the twentieth century and thus "cellular" became obsolete. The definition of skin, and of "subcutaneous cellular tissue" in particular, has greatly changed over time. In the eighteenth century, only epidermis and dermis were considered as belonging to the skin, although some included the tela subcutanea. In the twentieth century, the "subcutaneous cellular tissue" is considered either as a part of the hypodermis, or as the hypodermis itself or as a tissue located between the hypodermis and the fascia. DISCUSSION: The difficulty in defining "subcutaneous cellular tissue" is the result of a French semantic problem. The "cellular tissue" became loose connective tissue. For French dermatologists, the skin is composed of epidermis, dermis and hypodermis and the hypodermis can therefore not be subcutaneous. In order to check whether an autonomous tissue could be evidenced under the skin, we conducted an histologic study, which is presented in a second article.

[Blaschko-linear dermatitis in adulthood (Grosshans-Marot disease) with antinuclear antibodies].

E. Grosshans and L. Marot first described blaschkitis in 1990 as a linear inflammatory dermatitis following lines of Blaschko in an adult patient. We report another case which occurred in a 38-year-old woman who developed an extensive, linear, erythematosquamous dermatitis involving the face, all limbs and the trunk. The patient's serum tested positive for antinuclear antibodies at a dilution of 1:640. The lesions regressed spontaneously within 4 weeks. Blaschkitis is a distinct entity which corresponds neither to a known inflammatory dermatitis in the lines of Blaschko nor to an hamartoma nor to an X-linked disease. Cutaneous antigenic mosaicism, the expression of which might be induced by a viral infection, could trigger this localized inflammatory T-cell response. This hypothesis relates blaschkitis to other cutaneous autoimmune diseases, as does the presence of antinuclear antibodies. We therefore suggest renaming this type of inflammatory dermatitis Grosshans-Marot disease in honour to the dermatologists who first described the entity.

Schnitzler syndrome: heterogeneous immunopathological findings involving IgM-skin interactions.

The Schnitzler syndrome is the association of chronic urticaria, intermittent fever, osteosclerotic bone lesions and a monoclonal IgM gammopathy. It is not yet firmly established whether the monoclonal immunoglobulin component plays a part in the pathophysiology of the urticarial lesions. Immunoblotting on epidermal and dermal human skin extracts as well as immunoelectron microscopic (IEM) studies on Lowicryl K4M-embedded skin sections were performed in three patients with the Schnitzler syndrome. Western blotting on epidermal extracts showed the presence of IgM-kappa antiskin autoantibodies in two patients. These antibodies displayed the same isotype as the monoclonal components and recognized a 280-290-kDa antigen in one patient and a 200-kDa antigen in the other patient. IEM studies showed sparse IgM deposits in the epidermis, around the keratinocytes, near the desmosomes in one patient and dense deposits below the lamina densa, in the region of the anchoring fibrils, in another patient. Antiskin IgM autoantibodies of the same isotype as their monoclonal gammopathies can be present in the serum of some patients with the Schnitzler syndrome. These IgM antibodies seem to deposit in vivo in the epidermis and at the dermal-epidermal junction, in the region of the anchoring fibrils. These findings suggest that the monoclonal gammopathy plays a part in the pathophysiology of the skin rash. They also suggest patient heterogeneity both in the skin antigens that are recognized as well as in their localization.

Direct molecular typing of Borrelia burgdorferi sensu lato species in synovial samples from patients with lyme arthritis.

Since Lyme arthritis was first described in the United States, it has now been reported in many countries of Europe. However, very few strains of the causative bacterium, Borrelia burgdorferi, have been isolated from synovial samples. For this reason, different molecular direct typing methods were developed recently to assess which species could be involved in Lyme arthritis in Europe. We developed a simple oligonucleotide typing method with PCR fragments from the flagellin gene of B. burgdorferi sensu lato, which is able to differentiate seven different Borrelia species. Among 10 consecutive PCR-positive patients with Lyme arthritis from the northeastern France, two species were identified in synovial samples: B. burgdorferi sensu stricto in 9 cases and B. garinii in 1 case. Conversely, all B. burgdorferi sensu lato species detected in 10 consecutive PCR-positive biopsies from a second set of patients with erythema migrans from the same geographical area were identified as either B. afzelii or B. garinii (P < 0.001). These results indicate that B. burgdorferi sensu stricto is the principal but not the only Borrelia species involved in Lyme arthritis in northeastern France.

[Cutaneous lymphoma manifesting as pigmented, purpuric capillaries].

INTRODUCTION: A few cases of patients with both purpuric pigmented dermatitis and cutaneous lymphoma have been reported. The aim of this study was to evaluate the prognosis of purpuric pigmented dermatitis. MATERIAL AND METHODS: This is a monocentric retrospective study at the dermatology department of the university hospital of Strasbourg. The records of all patients hospitalized for purpuric pigmented dermatitis between 1967 and 1997 have been reviewed. RESULTS: Eight women and 9 men aged between 17 and 84 years were hospitalized for purpuric pigmented dermatitis during the reference period. Except for one patient, all had had a cutaneous biopsy showing the typical features of purpuric pigmented dermatitis. On the basis of clinical signs and course, one patient was thought to have contact dermatitis and three patients were thought to have a purpuric pigmented dermatitis-like drug eruption (meprobannate, pefloxacine and lorazepam or aspirin). The mean follow-up was one year. During follow-up, two patients developed cutaneous T-cell lymphoma after two and four years respectively and one patient developed Hodgkin's disease with skin and lymph node involvement. Another patient who suffered from purpuric pigmented dermatitis for four years had a monoclonal T cell population within the dermal infiltrate. Two patients died of their lymphoma. DISCUSSION: This study shows that purpuric pigmented dermatitis can be associated to or evolve into lymphoproliferative disease. This course should be suspected when purpuric pigmented dermatitis is extensive, long-lasting (> 1 year), has a reticular arrangement and negative patch-testing. In this situation, a long-term follow-up and treatments indicated in the early patch stage of mycosis fungoides (PUVA therapy, chlormethine) seem adequate.

Eccrine porocarcinoma, tricholemmal carcinoma and multiple squamous cell carcinomas in a single patient.

A 75-year old woman without remarkable medical history presented with a large eccrine porocarcinoma of the trabelucar type located on her leg. This tumor was associated with two invasive squamous cell carcinomas of the legs, two Bowen's diseases of her thigh and arm and multiple actinic keratoses of the face. Despite major surgery, local recurrence of the porocarcinoma was observed 6 months later. During the 3-year follow-up after a second surgical intervention, this lesion did not reccur, but the patient developed a rapidly enlarging ulcerated tumor of the forehead which proved to be tricholemmal carcinoma. Although no carcinogenetic factor or familial history of multiple neoplasms could be evidenced, the occurrence of multiple tumors of various histogenesis over a 1 year period of time is unlikely to be fortuitous. Such an association of rare adnexal neoplasms has not yet been described.
