No evidence for a role of human herpesvirus type 8 in sarcoidosis: molecular and serological analysis.

The aim of this study was to analyse the association between human herpesvirus type 8 (HHV8) and sarcoidosis. Using nested polymerase chain reaction (PCR), we tested the presence of HHV8 DNA sequences in 13 skin specimens and peripheral blood mononuclear cells from eight patients suffering from sarcoidosis. We also looked for the presence of HHV8 antibodies in the sera of 28 patients with sarcoidosis using three techniques: two indirect immunofluorescence assays and an enzyme-linked immunosorbent assay with recombinant capsid protein fragment encoded by open-reading frame 65. HHV8 PCR analysis was negative while HHV8 serological studies showed an overall prevalence of 18% among patients suffering from sarcoidosis: 43% in patients from sub-Saharan Africa, 17% in patients from Northern Africa, 12.5% in patients from the French West Indies and 0% in French patients. In conclusion, our results do not indicate an association between HHV8 and sarcoidosis but reflect the seroepidemiology of this virus in different geographical regions.

[Adult T-cell lymphoma associated with HTLV-1: a familial form].

BACKGROUND: Adult T-cell leukemia-lymphoma (ATL) can occur in siblings infected with HTLV-1. CASE REPORTS: Two Caribbean siblings developed ATL a few years apart. One case has been reported previously. Both individuals had peripheral lymph node T-cell lymphoma and a few atypical lymphocytes on blood smear. Lymphocytosis, bone marrow biopsy, abdominal computed tomographic scanning, and chest radiography were normal. Clonal rearrangement of T-cell receptor was present in skin lesions for both patients and in the blood for one. HTLV-1 serology was positive. Clonal integration of HTLV-1 provirus was demonstrated in skin lesions in one patient and in blood lymphocytes in the other. Chemotherapy, then interferon alpha, were unsuccessful in the first patient. Topical metchloretamine was partially effective for the second patient. DISCUSSION: ATL in siblings is explained by mother-to-child transmission of HTLV-1 infection during breastfeeding.

Atypical Lyme borreliosis in an HIV-infected man.

We report the fourth case of Lyme borreliosis in a man infected with human immunodeficiency virus (HIV). The erythema chronicum migrans was persistent, overlapping with meningoradiculitis. Repeated immunofluorescence tests for Borrelia burgdorferi sensu lato remained negative in both sera and cerebrospinal fluid (CSF), the enzyme-linked immunosorbent assay was weakly positive in serum and CSF and a Western blot was positive. The skin infiltrate was composed mostly of T lymphocytes with a CD4/CD8 ratio of 0.5. The course of the disease was favourable after treatment with intravenous ceftriaxone. Further studies are necessary to evaluate whether HIV infection influences, as does syphilis, the course and response to treatment of Lyme borreliosis. Serological tests are insufficiently sensitive and the Western blot assay is necessary to confirm Lyme disease in HIV-positive patients.

Melanoderma revealing primary antiphospholipid syndrome.

Acute adrenal insufficiency is a rare complication of the primary antiphospholipid syndrome. We report a case of melanoderma of rapid onset revealing an addisonian crisis associated with primary antiphospholipid syndrome, which was associated with life-threatening hypercalcemia. Melanoderma does not belong to the clinical presentation of acute adrenal insufficiency. Its very rapid onset in our patient is probably due to her very high level of serum ACTH, in relation with her recent abortion.

Ivermectin-responsive crusted scabies in HTLV1 carrier.

We report a case of HTLV1 infection revealed by crusted scabies and widespread dermatophytosis in an African woman. HTLV1 infection was not complicated by adult T cell leukemia or myelopathy. Crusted scabies is a marker of HTLV1 infection. The importance of oral ivermectin therapy in crusted scabies is emphasized.

[Scleroderma-like patch on the thigh in infants after vitamin K injection at birth: six observations].

INTRODUCTION: Texier's disease or pseudosclerodermatous reaction after intramuscular injection of vitamin K1 is well known in adults although only 1 report of a case in a newborn was found in the literature. We report 6 cases. CASE REPORTS: Six infants (4 boys, 2 girls) developed "peau d'orange" skin lesions after the age of 6 months which was localized in the lower third of the medial aspect of the thigh. Initial rapid locoregional extension was followed by stabilization and then regression. In all 6 cases, histology showed lesions of the fascia and/or the deep hypoderma associated with variable mononuclear inflammatory infiltration and hyalin fibrosis. When performed, immunological studies (complement fixation, search for autoantibodies) were always negative or normal. No visceral involvement was found. DISCUSSION: A pseudosclerodermatous lesion of the lower third of the thigh occurred in 6 infants at the site of an intramuscular injection of vitamin K1 administered at birth. The history, clinical manifestations, histology and outcome of these cases are compatible with the diagnosis of Texier's disease. We discuss the role of the solvent in the Roche vitamin K1 injection. The pathogenesis of this side effect remains unknown. CONCLUSION: Texier's disease in infants after injection of vitamin K1 at birth is a stereotypic dermatosis. Diagnosis is based on history and clinical presentation. The causal effect of injectable vitamin K1 should be entertained whenever pseudosclerodermatous lesions are observed in a young child.

[Dermatoses of the nipple and the areola].

Dermatoses of the nipple and areola are rare. The commonest dermatosis is Paget's disease, which presents in the form of a well demarcated erythematous area, sometimes erosive, oozing or hyperkeratotic. Histological examination reveals an intraepidermal proliferation of large clear cells, either isolated or grouped in clumps, predominantly in the suprabasal layers. Immunohistochemistry shows that these cells express low molecular weight cytokeratins and the epithelial membrane antigen, fairly frequently carcinoembryonic antigen. In 96% of cases, Paget's disease is associated with underlying breast carcinoma, either in situ or invasive. Erosive adenomatosis presents in the form of an erosion of the nipple, which is sometimes increased in size. Histologically, it consists of a benign tumour which may ulcerate the epidermis, composed of tubes and papillae lined by a double layer of epithelial and myoepithelial cells. The syringomatous tumour is exceptional. In places, it forms rudimentary sweat ducts and is considered to have an intermediate malignancy; its resection must be complete. Other tumours may also be observed in this site: leiomyoma, leiomyosarcoma, benign cutaneous lymphocytoma, basal cell carcinoma, naevoid areolar hyperkeratosis. They are exceptional except areolar neurofibromas in case of neurofibromatosis. Infectious dermatoses (viral warts, molluscum contagiosum, scabies) are accompanied by lesions in other sites. They same applied to the majority of inflammatory dermatoses such as eczema or Fox-Fordyce disease. Supernumerary nipples are situated on a line extending from the anterior part of the axillary crease to the medial part of the inguinal crease.

[Intra-epidermal pustulosis in a child. Demonstration of a target antigen similar to foliaceus pemphigus antigen].

INTRODUCTION: Intraepidermal IgA pustulosis is a vesiculopustular dermatosis defined by pemphigus type intercellular deposit exclusively of IgA. It is a member of the pemphigus group and may be related to neurtrophilic dermatoses. CASE REPORT: A child had vesiculopustular lesions of the limbs since the age of 11 years. Biopsy showed the subcorneal intraepidermal nature of the pustules and exclusive IgA deposit throughout the epiderma. Indirect immunofluorescence and protein immunoelectrophoreses were negative. Immunotransfer to beef tongue extract evidenced a 150-160 kDa band corresponding to IgA and IgG desmoglein. Treatment with general corticosteroids followed by pristinamycin was successful. DISCUSSION: This is the first case report showing evidence of antiepidermal antibodies directed against the superficial pemphigus antigen.

[Acquired localized epidermolysis bullosa. A case with scalp involvement and immunoelectron microscopic study].

The case of a 59-year old man who had a clinical Brunsting-Perry pemphigoid localized to the scalp is described. Direct immunoelectron microscopy demonstrated IgG and C3 immune deposits in the anchoring fibril zone, as in epidermolysis bullosa acquisita. No circulating antibodies were detected by Western immunoblotting on epidermal and dermal extracts. These findings show that Brunsting-Perry pemphigoid is not an immunological entity and that it widens the clinical spectrum of epidermolysis bullosa acquisita.
