1/112. Anti-epiligrin cicatricial pemphigoid: a case associated with gastric carcinoma and features resembling epidermolysis bullosa acquisita.A 48-year-old woman with anti-epiligrin cicatricial pemphigoid (CP) who showed clinical features resembling epidermolysis bullosa acquisita was found to have adenocarcinoma of the stomach. Histological examination of lesional skin demonstrated a subepidermal blister. Direct immunofluorescence microscopy of perilesional skin revealed linear deposits of IgG and C3 at the basement membrane zone. The patient's serum contained IgG autoantibodies that bound to the dermal side of 1 mol/L NaCl-split normal human skin as determined by indirect immunofluorescence microscopy, and the lamina lucida as determined by indirect immunoelectron microscopy. The patient's serum immunoprecipitated laminin-5 from extracts and media of biosynthetically radiolabelled human keratinocytes. Immunoblot studies showed that the patient's autoantibodies specifically bound the alpha3 subunit of this laminin isoform. Fragility of the skin and bullous lesions disappeared after total gastrectomy, but soon reappeared possibly in association with metastatic disease in a lymph node. The possibility that anti-epiligrin CP may develop paraneoplastically in some patients is discussed.- - - - - - - - - - ranking = 1keywords = membrane, lamina (Clic here for more details about this article) |
2/112. Anti-epiligrin cicatricial pemphigoid with antibodies against the gamma2 subunit of laminin 5.BACKGROUND: Cicatricial pemphigoid (CP) is a scarring subepithelial mucocutaneous blistering disease characterized by anti-basement membrane zone autoantibodies. Anti-epiligrin CP is an uncommon variant that has been recently characterized. Severe laryngeal involvement is infrequently observed in all forms of CP and has been documented in only 2 patients with anti-epiligrin CP. OBSERVATIONS: We report a case of CP exhibiting extensive laryngeal and ocular involvement. Histological, immunofluorescence, and immunoprecipitation studies confirmed the diagnosis of anti-epiligrin CP. immunoblotting studies demonstrated the presence of antibodies against the alpha3 and the gamma2 subunit of laminin 5. CONCLUSION: This article expands the diversity of the clinical and immunopathologic features of this newly characterized variant of CP.- - - - - - - - - - ranking = 0.92073522426658keywords = membrane (Clic here for more details about this article) |
3/112. Anti-epiligrin cicatricial pemphigoid with IgG autoantibodies to the beta and gamma subunits of laminin 5.Anti-epiligrin cicatricial pemphigoid is an autoimmune subepithelial blistering disorder of mucous membranes and skin. By immunoblot analyses, sera of most patients with antiepiligrin cicatricial pemphigoid have been shown to react specifically with the alpha3 chain of laminin 5. We describe the first patient with anti-epiligrin cicatricial pemphigoid in whom circulating IgG autoantibodies directed against the beta3 and gamma2-chains of laminin 5 were detected. Treatment with oral prednisolone was beneficial in controlling the disease.- - - - - - - - - - ranking = 410.47556123675keywords = mucous membrane, membrane (Clic here for more details about this article) |
4/112. Childhood vulval pemphigoid: a clinical and immunopathological study of five patients.We describe five girls with vulval pemphigoid: two had bullous pemphigoid confined to the vulva and three had cicatricial pemphigoid. They demonstrate a spectrum of severity from localized disease to extensive vulval scarring necessitating long-term immunosuppressive therapy and surgical correction. The age at onset of their disease ranged between 6 and 13 years. All presented with vulval discomfort and erosions. Three had oral lesions, two perianal and one eye and cutaneous involvement. Two girls with only vulval lesions and one with vulval and oral lesions responded well to topical steroids. In two, systemic treatment with prednisolone and dapsone or azathioprine was required. The diagnosis was made on the basis of histology and immunofluorescence (IF). All had positive direct IF with IgG and C3. Indirect IF demonstrated circulating IgG binding to the basement membrane zone in four, with dermal or epidermal binding on salt-split skin substrate. immunoblotting revealed antibodies to the BP230 and BP180 antigens. Immunoelectron microscopy in the child with dermal binding IgG and BP180 and BP230 on immunoblotting showed labelling at the lamina densa-lamina lucida interface adjacent to hemidesmosomes.- - - - - - - - - - ranking = 1.0792647757334keywords = membrane, lamina (Clic here for more details about this article) |
5/112. Antiepiligrin (laminin 5) cicatricial pemphigoid associated with an underlying gastric carcinoma producing laminin 5.Although bullous pemphigoid and cicatricial pemphigoid are sometimes associated with malignancy, it remains uncertain whether such an association is pathogenetically related or just a coincidence attributable to the advanced age of the patients. We report a 61-year-old patient with antiepiligrin (laminin 5) cicatricial pemphigoid (AeCP) associated with an advanced gastric carcinoma. The gastric carcinoma cells in this patient were shown to produce laminin 5 by immunofluorescence microscopy, and the patient's serum contained autoantibodies directed against laminin 5 on immunoprecipitation. Furthermore, the blistering symptoms and the titre of antibasement membrane zone antibodies coordinately changed with the resection and subsequent relapse of the gastric cancer. These observations suggest that the gastric carcinoma producing laminin 5 may have induced the production of autoantibodies to this laminin, which were pathogenic to the skin and mucous membranes in this patient. This report demonstrates a link between this autoimmune subepithelial blistering disease and malignancy. It is of interest and potential great importance to examine other cases of AeCP for such a potential association.- - - - - - - - - - ranking = 411.39629646102keywords = mucous membrane, membrane (Clic here for more details about this article) |
6/112. epidermolysis bullosa acquisita with combined features of bullous pemphigoid and cicatricial pemphigoid.epidermolysis bullosa acquisita (EBA) is an acquired subepidermal blistering disease associated with autoantibodies against type VII collagen. The classical or mechanobullous form of EBA is characterized by skin fragility, trauma-induced blisters and erosions with mild mucous membrane involvement and healing with scars. Furthermore, bullous-pemphigoid-like and cicatricial pemphigoid-like features have been described. We report a patient who developed a bullous skin disease with upper airway obstruction requiring tracheotomy. The diagnosis of EBA was established by immunoblot, showing a band at 290 kD (collagen VII), and NaCl-split skin immunofluorescence (IgG deposition at the floor of the split). This case presented with clinical features of both bullous pemphigoid and cicatricial pemphigoid which to our knowledge is the first report of such a combination in EBA. The patient also presented tracheal involvement that has never been described either.- - - - - - - - - - ranking = 410.47556123675keywords = mucous membrane, membrane (Clic here for more details about this article) |
7/112. Paraneoplastic cicatricial pemphigoid.We report a 39-year-old woman with antiepiligrin cicatricial pemphigoid (CP) in association with non-small cell carcinoma of the lung. At presentation, mucosal lesions showed minimal response to combined systemic immunosuppressive agents. Following the diagnosis of non-small cell lung carcinoma and subsequent treatment with gemcitabine (a second-line chemotherapeutic agent), a significant reduction in both tumour mass and mucosal blistering was observed. Metastatic disease was subsequently associated with recurrent oral erosions. We believe this patient represents the first reported case of paraneoplastic CP.- - - - - - - - - - ranking = 0.14041956571807keywords = mucosa (Clic here for more details about this article) |
8/112. Linear IgA dermatosis mimicking ocular cicatricial pemphigoid.PURPOSE: To describe an unusual case of cicatrizing conjunctivitis. methods AND RESULTS: A 59 year old male presented in July 1997 with a complaint of intermittent redness and discharge of the right eye. Medical history was significant for a buccal mucosal lesion biopsy taken two years earlier that revealed subepidermal fibrosis. Conjunctival biopsy, performed to rule out ocular cicatricial pemphigoid, yielded a diagnosis of linear IgA dermatosis, an unusual diagnosis not often considered by ophthalmologists. CONCLUSIONS: The diagnosis of cicatrizing conjunctivitis is often overlooked. Its importance as it pertains to the life threatening disease of ocular cicatricial pemphigoid is clear.- - - - - - - - - - ranking = 0.070209782859036keywords = mucosa (Clic here for more details about this article) |
9/112. Cicatrizing conjunctivitis associated with paraneoplastic lichen planus.PURPOSE: To report two cases of cicatrizing conjunctivitis associated with paraneoplastic lichen planus. methods: case reports. RESULTS: Two patients were examined because of redness and discomfort in both eyes. A 63-year-old woman with follicular, small-cleaved cell lymphoma had cicatrizing conjunctivitis, stomatitis, vulvitis, and skin lesions. A 25-year-old man with malignant thymoma had cicatrizing conjunctivitis, erosive stomatitis, and penile papules. Histopathologic studies of conjunctiva and skin biopsy specimens in the first patient and labial biopsy specimens in the second revealed lichen planus. CONCLUSION: Paraneoplastic lichen planus is a possible cause of cicatrizing conjunctivitis associated with inflammatory skin and mucous membrane disease.- - - - - - - - - - ranking = 410.47556123675keywords = mucous membrane, membrane (Clic here for more details about this article) |
10/112. Cicatricial pemphigoid with an upper airway lesion.Cicatricial pemphigoid is an unusual mucocutaneous disease that is characterized by subepidermal blister formation involving the oral and conjunctival membranes. The oral lesions are expressed as erythema and induration and have rarely been associated with upper airway obstruction. We report the case of a patient with dyspnea and an abnormal flow-volume loop who was found to have subglottic compromise due to cicatricial pemphigoid. Immunosuppressive therapy improved his symptoms and air flow.- - - - - - - - - - ranking = 0.92073522426658keywords = membrane (Clic here for more details about this article) |
