1/109. Unilateral linear lichen planus with mucous membrane involvement.Linear lichen planus is a rare distinctive variant of lichen planus (LP) characterized by a pruritic eruption of lichenoid, violaceous papules in a linear distribution that sometimes assume a Blaschko line pattern. We describe a 33-year-old woman who presented with a 4-month history of a slightly pruritic unilateral linear array of papular lesions on the left side of her neck that were clinically and histologically consistent with linear LP. Two months after the onset of her skin disease she developed typical lesions with a lacy white pattern on the left lateral aspect of her tongue and the left buccal mucosa with a striking predominance for the left side. Clinically the lesions on the patient's neck were similar to lichen striatus or lichenoid epidermal naevus, a variant of linear verrucous epidermal naevus. However, the histological features and the fact that later in the course of her disease the patient developed typical LP of the oral mucosa suggest that this patient has the rare condition of linear LP with unilateral restriction.- - - - - - - - - - ranking = 1keywords = mucous membrane, mucosa, membrane (Clic here for more details about this article) |
2/109. Erosive mucosal lichen planus: response to topical treatment with tacrolimus.Erosive mucosal lichen planus is a painful and disabling inflammatory skin disease that is highly resistant to topical treatment. We report on six patients with severe recalcitrant erosive mucosal lichen planus who benefited from topical application of tacrolimus ointment. After 4 weeks of treatment, complete resolution was observed in three cases, and substantial improvement was achieved in the other three patients. In these cases, prolonged treatment resulted either in further improvement or in complete healing. All patients reported rapid relief from pain and burning. No severe side-effects were observed.- - - - - - - - - - ranking = 0.085690080439277keywords = mucosa (Clic here for more details about this article) |
3/109. Demonstration of antibody to 230 kDa bullous pemphigoid antigen in lichen planus-like keratosis.We describe a 67-year-old man with lichen planus-like keratosis associated with anti-230 kDa bullous pemphigoid antigen (BPAG1) autoantibody. The patient had noticed solitary dark brown macule more than 6 years previously on his left chest. Histological findings showed hypergranulosis, irregular acanthosis, liquefaction degeneration of basal cells, band-like infiltration of lymphocytes at the subepidermal portion, and a cleft at the basement membrane zone (BMZ), resulting in the formation of subepidermal blisters. Direct immunofluorescence findings of perilesional skin showed a linear deposition of IgG at BMZ. On indirect immunofluorescent study using normal human skin, circulating IgG autoantibody to BMZ was present in the patient's serum at a titer of 1:80. The antigen located on the epidermal site of normal skin split by 1M NaCl was reacted with the patient's serum. Immunoblot analysis using epidermal extracts demonstrated the presence of IgG antibody directed to BPAG1 in the patient's serum. These observations suggest that the presence of an antibody to BPAG1 could be caused by the damage of basal cells following lichen planus-like keratosis.- - - - - - - - - - ranking = 0.0011152508801716keywords = membrane (Clic here for more details about this article) |
4/109. stevens-johnson syndrome. Description of an unusual clinical case due to glucocorticoid therapy for oral lichen planus.erythema multiforme (EM) is an acute inflammatory disease with an autoimmune pathogenesis clinically expressing in a wide variety of mucocutaneous illnesses. It is usually described in a minor form (Von Hebra) characterized by classical cutaneous lesions, and in major form (Stevens-Johnson), involving mucosal damage, while a clinical type restricted to the oral mucosa is described in oral pathology. A considerable number of factors of different nature have been reported as etiologic agents of EM, but most of them are not well documented; however, a certain relationship with EM is recognized for different classes of systemic drugs. This paper describes a case of stevens-johnson syndrome with initial oral involvement, in which the precipitating factor was due to the administration of systemic glucocorticoids, prescribed for the therapeutic treatment of an erosive form of oral lichen planus.- - - - - - - - - - ranking = 0.028563360146426keywords = mucosa (Clic here for more details about this article) |
5/109. IgG autoantibodies from a lichen planus pemphigoides patient recognize the NC16A domain of the bullous pemphigoid antigen 180.lichen planus pemphigoides (LPP) most likely encompasses a heterogeneous group of subepidermal autoimmune blistering disorders occurring in association with lichen planus. We describe the case of a 49-year-old patient with features characteristic of LPP. Direct immunofluorescence microscopy studies demonstrated linear deposits of C3 along the cutaneous basement membrane, while circulating IgG autoantibodies directed against the epidermal side of skin separated by 1 M NaCl were detected. The patient's serum contained IgG autoantibodies immunoblotting a recombinant form of bullous pemphigoid antigen 180 (BP180), but not the COOH-terminus of BP230. By using deletion mutants, it was found that IgG reactivity was restricted to the NC16A domain of BP180, the region harboring the major antigenic sites targeted by IgG autoantibodies from patients with the bullous pemphigoid group of disorders. Our findings provide support to the idea that a subset of patients with LPP have a distinct form of bullous pemphigoid associated with lichen planus.- - - - - - - - - - ranking = 0.0011152508801716keywords = membrane (Clic here for more details about this article) |
6/109. 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 = 0.24285915996339keywords = mucous membrane, membrane (Clic here for more details about this article) |
7/109. Oesophageal lichen planus.We present a case of lichen planus affecting the oesophagus of an 80-year-old woman. Symptomatically, the lesions manifested themselves as dysphagia requiring repeated oesophageal dilatations. The patient was unable to tolerate several conventional treatments and so pulsed methylprednisolone was given with some beneficial short-term effects. Due to potential for malignant change in lichen planus of the mucous membranes it is important to remember this complication and investigate patients with oesophageal symptoms.- - - - - - - - - - ranking = 0.24285915996339keywords = mucous membrane, membrane (Clic here for more details about this article) |
8/109. lichen planus with involvement of all twenty nails and the oral mucous membrane.A 57-year-old man had had deformities of all ten fingernails for one and a half years before presentation and deformities of all ten toenails for the previous six months. The surfaces of the nails were rough, with excessive longitudinal striations. The bases of the nails were slightly hypertrophic, and the tips were atrophic and itchy. A longitudinal nail biopsy including the nail matrix revealed the typical histology of lichen planus. Reticulated pigmentation, maceration, and erosion on the buccal mucous membrane were also discovered. Histological analysis of the buccal mucous membrane revealed lichen planus intermingled with eosinophils. Immunological blood analysis revealed elevated CD4 T cells and CD4/CD8 ratio. He worked as a tinsmith and had dental metal. The metal series patch test revealed positive reactions to chromate and tin. Treatment with systemic steroids was quite effective in treating the nail lesions.- - - - - - - - - - ranking = 1.4571549597804keywords = mucous membrane, membrane (Clic here for more details about this article) |
9/109. lichen planus pemphigoides with circulating autoantibodies against 200 and 180 kDa epidermal antigens.We describe a case of lichen planus pemphigoides with circulating autoantibodies against 200 and 180 kDa epidermal antigens. A 24-year-old man presented pruritic erythematous patches with occasional central blister formation on the face, neck, and trunk and erythematous hyperkeratotic patches on the elbows and feet for 10 months. Histopathological findings of the neck and plantar lesions were consistent with lichen planus. Direct immunofluorescence studies from both lesions showed a linear deposition of IgG and C3 and cytoid bodies along the basement membrane zone. Indirect immunofluorescence studies demonstrated circulating IgG antibodies deposited on the epidermal side of salt-split skin. Immunoblot analysis using epidermal extract showed that the patient's serum reacted with 180 kDa bullous pemphigoid antigen (BPAG2) and a 200 kDa antigen. The cutaneous lesions almost cleared with a low dose of prednisolone and acitretin.- - - - - - - - - - ranking = 0.0011152508801716keywords = membrane (Clic here for more details about this article) |
10/109. PUVA-induced lichen planus pemphigoides.A 72-year-old woman had suffered from parapsoriasis en plaque (large plaque type) controlled by topically applied psoralen ultraviolet A (PUVA) therapy. The parapsoriasis lesions gradually disappeared, but numerous tiny red papules with pruritus appeared over the forearms and lower legs 120 days after starting puva therapy. These papules developed to form violaceous plaques. Histological findings demonstrated the characteristics of lichen planus. Two months later, tense bullae developed on the plaques and on uninvolved skin of the limbs. These were subepidermal, with linear deposits of IgG and C3 along the basement membrane zone (BMZ) in immunofluorescence of peribullous skin, and immunodeposits of type IV collagen along the floor of the bullae. We therefore, diagnosed lichen planus pemphigoides (LPP). Using systemic and topical steroid therapy, the lesions rapidly resolved and there has been no recurrence. This case suggests that the combination of basal cell injuries caused by chronic inflammation and puva therapy could expose BMZ components to autoreactive lymphocytes and induce LPP.- - - - - - - - - - ranking = 0.0011152508801716keywords = membrane (Clic here for more details about this article) |
