结节性类天疱疮

结节性类天疱疮是大疱性类天疱疮的罕见型,多见于老年患者,主要临床表现是结节、水疱,病理、直接免疫荧光、间接免疫荧光显示大疱性类天疱疮特征。治疗上需系统应用皮质类固醇激素,有时需合并使用免疫抑制剂。免疫印迹试验发现多数PN患者血清与230kD的表皮抗原相结合。

Unusual variants of pemphigoid: from pruritus to pemphigoid nodularis

We report three patients with pemphigoid nodularis. Patients were females aged 76, 71 and 50 years, and all had features of bullous pemphigoid together with prurigo-like lesions at some stage of their illness. In two cases, nodular lesions preceded the onset of blistering by some months. Blisters arose on normal skin and in one patients also at sites of prurigo lesions. Routine histology of bullous lesions revealed the presence of subepidermal blisters. Electron microscopy performed in two cases confirmed the level of split to be through the lamina lucida. Direct immunofluorescence in all cases was positive, with linear basement membrane zone deposition of IgG and C3. Circulating IgG anti-basement membrane antibody was also detected in all patients, and in two, immunoblotting revealed a single antigen of 220 kD.     

A case of epidermolysis bullosa acquisita with unusual clinical features

A 30‐year‐old woman developed epidermolysis bullosa acquisita (EBA) with unusual clinical features. Initially, only prurigo‐like nodules were seen, which lasted for > 2 years and then blisters appeared. Eruptions resembling the rash in systemic lupus erythematosus were also seen on the face. Histopathological examination of a biopsy specimen revealed subepidermal blisters containing eosinophils and neutrophils. Direct immunofluorescence examination, indirect immunofluorescence examination using skin split with 1 mol/L sodium chloride, and immunoblotting analysis using extracts of normal human dermis gave results compatible with EBA. This case shows that EBA can present with nodular lesions as seen in pemphigoid nodularis or epidermolysis bullosa pruriginosa.

Demonstration by S-100 protein staining of increased numbers of nerves in the papillary dermis of patients with prurigo nodularis.

BACKGROUND: We hypothesized that hyperplasia of papillary dermal nerves was a constant feature of prurigo nodularis. OBJECTIVE: We tested this hypothesis by examining sections from 25 cases of prurigo nodularis, 25 cases of skin lesions characterized by epidermal hyperplasia without clinical pruritus, and 22 cases of clinically pruritic dermatoses with variable degrees of epidermal response for the presence of papillary dermal nerves. METHODS: We used a standard immunohistochemical assay with an antibody to S-100 protein as a means of identification of nerves. RESULTS: In 24 of 25 cases of prurigo nodularis, papillary dermal nerves were identified by immunostaining. Cutaneous nerves were present in 1 of 22 cases of epidermal hyperplasia with pruritus and were absent in the papillary dermis in nonpruritic cases. CONCLUSION: We conclude that hypertrophy of cutaneous papillary dermal nerves is a relatively constant feature of prurigo nodularis. The presence of papillary dermal nerves suggests a neurocutaneous component in the pathogenesis of prurigo nodularis.     

Pemphigoid nodularis: a case report

Several variants of bullous pemphigoid have been reported including pemphigoid nodularis. Patients with pemphigoid nodularis have clinical features of prurigo nodularis in combination with clinical or immunologic characteristics of bullous pemphigoid. We report the case of a 71-year-old woman with pemphigoid nodularis. The diagnosis was suspected clinically and established by positive indirect immunofluorescence (IIF) findings characteristic of pemphigoid. Results of direct immunofluorescence (DIF) testing were negative, which emphasizes the importance of conducting both DIF and IIF when pemphigoid nodularis is suspected.     

Combination therapy of fexofenadine and montelukast is effective in prurigo nodularis and pemphigoid nodularis

In this study, we report on the efficacy of combination therapy of second‐generation antihistamine antagonist, fexofenadine hydrochloride, and leukotriene receptor inhibitor, montelukast sodium, for the treatment of 15 prurigo nodularis or pemphigoid nodularis patients, in whom conventional therapy was ineffective. All patients received 10 mg montelukast once a day and 240 mg fexofenadine twice a day for 4 weeks in addition to other medications they had been taking. We assessed the manifestations of the lesions and itching intensity before and after the therapy, and we evaluated each patient as (i) markedly improved, (ii) improved, (iii) slightly improved, (iv) no change, (v) worse. Two patients (13.3%) were evaluated as markedly improved, and the lesions of one patient completely disappeared. Three patients (20.0%) were evaluated as improved, and six patients (40.0%) as slightly improved. Thus, 11 of 15 cases (73.3%) improved by combination therapy of fexofenadine and montelukast, in which nine cases (75.0%) of prurigo nodularis and two cases (66.7%) of pemphigoid nodularis were involved. No patients revealed any side effects. This study revealed that combination therapy of fexofenadine and montelukast was effective for some patients with conventional therapy‐resistant prurigo nodularis and pemphigoid nodularis.     

Pemphigoid nodularis: a report of three cases and review of the literature

Many variants of bullous pemphigoid have been reported, some of which are clinically very atypical. One of the rarest variants is pemphigoid nodularis. We report three patients with this distinct entity. In all three cases patients initially presented with prurigo-like lesions and in one case nodular lesions preceded the onset of blistering by many months. Direct immunofluorescence was positive in all cases, with linear basement membrane zone deposition of IgG and C3. Circulating IgG antibasement membrane antibody was detected in two cases. and in these two patients on salt-split immunofluorescence the antibodies bound to the roof of the bullae.     

Prurigo papules with blisters

A 73 year old woman developed prurigo papules which were complicated by blisters. Skin biopsy and immunofluorescence revealed bullous pemphigoid. The diagnosis of pemphigoid nodularis was made.
