Lichen Planus Pemphigoides Presenting Preferentially Over Preexisting Scars: A Rare Instance of Isotopic Phenomenon

An 18-year-old girl presented with multiple itchy hyperpigmented papules and plaques, along with tense blisters over the lower limbs and buttocks for last 3 months. These papules, plaques, and bullae were mostly localized to preexisting scars. The histopathological findings from papule and bulla were consistent with lichen planus (LP) and bullous pemphigoid, respectively. Direct immunofluorescence (DIF) of perilesional skin around bulla showed linear deposition of IgG and C3. Considering clinical, histopathological and DIF findings, diagnosis of LP pemphigoides (LPP) was made. The preferential localization of LPP lesions over preexisting scars was a very interesting finding in our case an extremely rare instance of the isotopic phenomenon.     

Bullous pemphigoid associated with prostate adenocarcinoma

Bullous pemphigoid is a common autoimmune skin disease characterized by the presence of subepidermal blisters. It has been associated with underlying neoplasia in isolated reports. A 78-year-old man with generalized blisters was diagnosed as bullous pemphigoid on clinical, histopathological and direct immunofluorescence grounds. His free and total prostate specific antigen (PSA) levels were high and histopathological examination of a prostate specimen revealed prostate adenocarcinoma. We present this rare case to discuss the possible association between bullous pemphigoid and prostate adenocarcinoma.     

Therapie des Lichen planus pemphigoides durch Acitretin und pulsweise verabreichtes Kortikosteroid

A patient with lichen planus pemphigoides first developed multiple pruritic papules and subsequently, tense blisters on trunk and extremities. Histopathologic examination of a skin biopsy demonstrated both the typical changes of lichen planus and subepidermal blisters as in bullous pemphigoid. Direct immunofluorescence microscopy revealed both cytoid bodies and linear C3 deposits at the dermal-epidermal junction. By indirect immunofluorescence microscopy on 1 M NaCl-split-skin, circulating autoantibodies labeled the epidermal side of the split. Immunoblot analysis showed binding of the antibodies to the cell-derived soluble 120 kD domain of the 180 kD bullous pemphigoid antigen and to a recombinant form of the immunodominant NC16A region of this protein. When treated with pulsed intravenous corticosteroids, the patient continued to develop new papules and blisters, but when oral acitretin was added, the skin lesions cleared. The immunoblot reactivity of the patient's autoantibodies well reflected disease activity, while the indirect immunofluorescence microscopy titers did not.     

Scabies presenting with bullous pemphigoid-like lesions

A wide range of clinical manifestations may be seen in scabies, from classic pruritic papules and burrows to secondary features such as impetigo. Bullus lesions are a less frequent. Twenty cases of scabies presenting with bullae have been reported so far in the medical literature. Differentiating this subtype of scabies from the immunobullous disease bullus pemphigoid is a diagnostic challenge. A 42-year-old man was referred to our dermatology outpatient clinic with 3-month history of severe pruritus and tense blisters affecting mainly the lower trunk, arms and legs. An initial biopsy was suggestive for bullous pemphigoid. Close physical examination revealed small excoriated papules and a few burrows on borders of the hands and wrists. Skin scraping of the lesions on wrists was positive for Sarcoptes scabiei. Another biopsy specimen from a recent blister revealed subepidermal bullae with fibrin and inflammatory cells, particularly eosinophils. Direct immunofluorescence exam was negative. The patient was treated with lindane lotion followed by crotamiton cream with near complete resolution of the lesions. Scabies must be considered in patients presenting with recent onset of unexplained pruritic bullous lesions. Biopsy and immunofluorescence studies together with skin scrapings for Sarcoptes scabiei could help to differentiate these cases from bullous pemphigoid. Antiscabietic treatment results in resolution of bullous lesions in the affected patients.     

Relationship between clinical findings of patients with bullous pemphigoid and antigens recognized by their circulating antibasement membrane zone antibodies

INTRODUCTION: Clinical features and extent of bullous pemphigoid lesions differed widely among patients. The pathogenic role of anti-BPAG2 antibodies has been recently demonstrated. The aim of this study was to analyze the relationship between clinical features of bullous pemphigoid patients and the antigens recognized by their serum. PATIENTS AND METHODS: One hundred and twelve bullous pemphigoid patients were included in this prospective multicenter study. Inclusion criteria were the following: 1) diagnosis of bullous pemphigoid established on the presence of 3 of the 4 clinical features of bullous pemphigoid, histological picture of bullous pemphigoid and positive direct immunofluorescence; 2) serum available for immunoblotting studies. The clinical and biological findings were prospectively recorded on standard forms. Sera were collected and analyzed using indirect immunofluorescence and immunoblotting on human epidermal extracts. RESULTS: Analysis of patient's clinical features depending on the antigens recognized by their serum showed that patients whose serum contained anti-BPAG1 antibodies had more frequently pruritus, blisters on the lower limbs and a positive indirect immunofluorescence. Patients whose serum contained anti-BPAG2 antibodies had blisters more frequently localized on the head, and a more frequently negative indirect immunofluorescence. Patients whose serum was negative by immunoblotting had less frequently urticarial and/or eczematous lesions, bullae less frequently localized on the lower part of the trunk, abdomen and lower limbs, lower eosinophilia and a more frequently negative indirect immunofluorescence. CONCLUSION: Patients with circulating anti-BPAG1 antibodies exhibited the most typical, clinical and biological features of bullous pemphigoid.

IgA-lineare Dermatose im Erwachsenenalter mit klinischen Zeichen eines Stevens-Johnson-Syndroms

Immunohistologically linear IgA disease presents with unambiguous features, whereas clinical manifestations are variable. It sometimes shows similarity to other bullous dermatoses such as bullous pemphigoid and dermatitis herpetiformis. A 73 year old female patient was referred with the diagnosis of bullous pemphigoid. One day after admission clinical examination revealed the classical features of Stevens-Johnson syndrome (SJS): widespread confluent atypical target lesions, partly raised, partly flat with central blisters, and erythematous spots, but few typical targets, as well as blisters and large areas of skin detachment on her back and buttocks, accompanied by erosions of the oral and genital mucosa. Direct immunofluorescence performed on peri-lesional skin showed linear deposition of IgA along the basement membrane zone, leading to the diagnosis of linear IgA disease of adults. Our case report shows that linear IgA disease may present with the clinical pattern of SJS.     

Coexistence of lichen planus and bullous pemphigoid (an immunofluorescence study of a "lichen pemphigoides") (author's transl)]

A 35 year old black man presented with a generalized eruption of lichen planus; subsequently tense blisters appeared within the lichenoid lesions and on clinically normal skin. Histopathological characteristics of lichen planus were present in the papules, and those of bullous pemphigoid were seen in the bullae taken from non-lichenoid skin. Direct immunofluorescence studies revealed immunological characteristics of lichen planus in skin and mucosal lesions of L. P. Bound IgG and beta1 C/beta1 A with tubular patterns were detected at the dermo-epidermal junction in all the skin fragments (clinically normal skin, bullous lesions lichenoid skin and mucous lesions). Indirect immunofluorescence studies showed at several intervals that the patient had circulating antibasement membrane zone antibodies (IgG; titres 1/50). This is the third published case in which immunofluorescence studies have established the "pemphigoid" nature of some bullous lichen planus. These findings are in favour of an immune disorder in lichen planus.

Frequency of IgA antibodies in pemphigus, bullous pemphigoid and mucous membrane pemphigoid

Circulating and bound IgA antibodies can be found in the autoimmune blistering diseases, but their prevalence, clinical relevance and target antigens remain unknown. Thirty-two patients with pemphigus, 73 with bullous pemphigoid and 28 with mucous membrane pemphigoid were studied retrospectively. Direct immunofluorescence (DIF) analysis of IgG, IgA, IgM and C3 was carried out for all cases. Sera were studied by standard indirect immunofluorescence, indirect immunofluorescence on salt-split skin, immunoblotting for bullous pemphigoid and mucous membrane pemphigoid and ELISA for pemphigus. With DIF, we found IgA autoantibodies in 22 of all 133 cases. Circulating IgA antibodies to skin were detected in 2 of 3 IgA-DIF-positive patients with pemphigus, in 3 of 6 with bullous pemphigoid, and in 6 of 13 with mucous membrane pemphigoid. We confirm that the IgA reactivity is more frequently associated with mucous membrane involvement, especially in cases without critical involvement (5/8). The role of IgA and its antigenic specificity in these diseases remain unclear.
