Herpes gestationis is a pruritic, blistering disease of pregnancy and the puerperium. The clinical presentation consists of intense itching with widespread erythematous, edematous papules and plaques, grouped vesicles and tense bullae. Through recent advances in the immunopathology of blistering diseases, increased accuracy in the diagnosis of herpes gestationis is now possible.

A 39 years old black woman with systemic lupus erythematosus developed tense bullae on erythematous bases on the flexor surfaces of the forearms and oral cavity. Some blisters healed with atrophy and pruritus was a striking feature. The diagnosis of systemic lupus erythematosus was based upon the following criteria: the typical blush in the butterfly area, alopecia, a painful macular papular eruption on the palms and fingers, fever, arthralgia, anemia, leukopenia, elevation of erythrocyte sedimentation rate and positive ANA. Histologic examination showed a subepidermal bulla formation and perivascular inflammatory infiltrate containing lymphocytes and eosinophils. By indirect immunofluorescence no autoantibodies were detected. Direct immunofluorescence showed deposition of linear IgG. High doses of prednisone brought about clinical remission but there was no response to sulfone. The patient is on maintenance dose. The authors discuss the differences between the three diseases and conclude that the bullous eruption cannot be classified.

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.

An 80-year-old woman was referred to our hospital with a spontaneously appearing bullous dermatosis limited to the soles of both feet, causing an intense pruritus. She also suffered from Parkinson's disease and depression, and had been treated with levodopa, benserazide, and mirtazapine for several years. On clinical examination, we found several tense and hemorrhagic bullae, with a diameter of up to 3 cm, at both plantar sites and multiple, confluent, dyshidrotic vesicles ( Figs 1 and 2). The rest of the skin, including the mucous membranes and palms, was normal. The first clinical diagnosis was podopompholyx, but histopathologic findings and direct immunofluorescence revealed a diagnosis of bullous pemphigoid, showing subepidermal blisters (Fig. 3) and linear deposits of C3 and immunoglobulin G (IgG). Indirect immunofluorescence was positive, the IgG autoantibodies bound to the epidermal site of salt-split skin, and circulating antibodies against bullous pemphigoid antigens 1 and 2 were found. Because of this typical clinical picture, a diagnosis of dyshidrotic pemphigoid, a localized form of bullous pemphigoid, was made. Under systemic treatment with prednisolone, 40 mg/day, the skin healed completely within 2 weeks. Descriptions of dyshidrotic pemphigoid limited to the soles of both feet are very rare, and the clinical findings might easily lead to a misdiagnosis of podopompholyx.

Bullous pemphigoid (BP) is an acquired, pruritic, blistering eruption of the skin that typically presents as large, tense, subepidermal bullae in elderly persons. In this article, we present the case of an 80-year-old man with a 2-year history of generalized pruritus with occasional bullae in healed incision sites on his abdomen. Results of biopsy and direct immunofluorescence testing demonstrated evidence consistent with BP. This case demonstrated a BP flare in surgically treated skin, a phenomenon that has infrequently been reported in the literature.

Bullous pemphigoid (BP) is the most frequent autoimmune blistering skin disease of the elderly. It is mediated by circulating antibodies directed against two hemidesmosomal proteins of the dermal epidermal junction: BPAG1 and BPAG2. Clinical features consist of pruritus and tense blisters usually surrounded by erythema. Blisters sometimes evolve to erosions, become haemorrhagic or even large erosive areas. Lesions heal without scarring. Lesions are symmetrically located on the thighs, legs, trunck and arms. Mucous membranes are usually uninvolved. Histological examination of a skin biopsy specimen shows a subepidermal blister with eosinophils within the blister and the superficial dermis. Direct immunofluorescence shows linear IgG and/or C3 deposits along the dermal epidermal junction. In France and in Europe, most patients are now treated using topical steroid therapy (clobetasol propionate).

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.

A 73-year-old woman with a 50-year history of psoriasis was referred to our clinic with a 4-month duration of tense bullae on erythematous base and erosions localized on her lower extremities and torso (Figure 1A). Neither the oral nor the ocular mucosa had been involved. The lesions were intensively pruritic, significantly affecting the quality of her life. At the time of the examination, the patient presented with psoriatic plaques with adherent scales confined on the scalp (Figure 2A). According to the patient's history, her limited psoriasis was partially controlled with occasional topical medications (topical corticosteroids, calcipotriol, and tar shampoo). She also had insulin-dependent diabetes mellitus, asthmatic bronchitis, and partially controlled hypertension with hyperlipidemia. A biopsy specimen was taken from lesional skin on her feet, and a histological examination showed a subepidermal blister with an inflammatory cell infiltrate in the upper dermis. No drugs were incriminated, and diagnosis of bullous pemphigoid was confirmed by Western immunoblotting of serum. Laboratory investigation revealed mild thrombocytopenia of 110,000/mm(3), cholesterol 279 mg/dL, and triglycerides 210 mg/dL. The patient could not tolerate prednisolone and cyclosporine because of hypertension and diabetes, or azathioprine because of the mild thrombocytopenia; she did not consent to receiving biologics. Mycophenolate mofetil (MMF) was then considered a choice. The patient agreed, and she was initially administered 1000 mg/d. After 2 weeks, the dosage increased to 1000 mg twice a day because of the formation of new blisters. Within 8 weeks of treatment with MMF 2000 mg/d, marked improvement was observed and her pruritus resolved. Complete remission of bullous pemphigoid and psoriasis was achieved within 3 and 4 months, respectively. Routine laboratory studies were performed before treatment and every month during therapy, and MMF was tolerated without side effects. The treatment was continued for 6 months with no subsequent relapse of the dermatoses (Figure 1B and Figure 2B).

A 30-year-old man diagnosed with human immunodeficiency virus (HIV) infection 10 years earlier, presented with large tense blisters associated with minimal itching of 10 days' duration. He had no history of oral or genital erosions or ulcerations and showed no symptoms of HIV-related illnesses. Highly active antiretroviral therapy (HAART) had been started 6 weeks earlier when his CD4 count was 116/mL. He initially received nevirapine 200 mg once daily; after 2 weeks with no skin eruptions or other adverse reactions, the dose was increased to 200 mg twice daily. Other components of his HAART included lamivudine and stavudine. The patient was not taking any other prescription or alternative medicines. During the past year, he experienced 4 episodes of intensely itchy urticarial lesions that subsided with antihistamines. The present episode of bullous lesions was also preceded by urticarial lesions. On examination, he had multiple, large, tense bullae over relatively normal-looking skin involving all parts of the body (Figure 1). There were a few well-defined erosions. Nikolsky and bullae spread signs were negative, and no oral or genital erosions or ulcerations were noted. Results of a complete blood count, renal and liver function tests, and chest x-ray were within normal limits. Skin biopsy from one of the blisters showed a subepidermal bulla filled with eosinophils and polymorphonuclear leukocytes (Figure 2). The underlying dermis showed perivascular inflammatory infiltrate composed of polymorphonuclear and lymphomononuclear cells. The overall features were suggestive of bullous pemphigoid. A direct immunofluorescence test could not be done because of possible risk of cross-infection to the operator of the cryostat. Workup for herpes simplex virus and cytomegalovirus infection also could not be performed. HAART was discontinued temporarily with the suspicion that it was the causative factor. The patient was started on oral prednisolone 40 mg/d and topical clobetasol propionate (0.05%). Within 1 week of treatment, he had significant improvement with almost complete disappearance of the lesions. A few small, tense vesicles continued to appear between. Once the lesions completely disappeared, the prednisolone was gradually tapered off and all the components of HAART were resumed. The patient did well without any recurrence of lesions, thus virtually excluding HAART as the cause of the bullous pemphigoid-like eruptions. Subsequently, he did not return for follow-up.

PURPOSE: To report a first case of bullous pemphigoid (BP) following intravenous fluorescein for fundus angiography. Clinical Features: A 70-year-old male patient was admitted to the intensive care unit with BP and sepsis. He reported a history of fundus fluorescein angiography with a pre-diagnosis of senile macular degeneration 2 months prior to presentation. At that time, fluorescein extravasated at the antecubital region. Following the procedure, pruritus and erythema began at the wrists bilaterally, and quickly spread to the entire body. The patient also reported a history of allergy to human albumin solution (Plamasteril(R); Abbott) 15 years before, during bypass surgery. On dermatologic examination, erythematous patches were present on the scalp, chest and anogenital region. Vesicles and bullous lesions were present on upper and lower extremities. On day 2 of hospitalization, tense bullae appeared on the upper and lower extremities. The patient was treated with oral methylprednisolone 48 mg (Prednol(R); Mustafa Nevzat), topical clobetasol dipropionate 0.05% cream (Dermovate(R); Glaxo SmithKline), and topical 4% urea lotion (Excipial Lipo(R); Orva) for presumptive bullous pemphigoid. Skin punch biopsy provided tissue for histopathology, direct immunofluorescence examination, and salt extraction, which were all consistent with BP. After 1 month, the patient was transferred to the intensive care unit with sepsis secondary to urinary tract infection; he died 2 weeks later from sepsis and cardiac failure. CONCLUSIONS: To our knowledge, this is the first reported case of BP following fundus fluorescein angiography in a patient with known human albumin solution allergy. Consideration should be made to avoid fluorescein angiography, change administration route, or premedicate with antihistamines in patients with known human albumin solution allergy. The association between fundus fluorescein angiography and BP should be further investigated.
