Unusual subepidermal bullous diseases with immunologic features of bullous pemphigoid.

Sixty-seven patients with histologic and immunologic features of bullous pemphigold (BP) were evaluated. Eleven patients had a localized blistering disease that was predominantly confined to one area of the body, most commonly the lower extremities. Two patients displayed a dapsone-responsive blistering disease that was characterized by a flexural distribution of ten to 20 1-cm or less, intensely pruitic, subepidermal bullae and linear IgA basement membrane zone deposition. Two patients had a chronic recalcitrant generalized scarring, hyperkeratotic, subepidermal blistering eruption that demonstrated serologic and direct immunofluorescence (IF) findings of BP. One patient displayed grouped small vesicles surmounted on an erythematous base; the clinical diagnosis was dermatitis herpetiformis, but direct IF examination of the biopsy specimen showed features of BP. One patient with epidermolysis bullosa acquisita had serologic and direct IF features suggestive of BP.

Nevus of large spindle and/or epithelioid cells (Spitz's nevus).

By now it is well recognized that there is a benign melanocytic nevus, common in the young and common enough in adults, that has histological features that are confusable with those of malignant melanoma. The anomaly is usually referred to as benign juvenile melanoma, sometimes as Spitz's nevus, and, by some histopathologists, as spindle and epithelioid cell nevus. All the histological subtleties and variations of the condition are still not fully appreciated and some of them are still being misinterpreted as those of malignant melanoma. We herewith present a study designed to clarify the issue and offer firm criteria for histological differentiation of the nevus in point from malignant melanoma. We also suggest a new name for it and supporting arguments therefor.

Bullous pemphigoid. Clinical and immunologic follow-up after successful therapy.

Thirty-six patients with bullous pemphigoid (BP) have been periodically evaluated for four years. This study demonstrates that BP may occur in a transient predominantly localized form that remits spontaneously, and most BP patients after successful therapy remain in prolonged clinical remission. In this study, all patients with active or recurrent disease had IgG and/or C3 basement membrane zone (BMZ) deposition. Serum anti-BMZ antibodies was an inconstant feature. In most instances, clinical remission of BP was associated with disappearance of BMZ ig and C3 deposition and serum BMZ antibodies. Fluorescein-conjugated, antihuman C3 appears to be a more sensitive immunoreagent than antihuman, class specific, immunoglobulin antisera in detecting positive BMZ staining in BP. Combined therapy with azathioprine plus prednisone appears to be superior to prednisone alone in the treatment of BP.

Pemphigus and myasthenia gravis.

Various forms of true pemphigus have been reported to occur with myasthenia gravis, with and without thymoma, more frequently than can be ascribed to chance. A57-year-old woman with myasthenia gravis in remission developed pemphigus foliaceus. No roentgenologic evidence of a thymoma was present. Antinuclear antibodies caused interference with indirect immunofluorescent determination of pemphigus antibody. Indirect immunofluorescent studies showed no evidence for cross-reactivity between intercellular substance antibody and thymic components, as is found in the case of antiskeletal muscle antibodies with thymic myoid cells. The concurrence of these two diseases may involve the failure of a subgroup of thymic-dependent lymphocytes to suppress underlying autoimmune phenomena.
