BULLOUS PEMPHIGOID
BULLOUS PEMPHIGOID (See also Section 6) ICD-10: L12.0
• In contrast to pemphigus vulgaris, oral involvement is in only 10% to 30% of bullous pemphigoid cases.
• Findings: Blisters (Fig. 33-26), which initially are tense, erupt on the buccal mucosa and the palate, rupture, and leave sharply defined erosions that are practically indistinguishable from those of PV or cicatricial pemphigoid (see Fig. 33-24).
• However, erosions less painful and less extensive than in PV.
• Treatment may be topical.
• Diagnosis, see “Bullous Pemphigoid” in Section 6.
FIGURE 33-24 • Pemphigus vulgaris Shallow ulcers and erosions with underlying beefy erythema/dermal tissue are commonly aggravated by trauma from swallowing spicy foods or citrus.
FIGURE 33-26 • Bullous pemphigoid In the initial stages, bullae may be seen, which invariably rupture, leaving erosions that are difficult to distinguish from cicatricial pemphigoid or pemphigus vulgaris.
