ABSTRACT
UNLABELLED: The case of a 76-year-old woman who developed blisters on both forefeet within 2 weeks of bilateral forefoot surgery is reported; the diagnosis of bullous pemphigoid was made by histological and immunofluorescence studies. The pathogenesis and management of this autoimmune condition, which occurs mainly in patients older than 70 years and may occasionally be associated with surgical wounds, are reviewed. It is important for foot and ankle specialists to be aware of and consider the diagnosis when a bullous contact dermatitis-like eruption persists at a surgical site. LEVEL OF EVIDENCE: Therapeutic Level IV: Case report.

UNLABELLED: A case report of a 55-year-old woman who was being considered for bilateral below knee or Syme's amputations after gangrene at the level of both forefeet due to meningococcal septicaemia is described. An expectant approach for 6 months revealed that the tissues deep to the necrotic skin were viable and she was subsequently able to mobilize independently with normal footwear after bilateral toe amputations at the metatarsophalangeal joint levels. This case and a literature review suggest that the demarcation of healthy skin from necrotic skin (eschar) should not dictate the level of amputation in dry gangrene of the foot following meningococcal septicemia. Magnetic resonance imaging can overestimate the degree of muscle necrosis. Treatment should be individualized for each patient, but advice should include the option of prolonged conservative treatment to preserve limb length and function. LEVEL OF EVIDENCE: Therapeutic, Level IV: Case study.
