[Spironolactone-induced pemphigoid].
BACKGROUND
Sporadic observations would suggest that certain drugs play a role in the development of pemphigoid. A recent case-control study on long-term drug use associated with pemphigoid was unable to confirm the suspected role of these drugs, but did demonstrate a significant association between the development of pemphigoid and use of spironolactone.


METHODS
An 82-year-old patient had bullous erythematous lesions on the left thigh suggestive of pemphigoid. Histology and direct cutaneous immunofluorescence confirmed the diagnosis. The patient had been taking alimemazine, adrafinil, flunarizine, spironolactone and furosemide as long-term treatment. Spironolactone alone was withdrawn. The cutaneous lesions regressed and have not recurred during the 18-month follow-up.


CONCLUSIONS
The causal effect of spironolactone in this case of pemphigoid is quite plausible. This hypothesis is favored by the agreement with epidemiological data. Other observations are however required before the causal role of spironolactone in development of pemphigoid can be confirmed.
