Bullous dermatosis caused by Staphylococcus aureus in locus minoris resistentiae

A case of Staphylococcus aureus--induced bullous dermatosis limited to the sites of glucocorticosteroid-induced striae atrophicae is described. Skin with compromised mechanical integrity may be more susceptible to disruption by invasion of bacteria and/or by their exotoxin. The pathogenesis of striae atrophicae and the mechanism of blister formation by S. aureus are reviewed in an effort to relate these two phenomena.
