Abstract
Compartment syndrome is a surgical emergency that requires immediate decompression. We know of no documented cases that describe ecthyma gangrenosum as a primary cause of compartment syndrome. We present a case of a baby with x-linked agammaglobulinaemia who developed compartment syndrome associated with systemic Pseudomonas aeruginosa infection and ecthyma gangrenosum of the leg. He was treated by debridement and fasciotomies followed by primary closure and skin grafting and made an uneventful recovery.
