Strongyloides stercoralis is a small intestinal nematode that has the ability to multiply within the human host. Because of the potential opportunistic behavior of this parasite, immunocompromised patients may develop fatal disseminated infections. ⋯ Rarely recognized is the presence of widespread petechiae and purpura that may develop in patients with disseminated infections. A 64-year-old immunosuppressed man developed fatal extraintestinal S stercoralis infection with extensive purpura associated with massive invasion of the skin by migrating larvae.
