초록
Strongyloides stercoralis is endemic to tropical and subtropical regions, and infections are usually asymptomatic. However,immunocompromised patients, such as those receiving immunosuppressive therapy, high-dose steroids, or chemotherapy, can developfatal hyperinfections. An 84-year-old man without any symptoms was diagnosed with strongyloidiasis during a regular screeningcolonoscopy. His medical history only involved a gastric endoscopic submucosal dissection for early gastric cancer 6 months previously. Few cases have been published about asymptomatic strongyloidiasis diagnosed in an immunocompetent host via endoscopic mucosalresection with characteristic colonoscopic findings. We report a case of colon-involved asymptomatic strongyloidiasis with specificcolonic findings of yellowish-white nodules. This finding may be an important marker of S. stercoralis infection, which could preventhyperinfections.
Abstract
Strongyloides stercoralis is endemic to tropical and subtropical regions, and infections are usually asymptomatic. However,immunocompromised patients, such as those receiving immunosuppressive therapy, high-dose steroids, or chemotherapy, can developfatal hyperinfections. An 84-year-old man without any symptoms was diagnosed with strongyloidiasis during a regular screeningcolonoscopy. His medical history only involved a gastric endoscopic submucosal dissection for early gastric cancer 6 months previously. Few cases have been published about asymptomatic strongyloidiasis diagnosed in an immunocompetent host via endoscopic mucosalresection with characteristic colonoscopic findings. We report a case of colon-involved asymptomatic strongyloidiasis with specificcolonic findings of yellowish-white nodules. This finding may be an important marker of S. stercoralis infection, which could preventhyperinfections.
