대장 내시경 생검으로 진단된 분선충증- 2예 보고 - = Two Cases of Strongyloidiasis Diagnosed by Colonoscopic Biopsy

다국어 초록 (Multilingual Abstract)

Strongyloides stercoralis is an intestinal nematode that is able to infect the host tissue and
persist for many years through autoinfection, and it causes life-threatening hyperinfection in
immunocompromised hosts. We report here on two cases of strongyloidiasis that were diagnosed
by colonoscopic biopsy. One case was a 73-year-old woman who was hospitalized
with complaints of melena. She was being treated with corticosteroid due to her asthma and
rheumatoid arthritis. The other case was a 63-year-old man who suffered with abdominal discomfort
and severe loss of body weight (18 kg) for 2 months. In both cases, colonoscopic
examination revealed polyps and petechiae at the entire colon. Microscopically, a small illdefined
granuloma with a longitudinally sectioned parasite was seen on the colonoscopic
biopsy. Endoscopic examination was done after suspecting parasitic infestation. The gastric
and duodenal mucosa showed numerous cross sections of adult worms, eggs and larvae
that were developing in crypts. Even if such a patient is in an asymptomatic state, this illness
must be treated due to the potential for fatal autoinfection.
