Q
A 32-year-old woman presented to the outpatient clinic with a 2-month history of anal pruritus and bleeding. Her abdominal examination was normal, and rectal examination revealed hemorrhoids. What is the most likely diagnosis?
Hemorrhoids Enterobiasis Trichuriasis Strongyloidiasis Colorectal cancer
A
The correct answer is enterobiasis. The patient underwent colonoscopy, which revealed a 1-cm worm moving in the anus. The nematode was identified as a female Enterobius vermicularis – also known as a pinworm. The patient’s 5-year-old daughter also reported anal pruritus and had classmates in whom pinworm infection had recently been diagnosed.
