Giardia lamblia is a flagellated protozoan that inhabits the upper portions of the small intestine; trophozoites are the usual stage seen in duodenal aspirates, biopsies of the duodenum and jejunum and, infrequently, in stools, in which cysts are more likely to be found. A unique occurrence of G lamblia cysts and trophozoites within the peritoneal fluid of a patient with a blunt abdominal trauma is reported. Cytotechnologists and pathologists should be aware that trophozoites and cysts of G lamblia may appear in peritoneal lavage fluid from patients with blunt abdominal trauma and duodenal injury, indicating a need for exploratory laparotomy.
