Diagnosis of cervical chordoma by fine needle aspiration biopsy.
A case of cervical chordoma diagnosed by fine needle aspiration (FNA) is presented. The cytologic criteria for differentiating chordoma from chondrosarcoma and metastatic adenocarcinoma, the main diagnostic problems, include the finding of physaliferous cells and the presence of bland nuclear features. Significantly, chordomas lack true signet-ring cells. FNA of these rare midline vertebral neoplasms, which produce pain and spinal cord compression, can greatly facilitate diagnosis and optimal treatment.

Giardia lamblia in peritoneal fluid.
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.
