Presence of Ghost Capsules in Stool Mimicking Parasites due to Extended Release Metformin.

BACKGROUND

This case report presents the history, findings, and diagnostic workup of a 28-year-old woman who presented to the hospital with a yellowish, parasite-like structure in her stool.

METHODS

The patient had no significant gastrointestinal complaints other than weight loss and decreased appetite, and no parasites or leukocytes were detected on direct examination of the stool.

RESULTS

No eosinophilia, elevated C-reactive protein or leukocytosis was detected in laboratory tests. It was suggested that the structure in the stool of the patient whose symptoms occurred after taking extended-release metformin could be a ghost tablet, and further investigation was not considered necessary.

CONCLUSIONS

The report emphasizes the importance of considering drug-related side effects, especially ghost pills, in patients with atypical stool findings to avoid unnecessary investigations and anxiety.
