This case report sheds light on the clinical presentation, diagnostic
process, and therapeutic approach for a patient with diarrhea associated
with Blastocystis hominis infection. It is crucial to consider parasitic
infections in the differential diagnosis of chronic diarrhea. The
identification of B. hominis cysts underscores the need for careful
clinical consideration. The successful treatment of this case with
appropriate antimicrobial therapy demonstrates symptom resolution and
highlights the necessity for continued investigation into the pathogenic
role of B. hominis.
