Persistent trichomoniasis in a man in his early 90s with a history of prostatic hyperplasia: A case report

Abstract

The protozoan Trichomonas vaginalis is a parasite associated with numerous sexually transmitted infections worldwide. In males, although Trichomonas vaginalis infection (also known as trichomoniasis) often remains asymptomatic, it can lead to conditions such as prostatitis or urethritis. Herein, we report the case of a man in his early 90s who was admitted to a hospital in northern Iran with mild dysuria, whose precise onset remained unclear. He had a history of chronic prostate discomfort for several years and acknowledged having multiple sexual partners over the past two decades. He complained of dysuria; therefore, urinalysis was performed, which detected trichomoniasis. He received treatment with metronidazole, resulting in the resolution of urinary symptoms and elimination of the parasite. This case highlights the importance of considering the possibility of trichomoniasis in men, especially older men, as they may face an increased risk of inflammation and prostate cancer.
