Pelvic Abscess Secondary to Mycoplasma Hominis after Vaginal Laceration

Mycoplasma hominis frequently colonizes the urogenital and respiratory tracts of healthy individuals. It has also been associated with genitourinary tract and extragenital syndromes.

We present a 14-year-old girl who developed a pelvic abscess secondary to M. hominis after a vaginal laceration during sexual intercourse. Despite drainage and broad-spectrum antimicrobial therapy, the patient remained symptomatic until M. hominis was identified and specific therapy instituted.

Health care providers need to be aware of the potential for M. hominis as a causal agent in patients who present with pelvic abscesses after vaginal trauma. This case highlights the challenges that exist in the diagnosis and treatment of M. hominis, because bacterial cultures are often negative and empiric antimicrobial agents do not provide adequate antimicrobial coverage.
