Bartholin's gland cyst caused by Sneathia amnii: a case report.

BACKGROUND: Sneathia amnii is a conditional pathogen of the female genital tract that is involved in bacterial vaginosis and poor reproductive and perinatal outcomes. Few studies have reported subcutaneous cysts following invasive infection caused by S amnii.

CASE PRESENTATION: Here we report the case of a 27-year-old woman who presented with Bartholin's gland cyst due to S amnii infection, and was successfully treated with surgical neostomy and antibiotic agents. The isolate was gram-negative, bacillary, anaerobic, and was identified by polymerase chain reaction (PCR) amplification of the 16 S rRNA.

CONCLUSIONS: S amni is an important but underappreciated pathogen that needs further investigation. This report describes the microbial and pathogenic characteristics of S amnii and is expected to provide a valuable reference in obstetric and gynecologic clinical practice.
