Douche-induced pelvic peritoneal starch granuloma.

Area of Science:

• Gynecologic Pathology
• Peritoneal Diseases
• Microscopy

Background:

• Granulomatous peritonitis is a rare condition often associated with infections or foreign material.
• This case presents a unique etiology in a patient with no surgical history.

Observation:

• A patient presented with vaginal bleeding and an ovarian mass.
• Laparotomy revealed findings suggestive of peritoneal carcinomatosis.
• Histological examination identified focal chronic granulomatous peritonitis.

Findings:

• Polarization microscopy confirmed the presence of starch granules within the peritoneum.
• The granulomatous inflammation was attributed to exogenous starch introduced via vaginal douching.

Implications:

• This case highlights an unusual cause of granulomatous peritonitis mimicking gynecologic malignancy.
• It underscores the importance of considering iatrogenic or environmental factors in peritoneal disease diagnosis.
• Patient history regarding product use is crucial for accurate diagnosis.
