Extragenital granuloma inguinale mimicking a soft-tissue neoplasm: a case report and review of the literature.

Granuloma inguinale has been reported to mimic squamous cell carcinoma, as well as sexually transmitted diseases. We describe a rare case of extragenital granuloma inguinale that mimicked a soft tissue neoplasm in an 18-year-old pregnant woman who presented with cervical and labial ulcers. An elective cesarean section was performed, at which time a retroperitoneal mass that involved the right ureter was found. At frozen section, the mass had a xanthogranulomatous appearance consistent with a soft-tissue neoplasm. Special stains of the permanent sections revealed the pathognomic features of granuloma inguinale.
