From a Shave to 12 Weeks in Hospital: The Unfolding of a Rare Infection
A 40-year-old woman with no known immune deficiency developed a life-threatening flesh-eating infection after shaving her perineal area and applying a herbal topical product from an alternative practitioner. One week later, she presented at the hospital with progressive labial pain, swelling, vomiting, and lower abdominal pain. Imaging and clinical examination revealed extensive necrotizing fasciitis—a rapidly spreading soft-tissue infection—affecting the perineal region, a form known as Fournier gangrene.
Doctors at King Saud University in Riyadh, who reported the case in the American Journal of Case Reports, said the patient spent 12 weeks in the hospital undergoing multiple surgical debridements, negative-pressure wound therapy, and serial dressing changes. Cultures grew Escherichia coli, Klebsiella pneumoniae, and Enterobacter cloacae, and she received broad-spectrum antibiotics including meropenem before stepping down to amoxicillin-clavulanate. An anal fistula was also discovered and treated, though it remains unclear whether it was the source or a complication.
The combination of shaving—which disrupts the skin barrier—and applying a non-sterile topical preparation likely created a portal for polymicrobial invasion, the authors explained. They emphasized, however, that these factors should be seen as probable contributors rather than definitive causes. The patient ultimately recovered with good function but was left with mild cosmetic deformity from the extensive tissue loss, and she will undergo scar revision surgery a year later. Obesity may have masked early signs and contributed to a diagnostic delay, they noted.
Lead author Dr. Ali Bassi told MedPage Today that the most important lesson is that Fournier gangrene is a clinical diagnosis, not a demographic one: clinicians should suspect it whenever a patient presents with rapidly progressive perineal pain and swelling, regardless of sex or immune status.
What the Case Reveals About Risks and Clinical Management
A Diagnostic Blind Spot in Women
Fournier gangrene is historically perceived as a disease of older, immunocompromised, or diabetic males. This case reinforces that the infection can strike otherwise healthy women, and when it does the initial presentation may be mistaken for a gynecologic condition, delaying aggressive treatment. The patient's obesity may also have obscured early warning signs. The authors stress that mortality in Fournier gangrene can reach 40%, and up to 30% of cases occur in individuals without immunodeficiencies—so demographic assumptions should never override clinical suspicion.
The Shaving-Herbal Combination as a Possible Trigger
The precise cause of the infection remains uncertain, but the sequence of events strongly suggests that shaving created microabrasions that broke the skin's protective barrier, while the non-sterile herbal topical introduced mixed bacteria into the wound. That does not prove causation, Bassi and Alsaleh caution, but it highlights how everyday grooming practices, when paired with unregulated products, can create conditions for polymicrobial invasion. The polymicrobial culture results—E. coli, K. pneumoniae, and Enterobacter—are typical of perineal flora and point to a fecal contamination route, though the anal fistula found during treatment could have been either a pre-existing source or a consequence of the severe inflammation.
