Primary Tubo-Ovarian Mucormycosis in an Immunocompetent Adolescent Female: A Rare Case Report and Review of Management
This case report describes a rare instance of primary tubo-ovarian mucormycosis in an immunocompetent 17-year-old female that mimicked a tubo-ovarian abscess, highlighting the critical importance of prompt histologic diagnosis, antifungal therapy, and radical surgery for successful management.

Most people understand that the human body is a fortress, and when its defenses are weakened by illness or medication, invisible invaders like fungi can slip inside and cause serious trouble. A particularly aggressive group of these fungi, known as Mucorales, is famous for attacking people with compromised immune systems, such as those with uncontrolled diabetes or cancer. These organisms are dangerous because they do not just sit on the surface; they invade blood vessels, cut off the blood supply to tissues, and cause rapid death of the flesh they touch. While this infection is well-known in the lungs, sinuses, or skin, it is almost unheard of in the reproductive organs of young, healthy people. When it does appear there, it is so rare that doctors often mistake it for a common bacterial infection or even a tumor, leading to delays in the correct treatment.
This story comes from a medical report detailing a case that defied these expectations. A seventeen-year-old girl, who had no history of immune system problems, arrived at a hospital in Pakistan suffering from months of severe lower abdominal pain, high fevers, and a growing lump in her lower right side. She was thin and weak, and her temperature spiked dangerously high every day, often reaching 104 degrees Fahrenheit, despite taking medicine to lower it. Doctors initially suspected a standard bacterial infection of the ovaries and fallopian tubes, a condition called a tubo-ovarian abscess, which is common in young women. They ran blood tests that showed high levels of inflammation and performed an ultrasound that confirmed a complex, fluid-filled mass. Because the girl was not getting better with standard antibiotics, the medical team decided to perform emergency surgery to drain the infection.
Inside the operating room, the surgeons found a large, complex mass on the right side containing about 500 milliliters of pus. They drained the fluid and took samples of the tissue to be examined under a microscope. This is where the mystery deepened. The microscopic analysis revealed that the infection was not bacterial, but fungal. The tissue showed broad, ribbon-like strands of fungus that had destroyed the ovarian tissue. A special stain used to highlight fungal cells turned a deep, positive color, confirming the presence of Mucorales. This was a startling discovery because the patient had a healthy immune system, and this specific type of fungal infection in the reproductive organs of an adolescent had never been documented before.
The medical team immediately shifted their strategy to fight the fungus. They started the patient on a powerful antifungal drug called Amphotericin B, which is usually the first choice for this infection. However, the girl reacted poorly to the medicine, suffering from severe vomiting and drowsiness, so they had to stop it. With other preferred medications unavailable, they switched her to a different antifungal called Voriconazole. For a short time, the girl seemed to recover; her fever broke, she became alert, and her blood markers for inflammation began to drop. She was sent home after thirty-one days, feeling better and taking oral medication.
But the victory was only temporary. About a month after leaving the hospital, she returned with the same severe pain, vomiting, and high fevers. A new ultrasound showed that the large mass in her abdomen had not shrunk; it remained exactly the same size, measuring about 110 milliliters in volume. The fungus had not been killed by the medication. Furthermore, her kidneys were now struggling, which meant she could not safely take the stronger antifungal drugs again. The doctors realized that the medicine alone could not clear the infection because the fungus had created a solid, dead mass that drugs could not penetrate. The only way to save her was to remove the infected tissue entirely. She underwent a second, more extensive surgery to completely excise the mass.
This case teaches a vital lesson about how rare diseases can hide in plain sight. It shows that even in a young person with a strong immune system, a fungal infection can take hold in the reproductive organs and mimic a common bacterial abscess. The report highlights that when a patient does not respond to standard treatments, doctors must look deeper and consider unusual causes. It also underscores that for this specific type of aggressive fungal infection, removing the dead tissue surgically is often just as important as using medicine. Without that second, radical surgery, the infection would likely have continued to grow and could have been fatal. The successful outcome relied on recognizing that the initial improvement was a false signal and that the physical removal of the infected mass was the only path to a cure.
