Atypical anterior segment manifestations in extranodal NK/T-cell lymphoma, nasal type, initially presenting as steroid-resistant uveitis in a patient with prior LASIK history: a case report
This case report describes a patient with extranodal NK/T-cell lymphoma, nasal type, who initially presented with steroid-resistant uveitis and later developed two rare anterior segment complications—dynamic posterior capsular deposits following cataract surgery and late stromal infiltration beneath a remote LASIK flap—highlighting the importance of recognizing these atypical ocular manifestations in the context of occult systemic lymphoma.

The human eye is a window to the body, but sometimes that window reflects a disease that originates far away. In the realm of medicine, there are rare cancers that do not start in the eye itself but travel there from other parts of the head and neck. One such disease is a type of aggressive cancer involving specific immune cells, known as natural killer and T-cells. This condition usually begins in the nasal cavity or sinuses, the hollow spaces behind the nose. While it is well known that this cancer can spread to the eyes, it is far less common for it to appear in the eye before doctors even know the cancer exists in the nose. When it does, the symptoms often look like a stubborn, chronic inflammation that does not respond to standard treatments. This creates a diagnostic puzzle: doctors see a severe eye problem that acts like an infection or an autoimmune disorder, but the usual medicines fail to clear it. Understanding how this cancer disguises itself is vital, because missing the true cause can delay life-saving treatment.
This story begins with a fifty-six-year-old woman who had undergone a common vision correction surgery called LASIK about thirty years prior. She arrived at a clinic with worsening vision in her left eye. Doctors found inflammation inside both eyes, a condition known as uveitis, which causes cells to float in the fluid of the eye and can lead to pain and vision loss. They treated her with strong steroid medications, both in drops and as injections directly into the eye, but the inflammation refused to go away. Because the condition was not responding to treatment, she was referred to a specialist hospital for a deeper investigation. The medical team performed a procedure to remove a small sample of the fluid from inside her eyes to examine the cells under a microscope. The analysis showed a mix of immune cells that were active and dividing rapidly, but the results were not enough on their own to confirm a specific type of cancer.
While the eye doctors were working, the patient developed other symptoms. She began to experience swelling around her right eye, and scans revealed a problem in her nasal sinuses. A surgeon removed tissue from her nose and sinuses for testing, and this biopsy provided the definitive answer: she had extranodal NK/T-cell lymphoma, a rare and aggressive cancer of the immune system that typically starts in the nasal area. This confirmed that the eye inflammation was indeed a sign of this cancer, even though the cancer had started in her nose. As she underwent treatment for the cancer, her eyes continued to face new and unusual challenges. She developed cataracts, a clouding of the eye's natural lens, which required surgery. She also suffered from viral infections in the eye and damage to the surface of the cornea, likely caused by the strong chemotherapy drugs used to treat her cancer.
The most striking part of this case, however, involved two strange changes that happened in her right eye after her surgeries. First, after the cataract surgery, a white patch appeared behind the artificial lens that had been implanted. In a typical recovery, such a patch might be a static cloudiness, but in this patient, the white patch was dynamic; it constantly changed its shape and size over time. This behavior was unlike any standard post-surgery complication. Second, the doctors noticed a new area of infiltration, or invasion by cells, deep within the cornea, specifically underneath the flap that had been created during her LASIK surgery thirty years earlier. This was highly unusual because such deep inflammation typically occurs soon after the surgery, not decades later. The doctors treated this area with steroid drops, and it improved slightly, but it never fully disappeared.
The medical team concluded that these two unusual findings—the shifting white patch behind the lens and the deep corneal inflammation under the old LASIK flap—were likely linked to her cancer or the body's immune response to it. However, they could not prove this with absolute certainty. To confirm that the white patch or the corneal area contained cancer cells, they would have needed to perform another invasive surgery to take a tissue sample. The patient declined these additional procedures. Therefore, while the doctors strongly suspected these were manifestations of the lymphoma, they remained clinical observations rather than confirmed facts. The case highlights that in patients with this type of cancer, the eye can show very strange signs, such as deposits that move and change or inflammation that appears in old surgical scars long after the original surgery.
This report serves as a warning and a guide for eye surgeons. It suggests that when a patient with a known or suspected cancer develops strange, changing, or stubborn problems after eye surgery, it may not be a simple complication. Instead, it could be a sign of the underlying disease acting in an unexpected way. In this specific case, the patient's vision in the right eye eventually declined to the point where she could only see hand movements, a result of the combined effects of the corneal issues, the changing deposits, and the ongoing inflammation. The patient passed away after the final follow-up, which prevented any further testing. Nevertheless, the story of her eyes provides a clear example of how a rare cancer can hide in plain sight, mimicking common inflammation and creating unique patterns that doctors must learn to recognize. By paying attention to these atypical signs, such as deposits that do not stay still or inflammation that appears in old surgical sites, specialists can potentially identify the true cause sooner and guide patients toward the correct systemic treatment.
