A 55-year-old man came to see an ophthalmologist with something that seemed obvious: a white meniscus in the lower part of both eyes, typical of an infection called hypopyon. 👁️
But something didn’t add up. The patient already had a complicated medical history: Gaucher disease and B-cell lymphoma. When the doctors extracted a sample of the aqueous fluid for analysis, the surprise was total: they weren’t white blood cells fighting an infection; they were lymphoma cells silently invading his eyes.
The case, published in the Journal of Neuro-Ophthalmology in 2010, describes this phenomenon as ‘pseudohypopyon’: an almost perfect mask that cancer can use to camouflage itself as something much simpler. Despite receiving intensive chemotherapy immediately, the patient died just 14 weeks after that discovery. 💔
