A case report published in Cureus on October 6, 2026 describes a patient with erythrodermic psoriasis who also developed anasarca and lymphadenopathy, a combination of findings that initially resembled lymphoma. According to Cureus, the presentation was significant enough to mimic the blood cancer, meaning the clinical picture pointed toward a different diagnosis than the one eventually identified.
Erythrodermic psoriasis is a rare and severe form of psoriasis in which inflammation affects most of the body's skin surface. Anasarca refers to widespread swelling caused by fluid accumulation throughout the body's tissues, while lymphadenopathy describes enlarged lymph nodes. Both anasarca and lymphadenopathy are features that can raise suspicion for lymphoma, which is what made this case notable, Cureus reports.
The case report's title indicates that the overlap between these dermatologic and systemic findings created a diagnostic challenge. The authors presented the case as an example of how erythrodermic psoriasis, when accompanied by extensive swelling and enlarged lymph nodes, can produce a clinical picture that points away from the actual underlying condition.
Because only the headline and summary of the Cureus report were available, details such as the patient's age, sex, treatment course, and outcome are not included here. The report does not, in the material available, specify how the distinction from lymphoma was ultimately made or what tests confirmed the psoriasis diagnosis.
What to watch next: the full Cureus case report, which may detail the diagnostic steps and clinical course behind this lymphoma-mimicking presentation.
