A 53-year-old woman had a red, itchy patch on her ankle for five years. Doctors treated it as eczema, but it never got better. Finally, a biopsy revealed the truth: she had a rare form of skin lymphoma called Pagetoid reticulosis, also known as Woringer-Kolopp disease.
Doctors prescribed a strong topical steroid called clobetasol propionate, applied twice a day. The result was surprising: the lesion cleared up almost completely. Lab tests showed the cancer cells were a type of T-cell lymphoma, with some unusual markers. The cancer cells were growing fast, with a Ki-67 index of about 40%, meaning 40% of cells were actively dividing.
This is just one person's story, so we can't assume the same treatment will work for everyone. But it shows that when a rash doesn't respond to standard treatments, a biopsy is crucial. Early diagnosis of this rare condition can prevent years of ineffective treatment and unnecessary worry.
Common questions
What is Pagetoid reticulosis?
Pagetoid reticulosis, also called Woringer-Kolopp disease, is a rare type of skin lymphoma. It often looks like a red, scaly patch that doesn't heal. It's a slow-growing cancer of immune cells called T-cells.
How was it treated in this case?
In this case, the woman applied a strong steroid cream called clobetasol propionate to the affected area twice a day. After treatment, the skin lesion showed substantial clinical resolution, meaning it cleared up significantly.
Is this treatment safe for everyone?
This was a single case report, so we don't know if the treatment is safe or effective for others. Side effects were not reported in this study. Always talk to your doctor before using any medication.
How is this different from eczema?
Eczema is a common inflammatory skin condition that usually responds to steroid creams. Pagetoid reticulosis is a rare cancer that can look like eczema but doesn't get better with standard treatments. A biopsy can tell them apart.
