Researchers are building a collection of tissue and body samples to better understand cutaneous T cell lymphoma (CTCL), a rare cancer that affects the skin. By comparing samples from patients with CTCL, people with common skin conditions like eczema or psoriasis, and healthy volunteers, scientists hope to discover new ways to diagnose and treat this disease more effectively.
Right now, doctors and researchers don't fully understand why cutaneous T cell lymphoma develops or why it affects people differently. By creating a repository of samples from many different people, researchers can test new ideas and technologies today and in the future that might lead to better treatments for patients.

If you join this study, you will donate samples including a small skin biopsy, blood, and swabs from your skin, nose, and mouth, plus samples of urine and stool. The study does not involve taking any medication or undergoing treatment—it is purely a collection of samples to build a research repository. Your samples will be stored and used by researchers now and in the future to study how cutaneous T cell lymphoma develops and to test new research ideas.
