Tissue Repository: CTCL Collection Protocol

Summary

This document is a protocol for a non-interventional human research study in which the investigator hopes to better understand the changes that take place in T cells in Cutaneous T-cell lymphoma (CTCL). The purpose of this study is to establish a protocol for the collection and storage of tissue samples from patients with CTCL for future research studies. Collection and storage of tissue samples from control patients will also be carried out.
