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.
CTCL is a heterogeneous group of non-Hodgkin's lymphomas characterized by chronic inflammation and accumulation of malignant T cells in the skin. In order to carry out research to expand the knowledge and develop more effective treatments, tissue samples from CTCL patients with presumed or known disorders are required and tissue samples from control patients will be required to compare the differences between affected and healthy populations. Scientists will be able to test new ideas and new technologies that are not apparent or available at the present moment from this tissue repository in t…
