Should eye exposure or mucosal contact occur, immediately irrigate for at least 15 minutes with copious amounts of water, followed by immediate medical consultation • Secondary exposure: Avoid direct skin contact with VALCHLOR in individuals other than the patients due to risk of dermatitis, mucosal injury, and secondary cancers • Dermatitis: Dermatitis may be moderately severe or severe.

About Mycosis Fungoides
Mycosis fungoides (MF) accounts for almost 50% of all primary cutaneous lymphomas, a form of non-Hodgkin’s lymphoma. The cause of MF remains unknown and there are no curative treatments. MF has an indolent clinical course, slowly progressing from patches to thicker plaques and eventually to tumours over years or decades. Signs include rash, patch and plaques with severe itch. MF typically affects older adults (median age at diagnosis: 55-60 years) with male predominance. In the U.S., approximately 15,000 patients are affected by stage IA-IB MF-CTCL. Epidemiologic studies based on the Surveillance, Epidemiology, and End Results (SEER) databases have shown a ∼threefold increase in CTCL incidence in the US during the last 25–30 years.2
