Mycosis fungoides (MF) is the most common type of cutaneous T-cell lymphoma (CTCL). It may arise rapidly in a scar or keloid, presumably due to a long-standing proliferative state or autoimmune theory. There should be a low threshold for performing a skin biopsy if unusual lesions develop at those sites.
Keywords: keloid; mycosis fungoides; scar; tumor.
