Mycosis fungoides (MF) is a type of cutaneous hyperproliferative T-cel
l disorder that may be localized. Although there is considerable contr
oversy regarding whether MF may originate as a non-neoplastic conditio
n, or even whether MF is a neoplastic condition until late in its cour
se, we have seen a few cases undergo what appeared to us to be a clear
progression from an inflammatory disorder to MF. We now report a 32-y
ear-old man with MF most prominent on his right flank and buttock who
developed his patches several weeks following, and in the precise loca
tions in which he had experienced, exposure to toxic chemicals in an i
ndustrial accident. Because of this history, and because all lesions w
ere transient except for these sites, these permanent lesions were tre
ated with local surgical excision. There was no recurrence of disease
at the treated sites, and the progression of MF markedly slowed follow
ing surgery, although he has continued to experience multi-focal trans
ient recurrent disease, controlled by a combination of topical and sys
temic treatments, until the present time. Destructive methods such as
excisional surgery or carbon dioxide laser may be considered a therape
utic option for localized MF.
