Case report: topical DMSO for mitomycin-C-induced skin ulceration.
Mitomycin-C is a commonly used anticancer drug for patients with advanced anal, breast, colorectal, gastric, lung, or pancreatic cancers. Mitomycin-C can cause severe necrosis and ulceration when extravasated inadvertently into skin and soft tissues following IV drug administration. Local applications of heat, ice, and common antidotes such as glucocorticosteroids and hyaluronidase or sodium thiosulfate have failed to reduce the experimental toxicity of these vesicant reactions in mice. Plastic surgery with split-thickness skin grafting may be required to palliate local pain symptoms and loss of function, although some extravasations heal without any local treatment. This brief communication summarizes two case reports of the treatment of severe mitomycin-C venous extravasations using topical applications of dimethylsulfoxide (DMSO). Although the authors' experience represents the results of DMSO interventions in only two patients, the response to treatment in both patients was so pronounced that others may find this useful in their practice.
