Eccrine squamous syringometaplasia is a histologic finding associated with chemotherapy administration and other cutaneous diseases. Concentration of the chemotherapeutic agents is believed to effect toxic changes in these epithelial structures. We report the first case of vincristine-induced eccrine squamous syringometaplasia in a 12-year-old patient undergoing treatment for rhabdomyosarcoma.
The irritant effect of exposure to chemicals, including those that usually are not major irritants, and the possible additive effect of simultaneous exposure to different chemicals, should be considered in the differential diagnosis of acute dermatitis of unknown etiology. Moreover, increased reporting of cases of chemical-induced acute irritant contact dermatitis will help lead to crucial early and appropriate treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
