Dactinomycin-induced, severe lichenoid eruption in a child.

There is little information in the medical literature about skin rashes associated with dactinomycin in the absence of radiotherapy. We report a 12-month-old male child who developed a severe cutaneous reaction that consisted of a widespread pruritic papular eruption associated with fever and a poor general state after dactinomycin administration. Skin biopsy specimen findings confirmed the diagnosis of lichenoid eruption. The rash improved with topical steroid treatment and completely resolved within 1 month with persistence of a residual mild hyperpigmentation. Dactinomycin administration was discontinued for the remaining cycles of chemotherapy.
