Eruptive disseminated superficial porokeratosis with rapid resolution: a drug‐induced phenomenon?

We report a case of eruptive disseminated superficial porokeratosis occurring in a 63-year-old man with no history of excessive sun exposure. Unlike disseminated superficial actinic porokeratosis, this condition resolved rapidly with minimal topical treatment. This is most likely to have represented a drug-induced phenomenon, which is very rarely reported in the dermatological literature.
