title: Cutaneous pigmented melanocytic tumor in a mouse treated with psoralen plus ultraviolet A radiation.
abstract: A pigmented melanocytic tumor was induced on the treated site of a C3H/HeN female mouse given repeated topical applications of 8-methoxy-psoralen and subsequent exposures to ultraviolet A radiation (PUVA) over a 7-month period. The tumor invaded the subcutaneous tissue and muscle but produced no distant metastases. To our knowledge, this is the first report suggesting a direct relationship between PUVA treatment and the induction of cutaneous melanocytic tumor in mice.
