Persistent supravenous erythematous eruption: a rare local complication of intravenous 5-fluorouracil therapy.

We describe a 47-year-old man who developed a linear serpentine erythematous eruption, overlying the superficial veins on both arms, after treatment with intravenous 5-fluorouracil. No evidence of superficial phlebitis or extravasation were observed. Histologically, a prominent vacuolar alteration of basal cells, necrotic keratinocytes, pigment incontinence, and a perivascular lymphocytic infiltrate in the upper dermis were observed. In a review of the literature we encountered only 5 reports of a similar clinicopathologic picture. The term "persistent supravenous erythematous eruption" (PSEE) seems suitable to describe this rare and peculiar cutaneous eruption that develops after intravenous cytotoxic drug treatment.
