Percutaneous absorption of I,3-bis (2-chloroethyl)-I-nitrosourea (BCNU, carmustine) in mycosis fungoides

Abstract
The total percutaneous absorption of I,3‐bis(2‐chloroethyl)‐i‐nitrosourea (BCNU, carmustine) in 5 patients with mycosis fungoides, based on the 5 day urinary excretion of 14C‐labelled BCNU, ranged from 5 to 28%. Absorption through diseased skin was greater than through uninvolved skin.
