Rapid onset of acute carcinoma of the glans penis arising three years after a lichen sclerosus.

Lichen sclerosus and atrophicus (LSA) is an inflammatory disease of incompletely characterised pathogenesis. If the development of squamous cell carcinoma (SCC) during the evolution of LSA is well described in women, this complication is a matter of discussion in men. We report an unusual case of acute and aggressive SCC which complicated the evolution of an LSA of the glans penis within three years. This type of observation is rarely reported in the medical literature.
