Introital adenosis associated with the Stevens-Johnson syndrome.

A young woman presented with erosive lesions of the labia minora, which appeared 3 years ago after Stevens-Johnson syndrome. Pathological examination showed 'vulval adenosis'. A similar case has been previously reported. Vaporization by carbon-dioxide laser gave satisfactory results, and after 2 years the patient remains totally cured. We discuss several embryological theories which may explain the mechanism of the vulval adenosis in this patient.
