ABSTRACT
This chapter presents the case study of a 28-year-old man. He has had dry skin since birth, although it has been worse since he became a teenager. On examination he has normal teeth, hair and nails. He has generally dry skin with prominent adherent grey-brown scales over the extensor surfaces of his neck and limbs. He has adherent bran-like scale throughout his scalp. He is planning to get married and would like information about the risk of his children being affected with the same skin condition. The build-up of adherent scale imparts a ‘dirty appearance’ to the skin. Typically, the ichthyosis involves particularly the posterior neck, upper trunk, and extensor surfaces of the extremities, with sparing of the flexures as well as palms and soles. steroid sulphatase deficiency slows the delivery of an infant because of insufficient cervical dilatation.
