Psoriasin (S100A7) has originally been described to be expressed by psoriatic keratinocytes possibly as a result of altered differentiation and inflammation. As psoriasin was found to be overexpressed in human breast and bladder cancer suggesting a role in tumour progression, we investigated the expression of psoriasin in human epithelial skin tumours.
