MULTIPLE WARTY DYSKERATOMAS OF THE SCALP

Two patients presented with the unusual condition of multiple warty dy skeratomas on the scalp. Biopsies of affected skin stained positive wi th human keratin monoclonal antibodies HKN-6 and -7, specific for cort ex and inner root sheath of normal human hair, respectively. Multiple warty dyskeratomas are a rare occurrence and their aetiopathogenesis r emains elusive. Positive immunohistochemical staining of a lesion with antikeratin antibodies HKN-6 and -7, specific for human hair keratin, suggests a follicular origin for warty dyskeratoma.
