title: Cock's peculiar tumour.
abstract: We describe the typical clinical and histological features of a case of giant proliferative pilar cyst which was complicated by severe iron deficiency anaemia. The condition, described by Cock in 1852 and eponymously known as Cock's peculiar tumour, is compared to giant proliferative pilar cyst. These entities are probably synonymous.
