The pigmented epidermal cyst (black keratinous cyst) is peculiar to the Negro race. Ninety‐seven % of our cases occurred in Negroes. Thirty‐seven % of the epidermal cysts in Negroes were heavily pigmented. A relationship between the black keratinous cyst and hemochromatosis has been proposed. A change in the degree of pigmentation is more significant than the histologic demonstration of melanin pigment.
