Infantile anogenital digitate keratoses (IADK) is an idiopathic, benign condition that presents as digitate, keratotic projections in the anogenital area of infants. It is typically seen in the perianal area but may also more rarely be found in the genital skin, particularly in female infants.
IADK is more commonly reported in males than in females. It appears in the first few months of life, and lesions typically regress spontaneously within several months.
