Infantile anogenital digitate keratoses.

Infantile anogenital digitate keratoses (IADK) represent a distinct and under-recognized pediatric condition of the perianal area of infants, significantly more frequent in males than females. The average age of onset is 3.2 months, and it is self-remitting by 2 years of age. Perianal spiny keratoses resistant to usual topical therapies are the hallmark of IADK. We present a series of three cases of IADK seen at the dermatology clinic of the CHU Sainte-Justine to raise awareness on this pediatric condition, and to prevent invasive workup.
