Congenital Epidermal Inclusion Cyst On the Breast: A Case Series of a Rare Entity

Epidermal inclusion cysts (EICs) are the most common cutaneous cysts, occurring anywhere in the body but infrequently on the breast. It is usually seen in the third and fourth decades of life and very rarely seen in children. They can be either congenital or posttraumatic. Most of the EICs described in children were secondary to trauma. Congenital EIC on the breast is quite a rare entity. Thus, we herein describe two cases of congenital EIC on the breast in two infants of 3 months and 9 months of age, which to the best of our knowledge has not been reported previously.
