Cutaneous Hybrid Tumor Composed of Epidermal Cyst and Cystic Pilomatricoma: Unusual Presentation in a Child.

We report a rare case of cutaneous hybrid tumor composed of epidermal cyst and cystic pilomatricoma that presented in an unusual way in a child. A 14-year-old teen girl presented with a skin lesion on the inner side of the left arm, approximately at the level of the elbow. The lesion was initially observed 5 months before and was continuously increasing in size during that time resembling other benign or malignant cutaneous tumors.
