Folliculocystic and collagenous hamartoma of tuberous sclerosis complex, not always a single cutaneous lesion

Folliculocystic and collagenous hamartoma (FCCH) is a rare cutaneous manifestation characterized by the presence of single plaques studded with comedo‐like openings and cysts. Although its pathophysiology is still unknown, it has generally been described in men with tuberous sclerosis complex (TSC). We report a case of a one‐year‐old child with two FCCH in the abdominal wall associated with TSC. In our case, a TSC2 mutation was identified.
