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.
