Large congenital myopericytoma of the lower eyelid.

Congenital fibrous soft tissue tumors in the eyelids are exceptionally rare, with only seven cases of neonatal myofibromas reported. Myopericytoma, a variant with pericytic differentiation, has not previously been described in neonatal eyelid tumors. This report details a case of a massive congenital myopericytoma in a newborn's lower eyelid. The lesion had a broad area of adhesion to the anterior lamella of the lid. After resection, when the child was 11 days old, the resulting defect was successfully reconstructed with a V-Y type perforator-based flap.
