Congenital lipomatous tumour, presented as a polypoidal projection on upper eyelid

Abstract

A Japanese baby was born with a polypoidal projection with hair, on the lateral corner of upper eyelid. The tumour had extent to bulbar sub-conjunctival area. He presented no other malformation nor pathological symptoms. There was no sign of association with Goldenhar, hemifacial macrosomia, epidermal nevus or linear nevus sebaceous syndromes. The tumour was resected at his age of 4 months. The ocular conjunctiva was incised but not excised. Histopathologically, it was mainly consisted of multi-lobuled mature adipose tissue, dense fibrous tissue was observed at the centre of mass, assumed to be the link of palpebral tarsal plate to lateral canthal ligament. As for the location and component, the tumour was diagnosed as a lipomatous hamartoma. Detached tarsal plate was reattached to the lateral canthal ligament. Satisfactory result was achieved aesthetically and functionally. Congenital lipomatous hamartoma, with protuberant appendage appearance on eyelid, without syndromic association, is presented.
