CONGENITAL DIFFUSE INFILTRATING LIPOMATOSIS OF FACE (CDIL-F) – A RARE ENTITY

Abstract

Congenital infiltrating lipomatosis of the face is a rare and definite clinical entity of unknown etiology. It comprises a subgroup of lipomatous tumors. It is congenital in origin and occurs in infancy or in early childhood. It is characterized by diffuse infiltration of mature adipose tissues over normal muscle fibers, rapid growth associated with osseous hyperplasia with a high recurrence rate after surgical intervention. Complete surgical excision is difficult due to diffuse infiltration and involvement of important facial structures. Till now, 14 cases have been reported in the literature. We report a case of 4 year old male child presenting with diffuse painless swelling on right side of face showing diffuse fat deposition in soft tissues in right malar region with thickening of right masseter showing fatty infiltration, fatty infiltration in right half of tongue and osseous changes in right maxilla and right zygomatic arch on ultrasound, CT and MRI.
