Infiltrating lipomatosis of the face: A case series
A 5-year-old girl presented with the complaint of swelling on the left side of the face since birth with no history of pain or pus discharge. The swelling showed no change in size since birth.\nOn clinical examination, there was a diffuse swelling over left cheek region, extending from infraorbital rim to lower border of mandible and anteroposteriorly from the angle of mouth to 2 cm in front of tragus []. No lymph nodes were clinically palpable. Intraoral examination revealed minor enlargement of alveolar process on the left side, early eruption of 23, 24, 26, and early exfoliation of 63 and 64.\nMagnetic resonance imaging (MRI) showed poorly defined lipomatous lesion on the left side of the cheek, in subcutaneous plane, and buccal pad of fat, with secondary hypertrophy of maxillary alveolus and hyperplasia of left maxillary sinus. No fatty infiltration of muscles was seen [].\nIncisional biopsy was done. On gross examination, the received soft tissue specimen was measuring 1.5 × 0.8 × 0.4 cm in size, and was light brown in color, soft in consistency, and irregular in shape. Histopathologic examination of the section showed collection of adipocytes with scanty fibrous tissue. A diagnosis of infiltrating lipomatosis was given after correlating with the MRI findings.\nThe patient is being kept on a regular follow-up and no treatment has been advocated as the patient is very young.
