Infiltrating lipomatosis of the face: A case series
A 20-year-old female presented with complaint of a swelling on the left side of the face, present since birth. There was a previous history of surgery at the age of 5 years for the same complaint. It was provisionally diagnosed as hemifacial hypertrophy as there was associated enlargement of the maxillary alveolus of the same side.\nOn extraoral examination, a swelling was seen on the left side of the face, extending from preauricular region to the lower border of the mandible, measuring approximately 8 × 10 cm in size []. The swelling was soft, non-tender, and fluctuant on palpation. Intraorally, there was enlargement of the left maxillary and mandibular alveolar processes, causing displacement of teeth [].\nIncisional biopsy was done and the gross specimen was received as two soft tissue bits measuring around 1.2 × 1 × 0.5 cm, 2 × 0.5 × 0.5 cm, irregular in outline, creamish brown in color, and soft in consistency. The hard tissue portion (maxillary alveolus) was received as three large-sized hard tissue bits measuring around 2 × 1.5 × 0.5 cm, 1.5 × 0.5 × 0.5 cm, and 0.8 × 0.5 × 0.5 cms, white and brown in color and hard in consistency.\nOn microscopic examination, sections from upper lip and cheek of left side showed large amounts of adipose tissue infiltrating the muscle planes. Numerous blood vessels and extravasated erythrocytes were also observed. Decalcified sections from maxillary alveolus showed adipose tissue within the marrow spaces []. Few resorbed and some normal bony trabeculae were also seen.Incisional biopsy was suggestive of infiltrating lipomatosis.The patient is scheduled for an excisional surgery for esthetic purpose.
