Infiltrating lipomatosis of the face: A case series
A 77-year-old male reported to the outpatient department, complaining of a swelling in the right cheek region since 30 years, with no history of pain or pus discharge. Patient revealed a previous history of liposuction 7 years ago for the same complaint.\nOn extraoral examination, a swelling was seen on the right cheek, extending from preauricular region to the lower border of the mandible, measuring approximately 8 × 10 cm in size []. Intraorally, it covered the entire right buccal mucosa []. The swelling was soft, non-tender, and fluctuant on palpation.\nIncisional biopsy was done which was suggestive of infiltrating lipomatosis, following which the patient underwent surgical removal of the lesion. Excised tissue was submitted to the Department of Oral Pathology as multiple soft tissue bits, with the largest bits measuring around 5 × 3 and 5 × 2 cm in size, brown and yellow in color, irregular in outline, and firm in consistency [].\nOn microscopic examination, large amounts of adipose tissue composed of empty appearing adipocytes with peripherally placed nuclei were seen. The fatty tissue was seen infiltrating through muscle planes and associated with neurovascular bundles. Numerous thick-walled arteries and nerve bundles were observed surrounded by adipose tissue []. Areas of fibrosis and hemorrhage were also noted. The final diagnosis was suggestive of infiltrating lipomatosis.
