Deoxycholic Acid as a Minimally Invasive Treatment for a Giant Dorsal Lipoma: A Case Report

A 39-year-old woman presented with a 14.0cm by 10.0cm lipoma on the left posterior-lateral flank. Conventional treatment for lipomas includes excision, but this poses a risk of extensive scarring in patients with large lipomas. Deoxycholic acid (DCA) injections are a viable non-surgical alternative to reduce the size of lipomas. The patient received two rounds of intralesional DCA injections three months apart, with each using 8.5mL of 10mg/mL solution. Four months after beginning treatment, she noticed a 50% reduction in the size of the lesion. This case highlights the potential for using DCA injections as a safe, effective treatment to significantly reduce the volume of large lipomas without surgical scarring.
