A woman with type I diabetes and Hashimoto’s disease presented necrobiosis lipoidica at 15 years of age. Cyclosporine 100 mg/day was prescribed; however, an abscess in the inguinal region led to treatment interruption. Then, she tried dimethyl fumarate at increasing doses up to 120 mg/day. The lack of results led to the discontinuation of the therapy. The third attempt was isotretinoin 40 mg/day for eight months, with wound healing. Recently, after a knee scar repair surgery, necrobiosis lipoidica lesions appeared at the suture site. The patient received isotretinoin 40 mg/day again, and the lesion regressed in three months.

We developed a narrative literature review on the association of fat grafting and hair transplantation using the Follicular Unit Extraction (FUE) technique in scalp scars. Data were collected from studies found in Medline, Lilacs, and IBECS databases. Bibliographical records of several authors who researched mesenchymal cells in adipose tissue were cited, describing the techniques used. The conclusion was that the two-stage hair transplantation technique, with previous fat transplantation, is effective, according to the reviewed articles.
