Unattractive periauricular widened or hypertrophic scars can result from the tension on rhytidoplasty incision sutures. During a 5-year retrospective study, 10 female patients with such scars were treated with the periauricular ring technique. Polytetrafluoroethylene and double 2-0 mono nylon threads were used in 6 and 4 cases, respectively, introduced with a fascia lata non-bevelled needle . Following the scar exeresis, the borders were approximated and the ring tied and attached to the temporal muscle fascia.The outcomes were satisfactory. In 2 cases the threads were removed without altering the scars’ final aesthetic result.

Introduction: Several therapeutic modalities have been used to treat keloids and hypertrophic scars. Objective: Treatment of keloids and hypertrophic scars with excision and intralesional injection of methotrexate. Methods: Therapeutic intervention open study with 11 patients. Laboratory tests and photographs were carried out before, during, and after the treatment. From the seventh day after the excision of the lesions, the suture was injected weekly with methotrexate for six months. The weekly dose was 2.5 mg / 10cm suture, with a maximum dose of 5mg per patient. The evaluation was carried out by the physician and the patient. Results: Six months after the end of the treatment, there was no recurrence of the lesion in five cases, partial recurrence in six cases and an absence of cases with total recurrence. No alterations were observed in the laboratory tests. Conclusions: The maximum weekly dose of 5mg methotrexate for six months used in this pilot study to treat keloids and hypertrophic scars is safe and hinders recurrence. Further studies are needed to complement the present paper.

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.
