Right Answer | RightAnswer::A |
Explanation | [[Explanation::The patient is presenting with a keloid scar. Hypertrophic scars and keloids are characterized by the high rates of recurrence following excision by surgery. Treatment options for keloids are numerous with varying rates of success. Intralesional corticosteroids are considered the mainstay of therapy for hypertrophic keloid scars. Other first line options include silicone sheeting and pressure dressingss, whereas ptients with smaller lesions may benefit from cryotherapy. Surgical resection is reserved for large scars that are unlikely to improve with any first line treatment option. However, surgical excision alone exacerbates the keloid scar. Thus, surgery must be combined with other treatment modalities, such as radiotherapy, pulsed dye lasers, or imiquimod creams. Novel therapies are currently emerging for the treatment of established keloid scars, including intalesional calcium channel blockers, such as verapamil, and chemotherapeutic agents, such as fluorouracil and bleomycin injections. Educational Objective: Intralesional corticosteroids are helpful as first line agents for treatment of keloid scars. |
