A 32-year-old Black man is referred for evaluation and treatment of growths on his upper back and chest. The majority of lesions have been present for approximately 2 years and some are painful at times. The patient is in good health and denies a family history of similar growths. Examination reveals scattered skin-colored nodules and multiple papules on the patient’s back and chest, as well as less frequent pustules on his face.

Keloids are fibroproliferative growths that extend beyond sites of trauma. These lesions form as a result of excessive accumulation of extracellular matrix components such as collagen in response to aberrant expression of growth factors and cytokines.1 Keloids present as firm papules and nodules.
Keloids may appear at any age but most commonly arise in adolescence through the third decade.2 Patients of African descent are disproportionately affected by the condition; keloids are 15 times more frequently among Black individuals than White individuals.2 Common locations include the earlobes, chest, shoulders, upper back, lower scalp, and posterior neck.
Keloids can significantly impair quality of life.3 Although the majority of keloids are asymptomatic, lesions may interfere with range of motion and may cause pain, itching, bleeding, or ulceration. Further, lesions are often cosmetically disfiguring.
Therapeutic options for the management of keloids range the gamut from application of silicone gel sheeting to surgical excision.4 No treatment is universally successful. One of the most widely used modalities is intralesional injection of triamcinolone; repeated injections at periodic intervals may reduce scar volume and height.
Steroid injections often precede surgical removal, although even with this combined modality, a significant percentage of keloids recur.5 A recently published study documented that single-dose radiation therapy following surgery prevented keloid recurrence in a majority of patients.6
