Combination intralesional protocols displace corticosteroid monotherapy
Injecting triamcinolone alone works reasonably and recurs often enough that dermatologists kept looking for better. Combining it with fluorouracil, or using bleomycin or verapamil in resistant lesions, produces recurrence rates that clinicians observe directly in their own patients and share at conferences. Growth at 12.0% follows that diffusion of practice rather than any marketing campaign, since none of these agents is licensed for the indication and nobody promotes them. The commercially awkward consequence is that a generic injectable manufacturer captures the volume growth while contributing nothing to the clinical development at all.
