ABSTRACT
The keloid scar is a pathological lesion characterized by excessive proliferation of collagen
in the papillary dermis that surpasses the original edges of the wound.
Twenty cases of keloid scar were studied (60% women [n = 12] and 40% men [n = 8])
with an average age of 33 over a one year follow-up (May 2010 - May 2011).
The lesions were described using the parameters of the Vancouver scale.
Surgical resection was performed and a simple random selection divided the group into 2 groups:
Group A was treated with Imiquimod cream 5% c/24 h for 8 weeks and
Group B: Triamcinolone 10 - 40 mg/mL each month (4 applications).
Patients were checked on day 7, two weeks and 4 weeks afterwards,
then monthly during the first semester and a year after the procedure.
General improvement in the appearance and characteristics of the
scar was noted with statistical significance (t = 8. 320, gl = 19, p ‹ 0.05).
Comparatively in both groups statistical difference could also be documented
in favor of Imiquimod (F = 8. 337, gl = 9, p ‹ 0.05) compared to Triamcinolone (F = 4. 743, gl = 9, p ‹ 0.05),
also that both groups achieved a favorable tendency in terms of the characteristics
of the scar and decline in the scale of Vancouver.
