Background: Management of keloid is difficult as well as challenging. Intralesional triamcinolone acetonide (TAC) injections have remained a gold standard in non-surgical management of keloid. TAC is generally used in the concentration of 40mg/ml, which causes adverse effects such as local dermal atrophy and hypopigmentation. Aim was to study efficacy and adverse effects of TAC in treatment of keloid, in a lesser concentration of 20mg/ml.Methods: An open label study was conducted from November 2015 to May 2017 on 25 subjects of either gender, in the age group 11-55 years, at a medical college hospital. Intralesional injection TAC 20 was administered in the keloid at an interval of 3 weeks, for a total of 6 sessions, over a period of 18 weeks. Vancouver scar scale (VSS) was used to assess the improvement and SPSS 21 for statistical analysis.Results: Mean age of keloid subjects was 30.72 years and median duration of keloid was 8 months. The mean VSS score before treatment was 8.36 which reduced to 3.20 after treatment. Mean percentage change in VSS score was 62.79%, which was very highly significant (p <0.001). Physician’s assessment was ‘Very Good’ in 52.0% and ‘Excellent’ in 5 (20%). Adverse effect of atrophy was seen in 3 (12%), hypopigmentation in 11 (44%) and telangiectasia in 4 (16%).Conclusions: Intralesional injection triamcinolone acetonide 20mg/ml gives very good to excellent improvement in the majority of patients of keloid. Local adverse effects seen were hypopigmentation, atrophy and telengiectasia.

<p class="abstract"><strong>Background:</strong> Keloid is a common presentation in clinical practice. Symptoms due to keloid are mild, but disfigurement and functional impairment can be severe. It is difficult to treat. Intralesional, injection triamcinolone acetonide, has limited efficacy, causes adverse effects such as local dermal atrophy, telengiectasia and hypopigmentation. Injection verapamil is reported to have similar efficacy, but lesser side effects, and is cheaper. Aim was to study efficacy and adverse effects of intralesional verapamil in treatment of keloid.</p><p class="abstract"><strong>Methods:</strong> An open label study on 25 patients of keloid, either gender, age 11 to 55 years at a medical college hospital.
