Chronic exposure to ultraviolet light causes wrinkles and dyspigmentation. Imiquimod cream is an immune-modulator medication approved for the treatment of genital warts, actinic keratosis, and superficial basal cell carcinoma. Few scientific papers were published in the literature on the effect of imiquimod on photodamaged skin. We report four patients with benign and malignant cutaneous neoplasms who were treated with 5% imiquimod cream and noticed improvement in their skin appearance. We believe that imiquimod cream is a safe and effective option for improving photodamaged skin with excellent safety profile.

| Introduction|| |
Chronic exposure to ultraviolet (UV) light leads to wrinkling and dyspigmentation. Persistence UV exposure causes multiple cutaneous carcinomas. Imiquimod is approved for the treatment of genital warts, actinic keratosis, and superficial basal cell carcinoma (BCC)., Imiquimod is a Toll-like receptor 7 agonist that induces inflammation through the activation of nuclear factor kappa-B (NF-KB).
We report four patients with benign and malignant cutaneous neoplasms who were treated with 5% imiquimod cream and who had improvement in the appearance of their photodamaged skin.
| Case Report|| |
Four patients (mean age: 71.25 years) received 5% imiquimod cream every other day to treat their skin conditions [Table 1]. Patient 1 is a 71-year-old female with biopsy-proven BCC on her left cheek. The patient was treated with imiquimod for 3 months. Patient 2 is a 78-year-old female with seborrheic keratosis on the left check and received treatment for 2 months [Figure 1]a. Patient 3 is a 61-year-old male with biopsy-proven superficial BCC on the lower back. The patient applied the topical medication for 3 months. Patient 4 is a 75-year-old male with biopsy result showing pigmented BCC on the right lateral eyebrow. This patient applied imiquimod cream for 6 months [Figure 2]a.

In addition to resolving of their primary skin condition, our patients had improvement in their skin appearance from their baseline status. Serial photographs on a monthly basis were taking from our patients and showed improvement. Wrinkles and dyspigmentation were better than in baseline photographs [Figure 1]b and [Figure 2]b. Three out of four patients did not have severe skin irritation or major side effects of the medication and therefore completed the treatment duration. Patient 2 had mild skin irritation after 1 week of applying the cream, which resulted in holding the medication and prescribing topical corticosteroid cream for 3 days; imiquimod treatment resumed after 1 month.
| Discussion|| |
Prolonged exposure to UV light results in photoaging of the skin. The mechanism of action of imiquimod in improving photodamaged skin is unclear, as both UV radiation and imiquimod result in activation of NF-KB, complex activator protein-1, and subsequent transcription of proinflammatory cytokines. Imiquimod downregulates matrix metallopeptidase 9 (MMP-9), basic fibroblast growth factor, and vascular endothelial growth factor and upregulates tissue inhibitor of MMP-1. These features might explain how imiquimod works in improving photodamaged skin.
There have been few reports in the literature about use of imiquimod in photodamaged skin. One study of 5% imiquimod cream reported improvement of subjects' photodamaged skin.,, In a meta-analysis, imiquimod cream 2.5% and 3.75% improved appearance. The group treated with 3.75% cream showed more improvement (44.1%) than the 2.5% group (31.9%). They did not include imiquimod cream 5% in their review.
It appears that 5% imiquimod cream is a safe and effective treatment for malignant and premalignant skin cancer, in addition to improving the overall appearance of the skin. In our study, only one patient out of four held the medication temporarily due to irritation. Imiquimod also improves histological appearance of the skin, with correction of the thickness of epidermis, decreases the number of atypical keratinocytes, and decreases solar elastosis.,,,
The lack of histological correlations of our patients is one of our study limitations in addition to small number of subjects.
