Extramammary Paget disease (EMPD) is a rare intraepithelial adenocarcinoma. The current mainstay of treatment is wide local excision. We present the case of a 56-year-old woman with perianal EMPD that recurred 4 years after initial treatment with wide local excision with Mohs micrographic surgery tissue processing of marginal tissue. Upon recurrence with anal canal involvement, the patient was treated with a 16-week combination course of topical imiquimod and oral cimetidine. There is growing evidence to support both the use of topical imiquimod for the treatment of EMPD as well as the antioncogenic effects of oral cimetidine. We present this case of primary perianal EMPD to highlight an alternative treatment regimen for poor surgical candidates.

Dendritic cell (DC) activation by pattern recognition receptors like Toll-like-receptors (TLRs) is crucial for cancer immunotherapies. Here, we demonstrate the effectiveness of the TLR7/8 agonist imiquimod (IMQ) in treating both local tumors and distant metastases. Administered orally, IMQ activates plasmacytoid DCs (pDCs) to produce systemic type I interferons (IFN-I) required for TLR7/8 upregulation in DCs and macrophages, sensitizing them to topical IMQ treatment, which is essential for therapeutic efficacy.

Psoriasis is a chronic and incurable inflammatory skin disease usually requiring long-term disease management. Natural phytochemical resveratrol (RES) has been known for high efficiency and low toxicity, exhibiting good anti-psoriasis potential. However, its biological activity is limited by poor solubility, chemical instability, and insufficient skin retention.

Psoriasis, a chronic inflammatory skin disease, poses a significant burden on patients' quality of life and healthcare systems. While mild-to-moderate cases are treated topically, usually combined with phototherapy, severe cases require systemic treatment with immunosuppressants, retinoids or biologics. However, all available treatments have drawbacks in terms of efficiency and side effects.

Cutaneous melanoma is a malignant neoplasm with local and distant metastatic potential. When feasible, surgery is the first line of treatment in locoregionally advanced disease. Topical and intralesional treatments can be an alternative second-line treatment.

Inflammatory skin diseases comprise a group of skin conditions characterized by damage to skin function due to overactive immune responses. These disorders not only impair the barrier function of the skin but also deteriorate the quality of life and increase the risk of psychiatric issues. Here, a low-modulus phosphatidylserine-exposing microvesicle (deformed PSV, D-PSV) was produced, characterized, and evaluated for its potential therapeutic function against skin diseases.
