The Expressions of TGF-β(1) and IL-10 in Cultured Fibroblasts after ALA-IPL Photodynamic Treatment.

Background: Topical photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA) was originally used for treating superficial skin tumors. The application of PDT to other inflammatory dermatoses like acne vulgaris, psoriasis, granuloma annulare, localized scleroderma and lichen sclerosus has recently been introduced. However, the underlying mechanisms are not well understood.

Localized Sweet's Syndrome in an Irradiated Field.

Sweet's syndrome is a reactive dermatosis characterized clinically by fever, leukocytosis, and multiple, erythematous, painful plaques. Histopathologic examination reveals a band-like dense dermal inflammatory infiltrate composed mainly of neutrophils with papillary dermal edema, and no features of vasculitis. We report a case of a 56-year-old female diagnosed with cervical cancer, who underwent surgery and concurrent chemoradiation therapy.
