ALA-PDT for the treatment of cutaneous pseudolymphoma: a case report.

Cutaneous pseudolymphoma (CPL) is a benign skin condition that may cause cosmetic disfigurement, severe itch and, albeit rarely, transformation to malignant lymphoma. The usual treatment modalities for CPL have been associated with adverse effects including skin atrophy and scarring. This article reports the case of a patient with CPL on the cheek, which was treated with 5-aminolevulinic acid photodynamic therapy (ALA-PDT). Clinically significant improvement in lesion size and symptoms was noted, with few side effects. Controlled trials and long-term monitoring are warranted to further explore this treatment modality for CPL.
