Non‐Operable Squamous Cell Carcinoma of the Infraorbital Region Treated With Electrochemotherapy: A Case Report

Clinical Case Reports, Volume 14, Issue 2, February 2026.
ABSTRACT Cutaneous squamous cell carcinoma (cSCC) is a malignant epithelial tumor of the skin, classified as a nonmelanoma skin cancer. It may develop from precancerous conditions such as chronic inflammatory dermatoses, actinic keratosis, or actinic cheilitis, but can also arise de novo.

Photodynamic Diagnosis and Therapy in Dermatology

Skin Pharmacology and Physiology, 1998
The topical application of δ-aminolevulinic acid (ALA) induces porphyrin formation in the skin, preferentially in tumor tissues. Irradiation of the porphyrin-enriched tumor tissue with Wood’s light leads to emission of a brick-red fluorescence. This principle may be used as a diagnostic procedure which may be termed photodynamic diagnosis (PDD). In ALA-

Photodynamic diagnosis in the gastrointestinal tract

Gastrointestinal Endoscopy Clinics of North America, 2004
Clinical data on photodynamic diagnosis for the detection of premalignant and malignant lesions in the gastrointestinal tract are encouraging so far. A major benefit of using autofluorescence is the lack of side effects because no sensitizer has to be applied.However, highly sophisticated detection systems are needed to enhance the weak ...

Photodynamic Diagnosis and Therapy in Gynecology

Journal of Environmental Pathology, Toxicology and Oncology, 2008
Photodynamic diagnosis (PDD) and therapy (PDT) are modern methods that are evaluated in different fields in gynecology. PDD is currently under investigation in gynecologic conditions such as cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), endometriosis, and ovarian cancer.

FCLA-assisted photodynamic diagnosis

SPIE Proceedings, 1999
Conventional Photo-Dynamic Diagnosis (PDD) has several serious limitations, such as autofluorescence disturbance, poor penetration ability of the exciting laser etc. All these problems are because the exciting laser wavelength at the main absorption peak of the photosensitizer (e. g. HpD) is too short.
