“…PDT is a minimally invasive procedure that is clinically used in the treatment of several oncologic human diseases, such as skin, esophageal, head and neck, lung, and bladder cancers [ 57 ]. However, PDT also has several non-oncologic applications [ 58 ], including the treatment of non-cancerous human diseases, such as dermatologic (acne [ 59 ], warts [ 60 ], photoaging [ 61 ], psoriasis [ 62 ], vascular malformations [ 63 ], hirsutism [ 64 ], keloid [ 50 ], and alopecia areata [ 65 ]), ophthalmologic (central serous chorioretinopathy [ 66 ] and corneal neovascularization [ 67 ]), cardiovascular (atherosclerosis [ 68 ] and esophageal varix [ 69 ]), dental (oral lichen planus [ 70 ]), neurologic (Alzheimer’s disease [ 71 ]), skeletal (rheumatoid arthritis [ 72 ]), and gastrointestinal (Crohn’s disease [ 73 ]).…”
