Hypertrichosis is a common feature in cutaneous porphyrias, characterized by high accumulation of photoreactive porphyrins. Photothermolysis induced by noncoherent light (755-1200 nm) and energy fluence of 42 J/cm(2) was applied to a patient with hepatoerythropoietic porphyria. Hypertrichosis was almost completely removed after seven sessions without development of skin lesions.
