• Photoallergic contact dermatitis developed in a patient who had used deodorant soaps containing tribromsalan. He persistently reacted to light, since the dermatitis persisted long after cessation of contact with the causative chemical. During this period, he experienced generalized, eczematous dermatitis on several occasions. On testing, the patient showed extremely severe photosensitivity extending through the ultraviolet to the visible spectrum. At that time, a skin biopsy specimen showed the microscopic findings of eczematous dermatitis. A diagnosis of actinic reticuloid was first made histologically nine years after the initial examinations, when the patient was 56 years old. This long-term follow-up study may support the view that photoallergic contact dermatitis, persistent light reaction, and actinic reticuloid could constitute various phases of a single disease.
