Clinical evaluation of a patient of parapsoriasis en plaques who achieved complete response rapidly 4 weeks after hydrogen-water bathing. A 35-year-old man with large plaque parapsoriasis had been followed up for 30 months and during that time two biopsies were taken showing no progression. He had suffered flare-up after 10-month narrow-band UVB therapy and failed to have evident improvement in the later 6-month phototherapy despite of increasing the power. Even if only 4 weeks, his lesions rapidly achieved significant improvements without concomitant therapy (a). The Hematoxylin-eosin stain shows mildly hyperkeratotic and focally parakeratotic epidermis with moderately dense superficial perivascular infiltrate. Lymphoid cells are mostly small, cytologically normal lymphocytes, and there is focal single-cell epidermotropism (b).
