A 56-year-old female patient with generalized granuloma anulare was tr
eated with bath-PUVA therapy with 8-methoxypsoralen. Her diabetes mell
itus renal insufficiency excluded oral photochemotherapy, A series of
30 treatments resulted in complete disappearance of the lesions on the
trunk and neck and significant improvement of those on the limbs. No
side-effects were observed. Bath-PUVA therapy seems to have positive e
ffects not only on epidermal, but also on dermal processes.
