REPORT OF A CASE
A 43-year-old homemaker with recently diagnosed immunoblastic lymphoma, stage III-A, and chronic active hepatitis, who had recently completed her second cycle of chemotherapy (including bleomycin sulfate, doxorubicin hydrochloride, cyclophosphamide, vincristine sulfate, and prednisone), presented with a markedly pruritic eruption over the neck and back. Lesions first developed on the patient's neck and were described as "papular" and "vesicular"; subsequently the eruption spread to a large area of the back and consisted of large, brightly erythematous linear plaques and patches. There were no aggravating or alleviating factors.Physical examination revealed circumscribed wide linear erythematous plaques and patches located over the posterior aspect of the patient's neck (Fig 1) and lower part of the back (Fig 2). There was no evidence of scale or atrophy. Results of the remainder of skin and mucous membranes examination were unremarkable.What is your diagnosis?
"Flagellate" erythema secondary to bleomycin therapy.
