Cutaneous manifestations of angioimmunoblastic lymphadenopathy.

Angioimmunoblastic lymphadenopathy (AIL) is an uncommon immunoproliferative disorder with a presentation similar to malignant lymphoma but with a benign histopathologic picture. We report a case of a 49-year-old woman with AIL who manifested a pruritic maculopapular eruption as her presenting complaint and whose disease pursued an aggressive clinical course. Forty-four percent of patients with AIL experience a nonspecific dermatitis that in general is maculopapular and precedes other clinical symptoms by at least several weeks. AIL should be included in the differential diagnosis of any maculopapular eruption of unknown etiology accompanied by lymphadenopathy.
