Cutaneous granulomatous vasculitis associated with chronic lymphocytic leukemia: case report and review of literature of a rare entity.

Cutaneous granulomatous vasculitis associated with lymphoproliferative disorders is a rare entity, with only 14 cases previously reported in the English literature. Patients generally present with nodules or ulcers involving the extremities, which can appear months or years before or after onset of systemic disease. Granulomatous vasculitis has a poor prognosis when associated with underlying lymphoproliferative disorders, with the majority of reported cases fatal. Knowledge of this unusual entity is important to allow for proper clinical evaluation, follow-up, and therapy. We report a 77-year-old female with chronic lymphocytic leukemia and granulomatous vasculitis, which highlights the features of this association, and expands the clinical data.
