Granulomatous infiltrates, including granuloma annulare-like changes, in patients with T-cell non-Hodgkin's lymphoma and Hodgkin's disease are well described but are exceedingly uncommon in B-cell non-Hodgkin's lymphoma. Herein, we describe a 73-year-old male with a 10-year history of B-cell chronic lymphocytic leukemia who developed erythematous annular plaques symmetrically on his upper extremities. Biopsies of these lesions revealed both granuloma annulare-like areas, in conjunction with nodular atypical lymphoid infiltrates consistent with secondary involvement by B-cell chronic lymphocytic leukemia. To our knowledge, this is the first report of cutaneous lesions resembling granuloma annulare with concomitant involvement by B-cell chronic lymphocytic leukemia. Awareness of this association may prevent nonrecognition of a neoplastic B-cell infiltrate in a granuloma annulare-like process.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
