Granulomatous cutaneous reactions are well described in association with T-cell non-Hodgkin lymphoma and Hodgkin lymphoma, but are rarely seen in association with B-cell non-Hodgkin lymphoma or leukemia. We report a case of a 65-year-old woman with B-cell chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who presented with multiple, tender, firm pink papules on the face, upper trunk and upper extremities 6 years after diagnosis of CLL. Biopsy revealed both palisading granulomatous dermatitis consistent with actinic granuloma and a dense perivascular lymphocytic infiltrate consistent with the patient's known history of leukemia. This is an unusual manifestation of cutaneous B-cell CLL that is rarely seen.
