Richter syndrome (RS) is characterized by the development of a high-grade lymphoma in patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Herein, we present the case of an 85-year-old woman with a 3-year history of stable asymptomatic CLL that developed a cutaneous RS. The patient presented with painless inflammation in the left leg and foot that was initially diagnosed as a cellulitis infection. She was treated accordingly with ceftriaxone and clindamycin. However,

The histopathological examination of the nodules revealed a large B-cell cutaneous lymphoma. The patient underwent chemotherapy with CVP, followed by R-CHOP, resulting in a reduction of size of the nodules and remission of the inflammation. The patient died five months after the diagnosis owing to a bacterial pneumonia. We identified in previous reports a total of fifteen cases of cutaneous RS. Most cases presented with rapidly growing tumors or multiple erythematous nodules, similar to our case. This case of a cutaneous RS mimicking a cellulitis infection underlines the importance of a low threshold for performing biopsies of suspicious skin lesions in patients with CLL/SLL.
