Cutaneous B-cell lymphomas are a malignant proliferation of lymphocytes of the B-cell type. Mutation occurring at different points in B cell development leads to different forms of lymphoma. Rarely, it presents as verrucous plaques or widespread garland-like lesions. They are typically red to bluish. They are mainly found on one or both legs but it affects other sites in 10–15%. It represents an aggressive subtype of PCBCL. Primary cutaneous diffuse large B-cell lymphomas of leg type are rare, occur mainly in very old women, preferentially localize in the lower limbs and in 10 to 15% of cases, they are localized in another part from the body. We describe a case in a 66 year old man with an atypical localization in the left shoulder.
