Primary cutaneous diffuse large B-cell lymphoma, leg type is a type of non-Hodgkin lymphoma. It is a fast-growing and aggressive cancer, therefore early diagnosis and treatment is crucial. It is a cutaneous lymphoma that secondarily invades and involves the bone as it progresses. It has been reported in the calcaneus, tarsal bones, lesser metatarsals, and ankle. Herein we present a case of primary cutaneous diffuse large B-cell lymphoma, leg type that was diagnosed from a metatarsal bone biopsy.
