Primary Cutaneous Diffuse Large B-Cell Lymphoma with Tongue Involvement

A variety of Tand B-cell neoplasm can involve the skin and the term “primary cutaneous lymphoma” refers to the disorder that present in the skin with no evidence of extracutaneous disease at the time of diagnosis [1,2]. Among them, primary cutaneous diffuse large B-cell lymphoma, leg type (PCDLBCL, LT) is characterized with skin lesions on one or both legs. In patients presenting with a single small skin tumor, radiotherapy should be considered [2,3]. Although nonHodgkin’sB-cell lymphoma represents the second leading malignancy of oral cavity, lymphoma involving the tongue is very rare [4,5].
