Plasmablastic lymphoma is a variant of non-Hodgkin lymphoma, a primary cutaneous diffuse B-cell lymphoma, other type large cell. Uncommon, it mainly affects patients infected with the human immunodeficiency virus (HIV). It tends to occur in the oral cavity. Occasionally it is also described in patients not infected with HIV and in locations other than the oral cavity. It is a diagnostic challenge for the dermatologist due to the low incidence and clinical polymorphism associated with HIV infection. We present the case of a 23-year-old patient with an atypical presentation of this disease associated with HIV infection.
