We report the case of a middle-aged HIV-positive man who presented with proptosis and retro-ocular pain. On CT and MR imaging, a retro-orbital enhancing mass was seen, and PET/CT revealed this lesion as well as a similarly characterized mass in the nasopharynx to be hypermetabolic. Biopsy and subsequent pathological characterization revealed this mass to be plasmablastic lymphoma (PBL), a rare ...

DLBCL: diffuse large B-cell lymphoma PBL: plasmablastic lymphoma PG: pyoderma gangrenosum INTRODUCTION Pyoderma gangrenosum (PG) is an uncommon neutrophilic dermatosis characterized by the rapid development of painful, ill-defined ulcerations with undermined gun-metal gray borders. Although half of the cases are idiopathic, PG may be associated with inflammatory bowel disease, connective tissue...

Plasmablastic lymphoma is a rare and a relatively new entity that was first described in the jaws and the oral cavity of HIV-AIDS patients. We report a case of plasmablastic lymphoma involving the liver in an AIDS patient. Plasmablastic lymphoma is considered a diffuse large B-cell lymphoma with a unique phenotype and predilection for the oral cavity. The case presented had a unique hepatic les...

BACKGROUND Human herpesvirus 8 (HHV8)-positive plasmablastic lymphoma is a disease which correlates with acquired immunodeficiency syndrome (AIDS). Little is known about the pathogenesis of the disease due to its rarity. We report an autopsy case about AIDS related HHV-8-positive plasmablastic lymphoma and presents an examination about HHV8 related proteins for the disease by using immunohistoc...

Plasmablastic lymphoma is a non-Hodgkin lymphoma characterized by its plasmacytic differentiation and predilection for the oral cavity. It is among the lymphomas most commonly associated with AIDS. This report details a case of a HIV-positive patient with a 1-month history of an exophytic mass in the gingival area of the upper left quadrant. The diagnosis of plasmablastic lymphoma was made base...

Plasmablastic lymphoma (PBL) is a rare subtype of diffuse large B cell lymphoma (DLBCL), often associated with HIV infection. We present a case of a 53-year-old HIV-negative man with untreated hepatitis C viral infection who presented with abdominal pain and lymphadenopathy. Lymph node and bone marrow biopsies were consistent with plasmablastic lymphoma. He had partial response (PR) to 6 cycles...

E-mail: [email protected] Abstract Introduction: Plasmablastic lymphoma, a rare and aggressive form of Non-Hodgkins lymphoma, rarely presents as a retroperitoneal mass. There are no case reports in the literature of plasmablastic lymphoma presenting in living, HIV-negative patient status post liver transplantation. Presentation of Case: We report the case of a 63 year-old HIV-negative mal...

Plasmablastic lymphoma (PBL) is a rare B-cell lymphoma occurring mainly in HIV patients. The tumor frequently involves extranodal sites such as the oral cavity, nasal cavity, gastrointestinal tract, skin, and lungs. The neoplastic cells are characterized by a plasmablastic appearance and typical immunophenotype that indicates plasma cell differentiation. Herein, we report a case of intraocular ...

INTRODUCTION We describe here an unusual presentation of a plasmablastic lymphoma in a patient suffering from an osteoradionecrosis of the jaw. PRESENTATION OF CASE We report the case of a 64-year-old patient who was followed up on oncology because of an oropharyngeal cancer treated by a combined procedure of both surgery and radio-chemotherapy procedure. This patient developed an osteoradion...
