A 54-year-old woman was admitted with compression fracture of thoracic vertebral bodies. Urine protein electro-phoresis revealed the presence of M protein and serum free κ/λ ratio was 0.01. Bone marrow aspiration (A) and biopsy (B) revealed diffuse infiltrat...

Disseminated alveolar echinococcosis mimicking a metastatic malignancy.

Alveolar echinococcosis, which is caused by Echinococcus multilocularis, is a very aggressive and potentially fatal infestation which always affects the liver primarily and metastasizes to any part of the body. Imaging studies are usually highly suspicious of carcinoma or sarcoma, and biopsy may provide the first indication of infection. We report a case of disseminated alveolar echinococcosis ...

Plasmablastic Lymphoma Mimicking Acute Pancreatitis

Background. Plasmablastic lymphoma (PBL) is a rare B-cell neoplasm. It predominantly occurs in the oral cavity of human immunodeficiency virus (HIV)-positive patients and exhibits a highly aggressive clinical behavior. Case Presentation. We describe an unusual case of a 37-year-old HIV-positive male who presented with acute pancreatitis secondary to multiple peripancreatic masses compressing th...

Cecal Giant Lipoma Mimicking Malignancy

Duodenal localization of plasmablastic myeloma

Gastrointestinal involvement in plasma cell neoplasms, either as primary localizations (extramedullary plasmacytomas) or as secondary involvement in systemic multiple myeloma, is a well-known event. Accurate histological examination is crucial in defining the diagnosis. In this report, an uncommon case of duodenal localization of myeloma with plasmablastic features is described, with emphasis o...
