Primary malignant fibrous histiocytoma (MFH) of the spleen is extremely rare. Since the first description of primary splenic MFH reported by Govoni et al in 1982, to the best of our knowledge, only twelve cases of MFH of the spleen have been reported in the literature. We herein report a rare case of primary splenic MFH in a 30-year-old Indian male who presented with abdominal pain with a history of recurrent hydatid cyst of liver and spleen. ⋯ On immunohistochemistry, the tumor was positive for vimentin and CD68. The post operative period was uneventful. Compared with the twelve previously cases of MFH of the spleen, our patient is the youngest case reported so far.

We report a case documenting fluorodeoxyglucose (FDG) accumulation in cervical, supraclavicular and axillary lymph nodes resulting from acute toxoplasmosis. A 50-year-old Indian female with history of non-Hodgkin's lymphoma (NHL) of left breast, postchemotherapy status, was found to have hypermetabolic right cervical, supraclavicular and axillary lymph nodes on a surveillance FDG positron emission tomography/computed tomography (PET/CT) scan. Her previous two PET/CT scans were unremarkable with no evidence of metabolically active disease. ⋯ The serological test results were also compatible with acute toxoplasmosis infection. Infective and inflammatory diseases are known to accumulate FDG, resulting in false positives for malignancy. This case demonstrates lymph nodal toxoplasmosis as a potential cause of false positive FDG PET/CT findings in patients with known malignancy and highlights the importance of histopathological and laboratory correlation for the accurate interpretation of FDG PET/CT scans.
