We report on the characteristics of 21 cases of Hepatosplenic γδ T-cell lymphoma (HSγδTCL), an entity recognized since 1994 by the REAL classification. Median age was 34 years. Patients presented with splenomegaly (n=21), hepatomegaly (n=15) and thrombocytopenia (n=20). Histopathologic findings were homogeneous with the presence of medium-sized lymphoma cells within the sinusoids of splenic red...
We report on the characteristics of 21 patients with hepatosplenic T-cell lymphoma (HS TCL), an entity recognized since 1994 in the Revised European American Lymphoma (REAL) classification. Median age was 34 years. Patients had splenomegaly (n 21), hepatomegaly (n 15), and thrombocytopenia (n 20).

BACKGROUND Pseudolymphomatous folliculitis is a lymphoid proliferation that clinically and histopathologically mimics primary cutaneous extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma).

Methods. Twelve consecutive patients with resectable, primary high grade bone sarcomas were enrolled prospectively. FDG-PET/CT imaging was performed prior to the initiation and after completi...
