Diagnostic value of computed tomography (CT) histogram analysis in thyroid benign solitary coarse calcification nodules.

This study was to investigate the diagnostic value of the computed tomography (CT) histogram in thyroid benign solitary coarse calcification nodules (BSCNs). A total of 89 thyroid solitary coarse calcification nodules (coarse calcification ≥5 mm, no definite soft tissue around calcification) confirmed either by surgery or histopathological examination in 86 cases enrolled from January 2009 to December 2015 were evaluated. These included 56 BSCNs and 33 malignant solitary coarse calcification nodules (MSCNs).

[Primary lymphoma of breast: a clinicopathologic, immunophenotypic and prognostic study of 21 cases].

Objective: To investigate the clinicopathologic and immunophenotypic features of primary breast lymphoma (PBL) and to discuss the diagnosis of the tumor.

Methods: Twenty-one cases of PBL with follow up data were clinically reviewed. The histologic diagnosis of the tumor was based on the updated WHO Classification of tumors of hematopoietic and lymphoid tissues (2008).
