چکیده
We read with great interest a recently published article by Lecoutere et al [1] entitled “multifocal cytokeratin expression in pleural and abdominal malignant solitary fibrous tumor: an unusual diagnostic pitfall”. Authors showed three histologically and immunohistochemically welldocumented cases of pleural and abdominal malignant solitary fibrous tumor (SFT) with unexpected multifocal expression of cytokeratin AE1/AE3, which can cause significant diagnostic confusions for practical pathologists.

Solitary fibrous tumor of the thymus with variegated epithelial components.
Solitary fibrous tumor is a rare mesenchymal neoplasm, characterized by peculiar histological features composed by the proliferation of spindle cells in "patternless pattern". Although it has been known to sometimes be accompanied by epithelioid cells, the presence of a well-formed epithelial structure is far more rare. We describe herein the case of a 60-year-old female with the radiological f...
متن کاملA reappraisal of hemangiopericytoma of bone; analysis of cases reclassified as synovial sarcoma and solitary fibrous tumor of bone.
Hemangiopericytoma (HPC) was first described as a neoplasm with distinct morphologic features, presumably composed of pericytes. In soft tissue, it is accepted that most such lesions are solitary fibrous tumors (SFTs), monophasic synovial sarcomas (SSs), or myofibromatoses. It is unclear whether HPC of bone exists. We reviewed 9 primary "HPC" of bone from 4 institutions diagnosed between 1952 a...

Oncocytic metaplasia (OM) is not a well-known feature in inflammatory fibrous hyperplasia (IFH) lesions, although it may be common, as proposed in our previous study about this lesion. In the present paper, we assessed the histopathological and immunohistochemical features of 18 cases of IFH containing OM areas. All the samples were examined on haematoxylin and eosin stained sections and cytoke...
