Epithelioid solitary fibrous tumors from CNS and soft tissues: an unusual morphologic variant.
Diagn Pathol
October 2024
Department of Pathology, Renmin Hospital of Wuhan University, Wuhan, Hubei, 430060, China.
Article Synopsis
- Solitary fibrous tumors (SFTs) are unique soft tissue tumors linked to genetic rearrangements and characterized by specific vessel formations; they can show rare variants, including the malignant epithelioid cell variant.
- The study presented three cases of epithelioid SFTs in elderly patients, mostly female, located in different extrathoracic areas, with malignancy diagnosed in two cases based on tumor cell markers.
- The findings highlight the need for heightened awareness and careful differential diagnosis of epithelioid SFTs due to their atypical cell arrangements, which can confuse pathologists and complicate diagnosis compared to more common tumors.

A rare tumor called hemangiopericytoma develops from the pericytes, the cells that surround blood vessels. They frequently grow slowly and might be asymptomatic initially. Although they can develop anywhere in the body, these tumors are most frequently found in the head, pelvis, and legs.

Department of Endocrinology and Diabetes, Sir Charles Gairdner Hospital, Nedlands, WA 6009, Australia.
Non-islet cell tumor hypoglycemia (NICTH) is a rarely encountered cause of hypoglycemia. It is most often caused by tumor secretion of precursor insulin-like growth factor-2 (IGF-2) which, in high concentrations, binds to insulin receptors exerting insulin-like metabolic effects. It is often associated with mesenchymal and hepatic tumors.
