A hemangiopericytoma is a type of soft-tissue sarcoma that originates in the pericytes in the walls of capillaries.When inside the nervous system, although not strictly a meningioma tumor, it is a meningeal tumor with a special aggressive behavior. Sinonasal-type hemangiopericytoma is an uncommon upper aerodigestive tract tumor of uncertain cellular differentiation. We report 104 cases of sinonasal-type hemangiopericytoma diagnosed between 1970 and 1995 from the files of the Armed Forces Institute of Pathology. Se hela listan på radiopaedia.org Hemangiopericytoma is a term formerly used to describe a continuum of mesenchymal tumors with elevated cellularity found throughout the body in soft tissue and bone.After many years of controversy, hemangiopericytomas have been shown to not only share histological features similar to solitary fibrous tumors but also similar genetic alteration: genomic inversion of 12q13 locus resulting in 2021-03-02 · WebPathology is a free educational resource with 11065 high quality pathology images of benign and malignant neoplasms and related entities.

The Hemangiopericytoma tumor can occur anywhere in the body. Muscle tissues are most frequently affected, whereas subcutaneous and dermal hemangiopericytoma tumor growth is less frequent 3,5. Hemangiopericytoma (HPC) is an uncommon neoplasm characterized by a dense, blunt spindle-cell proliferation with a richly vascular stroma. Supporting blood vessels often assume a staghorn configuration. The ovoid tumor cells of hemangiopericytomas are rather nondescript and may cause confusion with those of other soft tissue tumors (Fig.

Supporting blood vessels often assume a staghorn configuration. The ovoid tumor cells of hemangiopericytomas are rather nondescript and may cause confusion with those of other soft tissue tumors (Fig. 4.5). Dilated, branching, hyalinized staghorn-like (hemangiopericytoma-like) vasculature Hyalinized to collagenous stroma, sometimes with streaming of cells between collagen Myxoid changes can be prominent (Mod Pathol 1999;12:463) Lipomatous variant contains variable amount of fat (Am J Surg Pathol 1999;23:1201) General Pathology Cells in hemangiopericytomas are derived from pluripotent perivascular mesenchymal cells and resemble pericytes, with few cytoplasmic organelles. Thin-walled, branching blood vessels, also known as “staghorn” vessels, are characteristic of hemangiopericytomas. Nuclei are often ovoid or spindle shaped. In particular, questions exist regarding the synonymity of a hemangiopericytomatous growth pattern--defined by a monomorphic population of compact polygonal or bluntly fusiform cells and a branching stromal vascular pattern with a "staghorn" configuration--and the presence of a reproducible biological entity.
