With recent advance in technology, fluorescence in situ hybridization (fish) and reverse transcriptase polymerase chain reaction (rt-pcr) can be done in paraffin embedded tissue. Tumor cells can also be retrieved from fixed tissue by laser capture microdissection and subsequently analyzed by rt-pcr for signature translocations. This is particularly important when frozen tissue is not available as in cases of small biopsies or outside referral cases.

Myopericytoma is a benign tumor showing perivascular myoid differentiation that forms a morphologic continuum with myofibroma, so-called infantile hemangiopericytoma, angioleiomyoma, and glomus tumors. 67,68 myopericytomas arise predominantly in the extremities, head and neck, and trunk of adults.
Hemangiopericytoma is a term used to described a group of tumors that are derived from pericytes, the cells normally arranged along specific types of blood vessels called capillaries and venules. These types of tumors are typically slow-growing, may be either benign (non-cancerous) or malignant (cancerous), and may occur anywhere in the body.

A glut1 stain can be used to additionally support the diagnosis of infantile hemangioma; however, this stain is not entirely specific for infantile hemangioma and can be positive in other vascular lesions of the cns, as well as background red blood cells. 78 cytokeratin may be focally positive in some angiosarcomas, especially with the epithelioid variant. For this reason, cytokeratin staining alone should not be used to differentiate a metastatic carcinoma from angiosarcoma.
