PEComa With MITF Overexpression

Abstract excerpt

Perivascular epithelioid cell neoplasms (PEComas) are tumors of uncertain cell lineage that occur across a wide age range, at a variety of anatomic sites, and with a female predominance. Most PEComas are associated with dysregulation of the mTOR pathway, most commonly through inactivating mutations of TSC2 or TSC1 . However, a small subset of PEComas are instead associated with TFE3 gene fusions. MITF is closely...
