TFE3 activation in a TSC1‐altered malignant PEComa: challenging the dichotomy of the underlying pathogenic mechanisms

open access: yesThe Journal of Pathology: Clinical Research, Volume 7, Issue 1, Page 3-9, January 2021., 2021
Abstract Perivascular epithelioid cell tumors (PEComas) form a family of rare mesenchymal neoplasms that typically display myomelanocytic differentiation. Upregulation of mTOR signaling due the inactivation of TSC1/2 (Tuberous Sclerosis 1 and 2) is believed to be a key oncogenic driver in this disease.
