Primary PEComa of the bladder treated with primary excision and adjuvant interferon-alpha immunotherapy: a case report

BMC Urology, 2006
Background Perivascular epithelioid cell tumors (PEComas) are rare mesenchymal neoplasms of uncertain malignant potential, which have in common the co-expression of muscle and melanocytic immunohistochemical markers.

Uterine lymphangioleiomyomatosis in a premenopausal woman with tuberous sclerosis: A case report

Case Reports in Women's Health
Lymphangioleiomyomatosis is a rare disease characterized by abnormal smooth muscle cell growth. It primarily occurs in the lungs but can also rarely occur in other organs, in which case it is classified as extrapulmonary lymphangioleiomyomatosis.

TSC2-mutated perivascular epithelioid cell tumor with partial response to mTOR inhibition: a case report and literature review

Discover Oncology
Perivascular epithelioid cell tumors (PEComas), rare mesenchymal neoplasms with heterogeneous behavior, are molecularly characterized by TSC2 inactivation driving mammalian target of rapamycin (mTOR) pathway activation.

MiT fusions, TSC1–TSC2 divergence, and stem-like programs reveal distinct origins and vulnerabilities in PEComa

Nature Communications
Perivascular epithelioid cell neoplasms (PEComas) are ultra-rare mesenchymal tumors lacking a molecular classification to guide therapy. Here we perform comprehensive multi-omic profiling of an unselected PEComa cohort.
