TFE3 is an immunostain used in uropathology and soft tissue pathology.
Negative
- Normal tissue.[1]
- Staining in normal tissue described as "extremely rare" - negative in adrenal gland, breast, colon, gallbaldder, lymph node, liver, prostate and skin.[2]
Positive
- Xp11.2 translocation carcinoma.
- Alveolar soft part sarcoma.
- YAP-TFE3 translocated epithelioid hemangioendothelioma
- Epithelioid angiomyolipoma
- Granular cell tumor[3]
