TFE3 is an immunostain used in uropathology and soft tissue pathology.
The reliability of the immunostain for detecting TFE3 rearrangments has been questioned by at least one study.[1]
Negative
- Normal tissue.[2]
- Staining in normal tissue described as "extremely rare" - negative in adrenal gland, breast, colon, gallbaldder, lymph node, liver, prostate and skin.[3]
Positive
- Xp11.2 translocation carcinoma.
- Alveolar soft part sarcoma.
- YAP-TFE3 translocated epithelioid hemangioendothelioma
- Epithelioid angiomyolipoma.
- Granular cell tumour.[4]
