TFE3
Immunostain in short
Use screen to detect TFE3 rearrangements
Subspeciality urologic pathology, soft tissue pathology
Normal staining pattern nuclear stain
Positive Xp11.2 translocation carcinoma, alveolar soft part sarcoma
Negative normal tissues

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
