The differential diagnoses of IMT include nodular fasciitis, sarcomatoid carcinoma, desmoid-type fibromatosis, inflammatory leiomyosarcoma, inflammatory fibroid polyp, and gastrointestinal stromal tumor (GIST), and these are mostly resolved by a combination of distinctive histological features and their negative staining with ALK1 IHC [1,8]. This evidence concerns the gene ALK and desmoid tumor.
