Abstract:
Leiomyosarcoma (LMS) is a malignant tumor of smooth muscle origin that is most frequently found in the uterus and gastrointestinal tract. LMS involving the head and neck is rare, accounting for only 2.3% of all cases. In this region, LMS tends to be more aggressive and is associated with a poorer prognosis compared to its gastrointestinal counterparts. Furthermore, LMS of the nasal cavity and paranasal sinuses is extremely rare. Here, we present a case of malignant transformation of a leiomyoma originating from the inferior turbinate, which was successfully treated with endoscopic tumor resection followed by postoperative radiotherapy.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
02:07Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
