Abstract:
We report a case of a 65-year-old man with newly diagnosed squamous carcinoma of the lung, who presented with worsening left-knee pain. A bone scintigraphy displayed an increased radioactivity in the left patella. The patient underwent left patellectomy. Histopathological examination revealed metastasis to the patella from the known lung cancer.

Metastasis
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...

Tumor 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...
