Metastasis02:30

Metastasis

6.9K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
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

7.9K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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...

Area of Science:

  • Pulmonology
  • Oncology
  • Vascular Medicine

Background:

  • Pulmonary hamartomas are common benign lung tumors, typically asymptomatic.
  • Rarely, they can present with life-threatening symptoms due to location and vascularity.

Observation:

  • A 27-year-old non-smoker presented with dyspnea, cough, hemoptysis, and weight loss.
  • A right hilar mass involving the bronchus, pulmonary artery, and esophagus was identified.
  • Diagnosis of diffuse vascular hamartoma was confirmed via surgical biopsy.

Findings:

  • The benign lesion was large and extensively involved vital structures.
  • Surgical resection was not feasible due to the tumor's size and vascularity.

Implications:

  • This case underscores the potential for benign pulmonary hamartomas to cause severe morbidity and mortality.
  • Management of large, infiltrative, or vascularly involved hamartomas presents significant clinical challenges.
  • Further research into less invasive treatment options for complex pulmonary hamartomas is warranted.
