In-transit metastasis from cutaneous squamous cell carcinoma (SCC) is rare but serious. Management involves surgery and radiotherapy, with a poor prognosis despite treatment.
Area of Science:
- Oncology
- Dermatology
- Surgical Pathology
Background:
- In-transit metastasis from cutaneous squamous cell carcinoma (SCC) is an uncommon lymphatic spread.
- It occurs more frequently in immunosuppressed individuals.
Purpose of the Study:
- To identify cases of in-transit SCC.
- Determine patient characteristics, tumor features, management, and prognosis.
Main Methods:
- A multicenter case series.
- Data collected from Australian and New Zealand clinicians.
Main Results:
- 31 patients with in-transit SCC were analyzed.
- Most tumors (94%) were on the head and neck, particularly scalp, forehead, and temple.
- 5-year survival was poor at 13%.
Conclusions:
- The majority of in-transit SCC patients were immunocompetent.
- Proposed new diagnostic criteria for in-transit SCC.
- Recommended management includes surgery and adjuvant radiotherapy, alongside reducing immunosuppression.

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...
