Perineural spread leading to orbital invasion from skin cancer
1Department of Radiation Oncology, Westmead Hospital, New South Wales, Australia. michael@radonc.wsahs.nsw.gov.au
Abstract:
Orbital and intracranial invasion from skin cancer is an uncommon but serious consequence of skin cancer located around the orbit, particularly the forehead. Perineural spread is an aggressive manifestation of skin cancer similar to lymph node metastases. Such spread can provide access to the orbit and squamous cell carcinoma is the most common histology reported. Treatment should be directed at preventing such orbital spread. Adjuvant radiotherapy is strongly recommended. Disease may present in an advanced state within the orbit or beyond the orbital apex and involve the cavernous sinus. Palliative radiotherapy should be considered in such advanced cases. Presented are the cases of four patients treated for advanced orbital and intracranial spread from periorbital skin cancer.
Insights
Skin cancer invading the orbit and brain is rare but serious. Early treatment and adjuvant radiotherapy are key to preventing spread, with palliative options for advanced cases.
Area of Science:
- Oncology
- Ophthalmology
- Dermatology
Background:
- Skin cancer around the orbit, especially on the forehead, can lead to orbital and intracranial invasion.
- Perineural spread is an aggressive form of skin cancer, mimicking lymph node metastases, and can facilitate orbital invasion.
Observation:
- Squamous cell carcinoma is the most frequent histology reported in cases of orbital invasion.
- Advanced disease may extend beyond the orbital apex, involving the cavernous sinus.
Findings:
- Four patient cases illustrate advanced orbital and intracranial spread from periorbital skin cancer.
- Adjuvant radiotherapy is strongly recommended to prevent orbital spread.
- Palliative radiotherapy is a consideration for advanced cases with intracranial involvement.
Implications:
- Timely diagnosis and intervention are crucial for managing aggressive skin cancer with perineural spread.
- Radiotherapy plays a vital role in both preventing and managing advanced orbital and intracranial invasion.
- Understanding perineural spread patterns is essential for effective treatment strategies in periorbital skin cancers.
