Cutaneous metastasis from glioblastoma

Area of Science:

• Oncology
• Dermatology
• Surgical Pathology

Background:

• Glioblastoma is an aggressive primary brain tumor.
• Cutaneous metastasis from glioblastoma is exceptionally rare.
• Surgical scars can be a potential site for tumor recurrence or metastasis.

Observation:

• A patient presented with an isolated skin lesion near a previous glioblastoma surgical site.
• The skin lesion was histopathologically confirmed as glioblastoma metastasis.
• No other distant metastatic sites were identified.

Findings:

• The cutaneous metastasis was located adjacent to the surgical scar.
• The pathogenesis likely involves iatrogenic seeding during surgery or local recurrence.
• This finding highlights the importance of vigilant follow-up in glioblastoma patients.

Implications:

• This case expands the known spectrum of glioblastoma metastasis.
• It underscores the need for careful surgical technique and wound monitoring.
• Understanding rare metastatic patterns aids in patient management and prognosis.
