A rare case of skin metastasis from a chordoma

Area of Science:

• Oncology
• Pathology

Background:

• Chordoma is a rare, slow-growing malignant tumor originating from notochordal remnants.
• Distant metastasis occur in 30-40% of chordoma cases.
• While local skin invasion is common, distant skin metastasis are exceptionally rare.

Observation:

• This clinical case presents a sacral chordoma with a slow-growing progression.
• The tumor initially metastasized to the lungs.
• Subsequently, three years later, skin metastasis developed.

Findings:

• The case illustrates a rare instance of distant skin metastasis from a sacral chordoma.
• It emphasizes the indolent and slow-growing nature of chordoma.
• The occurrence of both lung and subsequent skin metastasis was observed.

Implications:

• This case underscores the importance of considering rare metastatic patterns in chordoma.
• It provides an opportunity to review diagnostic strategies for chordoma.
• Understanding the clinical and histopathological features of rare presentations is crucial for patient management.
