Cutaneous melanoma with tonsillar metastasis.

Area of Science:

• Oncology
• Pathology

Background:

• Hematogenous dissemination is a rare cause of tonsillar fossa metastases.
• Cutaneous melanoma can metastasize distantly, even years after initial treatment.

Observation:

• A case of cutaneous melanoma with a metastasis to the tonsil is presented.
• The metastasis occurred approximately 4 years after the primary diagnosis.

Findings:

• The tonsillar metastasis was presumed to be due to hematogenous spread.
• The patient's primary disease was treated with palliative radiation therapy.

Implications:

• This case underscores the potential for late and unusual metastatic patterns in cutaneous melanoma.
• Recognizing rare metastatic sites is crucial for accurate staging and prognosis in advanced cancers.
