Unusual presentation of a Merkel cell carcinoma

Area of Science:

• Dermatology
• Oncology

Background:

• Merkel cell carcinoma (MCC) is a rare, aggressive skin cancer primarily affecting elderly individuals on sun-exposed areas.
• MCC has a high risk of local recurrence, metastasis, and significant mortality.

Observation:

• A case of MCC presented as a 2-mm crusted erosion on the nose.
• This represents the smallest reported case of MCC in the medical literature.

Findings:

• The small tumor size created a management dilemma due to a lack of prospective data.
• Limited information exists on biologic markers for prognostic significance in early-stage MCC.

Implications:

• Highlights the challenge of managing extremely early-stage Merkel cell carcinoma.
• Underscores the need for further research into prognostic markers and treatment strategies for MCC.
